Embodiment Construction

[0017] Fig. 1 shows the flow chart of the active / standby load sharing method for the V-Switch system according to an embodiment of the present invention, comprising the following steps:

[0018] Step S10, establish a VLAN path processing strategy for each V-Switch node in the V-Switch path from the user of the source LAN to the user of the destination LAN in the V-Switch system, and configure the path processing strategy of the V-Switch node Load sharing of the main outgoing interface and the backup outgoing interface;

[0019] Step S20, judging the activity status of the primary outgoing interface and the backup outgoing interface; and

[0020] Step S30, configure load sharing on the active primary outbound interface and the backup outbound interface according to the path processing policy.

[0021] The active-standby load sharing method changes the original active-standby links only for failover, and uses the principle of load sharing to improve the utilization rate of netw...

Abstract

The invention provides a method and a device for load sharing by a main outgoing interface and a back-up outgoing interface in a V-Switch system. The method includes the following steps: a route processing strategy of VLAN is established at each V-Switch node inside a user V-Switch route of a local area network that reaches a target of a resource local area network in the V-Switch system; the route processing strategy is deployed with load sharing between the main outgoing interface and the back-up outgoing interface; the action status of the main outgoing interface and the back-up outgoing interface is judged; load sharing is deployed between the active main outgoing interface and the back-up outgoing interface according to the route processing strategy. The invention changes the previous main link and a back-up link which are only used for switching failures and applies the principle of load sharing to improve the utilization rate of network bandwidth.

Description

technical field [0001] The invention relates to the technical field of data network communication, in particular to a load sharing method and device for active and standby links used in a virtual switching system. Background technique [0002] Virtual switching (V-Switch) technology is a method of establishing a virtual circuit. In the V-Switch, the outgoing interface of the message and the virtual local area network (VLAN) ID number are selected by the incoming interface (ingress interface) and the incoming VLAN (Virtual Local Area Network, virtual local area network) ID of the Ethernet message. This technology can enable the three-layer router to achieve the function of switching packets in different VLANs as an analog switch, and it is simpler to implement than MPLS (Multi-Protocol Label Switching, multi-protocol label switching technology). This low-cost technology can be used to build a carrier-class Ethernet bearer network and has attracted widespread attention. [0...
