Description

Service data transmission method and device

technical field

The invention relates to the technical field of the Internet, in particular to a service data transmission method and device.

Background technique

With the rapid development of Internet technology, more and more terminals such as computers, mobile phones, and tablet computers have appeared, and these terminals can use the Internet for business data transmission. When terminals use services such as video communication, video-on-demand, and web page browsing, in order to obtain service data, these terminals need to transmit service data through the Internet.

At present, when a terminal uses the Internet to transmit service data, the application layer of the terminal sends the service requirement parameters required by the service to be used to the transmission service layer (English: Transport Layer, TAPS for short), and the service requirement parameters refer to The parameters required when the service is in a normal state, that is, the threshold parameters that can be tolerated when the service is in a normal state, this parameter may include transmission delay, packet loss rate, throughput rate, etc., when TAPS receives the In the case of service requirement parameters, based on the service requirement parameters, determine the terminal’s transmission protocol for transmitting the service, and configure corresponding transmission parameters for the transmission protocol, and then, the terminal’s transmission layer is based on the transmission protocol and transmission The parameter service data transmission establishes a transport layer connection with the communication peer for the service, and transmits the service data of the service through the transport layer connection.

Since TAPS determines the transport protocol for the transport layer of the terminal based on the service requirement parameters and configures the corresponding transport parameters, once the transport status of the transport layer changes or the network is congested, the transmitted service data will be lost , thereby reducing the speed and quality of business data transmission.

Fig. 3 is a flowchart of a service data transmission method provided by an embodiment of the present invention. Referring to Figure 3, the method includes:

Step 301: During the process of the transport layer transmitting the service data of the first service through the first transport protocol and the first transport parameters, the transport service layer receives transmission status information, the transmission status information includes at least transport layer status information, the first transport protocol and the first transmission parameter are the transmission protocol and transmission parameters currently configured for the transport layer.

When the terminal is using services such as video communication, video on demand, and web browsing, in order to obtain the data required by the service, the terminal needs to transmit service data through the network, and because the service data is transmitted, it will be affected by the transport layer. The impact of state changes, for example, when transmission congestion occurs at the transport layer, it will cause problems such as data packet loss and data packet transmission delay. and the transmission parameters, the transmission service layer of the terminal needs to receive the transmission status information of the information during transmission.

In addition, in the process of business data transmission, not only the transmission status of the transport layer will have an impact on the business data transmission, but also the network status of the network layer will also have an impact on the business data transmission. For example, when network congestion occurs at the network layer, It will also cause problems such as data packet loss, data packet transmission delay, etc. Therefore, the transmission status information may not only include the status information of the transport layer, but also include the status information of the network layer.

Further, before the transmission service layer receives the transmission status information, the transmission service layer can make the transmission layer or the network layer report the current transmission status information to the transmission service layer through the following three methods (1)-(3), as follows stated.

(1), the transmission service layer receives the service requirement parameter sent by the application layer, and the service requirement parameter is the parameter required when the first service provided by the application layer is in a normal state, and obtains the threshold parameter from the service requirement parameter , based on the threshold parameter, register a key event with the relevant layer, and the key event is used to report the transmission status information to the transmission service layer when the transmission parameter of the relevant layer exceeds the threshold parameter, and the relevant layer includes at least the transmission layer.

Since the service requirement parameter includes the minimum threshold parameter that can be tolerated when the first service is in a normal state, during the service data transmission process, if the transmission parameter used for transmitting information exceeds the minimum threshold parameter, the terminal is performing the first service. There will be various problems in the process of a business, resulting in the failure of the first business. Therefore, in order to ensure the normal use of the first business, after the transmission business layer receives the business requirement parameters sent by the application layer, it can The threshold parameter is obtained from the business requirement parameter. Based on the threshold parameter, the transport service layer registers a key event with the relevant layer. After the key event registration is successful, when the transmission parameter used for business data transmission exceeds the threshold parameter, the relevant layer Report the current transmission status information to the transmission service layer.

Wherein, since the service requirement parameter may include multiple parameters, when the transport service layer obtains the threshold parameter from the service demand parameter, the transport service layer may determine the service identifier of the first service currently provided by the application layer, and based on The service identifier of the service currently provided by the application layer obtains the corresponding parameter identifier from the stored correspondence between the service identifier and the parameter identifier, and based on the obtained parameter identifier, obtains from the multiple parameters included in the business requirement parameter corresponding parameters, and determine the obtained parameters as threshold parameters.

During the service data transmission process, some request messages will be transmitted between the application layer and the transport service layer, and the request message may carry the service identifier of the first service currently provided by the application layer. Therefore, the transport service layer can obtain from these The service identifier of the service currently provided by the application layer is obtained from the request message. For example, the request message may be a connection establishment message, which is not specifically limited in this embodiment of the present invention.

It should be noted that the service identifier is used to uniquely identify the first service currently provided by the application layer, and the service identifier may be the service name, service number, etc. of the first service currently provided by the application layer. The example does not specifically limit this.

It should also be noted that the parameter identifier is used to uniquely identify the parameter, and the parameter identifier can be the name of the parameter, the symbol of the parameter, the English abbreviation of the parameter, etc., for example, the transmission delay included in the business requirement parameter The identifier of RTT may be RTT, the identifier of packet loss rate may be ρ, the identifier of congestion window may be CWND, and the identifier of network bandwidth may be BW, etc., which are not specifically limited in this embodiment of the present invention.

For example, the service identifier of the service currently provided by the application layer is ID1. Based on the service identifier ID1, the transport service layer obtains the corresponding parameter identifiers as RTT and ρ, the transmission service layer identifies RTT and ρ based on this parameter, obtains the parameter corresponding to the transmission delay RTT from the service requirement parameter as 50ms, and the parameter corresponding to the packet loss rate ρ is 0.04%, and the transmission service layer sets the transmission delay RTT 50ms and The packet loss rate ρ0.04% is determined as the threshold parameter.

Table 1

It should be noted that, in the embodiment of the present invention, only the corresponding relationship between the service identifier and the parameter identifier shown in the above Table 1 is used as an example for illustration, and the above Table 1 does not limit the embodiment of the present invention.

For example, if the service is a video-on-demand service, the transport service layer receives the service requirement parameters sent by the application layer, including transmission delay, packet loss rate, congestion window at the sending end, maximum transmission unit, and throughput rate, etc. Among the parameters, the obtained threshold parameters are transmission delay and packet loss rate, and the transmission delay is 50ms, and the packet loss rate is 0.04%. Based on the transmission delay of 50ms and packet loss rate of 0.04%, the transmission service layer registers with the relevant layer Key event, after the key event registration is successful, if the current transmission delay of the relevant layer during the business data transmission process is 60ms, the current transmission delay of 60ms is greater than the transmission delay of 50ms in the threshold parameter, so the relevant layer will transfer the current transmission status The information is reported to the transport business layer.

(2) The transmission service layer sends the reporting period to the relevant layer, so that the relevant layer reports the transmission status information to the transmission service layer every reporting period.

In order to ensure that the business is in a normal state, that is, to ensure that the business data transmission of the transport layer is carried out normally, the transport service layer can also periodically obtain the transmission status information of the relevant layer, so that the business data transmission of the transport layer can be real-time It can be monitored in a timely manner without imposing an excessive burden on the relevant layers. Therefore, the transmission service layer may send the reporting period to the relevant layer, so that the relevant layer reports the transmission status information to the transmission service layer every the reporting period.

It should be noted that the reporting period may be set in advance, for example, the reporting period is 5 minutes, 10 minutes, 30 minutes, etc., which is not specifically limited in this embodiment of the present invention.

For example, the reporting period is 10 minutes, and the transmission service layer sends the reporting period of 10 minutes to the relevant layer, so that the relevant layer sends the transmission status information to the transmission service layer every 10 minutes.

(3) When the first transmission connection of the relevant layer to transmit service data is disconnected, report the transmission state information to the transmission service layer.

Before the business data is transmitted, the transport service layer needs to establish a first transmission connection between the relevant layer and the server, and perform business data transmission through the first transmission connection, when the relevant layer performs the first transmission connection of business data transmission When disconnected, the application layer cannot obtain the data required by the current service provided, which will affect the normal operation of the service. Therefore, when the first transmission connection of the relevant layer for business data transmission is disconnected, the relevant layer can transfer The business layer reports the transmission status information.

It should be noted that, in the embodiment of the present invention, since the relevant layer includes at least the transport layer, of course, in order to further improve the efficiency of service data transmission, the relevant layer may also include the network layer, therefore, the transport service layer can not only pass the above three The method obtains the state information of the transport layer. Of course, the transport service layer can also obtain the state information of the transport layer and the state information of the network layer at the same time through the above three methods, that is, the transport service layer can at least obtain the state information of the transport layer. The embodiment of the present invention This is not specifically limited.

Step 302: Obtain transmission delay and packet loss rate from the transmission status information, and determine the transmission status of the relevant layer based on the transmission delay and packet loss rate.

When the transmission service layer receives the transmission status information, in order to determine the transmission status of the current business data transmission, and adjust the process of business data transmission in a timely manner based on the transmission status, so as to ensure the normal progress of business data transmission, therefore, the The transmission service layer can obtain the transmission delay and packet loss rate from the transmission status information, and determine the transmission status of the relevant layer based on the transmission delay and packet loss rate.

Wherein, the operation of the transmission service layer to determine the transmission state of the relevant layer based on the transmission delay and packet loss rate may be: when the transmission delay is greater than or equal to the first specified delay and the packet loss rate is greater than or equal to the first specified When the packet loss rate is lower than or equal to the second specified packet loss rate, determine that the transmission state of the relevant layer is an overload state; when the transmission delay is less than or equal to the second specified delay and the packet loss rate is less than or equal to the second specified packet loss rate, determine that the transmission state of the relevant layer is light load state; when the transmission delay is less than the first specified delay and greater than the second specified delay, or the packet loss rate is less than the first specified packet loss rate and greater than the second specified packet loss rate, determine that the transmission status of the relevant layer is normal state.

It should be noted that the first specified delay, the second specified delay, the first specified packet loss rate, and the second specified packet loss rate can all be set in advance, and the first specified delay is greater than the second specified delay, and the first specified The specified packet loss rate is greater than the second specified packet loss rate. For example, the first specified delay is 50ms, 55ms, etc., the second specified delay is 10ms, 20ms, etc., and the first specified packet loss rate is 0.04%, 0.05%, etc., The second specified packet loss rate is 0.01%, etc., which is not specifically limited in this embodiment of the present invention.

For example, the first specified delay is 50ms, the second specified delay is 10ms, the first specified packet loss rate is 0.04%, and the second specified packet loss rate is 0.01%. The transmission service layer obtains from the transmission status information The transmission delay is 60ms, and the packet loss rate is 0.06%. Since the transmission delay of 60ms is greater than the first specified delay of 50ms, and the packet loss rate of 0.06% is greater than the first specified packet loss rate of 0.04%, the transmission service The layer determines that the transmission state of the associated layer is an overload state.

It should be noted that since the transport service layer can obtain at least the transport layer state information, when the transport state information includes the transport layer state information, the transport service layer can obtain the transmission delay and loss of the transport layer from the transport layer state information. Packet rate, and based on the transmission delay and packet loss rate of the transport layer, determine the transmission status of the transport layer, and when the transmission status information includes not only the status information of the transport layer, but also the status information of the network layer, the transport service layer can not only In the layer status information, the transmission delay and packet loss rate of the transport layer are obtained, and the transmission status of the transport layer is determined based on the transmission delay and packet loss rate of the transport layer. At the same time, the network layer can also be obtained from the network layer status information. The transmission delay and packet loss rate of the network layer, and based on the transmission delay and packet loss rate of the network layer, determine the transmission status of the network layer.

Step 303: Determine the service type to which the first service belongs and the network type of the network to which the network layer is currently connected.

In order to make more accurate and targeted adjustments to the business data transmission process, to ensure the smooth progress of business data transmission, to improve the speed and quality of business data transmission, and to keep the first business currently provided by the application layer in a normal state, The transport service layer needs to determine the service type to which the first service belongs and the network type of the network to which the network layer is currently connected.

Wherein, the operation of the transport service layer to determine the service type to which the first service belongs may be as follows: the transport service layer obtains the service identifier of the first service, and based on the service identifier, obtains the corresponding relationship between the stored service identifier and the service type , acquire the corresponding service type, and determine the acquired service type as the service type to which the service currently provided by the application layer belongs.

For example, the transport service layer acquires the service identifier of the first service as ID1, and the transport service layer obtains the corresponding service type as type from the correspondence between the service identifier and service type shown in Table 2 below based on the service identifier ID1. 1, and determine the type 1 as the service type to which the first service belongs.

Table 2

It should be noted that, in the embodiment of the present invention, only the corresponding relationship between the service identifier and the service type shown in the above Table 2 is used as an example for illustration, and the above Table 2 does not limit the embodiment of the present invention.

Wherein, when the transport service layer determines the network type of the network currently connected to the network layer, the transport service layer can not only directly determine the network type of the network currently connected to the network layer based on the network currently connected to the terminal, but also can select from multiple consecutive Multiple consecutive transmission delays and packet loss rates are obtained from the received transmission status information, and based on the multiple continuous transmission delays and packet loss rates, the network type of the network currently connected to the network layer is determined.

The operation of the transmission service layer to determine the network type of the network currently connected to the network layer based on the multiple continuous transmission delays and packet loss rates can be as follows: the transmission service layer obtains the transmission time from the multiple continuous transmission delays The maximum delay value and the minimum transmission delay value, and based on the maximum transmission delay value and the minimum transmission delay value, determine the delay variation of the multiple continuous transmission delays, and from the multiple continuous packet loss rates, Obtain the maximum value of the packet loss rate and the minimum value of the packet loss rate, and based on the maximum value of the packet loss rate and the minimum value of the packet loss rate, determine the variation of the packet loss rate of the multiple consecutive packet loss rates, when the multiple continuous transmission delays When all are greater than the first threshold, the delay variation is less than the second threshold and the packet loss rate variation is less than the third threshold, it is determined that the network type of the network currently connected to the network layer is a wireless network; otherwise, it is determined that the network layer is currently connected The network type of the connected network is a non-wireless network, that is, when the multiple continuous transmission delays obtained are always large and packet loss occurs occasionally, the transmission service layer can determine the network type of the network currently connected to the network layer is a wireless network, otherwise, determine that the network type of the network currently connected to the network layer is a non-wireless network.

What needs to be said is that the first threshold, the second threshold and the third threshold can be set in advance, for example, the first threshold is 30ms, 35ms, the second threshold is 5ms, 7ms, the third threshold is 0.015%, 0.002%, etc., This embodiment of the present invention does not specifically limit it.

In addition, the transport service layer can not only determine the network type of the network currently connected to the network layer based on the multiple continuous transmission delays and packet loss rates, of course, in practical applications, the transport service layer can also determine the network type based on the multiple continuous Transmission delay, packet loss rate, and other continuous parameters determine the network type of the network currently connected to the network layer, which is not specifically limited in the embodiment of the present invention.

Step 304: Determine a second transmission protocol and a second transmission parameter based on the transmission delay, packet loss rate, transmission status, the service type and the network type.

In order to ensure that the first service currently provided by the application layer can be in a normal state, and to avoid transmission congestion and data packet loss during service data transmission, the transmission service layer needs to be based on the transmission delay, packet loss rate, transmission The state, the service type and the network type determine the second transmission and the second transmission protocol parameters. And based on the transmission delay, packet loss rate, transmission status, the service type and the network type, the operation of determining the second transmission and the second transmission protocol parameters can be: based on the service type and the network type, determining the second transmission A protocol: determining a second transmission parameter based on the transmission delay, packet loss rate and transmission status.

Wherein, when the transmission service layer determines the second transmission protocol based on the service type and the network type, the transmission service layer may, based on the service type and the network type, learn from the stored correspondence between the service type, the network type, and the transmission protocol In the relationship, the corresponding transmission protocol is obtained, and the obtained transmission protocol is determined as the second transmission protocol.

For example, if the network type is a wireless network, the transmission service layer can obtain the corresponding transmission service layer from the correspondence between the service type, network type and transmission protocol as shown in Table 3 below based on the service type being type 1 and wireless network. The protocol is protocol 1, and the transport service layer determines the protocol 1 as the second transport protocol.

table 3

It should be noted that, in the embodiment of the present invention, only the corresponding relationship between the service type, the network type and the transmission protocol shown in the above Table 3 is used as an example for illustration, and the above Table 3 does not limit the embodiment of the present invention.

Wherein, when the transmission service layer determines the second transmission parameter based on the transmission delay, packet loss rate and transmission state, if the transmission state is normal, the transmission service layer determines that the service data transmission is in the normal state, and can fully utilize The resources provided by the network layer and the transport layer will not cause congestion, data packet loss, etc., so that the transport service layer can directly determine the first transmission parameter as the second transmission parameter; if the transmission status is abnormal, That is, when the transmission state is overloaded or lightly loaded, the transmission parameters configured for the transmission layer are different for different transmission protocols, and the transmission protocol can be divided into reliable and reliable according to the reliability of business data transmission. Transmission protocol and unreliable transmission protocol, for example, TCP protocol is a typical reliable transmission protocol, and UDP protocol is a typical unreliable transmission protocol. Therefore, regarding whether the second transmission protocol is a reliable transmission protocol, the transmission service layer determines the second transmission parameter based on the transmission delay and the packet loss rate may include two situations, as described below.

In the first case, when the second transmission protocol is an unreliable transmission protocol, the transmission service layer determines the delay range to which the transmission delay belongs and the packet loss to which the packet loss rate belongs based on the transmission delay and the packet loss rate. rate range, and based on the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs, the corresponding relationship between the stored delay range, packet loss rate range and transmission parameters is obtained. A transmission parameter, and determining the acquired transmission parameter as a second transmission parameter.

Wherein, based on the transmission delay and packet loss rate, the operation of the transmission service layer to determine the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs may be: the transport service layer obtains the stored delay range , The correspondence between the packet loss rate range and the transmission parameters includes the delay range and the packet loss rate range, and multiple delay ranges and multiple packet loss rate ranges are obtained. For each time delay range in the multiple delay ranges Delay range, when the transmission delay is greater than the minimum value of the delay range and less than the maximum value of the delay range, the transmission service layer determines the delay range as the delay range to which the transmission delay belongs; similarly, For each packet loss rate range in the plurality of packet loss rate ranges, when the packet loss rate is greater than the minimum value of the packet loss rate range and smaller than the maximum value of the packet loss rate range, the transport service layer will drop the packet The rate range is determined as the packet loss rate range to which the packet loss rate belongs.

Further, when the transmission state is overloaded, the transmission service layer determines that there is congestion in the transmission of service data, accompanied by the phenomenon of data packet loss, and by adjusting the first transmission parameter, the congestion and data packet loss of the transmission layer can be alleviated phenomenon, to ensure that the services currently provided by the application layer can be in a normal state; if the transmission state is a light load state, the transmission service layer determines that there are fewer data packets transmitted during the business data transmission process, and cannot fully utilize the network layer and transmission The resource provided by the application layer can make the service currently provided by the application layer in a better state by adjusting the first transmission parameter, so as to improve the service quality of the service.

For example, the transmission status is overloaded, the transmission delay is 60ms, and the packet loss rate is 0.06%. The transmission service layer determines that the service data transmission process of the transport layer is congested and accompanied by data packet loss. In order to slow down The loss of data packets ensures that the services currently provided by the application layer can be in a normal state. Based on the transmission delay of 60ms and the packet loss rate of 0.06%, the transmission service layer determines that the delay range of the transmission delay of 60ms is (50, 65] , the packet loss rate range of 0.06% is (0.04%, 0.08%], so that the transmission service layer is based on the delay range (50, 65] and the packet loss rate range (0.04%, 0.08%], From the correspondence between the delay range, the packet loss rate range, and the transmission parameters shown in Table 4 below, the corresponding transmission parameter is obtained as parameter 2, and the parameter 2 is determined as the second transmission parameter.

Table 4

It should be noted that, in the embodiment of the present invention, only the corresponding relationship between the delay range, the packet loss rate range and the transmission parameters shown in the above Table 4 is used as an example for illustration, and the above Table 4 is not specific to the embodiment of the present invention. constituting a limit.

In the second case, when the second transmission protocol is a reliable transmission protocol, the transmission service layer determines the delay range to which the transmission delay belongs and the packet loss rate to which the packet loss rate belongs based on the transmission delay and the packet loss rate range, and based on the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs, the corresponding congestion algorithm, and the transmission service layer determines the second transmission parameter based on the congestion algorithm.

Wherein, the transmission service layer determines the delay range to which the transmission delay belongs and the packet loss rate range to which the packet loss rate belongs based on the transmission delay and the packet loss rate, which is similar to the first case above, and the embodiment of the present invention is here No longer.

In addition, when the transmission service layer determines the second transmission parameter based on the congestion algorithm, since different congestion algorithms correspond to different adjustment ratios, the transmission service layer can use the congestion algorithm stored based on the congestion algorithm and the adjustment ratio. In the corresponding relationship, the corresponding adjustment ratio is obtained, and the adjustment ratio is multiplied by the first transmission parameter to obtain the second transmission parameter.

For example, the second transmission protocol is a reliable transmission protocol. Based on the transmission delay of 60ms and the packet loss rate of 0.06%, the transmission service layer determines that the delay range of the transmission delay of 60ms is (50, 65], the packet loss rate The packet loss rate range of 0.06% is (0.04%, 0.08%], so the transmission service layer is based on the delay range (50, 65] and the packet loss rate range (0.04%, 0.08%], as shown in Table 5 below In the corresponding relationship between the delay range, the packet loss rate range and the congestion algorithm shown, the corresponding congestion algorithm is obtained as Algorithm 2, and the transmission service layer is based on this algorithm 2, from the congestion algorithm and the adjustment ratio shown in Table 6 below In the corresponding relationship between, the corresponding adjustment ratio is obtained as ratio 2, and based on the ratio 2, each parameter included in the first transmission parameter is multiplied by the ratio 2 for adjustment to obtain the second transmission parameter.

It should be noted that, in the embodiment of the present invention, only the corresponding relationship between the delay range, the packet loss rate range and the congestion algorithm shown in Table 5 above is used as an example for illustration, and the above Table 5 is not specific to the embodiment of the present invention. constituting a limit.

It should be noted that, in the embodiment of the present invention, only the correspondence between the congestion algorithm and the adjustment ratio shown in Table 6 is used as an example for illustration, and the above Table 6 does not limit the embodiment of the present invention.

Further, since the transmission status information can include not only the status information of the transport layer, but also the status information of the network layer, the transport service layer can not only obtain the second transmission and the second transmission based on the transport layer status information through the above steps 302-304. When the parameters of the second transmission protocol are used, the second transmission protocol and the second transmission protocol parameters can also be comprehensively determined based on the transmission layer state information and the network layer state information, so that the adjusted second transmission protocol and the second transmission parameters can be more accurate Accurate to ensure the smooth progress of business data transmission at the transport layer and improve the speed and quality of business data transmission.

That is, in the embodiment of the present invention, the transmission service layer determines the second transmission protocol and the second transmission protocol parameters include two methods: the first method, the transmission service layer determines the second transmission protocol and the second transmission protocol parameters based on the transport layer status information The second transmission protocol parameter; the second method, the transmission service layer determines the second transmission protocol and the second transmission protocol parameters based on the transmission layer status information and the network layer status information.

Step 305: Send the second transmission protocol and the second transmission parameters to the transport layer, so that the transport layer transmits the subsequent service data of the first service based on the second transmission protocol and the second transmission parameters.

When the transmission service layer determines the second transmission protocol and the second transmission parameters, the transmission service layer sends the second transmission protocol and the second transmission parameters to the transmission layer, so that the transmission layer performs the transmission based on the second transmission protocol and the second transmission parameters. Business data transmission, in order to realize the control of the business data transmission process, avoid congestion and data packet loss at the transport layer or network layer, and also enable business data transmission to make full use of resources at the transport layer and network layer to improve business data transmission. speed and quality, while ensuring that the services currently provided by the application layer are in a normal state.

Further, when the transport service layer sends the second transport protocol and the second transport parameters to the transport layer, so that the transport layer performs service data transmission based on the second transport protocol and the second transport parameters, in order to make the next service data The transmission can enter the normal state faster, so as to reduce the time for adjusting the transmission protocol and transmission parameters of the transmission layer. The transmission service layer can store the second transmission protocol and the second transmission parameters. When the transmission layer re-establishes the second transmission service data During the transmission connection, the transmission service layer may directly configure the transmission protocol and transmission parameters of the transmission layer as the second transmission protocol and the second transmission parameters.

For example, the second transmission protocol is the TCP protocol, and the second transmission parameters include parameters such as congestion window, maximum transmission unit, buffer, and transmission bandwidth, and the congestion window is 20kb/s, the maximum transmission unit is 110bit, the buffer is 3M, and the transmission The bandwidth is 5M/s, etc., and the transmission service layer stores the congestion window 20kb/s, maximum transmission unit 110bit, buffer 3M, transmission bandwidth 5M/s, etc. included in the second transmission protocol TCP protocol and the second transmission parameters, when the When the transport layer re-establishes the second transport connection for transporting business data, the transport service layer can directly configure the transport protocol of the transport layer as the TCP protocol, configure the congestion window included in the transport parameters as 20kb/s, and configure the maximum transmission unit as 110bit , The buffer configuration is 3M, the transmission bandwidth is configured as 5M/s, etc., so that the business data transmission can enter the normal state faster.
