Embodiment approach

[0041] In an optional implementation manner, the preset allocation rule includes a preset forwarding table, and the process of updating the preset allocation rule may be: Allocate the hash values ​​corresponding to the M entries with the largest rates in the preset rate statistics table to the aggregation group. For the M member ports in the M member ports, select the hash value corresponding to N / M-1 entries from the preset rate statistics table and assign them to each of the M member ports to ensure that each member port corresponds to the entry. The error between the sum of the rates of the 's forwarding table.

[0042] The preset rate statistics table includes N entries, each entry corresponds to a hash value in the preset forwarding table, different entries have different hash values, and N is an integer multiple of the number M of member ports in the aggregation group .

[0043] For ease of understanding, an example is given below. Suppose there are 4 member ports in t...

Abstract

The invention relates to a load balancing method and device, network equipment and a computer readable storage medium, and belongs to the technical field of network communication. The load balancing method comprises the following steps: acquiring a sending port distributed for a to-be-sent message according to a preset distribution rule, wherein the sending port is a member port in an aggregation group; determining a busy state of the sending port; and when the sending port is in the preset busy state, re-determining the target port for sending the message to be sent from the aggregation group. After the sending port is allocated to the to-be-sent message, if the sending port is in the preset busy state, the target port for sending the to-be-sent message needs to be determined again from the aggregation group, so that the probability that the load of the sending flow of each member port in the aggregation group is not uniform is reduced; and therefore, the problem that the network quality is affected by packet loss due to the fact that the load of the transmission flow of each member port in the aggregation group is not uniform is avoided.

Description

technical field [0001] The present application belongs to the technical field of network communication, and in particular relates to a load balancing method, apparatus, network device and computer-readable storage medium. Background technique [0002] A common method of increasing bandwidth is by bundling multiple physical ports together to form a logical port. A combination formed by bundling multiple physical ports together is called an aggregation group, and the physical ports that are bundled together are called member ports of the aggregation group. When sending packets through an aggregation group, you need to consider how to select member ports so that the load of each member port is balanced. [0003] When sending a packet through an aggregation group, when the bandwidth of each member port is the same, the key field in the packet header is usually used to calculate the hash value, and the sending port in the forwarding table is determined by the hash value. Due to...
