Problems solved by technology

However, only one of the multiple equal-cost routes for the same virtual service points to the ideal load balancing device that conveys the access request of the virtual service, and the access request sent by the client to the virtual service is likely to be based on a non-ideal load balancing device. The routing information advertised by the device jumps to the non-ideal load balancing device

Abstract

The invention discloses a route publishing method and device, and the method comprises the steps: detecting whether any virtual service configured on load balancing equipment is associated with a priority equipment cluster or not; if yes, detecting whether the load balancing equipment has the highest priority in the priority equipment cluster or not; if yes, the routing information of the virtual service being issued to at least one network device on the client side; and if not, not carrying out routing release of the virtual service. According to the scheme, the priority device cluster is associated with each virtual service, and only the load balancing device with the highest priority in the priority device cluster releases the routing information of the virtual service, so that a plurality of equivalent routes of the same virtual service are prevented from being generated, each access request can be forwarded to the ideal load balancing device for scheduling according to the unique route, and the load balancing equipment cluster can operate correctly and efficiently.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a method and device for routing advertisement. Background technique [0002] When multiple background servers provide the same service externally, a proxy device is usually set to receive access requests from clients in the form of virtual services. The proxy device is generally a load balancing device in the network. [0003] For example, Baidu has multiple background servers to provide search services, and the search services provided by these multiple background servers constitute a virtual service, which will be configured on the load balancing device and have a corresponding virtual address. When the client initiates an access request to Baidu search to this virtual address, the load balancing device will transfer it to one of the background servers that provide Baidu search service according to the virtual address in the received access request to make the ...
