Method and equipment for realizing load balance continuity

Abstract

The invention discloses a method and equipment for realizing load balance continuity. The load balancing equipment solves the URL link information contained in a message to generate continuity table entries through which the continuity of the load balance is realized. Through the technical scheme, the invention provides a method based on URL information interception for realizing continuity for the load balancing equipment. The method is suitable for the application situation in which the real server rewrites by using URL to realize HTTP conversation persistence, can improve the processing capability of the load balancing equipment and is not affected by that whether the client turns on the Cookie function or not.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for realizing load balance persistence. Background technique [0002] Due to the rapid growth of business volume, access volume and data flow of each core part of the existing network, its processing capacity and calculation intensity also increase correspondingly, making it impossible for a single server device to bear it. In this case, if you throw away the existing equipment and do a lot of hardware upgrades, it will cause a waste of existing resources, and if you face the next increase in business volume, this will lead to another high cost of hardware upgrades. Cost input, even the equipment with excellent performance cannot meet the needs of the current business growth. For this reason, load balancing (Load Balance, LB) technology is introduced to solve such problems. [0003] In the existing technology, a typical load balancing network is as fo...

In this case, the user's browser will not send the cookie identifier back to the server, so the load balancing device cannot ensure that multiple connections in one interaction can be sent to the same real server through cookie persistence.

[0021] 2. In practice, there are a large number of web servers that use the URL rewriting method to implement HTTP session processing. In this case, the load balancing device can only use the cookie insertion method to achieve persistence. This persistence method needs to be in the first response message. Insert the Set-cookie information, and the TCP sequence number and other information of all subsequent messages need to be modified, and the performance is relatively poor

This is because the Cookie method usually inserts Set-cookie information in the first response message, thereby changing the content length of the response message; thus affecting the TCP sequence numbers of all subsequent messages are incorrect, and the load balancing device Each message needs to be modified
