Embodiment 1

[0045] This embodiment provides a load balancing method, such as figure 2 As shown, the load balancing method includes:

[0046] S201. Run a routing protocol to receive or broadcast link state information with a network device.

[0047] Further, a specific implementation process of receiving or broadcasting link state information communicated with a network device includes: receiving link state information sent by a network device; updating the link state information; broadcasting the updated link state information to other network devices. The specific implementation process of step S201 is not limited to a method listed in this embodiment, and any specific implementation method that can realize the content of step S201 is included in the protection scope of the present invention.

[0048] In practical applications, when step S201 is implemented by a router or a switch, the specific implementation process is: run a routing protocol on the router or switch, and designate th...

Abstract

The invention provides a load balancing method and device. The method comprises the steps: operating a routing protocol, and receiving or broadcasting link status information between network devices; conducting routing computation according to the routing protocol and the link status information to obtain an equivalent multipath routing list item arriving at a front end dispatch server cluster; selecting a path arriving at a target service address from the equivalent multipath routing list item, obtaining a front end dispatch server corresponding to the path so as to send a matched data packet to the corresponding front end dispatch server through the path, and further sending the matched data packet to a corresponding rear end dispatch server. The load balancing method and device solves the problems that a traditional active/standby structure dispatch server cannot deal with too large load, resources are wasted, and the expansibility is poor. A novel master-master structure dispatch server is disclosed, the load balance of the server side is achieved, attach traffic can be resisted at the same time, various relation mechanisms are further avoided, the utilization rate of the resources is increased, and the expansibility is high.

Description

technical field [0001] The invention belongs to the technical field of network communication, and relates to a network data transmission method, in particular to a load balancing method and device. Background technique [0002] Cluster service is the most widely used Internet access technology that provides high stability, reliability, and high concurrency. It is a group of independent servers that behave as a single system in the network and are managed in a single system mode. A server cluster includes multiple servers, and the servers communicate with each other through the Internet; when one of the servers fails, the applications it runs will be automatically taken over by other servers in the cluster or manually defined. In most cases, all servers (or computers) in the cluster system have a common name, and any available server in the cluster system can be used by all network users. Generally speaking, a server cluster system is a cluster system formed by connecting mu...
