Load control method and system thereof

Abstract

The invention provides a load control method and a system. The load control method comprises: generating load information corresponding to service types according to the current load condition of a downstream server; feeding back the load information corresponding to the service types to an upstream server; and implementing the load control to the downstream server by the upstream server according to the load information. The embodiments of the invention provide the technical proposal to realize the load control based on service types and ensure the priority processing of key services when resources are limited.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a load control method and system thereof. Background technique [0002] In a communication system, for any network element, when the number of messages received by the Session Initiation Protocol (SIP, Session Initiation Protocol) server exceeds the number of messages it can process, the SIP server may be overloaded. [0003] In a load control method provided by the prior art, the receiving entity monitors the current resource status of the receiving entity in real time through a monitoring module, and when the monitoring detects that the receiving entity is overloaded, it feeds back to the sending entity that the current resource status of the receiving entity is overloaded, The sending entity adjusts the amount of service requests forwarded to the receiving entity according to the resource conditions of the receiving entity. [0004] For example, a SIP request i...

AI Technical Summary

Problems solved by technology

[0005] Therefore, during the process of creating the present invention, the inventor found at least the following problems in the prior art: In the load control method provided by the prior art, the load information fed back to the upstream server only includes the target address, validity period , load and threshold information, which only generally reflect the processing capabilities of downstream servers for business requests, and upstream servers cannot perform corresponding load processing according to different business types

For example: server resources cannot be allocated according to business types. When a large number of certain business requests occupy server resources, other business requests will not be processed, which may cause some business requests that should be prioritized to be processed to be discarded.
