Abstract

The widespread use of SIP has exposed a lot of vulnerabilities in this protocol. Among them, overload can cause serious problems for SIP servers. SIP overload occurs when a SIP server does not have enough resources to process messages. In this paper, we proposed effective methods to control SIP server overload based on the Window-Based overload control method, considering not only the maximum window size but also the number of confirmation messages. The proposed method contributes to control the SIP server load as a steady state. It is shown that the suggested method can change the maximum window size dynamically considering the number of confirmation messages.
