Embodiment Construction

[0095] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0096] Please refer to figure 1 , which shows a schematic diagram of an implementation environment involved in various embodiments of the present invention. The implementation environment provides a VXLAN network reference architecture 100, and the VXLAN network reference architecture 100 may include at least two leaf switches and at least two spine switches.

[0097] Among them, the leaf switch is used to provide access services for terminal equipment such as a virtual host (English: virtual machine, referred to as VM), a personal computer (English: personalcomputer, referred to as PC), and a server (server). Communication between leaf switches on different VXLAN networks can also be carried out through IP networks; spine switches ar...

Abstract

The invention discloses a message processing method, device and system and belongs to the exchange technical field. The message processing method, device and system are applied to a first switch in a VXLAN. At least two equivalent paths exist between the first switch and a second switch. The method includes the following steps that: a first VXLAN message is sent to the second switch through a first path in the at least two equivalent paths; a second VXLAN message is received; whether the first VXLAN message satisfies a path switching condition is judged according to the second VXLAN message; and if the first VXLAN message satisfies the path switching condition, subsequent VXLAN messages which belong to the same data stream as the first VXLAN message are sent to the second switch through a second path in the at least two equivalent paths. With the message processing method, device and system of the invention adopted, the problem of performance degradation of a system caused by a situation that sub data streams are sent with preset time intervals can be solved, and the performance of the system can be improved, and disordering of messages can be avoided.

Description

technical field [0001] The present invention relates to the field of switching technology, in particular to a message processing method, device and system. Background technique [0002] Virtual Extensible Local Area Network (English: VirtualeXtensibleLocalAreaNetwork, referred to as: VXLAN) is a virtual Ethernet built on a physical Internet Protocol (English: Internet Protocol, referred to as: IP) network. In the VXLAN network, in order to increase the link bandwidth, an equal cost multipath (English: EqualCostMultiplepath, ECMP for short) technology is adopted. The ECMP technology enables a data frame of a single service in a shortest path bridge mode (English: ShortestPathBridgingMACMode, SPBM for short) network to select multiple possible next hops (that is, select multiple possible paths). In order to realize path load balancing, there are two path selection methods using ECMP technology, packet-by-packet hash (hash) and flow-by-flow hash. In packet-by-packet hashing, ...
