Embodiment Construction

[0025] In order to make the purpose, technical solution and advantages of the present application clearer, the following will clearly and completely describe the technical solution of the present application in combination with specific implementation methods of the present application and corresponding drawings. Apparently, the described implementations are only some of the implementations of this application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0026] The present application provides a method for link aggregation of a traffic forwarding device. The traffic forwarding device may be a device responsible for packet forwarding under different network architectures. For example, the traffic forwarding device may be a switch in a layer-2 network architecture, or a routing dev...

Abstract

The invention discloses a link aggregation method of flow forwarding equipment and the flow forwarding equipment. The flow forwarding equipment is provided with at least two links to be selected, and each link has respective priority. The method comprises the following steps: calculating the historical message flow rate of the flow forwarding equipment for forwarding messages to the at least two links in the current period, and predicting the message flow rate corresponding to the next period based on the message flow rate; comparing the message flow rate with the limited bandwidth of each link in sequence according to the priority, and determining the flow distribution proportion of each link in the next period according to the comparison result; and in the next period, forwarding the message to each link according to the flow distribution proportion. According to the technical scheme provided by the invention, the link aggregation effect can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a link aggregation method of a traffic forwarding device and the traffic forwarding device. Background technique [0002] In the current link aggregation technology, packets can usually be distributed among multiple links according to a load balancing strategy, so that the load of each link can be effectively utilized and waste of idle resources can be avoided. [0003] When using the load balancing strategy to achieve link aggregation, the packets to be forwarded can be distributed to each link in turn through packet polling; the packets with the same hash signature can also be distributed according to the hash signature. The text is forwarded to the same link. [0004] However, this link aggregation technology based on load balancing generally has a premise that the communication quality of each link is equivalent. However, in practical applications, this precondition is...
