Abstract

The embodiment of the invention discloses a method for load sharing, comprising the steps of: searching a corresponding first logical output interface according to the destination address of a first message; searching a matched first stream table entry in a stream table according to one or a plurality of fields in the quintuple of the first message; if the length of the stream table output interface of the first stream table entry is greater than or equal to the length of the first message, then sending the first message via the stream table output interface of the first stream table entry; or else, selecting a first physical output interface from a plurality of physical output interfaces, replacing the stream table output interface of the first stream table entry by the first physical output interface, and sending the first message via the first physical output interface. Additionally, the embodiment of the invention further provides a corresponding device for load sharing as well as another method and device for load sharing. Via the method and device for load sharing provided by the embodiment of the invention, the problem of load unbalance caused to traffic Hash can be solved, and the overall utilization rate of the physical output interfaces is increased.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a load sharing method and device. Background technique [0002] Load sharing is a technical means to improve network bandwidth utilization, and has been widely used in communication networks. Load sharing can achieve the following technical effects: [0003] 1. Distributing traffic to multiple links is equivalent to increasing the total bandwidth of the link; [0004] 2. After a link fails, traffic can be forwarded from other links to improve link reliability. [0005] The inventor found that the prior art has the following technical problems: [0006] Hash the traffic and forward the traffic according to the physical outbound interface corresponding to the hash result, which may cause some physical outbound interfaces to be relatively busy and other physical outbound interfaces to be relatively idle, and the overall utilization of the physical outbound ...
