Problems solved by technology

The reason for requesting message timeout retransmission may also be that the response message is lost or delayed during network transmission due to network jitter
like figure 2 As shown, the response code returned by proxy server 2 to proxy server 1 is 100 Trying response message, which failed to return to proxy server 1 in time, causing proxy server 1 to continuously retransmit the current INVITE request message, and also resulting in a sharp increase in the request volume of proxy server 2 , increasing the load on proxy server 2

Abstract

An embodiment of the present invention provides a server overload control method. The method includes: the client calculates and stores the first time data of each historical transaction; the server calculates the second time data of each historical transaction, and sends it to the client; the client calculates the timeout reference duration of the current transaction according to each of the first time data and each of the second time data within a preset time period; the client calculates the timeout reference duration of the current transaction according to the current transaction The time-out reference duration of the current transaction is calculated, and the client terminal controls the state of the current transaction according to the transaction timeout duration of the current transaction. The invention also provides a server overload control system. The server overload control method and system provided by the present invention can solve the problem of server overload.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular, to a method and system for server overload control. Background technique [0002] In the process of establishing a session through the Session Initiation Protocol (SIP), if the server on the communication path is not congested, usually the SIP session establishment process is as follows: figure 1 As shown: the User Agent Client (UAC) first sends an INVITE request message to the User Agent Server (UAS), and the UAC sends the INVITE request through the proxy server 1 and the proxy server 2 (hereinafter collectively referred to as the proxy server). The message is routed and forwarded to the UAS. After receiving the request message, the UAS replies with response codes of 100Trying, 180Ringing, and 200OK in turn, and sends it to the UAC through the proxy server. [0003] The UAC determines the address information of the UAS based on the response message with ...
