Problems solved by technology

Existing link bundling protocols cannot achieve this function
[0011] Therefore, there is no reliable switch link bundling solution in the prior art that can realize link bundling between multiple switches, and can not realize the independence of management and maintenance of multiple switches after bundling. For the control of load balancing There are also big problems

Embodiment Construction

[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, the embodiments of the present invention are not limited thereto.

[0037] The principle of the embodiment of the present invention is to mark and group each port in the switch, and different groups correspond to different link bundles. Then the labels and grouping information of such ports are exchanged between the switches through hello packets, thereby sharing the grouping information. In this way, each switch saves group information, and can flexibly control the group to which each port of itself belongs. In the whole cluster, each port of the same group adopts a unified standard link bundling protocol to operate to realize link bundling.

[0038] The embodiment of the present invention is essentially an improvement to the existing switch link binding mechanism, and is applicable to the link binding of each port of two or more swi...

Abstract

The present invention provides a cross-switch link binding method, system and switch. The method includes: each switch marks and groups the ports bound by the link; the switches exchange the ports through unicast timing interaction information grouping information; the port in the same group executes a unified standard link bundling protocol operation, and establishes a bundling with the opposite end. Compared with the prior art, the present invention solves the limitation that the traditional link bundling technology can only perform one-to-one bundling between switches, improves the fault tolerance and flexibility of the network, and ensures the independent operation and management of the switches. It has the greatest operability in the process of data arrangement and scheduling.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a link binding method, system and switch across switches. Background technique [0002] With the development of data communication, the requirements for ports are getting higher and higher, and a large number of ports are required to be bound or aggregated. Therefore, the physical port group PORT CHANNEL technology has emerged. The main limitation of existing PORT CHANNEL technology is that it is inherently limited in the number of connections that can be performed between two identical devices. General PORT CHANNEL technology does not allow members of PORT CHANNEL to connect to different switches. There can only be a one-to-one relationship between devices. LACP is used to form channels. Before converging them into PORT CHANNEL, it will confirm that the peers connected to each connection are the same device. [0003] To implement one-to-many link bundling, there ar...
