All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Considering that, when network traffic is equally divided and then forwarded, if the equally divided traffic is greater than the maximum bandwidth of a certain member port, a part of the traffic will be lost, embodiments of the present invention provide a traffic forwarding method, apparatus, network device, and computer-readable storage medium, which alleviate the problem of part of the traffic lost due to the equally divided traffic and reduce the problem of packet loss of the forwarded traffic of the member port due to the board card performance difference.
For convenience of understanding, first, a detailed description is given to a traffic forwarding method provided in an embodiment of the present invention, referring to a flow diagram of a traffic forwarding method shown in fig. 1, where the method mainly includes the following steps S102 to S106:
step S102: when the network equipment receives the network flow, judging whether the average flow of the network flow exceeds the maximum bandwidth of a certain member port in the aggregation group.
Network traffic is received by a network device through a network device interface, which generally refers to a physical form visible externally on the network device, such as 10/100/1000M electrical interface, 1GE/10GE/100GE optical interface, and so on. The average traffic of the network traffic is the traffic distributed to each member port when the network traffic is uniformly forwarded, for example, the aggregation group includes 4 physical interfaces, each physical interface may also be referred to as a member port of the aggregation group, the maximum allowed bandwidth of each member port is 20G, 10G, 20G, when the network traffic is 60Gbps, 15G should be distributed to each physical port to completely forward the network traffic when the network traffic is average, at this time, there is an aggregation group member port where the average traffic of 15G is greater than the maximum allowed bandwidth of 10G, and in order to not cause traffic loss, the following step S104 is adopted to perform weight distribution.
Step S104: if so, a target weight is assigned based on the bandwidth proportion of each member port in the aggregation group.
In an embodiment, if there is an average traffic larger than the maximum bandwidth allowed by the aggregation group member port, then performing the average retransmission of the network traffic may cause loss of part of the traffic, and in order to avoid the traffic loss problem caused by the average traffic, a target weight is allocated based on the bandwidth proportion of each member port in the aggregation group. The hash value can be filled in the hash grid according to the bandwidth proportion of the member port through a hash load balancing algorithm, so that the distribution of the target weight is completed.
Step S106: and forwarding the network traffic according to the target weight.
In an embodiment, the network traffic is forwarded through the target weight assigned to each member port, which can ensure that the traffic can be forwarded completely without causing traffic loss.
According to the traffic forwarding method provided by the embodiment of the invention, when network equipment receives network traffic, whether the average traffic of the network traffic exceeds the maximum bandwidth of a certain member port in an aggregation group is judged, wherein the average traffic is the traffic distributed to each member port when the network traffic is uniformly forwarded, if so, a target weight is distributed based on the bandwidth proportion of each member port in the aggregation group, and the network traffic is forwarded according to the target weight. By judging whether the average flow exceeds the maximum bandwidth of a certain member port or not, when the average flow exceeds the maximum bandwidth of the certain member port, the target weight is distributed to the bandwidth proportion of each member port in the aggregation group, and the network flow is forwarded according to the target weight, so that the problem of partial flow loss caused by the average flow is solved, and the problem of flow loss caused by the board card performance difference in forwarding of the member port is reduced. Therefore, the embodiment of the invention relieves the problem of partial traffic loss caused by traffic sharing and reduces the problem of traffic loss caused by the difference of board card performance in the forwarding of the member port.
Preferably, since the board card performance of each member port in the aggregation group is different, in order to reduce the pressure of the board card with poor performance, the usage condition of each member port in the aggregation group, such as the CPU usage rate of the board card, may also be periodically detected, and if there is a forwarding board card whose CPU usage rate exceeds a specified threshold, the target weight is reassigned. Optionally, the detection period may be set to a time period of 0.5min, 1min, 2min, or the like, and is selected according to the actual network traffic entering the network device, for example, when the traffic is large, the period may be set to be short, so that the service condition of the board card may be checked in real time.
A user can aggregate a plurality of physical ports of a board card in a device together through configuration to form an aggregation group, and a weight value of a physical port in the aggregation group can be specified in the configuration process, and the default value is 1. And the configuration supports port multiplexing, i.e. the same physical port can be bound into multiple aggregation groups.
In one embodiment, the step S102 may include: when the network equipment receives the network flow, the average flow of the network flow is judged to exceed the maximum bandwidth of a certain member port in the aggregation group based on a rule issued by a user, wherein the rule issued by the user carries information of the aggregation group, so that when the target network flow entering the equipment is received, the target network flow can be uniformly forwarded through the members in the aggregation group, and whether the average flow exceeds the maximum bandwidth allowed by the member port in the aggregation group can be judged.
To be able to determine if the average traffic exceeds the maximum bandwidth allowed by the member ports in the aggregation group, a hash (hash) load balancing algorithm may be used, such as 32 aggregation groups of 0-31, each with its own hash value, where the hash value is a number in the range of 0-1023 of 10 bits. If 3 physical interfaces are added to a certain aggregation group, 1024 hash grids are circularly filled in the order of 0, 1 and 2 until the hash grids are full. The method for calculating the hash value comprises the following 5 algorithms of polling according to a source IP address, a destination IP address, a source IP address + a destination IP address + a source port + a destination port and a port.
When one of the first four algorithms is selected, a number is calculated, the number falls on a hash grid of 0-1023, a corresponding value on the hash grid is obtained, a destination module (module) and a destination interface (port) corresponding to a port are searched by the value, the FPGA fills the value into a switching chip, and the switching chip finally completes the forwarding of the flow. For example, if the flows passing through the aggregation group are all concentrated in the same source/destination IP, the flows are all divided into the same physical port, so that the overload condition of member ports inevitably occurs, which results in flow loss, and at this time, the hash algorithm is dynamically adjusted to be port polling, that is, the entering flows are evenly divided according to the number of ports, thereby ensuring that the flows are normally forwarded. For example, when the device includes 4 boards, i.e., board1, board2, board3 and board4, their maximum traffic forwarding bandwidths are 40G, 10G and 40G, respectively, where G is Gbps. Therefore, 1024 hash grids can be circularly filled according to the sequence of 0, 1, 2 and 3, in order to achieve that the target traffic can be uniformly transferred out from the interface, the target traffic needs to be smaller than the minimum bandwidth value of the interface, otherwise, the traffic is lost. When the network flow entering the device is 40G, the flow is equally divided from the four boards according to the port polling algorithm, and each board forwards the flow of 10G. However, when the network traffic entering the device exceeds 40G, the average time will exceed the maximum bandwidth of 10G boards, and at this time, the target weight is distributed according to the bandwidth ratio of the boards.
For convenience of understanding, referring to a flowchart of a specific traffic forwarding method shown in fig. 2, taking an example that a network traffic entering a device is 80G, boards are still the boards 1, 2, 3, and 4, and their corresponding maximum traffic forwarding bandwidths are 40G, 10G, and 40G, respectively, at this time, when an average traffic exceeds a minimum bandwidth value of an interface, a weight is used to redistribute the proportion of interface forwarding, and after the weight is redistributed, the traffic is not redistributed, but is forwarded proportionally. If the weighted values of the board1 and board4 are 4, then they will be circularly filled with 1024 hash cells again in the order of 0, 1, 2, 3, and their proportional relationship becomes 4: 1: 1: 4 such that the board1 and 4 each retransmit 32G, the board2 and 3 each retransmit 8G, thereby handling more traffic while reducing the pressure on the boards 2 and 3. Preferably, when the target weight is distributed according to the bandwidth proportion, the utilization rate of the CPUs of the boards is dynamically detected, that is, the utilization rate of the CPUs of the boards is periodically detected, so that the situation that when the utilization rate of the CPUs of the boards with poor performance is too high, the weighted values are redistributed, the boards with strong forwarding performance can bear more flow forwarding, the pressure of the boards with poor performance is reduced, and the purpose of dynamically adjusting the flow forwarding is achieved.

By judging whether the average flow exceeds the maximum bandwidth of a certain member port or not, when the average flow exceeds the maximum bandwidth of the certain member port, the target weight is distributed to the bandwidth proportion of each member port in the aggregation group, and the network flow is forwarded according to the target weight, so that the problem of partial flow loss caused by the average flow is solved, and the problem of flow loss caused by the board card performance difference in forwarding of the member port is reduced.
