Problems solved by technology

[0013] In the prior art, this kind of load sharing consumes more IP resources. The load sharing is realized through multiple virtual routers, and different virtual routers are distinguished by different virtual IP addresses. In this way, how many virtual routers must occupy how many virtual IP address

Embodiment Construction

[0031] 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.

[0032] In the embodiment of the present invention, by setting the same virtual router address, selectively configuring the user's message characteristics, matching according to the user's message characteristics, and determining the priority of forwarding the message, thereby realizing load sharing. The load sharing method in the embodiment of the present invention can be applied to a network including multiple virtual routers, and the multiple virtual routers are configured by multiple physical routers.

[0033] For the convenience of description, in this embodiment, the networking mode in which the Layer 2 device is a switch is taken as an example, and in Figure 4 Only a simple network model consisting of two physical routers is des...

Abstract

The invention discloses a method, a device and a route for sharing load, belonging to the data communication technology art. The method comprises: setting the same virtual IP address and virtual MAC address for a virtual route and setting the virtual IP address into a gateway address; an exchange receiving the message sent from a subscriber terminal, searching a layer 2 forwarding table based on the destination MAC address of the message to obtain the port corresponding to the MAC address, and transferring the message to the route corresponding to the port; the route receiving the message and match the message based on a predetermined set, if the match is successful, transferring the message. The system for sharing the load includes: the exchange and a plurality of routes. Each route contains a configuration module, a receiving module and a matching module. The invention can assign the same virtual IP address and gateway and match the message characteristic of the subscriber so as to share load and save the IP resources.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a load sharing method, system and routing device. Background technique [0002] VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) is a fault-tolerant protocol, which ensures that when the next-hop router of the host fails, it can be replaced by another router in time, thereby maintaining communication continuity and reliability. In order for VRRP to work, a virtual IP address and virtual MAC address must first be created, thus adding a virtual router to the network. Hosts on this network communicate with the virtual router without knowing anything about the physical routers on this network. Such as figure 1 As shown, a virtual router usually consists of a master router (Master) and a backup router (Backup), and the master router implements a real forwarding function. When the main router fails, the backup router becomes the new m...
