Traffic load balancing method based on leaf-spine topology structure, devices and system

Abstract

The invention relates to the field of mobile communication and particularly relates to a traffic load balancing method based on a leaf-spine topology structure, devices and a system. According to the traffic load balancing method based on the leaf-spine topology structure, a first leaf device sends a plurality of congestion detection messages to a second leaf device through a plurality of paths; each congestion detection message carries a congestion value; the congestion values are used for indicating the congestion degree of the paths passed by the congestion detection messages; and the first leaf device selects at least one path to send data to the second leaf device according to the congestion value of each path. Through application of the scheme provided by the invention, the load balancing of a whole network is realized.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to the traffic load sharing of an Ethernet network. Background technique [0002] In today's Ethernet network, in order to reduce the impact of link failures on services, multiple links are usually mutually backup. When the main link fails, the traffic is switched to the backup link to ensure the quality and reliability of the service Sex. However, this method cannot enable service traffic to be forwarded on the active and standby links at the same time, and cannot effectively utilize the bandwidth of the link. [0003] In order to support traffic load sharing, multiple physical links of the device are usually bundled together to form a logical link, such as figure 1 Shown. figure 1 It is a schematic diagram of a logical link formed by multiple physical links in the prior art. in figure 1 , The server is connected to device 1 through two physical links, and these two physical ...

Problems solved by technology

Even if the DLB algorithm achieves the load sharing of each physical link of the local device, it cannot guarantee that the entire path under the network topology can be load shared without congestion and discarding

[0012] Therefore, no matter whether the static hash algorithm or the DLB algorithm is used, the traffic load sharing of the entire path under the leaf-spine network topology cannot be realized.
