The Data Over Cable Service Interface Specification (DOCSIS) protocol is a point-to-multipoint Data transmission protocol, and the downlink direction adopts a broadcast mode to transmit Data messages, and the main delay is physical modulation, interleaving, and the like of Data. The upstream direction uses a Coaxial Modem (CM) to request time slots (i.e., bandwidth), and the coaxial Modem termination system (Cable Modem Termination System, CMTS) allocates time slots within which the CM sends data to be transmitted. Data transmission in the upstream direction is shown in fig. 1, and as can be seen from fig. 1, before data is sent out from the CM end, the CM must first request bandwidth resources from the CMTS and wait for the CMTS to allocate the bandwidth resources before transmitting the data, which tends to cause delay in data transmission.

In this embodiment of the present application, the bandwidth request end may be a CM, and in other embodiments, the bandwidth request end may also be other devices for sending data to be transmitted in an uplink direction.
In the actual implementation process, S21 may be in a manner that after the bandwidth request end receives the data packet of the data to be transmitted sent by the third party, the bandwidth request end extracts the packet characteristics of the data packet, and determines the service flow matched with the packet characteristics based on the packet characteristics, the bandwidth size, the priority and other parameters of each service flow, and since each service flow has a unique identifier representing the identity of the service flow, the identifier of the service flow matched with the data to be transmitted is determined, so as to distribute the data to be transmitted to the service flow matched with the packet characteristics for transmission, where a tool adopted in classification may be a classifier in Docsis.
After determining the identification of the service flow corresponding to the message feature, step S22 is performed.
S22: the bandwidth requesting end sends a bandwidth request containing the identification of the service flow to the bandwidth distributing end.
In this embodiment, the bandwidth allocation end is a CMTS, and in other embodiments, the bandwidth allocation end may be other devices that can be used to allocate network bandwidth.
And under the condition that the bandwidth request end needs to transmit data to be transmitted by utilizing the service flow corresponding to the identification of the service flow, the bandwidth request end generates a bandwidth request based on the identification of the service flow and sends the bandwidth request to the bandwidth allocation end. Wherein the bandwidth request includes an identification of the service flow.

After receiving the bandwidth request, the bandwidth allocation terminal extracts the identifier of the service flow from the bandwidth request, determines whether the identifier of the service flow is the same as the predetermined identifier of the service flow needing bandwidth active allocation, and when determining that the identifier of the service flow is the same as the predetermined identifier of the service flow needing bandwidth active allocation, characterizes that the identifier of the service flow meets a first preset rule, otherwise, characterizes that the identifier of the service flow does not meet the first preset rule; when the bandwidth request terminal determines that the identifier of the service flow meets the first preset rule, based on the identifier of the service flow, the bandwidth size and the corresponding interval duration corresponding to the identifier of the service flow are searched out from the corresponding relation between the pre-established identifier and the bandwidth size and the interval duration.
As another embodiment, if the bandwidth request includes: the step of determining the bandwidth size and the corresponding interval duration corresponding to the identification of the service flow comprises the following steps:
the bandwidth allocation end extracts the bandwidth size of the service flow from the bandwidth request, determines that the bandwidth size of the service flow is the bandwidth size corresponding to the identification of the service flow when the identification of the service flow meets a first preset rule, and takes the predetermined interval duration as the interval duration corresponding to the identification of the service flow.
Wherein, as an implementation manner, the step of determining whether the identifier of the service flow meets the first preset rule includes: determining whether the identifier of the service flow comprises preset characters for representing that bandwidth is required to be actively allocated, if the identifier of the service flow comprises the preset characters, representing that the identifier of the service flow meets the first preset rule, otherwise, representing that the identifier of the service flow does not meet the first preset rule. The preset characters can be A,5, F and the like, and are set according to the requirements of users.
The step of establishing the corresponding relation comprises the following steps: a1, A2 and A3.
A1: the bandwidth request end sends a configuration request which characterizes that bandwidth allocation parameters need to be configured for the service flow to the bandwidth allocation end; wherein, the configuration request includes: the size of the bandwidth required by the service flow and the identity of the service flow.
And the bandwidth request end generates a configuration request based on the bandwidth size required by the service flow and the identification of the service flow, and sends the configuration request to the bandwidth allocation end.
As an embodiment, the configuration request further includes: the bandwidth request end actively allocates the interval duration of the bandwidth.
The interval duration can be set according to user requirements.
A2: and the bandwidth allocation terminal receives the configuration request.
A3: when the bandwidth allocation terminal determines that the identifier of the service flow meets the first preset rule, based on a predetermined interval duration and the required bandwidth size, establishing a corresponding relation between the identifier of the service flow and the required bandwidth size and the predetermined interval duration; the required bandwidth is the corresponding bandwidth, and the predetermined interval duration is the corresponding interval duration.
After receiving the configuration request, the bandwidth allocation end extracts the identifier of the service flow and the required bandwidth from the configuration request, and determines whether the identifier of the service flow meets the first preset rule, where the manner of determining whether the identifier of the service flow meets the first preset rule is referred to as step S24, so that details are not repeated herein, when it is determined that the identifier of the service flow meets the first preset rule, based on a predetermined interval duration and the required bandwidth, a corresponding relationship between the identifier of the service flow and the required bandwidth and the predetermined interval duration is established.
As an implementation manner, when the configuration request includes the interval duration, the interval duration is extracted from the configuration request, and when it is determined that the identifier of the service flow meets the first preset rule, based on the interval duration and the required bandwidth size, a corresponding relationship between the identifier of the service flow and the required bandwidth size and the interval duration is established. Wherein the interval duration is the predetermined interval duration in step A3.
After determining the corresponding bandwidth size and the corresponding interval duration, the bandwidth allocation end executes step S25.
S25: and the bandwidth allocation terminal allocates the bandwidth matched with the corresponding bandwidth size for the service stream from the current moment at intervals of the corresponding interval duration based on the corresponding bandwidth size and the corresponding interval duration.
The bandwidth allocation terminal determines the bandwidth matched with the corresponding bandwidth at the current moment, wherein the size of the matched bandwidth can be the same as or basically the same as the corresponding bandwidth, then information comprising the identification of the service flow and the matched bandwidth is sent to the bandwidth request terminal, so that the bandwidth request terminal can accurately determine that the matched bandwidth is allocated for the service flow to transmit data to be transmitted at the current moment based on the information, then the bandwidth matched with the corresponding bandwidth is redetermined at preset interval time intervals, and the redetermined matched bandwidth and the identification of the service flow are sent to the bandwidth request terminal, wherein the redetermined matched bandwidth can be the same as or different from each other.
It is mentioned that each time a matching bandwidth is determined, it is likely that the bandwidth is in an idle state.
After the bandwidth allocation end sends the matched bandwidth and the identification of the service flow to the bandwidth request end, step S26 is performed.
S26: and the bandwidth request terminal receives the matched bandwidth and the identification of the service flow.
And the bandwidth request terminal receives the matched bandwidth and the identification of the service flow sent by the bandwidth allocation terminal in real time.
S27: and the bandwidth request end transmits the data to be transmitted on the service stream based on the matched bandwidth.
And the bandwidth request end uses the matched bandwidth to transmit the data to be transmitted on the service flow corresponding to the identification of the service flow.
In the implementation process, after the bandwidth request sent by the bandwidth request end on the service flow is received, when the identification of the service flow is determined to meet a first preset rule, the bandwidth size and the corresponding interval duration corresponding to the identification of the service flow are determined, then the bandwidth matched with the corresponding bandwidth size is continuously allocated to the service flow at intervals of the corresponding interval duration from the current moment, the bandwidth request end does not need to send the bandwidth request to the bandwidth allocation end each time before the data are transmitted by the service flow, the bandwidth allocation end does not need to allocate the bandwidth to the service flow each time after the bandwidth request is received, and network delay of data transmission caused by bandwidth allocation is reduced.
If no data transmission is performed on the service flow, bandwidth is continuously allocated to the service flow, which results in waste of bandwidth resources, and therefore, as an embodiment, the following steps are included in S25: b1 and B2.

And the bandwidth request end starts timing when determining that the flow is zero, and stops determining and distributing the bandwidth for the service flow when the duration time of the zero flow reaches the preset duration time, so that the waste of bandwidth resources is avoided. It can be appreciated that when the duration does not reach the preset duration, bandwidth is continuously and actively allocated to the service flow.
When the traffic of the data transmitted on the service flow is smaller, if a larger bandwidth is allocated to the service flow, the bandwidth resource is wasted, and when the traffic of the data transmitted on the service flow is larger, if a smaller bandwidth is allocated to the service flow, the duration of the data transmission is longer, so as an embodiment, after S25, the method further includes the steps of: c1, C2 and C3.

The first preset value and the second preset value are set according to actual requirements. The first preset value and the second preset value are positive numbers.
When the traffic size is not matched with the bandwidth size allocated for the service flow at the current moment, re-determining a new bandwidth size matched with the traffic size; it will be appreciated that the bandwidth size is not redetermined when a match is determined.
And C3: and when the time length from the last time of allocating the bandwidth to the service flow reaches the corresponding interval time length, allocating the bandwidth matched with the new bandwidth size to the service flow.
And starting to time from the last time of distributing the bandwidth to the service flow, and distributing the bandwidth matched with the new bandwidth size to the service flow when the time duration reaches the corresponding interval duration.

Wherein the step of determining a first bandwidth size corresponding to the identification of the service flow comprises:
and based on the identification of the service flow, searching the first bandwidth size corresponding to the identification of the service flow from a first corresponding relation between the pre-established identification and the bandwidth size.
The step of establishing the first corresponding relation comprises the following steps: d1, D2 and D3.
