Description
Technical Field
The embodiment of the application relates to the field of communication transmission, in particular to a load processing method, gateway equipment and system for cross-equipment link aggregation.
Background
Generally, message transmission between a switch system and nodes upstream and downstream is carried out by the switches forming the system through cross-device link aggregation. The upstream and downstream load balancing proportion of the cross-device link aggregation switch system is passively determined by a load balancing algorithm of upstream or downstream network devices, and the switch only performs passive message forwarding; or a Software Defined Network (SDN) is configured, a load balancing proportion of upstream and downstream is dynamically calculated through the SDN Network, and the load balancing proportion is sent to upstream and downstream Network devices, so that an effect of balancing Network traffic is achieved.
However, when the SDN network is not used, the switch cannot feed back or participate in adjusting the traffic sent to the switch, all decision-making weights depend on the source of the data traffic, and the switch only passively forwards the traffic; in the SDN network, calculation can be performed according to the condition of link bandwidth to achieve a balanced state of upstream and downstream traffic, but configuration of the SDN and an SDN controller needs to be additionally performed, so that greater investment exists for networking, and network operation cost is increased. That is, if the configuration is not performed using the SDN controller, in the non-SDN network, the proportion of load balancing cannot be determined according to the specific bandwidth situation of the uplink and downlink of the cross-device link aggregation switch system. Therefore, in network application, if bandwidth imbalance occurs in the downlink, the traffic of the uplink will not change accordingly, and the problems of packet loss or insufficient bandwidth utilization rate due to insufficient bandwidth are easily caused.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, the terms "comprise" and "have", as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a system, product or apparatus that comprises a list of elements or components is not limited to only those elements or components but may alternatively include other elements or components not expressly listed or inherent to such product or apparatus. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.
One embodiment of the invention relates to a load processing method for cross-device link aggregation, which is applied to a gateway device in a cross-device link aggregation system, wherein the gateway device is used for carrying out data transmission with a cross-device link aggregation switch system in the cross-device link aggregation system. The specific flow is shown in figure 1.
and step 102, adjusting the load proportion of data transmission to each switch in the cross-device link aggregation switch system according to the load information.
In this embodiment, the gateway device receives the load information fed back by the switch system, and adjusts the data transmission load proportion to the switch system according to the load information, so that the transmission bandwidth of the entire network can be allocated in proportion to obtain maximum utilization. By using the method, the bandwidth utilization rate of the network is improved, network abnormity with insufficient bandwidth is reduced, the reliability and maintainability of the network are improved, and the networking cost is saved.
The following describes implementation details of the load processing method for cross-device link aggregation according to this embodiment in a specific manner, and the following description is only provided for facilitating understanding of the implementation details and is not necessary for implementing this embodiment.
In step 101, load information fed back by the cross-device link aggregation switch system is received in real time, where the load information includes, for example, a data bandwidth that can be carried in the cross-device link aggregation switch system, a data transmission delay in the cross-device link aggregation switch system, a type of data transmission that can be carried in the cross-device link aggregation switch system, and the like.
In one example, the load information is, for example, the downstream transmission bandwidth of each switch or the proportion of the downstream load of each switch. That is to say, the cross-device link aggregation switch system feeds back information of data traffic sent downwards, which can be borne by each switch in the system, to the gateway device, so that the gateway device can adjust a relevant data interaction process according to the information.
In one example, the transmission bandwidth is an available bandwidth obtained by real-time detection according to user configuration after each switch respectively obtains the user configuration corresponding to each switch; the user configuration includes information of the transport ports that need to be used in each switch, e.g. which transport ports need to be used in all transport ports. That is, each switch respectively obtains information of transmission ports which need to be used and are configured by each user, for example, M ports are total, N ports need to be used at this time, N is less than or equal to M, that is, a range of the ports which need to be used is firstly defined; and further detecting available ports in real time in the N ports to be used, and obtaining available bandwidth. It can be understood that if all ports need to be used, that is, the configuration information does not need to be acquired, the transmission port can be directly detected to obtain the available bandwidth.
In one example, the downlink load ratio is calculated by any one of the switches according to the downlink transmission bandwidth thereof and the acquired downlink transmission bandwidths transmitted by the other switches. For example, the switches are at least a first switch and a second switch, the first switch acquires downlink transmission bandwidth of the first switch and transmits the downlink transmission bandwidth to the second switch, the second switch acquires the downlink transmission bandwidth of the second switch and simultaneously receives the downlink transmission bandwidth of the first switch transmitted by the first switch, and the second switch can calculate downlink load proportion of the first switch and the second switch through the two groups of downlink transmission bandwidths and upload the proportion data to the gateway device.
In one example, receiving load information fed back across a device link aggregation switch system includes: load information in a protocol message inserted into a cross-device link aggregation switch system is received. That is, when the cross-device link aggregation switch system feeds back load information to the gateway device, the load information is inserted into a message for transmission, for example, a downlink transmission bandwidth of each switch or a proportion of a downlink load of each switch is inserted into the message and sent to the gateway device; further, the downlink transmission bandwidth of each switch or the proportion of the downlink load of each switch is inserted into a private protocol message, or inserted into a public protocol message provided with a private field for data transmission.
In this step, the gateway device receives load information fed back by the cross device link aggregation switch system, where the load information can reflect the carrying capacity of data transmission in the cross device link aggregation switch system or the change of the carrying capacity of data transmission, so that the gateway device can adjust the load information.
In step 102, a load ratio of data transmission to each switch in the cross-device link aggregation switch system is adjusted according to the load information.
In one example, after receiving load information fed back by the cross-device link aggregation switch system, the gateway device adjusts the transmission ratio according to the load information, so that the resource utilization rate of the cross-device link aggregation switch system can be optimal. For example, when a downlink load proportion transmitted by the cross-device link aggregation switch system is received, adjustment is directly performed according to the proportion value, if a downlink transmission bandwidth of each switch transmitted by the cross-device link aggregation switch system is received, the downlink load proportion is calculated according to each downlink transmission bandwidth, and the data transmission proportion to the cross-device link aggregation switch system is adjusted according to the calculated downlink load proportion.
In one example, data transmission between the gateway device and the cross-device link aggregation switch system is performed according to a private protocol, or is performed according to a public protocol provided with a private field; data transmission between the switch system and the gateway device is performed according to a private protocol or a public protocol provided with a private field without additionally configuring an SDN network.
Specifically, when the gateway device and the cross-device link aggregation switch system perform information interaction, the transmission is performed according to a private protocol or a public protocol with private fields, the unification of the specifications of each electronic device in the gateway device and the cross-device link aggregation switch system is not required to be limited, an SDN network or an SDN device is not required to be additionally arranged, and the gateway device and the cross-device link aggregation switch system with different specifications can realize data transmission.
In addition, when load information changes, for example, a link failure occurs or a new aggregation link is added, the cross-device link aggregation switch system uploads the changed condition or the changed condition to the gateway device in time for the gateway device to adjust in time.
In the embodiment of the application, the bandwidth ratio value of each switch forming the system on the downlink aggregation group is calculated on the switches of the equipment link aggregation switch system by firstly collecting the downlink aggregation configuration information of the equipment link aggregation switch system, inquiring and judging the number and the bandwidth of the available links in the downlink according to the configuration information. Since the switch device of the device Link Aggregation switch system has already obtained the bandwidth ratio value of the downlink Aggregation group of each switch at present, further, the bandwidth ratio value may be transmitted to the upstream gateway device through an interaction Protocol between the device Link Aggregation switch system and the uplink device, and the transmission manner may be transmitted through a Link Aggregation Control Protocol (LACP) provided with a private field, or may be transmitted through other custom protocols or messages. After receiving the bandwidth proportional value, the upstream gateway device may adjust a factor of its load balancing algorithm according to the proportional value, so that when sending its traffic to the device link aggregation switch system, the upstream gateway device better conforms to the link bandwidth condition of the device link aggregation switch system to the downlink server device when load balancing to each switch of the device link aggregation switch system. Through the processing, it can be seen that the link bandwidth condition of the connection between the downlink of the device link aggregation switch system and the server can be transmitted to the gateway device through the existing protocol or other self-defined protocols or messages, and the gateway device can consider the ratio as a factor influencing the load balancing algorithm of the gateway device, so that when the traffic is sent to the device link aggregation switch system, the bandwidth proportional relation of the downlink of the device link aggregation switch system can be better met. This achieves the effect of maximizing the proportional utilization of the bandwidth of the entire network system.
In the implementation mode of the application, an SDN network does not need to be configured additionally, and data transmission between a switch system and gateway equipment is executed according to a private protocol or a public protocol with a private field; on the basis, the gateway equipment receives the load information fed back by the switch system, and adjusts the data transmission load proportion to the switch system according to the load information, so that the transmission bandwidth of the whole network can be distributed according to the proportion, and the maximum utilization is achieved. By using the method, the bandwidth utilization rate of the network is improved, network abnormity with insufficient bandwidth is reduced, the reliability and maintainability of the network are improved, and the networking cost is saved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
One embodiment of the present invention relates to a gateway device, where the gateway device is located in a cross-device link aggregation system, and the gateway device is configured to perform data transmission with a cross-device link aggregation switch system in the cross-device link aggregation system, and as shown in fig. 2, the gateway device specifically includes:
a receiving module 201, configured to receive load information fed back by a cross-device link aggregation switch system in real time;
an adjusting module 202, configured to adjust a load ratio of data transmission to each switch in the cross-device link aggregation switch system according to the load information.
In the receiving module 201, load information fed back by the cross-device link aggregation switch system is received, for example, load information in an insertion protocol message of the cross-device link aggregation switch system is received.
Wherein the load information includes: the downlink transmission bandwidth of each switch or the proportion of the downlink load of each switch.
In an example, the transmission bandwidth is an available bandwidth obtained by real-time detection according to the user configuration after the user configuration corresponding to each switch is respectively obtained by each switch; the user configuration includes information of the transmission ports to be used in the switches.
In an example, the downlink load ratio is calculated by any one of the switches according to the downlink transmission bandwidth thereof and the obtained downlink transmission bandwidths transmitted by the other switches.
In one example, data transmission between the gateway device and the cross-device link aggregation switch system is performed according to a private protocol, or is performed according to a public protocol provided with a private field.
It should be understood that this embodiment is a system example corresponding to the above embodiment, and that this embodiment may be implemented in cooperation with the above embodiment. The related technical details mentioned in the above embodiments are still valid in this embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related technical details mentioned in the present embodiment can also be applied to the above embodiments.
It should be noted that each module referred to in this embodiment is a logical module, and in practical applications, one logical unit may be one physical unit, may be a part of one physical unit, and may be implemented by a combination of multiple physical units. In addition, in order to highlight the innovative part of the present invention, a unit which is less closely related to solving the technical problem proposed by the present invention is not introduced in the present embodiment, but it does not indicate that no other unit exists in the present embodiment.
One embodiment of the present invention relates to a load processing system for cross-device link aggregation, which includes a gateway device, a cross-device link aggregation switch system communicatively connected to the gateway device, and a server communicatively connected to the cross-device link aggregation switch system, as shown in fig. 3.
The gateway device 301 is configured to receive load information fed back by the cross-device link aggregation switch system in real time; adjusting the load proportion of data transmission to each switch in the cross-device link aggregation switch system according to the load information;
the cross-device link aggregation switch system 302 includes at least two switches, and is configured to perform data transmission to the gateway device and the server, and feed back load information fed back by the cross-device link aggregation switch system to the gateway device, so that the gateway device adjusts a load ratio of data transmission to each switch in the cross-device link aggregation switch system;
and the server 303 is configured to receive and process the message data sent by the cross-device link aggregation switch system.
It is to be understood that the gateway device according to this embodiment corresponds to the above-described embodiment, and this embodiment can be implemented in cooperation with the above-described embodiment. The related technical details mentioned in the above embodiments are still valid in this embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related-art details mentioned in the present embodiment can also be applied to the above-described embodiments.
Specifically, first, the cross-device link aggregation switch system collects the proportion of the downstream load: the method comprises the steps that a main switch and a standby switch of a cross-equipment link aggregation switch system respectively obtain link configurations forming a link aggregation group from a downlink link aggregation group; according to the configuration, the states of the links are respectively obtained, and the links which cannot normally work are removed; the statistical relationship of the available link bandwidth ratios in the downlink aggregation groups of two switch devices is calculated on a certain switch to form data (for example, if the data is aggregated at a master switch, the master switch obtains the bandwidth ratio of the downlink aggregation link group on the two switches).
Secondly, the cross-device link aggregation switch system transmits the proportion of the downlink load to the upstream gateway device: the method comprises the steps that a switch which obtains the proportion of a downlink load in an equipment link aggregation switch system inserts data into a protocol message; the switch transmits the ratio data to the upstream gateway equipment through a message (such as LACP provided with a private field or a custom protocol or a message); after receiving the message, the gateway device correspondingly adjusts the load proportion of the aggregation link group sent to the device link aggregation switch system by the gateway device according to the data, so that the flow sent to the device link aggregation switch system is more in line with the condition of the downlink bandwidth proportion.
In the case where the downlink condition changes, for example: switches of the system of aggregation switches across device links sense that a downlink has changed (a link failure has occurred or a new aggregation link has been added); and triggering the steps again, transmitting the latest data to the upstream gateway equipment, and adjusting the load proportion again by the gateway equipment.
In this embodiment, the proportional relationship between the downlink loads of the respective links of the downlink aggregation groups of the two switches in the system can be determined directly from the configuration information and the downlink states, and the ratio result can be calculated at one switch. The switch which calculates the ratio result sends the ratio result to the upstream gateway equipment through a public protocol or other self-defined protocols or messages which are provided with private fields, and the gateway equipment adjusts the load balancing algorithm of the gateway equipment according to the ratio, so that the flow sent to the equipment link aggregation switch system by the gateway equipment is more in line with the proportional relation of the downlink flow of the system. When the state of the down link changes, the gateway device can immediately sense the change and adjust the change accordingly. The whole network can achieve the effect of dynamic balanced adjustment under the state that the SDN controller is not deployed.
For ease of understanding, a specific implementation will be described in detail, as shown in fig. 4;
for example, the switches a and B form a set of cross-device link aggregation switch system, where a is a master device, where a port A1 (port 1G) A2 (port 1G) of the switch a and a port B1 (port 10G) of the switch B form a cross-device aggregation link, and are connected to the server C. The uplink A3 (port 40G) of switch a and the uplink B3 (port 40G) of switch B are connected to the gateway G device, respectively.
The switch B calculates the bandwidth proportional relation to the server C; the ports forming link aggregation are known to be A1A2 and B1 on the switches A and B; checking the states of A1A2 and B1, finding that the states are both normally available, and acquiring bandwidth values of the states, wherein A1 is 1G, A2 is 1G, and B1 is 10G, so that the total of 2G is arranged on the side of the device A, and 10G is arranged on the side of the device B; the B device sends the bandwidth information to the main device A, and the main device A calculates the downlink load proportion of the AB device downlink connection server in the downlink aggregation group to be 1:5.
The switch A sends the proportion of the downlink load to the gateway device G; the switch A fills the data of the proportion 1:5 of the downlink load of the AB equipment into the private field of the user information of the LACP message; interacting with gateway equipment G through the LACP message, wherein the proportion information of the downlink load transmitted by the switch A received by the G equipment is 1:5; the gateway G equipment adjusts the load balance factor of the gateway G equipment, and controls the ratio of the data sent to A3 and the data sent to B3 at the gateway G side to be 1:5.
An A1 port of the switch A is abnormal; the A1 port of the switch A is abnormal; the switch a triggers bandwidth recalculation in the example 1, and because the port A1 is abnormal, only A2 remains in the device a and the downlink connection link, the proportion of the downlink load of the AB switch at this time becomes 1; a transmits the latest data to a gateway device G through a message, the gateway G device adjusts the load balancing factor of itself, and the ratio of the data sent to A3 and the data sent to B3 at the gateway G side is controlled to be 1.
It can be understood that, in a general use process, the cross-device link aggregation switch system feeds back load information of the data transmission link with the downstream server to the upstream gateway device, but can also feed back load information of the data transmission link with the upstream gateway device to the downstream server for load adjustment of the downstream server when necessary.
Compared with a common cross-device link aggregation standby load balancing method, the cross-device link aggregation switch system can transmit the proportion of the downlink load of the whole networking without adding SDN controller equipment through the processing of the technical means, and then adjust the load balancing algorithm of the flow, and when the link is abnormal, the load balancing algorithm can also be adjusted accordingly. And the transmission mode can directly adopt the existing protocol or the custom protocol or the message transmission, and the cost is extremely low. The method can ensure that the flow of the whole network dynamically changes along with the change of the requirement of the link, ensures that the bandwidth of the network is utilized to the maximum extent, improves the bandwidth utilization rate of the network, reduces the network abnormity with insufficient bandwidth, improves the reliability and maintainability of the network and saves the networking cost.
One embodiment of the invention relates to a gateway device, as shown in fig. 5, comprising at least one processor 401; and the number of the first and second groups,
a memory 402 communicatively coupled to the at least one processor; wherein,
the memory stores instructions executable by the at least one processor to enable the at least one processor to perform the load handling method of cross device link aggregation described above.
