Method for allocating network flow based on external policy server interaction

Abstract

The invention relates to a network flow distribution method based on the external strategy server interaction. The method includes the following steps that firstly, a Web API interface is arranged on a load balancing apparatus; secondly, a terminal client sends a request to the load balancing apparatus; thirdly, the request of the terminal client is packaged in a data packet through the Web API interface by the load balancing apparatus and then forwarded to the external strategy server; fourthly, the data packet is resolved by the external strategy server, the original request of the external strategy server is revised according to the need of the terminal client and then the revised data packet is returned to the load balancing apparatus; fifthly, the load balancing apparatus selects a suitable background server according to the information of the external strategy server and transmits the revised request of the terminal client to the background server; sixthly, the background server responds; lastly, the load balancing apparatus forwards the response from the background server to the request to the terminal client. The network flow distribution method of the invention can integrate the special strategy scheme of the primary client into the algorithm of load balancing and ensure the distribution of the network flow to be fully adaptive to the special application program of the primary client.

Description

technical field [0001] The invention relates to a network flow distribution method, in particular to a network flow distribution method based on external policy server interaction. Background technique [0002] The network traffic distribution method, also known as the load balancing strategy, is a method of evenly distributing the customer's data traffic to multiple back-end servers in traffic management. This method helps to make full use of the functions of all back-end servers. However, with the rapid development of the Internet, traditional load balancing equipment cannot meet the load balancing requirements of many current application services, mainly due to the following reasons: [0003] 1. The application of first-level customers (referring to customers who purchase and use load balancing equipment, mostly large enterprise units such as operators and websites) has certain complexity and particularity. Often there is an effective and targeted algorithm for a specifi...

[0004] 2. The requests faced by the first-level customers are very dynamic, and their rules are often changed. The first-level customers themselves are very aware of this change, and they also know how to update and deal with it

However, the traditional load balancing strategy is pre-set, and it cannot immediately customize the strategy according to the changes of the first-level customers to meet the special needs of the first-level customers.
