Embodiment Construction

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0025] The present invention discloses a device and method for realizing multi-system link aggregation by using a protection switching mechanism. By creating a protection group for each multi-system link aggregation group, and according to the identification bit configured in the protection group, the data flow is realized in multiple Fast protection switching between member ports of the system link aggregation group.

[0026] In the embodiment of the present invention, four multi-system link aggregation groups composed of four devices, switches A and B are taken as an example to describe the technical solution of the present invention in detail. like figure 1 As shown, the interface 1 port (Port1) of switch A and switch B together form the multi-system link aggregation group 1, the ...

Abstract

The present invention discloses a device and method of using a protection switching mechanism to realize multi-system link aggregation. A protection set is bound on each multi-system link aggregation set formed by switch ports, and each protection set comprises a W / P identification bit, a working interface and a protection interface. After receiving a message from an own upper connection port, a switch searches a forwarding table according to a destination MAC address in the message and a VLAN to find a corresponding out interface, namely the protection set, and according to the W / P identification bit of the protection set, the message is sent out from the working interface of the protection set or the protection interface of the protection set. According to the present invention, by just needing to set the identification bits as 1, the protection switching of the protection sets can be realized, so that the switching operation is simpler and faster, and the scenes having higher switching speed requirements can be satisfied.

Description

technical field [0001] The invention relates to multi-system link aggregation group technology, in particular to a device and method for realizing multi-system link aggregation by using a protection switching mechanism. Background technique [0002] For the requirement of redundant protection, there are a series of existing technologies in the traditional network, such as STP (SpanningTreeProtocol, Spanning Tree Protocol) / RSTP (rapidspanningTreeProtocol, Rapid Spanning Tree Protocol) / MSTP (Multi-spanningTreeProtocol, Multiple Spanning Tree Protocol) . After using the spanning tree protocol, in order to avoid loops, there will be a link in a block (blocking) state. Therefore, this way to achieve redundancy does not increase the actual network bandwidth. [0003] However, the existing methods that can realize both redundant protection and load sharing are the most common in Layer 2 (L2) is Link Aggregation Group (LAG), and in Layer 3 (L3) it is mainly ECMP (Multiple Equal Co...
