Problems solved by technology

The processing of some ongoing calls will not be completed, and the received new calls will not be processed, the success rate of calls will be greatly reduced, and eventually the entire system will be paralyzed, and no calls can be processed anymore

Embodiment Construction

[0021] Embodiments of the present invention provide a method and device for load control of a session initialization protocol stack, and determine whether the SIP protocol stack has reached the limit threshold of processing capacity according to the load usage of all load factors that affect the performance of the SIP protocol stack. After the SIP protocol stack reaches the limit threshold of processing capability, it refuses to receive new call requests. When the processing capability of the SIP protocol stack returns to normal, the system will receive new calls again and perform corresponding processing.

[0022] The method of the present invention will be described in detail below in conjunction with the accompanying drawings. The processing flow of the method according to the embodiment of the present invention is shown in Figure 1, including the following steps:

[0023] Step 1-1. When the sampling period arrives, obtain the load usage situation of the load factor that af...

Abstract

This invention provides a method and a device for controlling loads of SIP, in which, the method includes: judging if the SIP reaches to the limit threshold of its process ability, if so, it refuses receiving new call requests, if the SIP does not reach to the limit, it receives new call and processes it. This invented device includes: a process ability judgement module, a first call process module and a second call process module.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a method and device for controlling the load of a session initialization protocol stack. Background technique [0002] SIP (Session Initiation Protocol, Session Initiation Protocol) is an application layer control protocol, mainly used for establishing, modifying and terminating multimedia sessions. The SIP protocol stack is an implementation of the SIP protocol, which mainly provides various business supports for multimedia sessions. [0003] The SIP protocol stack, like any other protocol stack, has a performance limit. If the number of calls at a certain point in time exceeds the limit value of the processing capability of the SIP protocol stack, some calls need to be stored in the queue and wait for post-processing. If this situation continues for too long, more and more calls will be stored in the queue, so more and more memory is used to store these calls. When the oc...
