Embodiment Construction

[0022] Combine the following figure 1 and figure 2 An embodiment of the present invention is described:

[0023] figure 1 It is a flowchart of a load sharing adjustment method in an embodiment of the present invention. The method includes:

[0024] 102. Measure the traffic of each link.

[0025] For example, the links here may be trunk ports, tunnels, equal-cost routes, or other links that require load sharing. The traffic of each link can be measured regularly, and the measurement interval can be fixed or configured by the command line. For example, each link traffic can be measured every 5 minutes. It is also possible to measure the traffic of each link according to the traffic change. For example, set a traffic change threshold. When the traffic change between two measurements is greater than the threshold, the measurement time interval is reduced. When the traffic change between two measurements is smaller than the threshold increase the measurement interval. It i...

Abstract

The invention relates to the field of network communication, in particular to a load sharing adjusting method and a load sharing adjusting device. The method comprises the following steps: flow rate of each link is measured; predicted flow rate that is corresponding to each hash value is estimated according to a binding relation between links and hash values as well as the flow rate of each link, and the total number of hash values is more than the number of links; the binding relation between the links and the hash values is adjusted according to the predicted flow rate that is corresponding to each hash value, thus improving the load sharing uniformity. When the technical proposal of the embodiment of the invention is adopted, as the total number of hash values is more than the number of links, the load sharing uniformity of the flow-based routing forwarding technique can be improved by adjusting the binding relation between links and hash values according to the flow rate of each link.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a load sharing adjustment method and device. Background technique [0002] In a network device, there may be several physical or logical links with the same cost to a destination address, and forwarded traffic is sent on these links in turn. The purpose of configuring equal-cost routing or port aggregation (Trunk) or tunnel (Tunnel) is to implement load sharing among multiple links, improve link utilization, and avoid link load unevenness. [0003] Trunk is the meaning of port aggregation, which is to combine two or more physical ports into a logical path through configuration software settings to increase the bandwidth between the switch and the network node, and the bandwidth belonging to these ports Combined to provide the port with an exclusive high bandwidth that is several times that of independent ports. [0004] The link routing technology includes packet-by-packet ...
