Conforming normalised behaviour of SIP server overload control mechanism
Atul Mishra, Ashish Kr. Srivastava, Bikash Upadhyay · 2014
Overload in SIP servers is major hurdle for communications, especially during multimedia sessions or VoIP Calls. Earlier used mechanisms are based on multiplicative decrease with a fixed mathematical factor. This paper laid emphasis on normalization of this mathematical factor and conforming the applicability of probabilistic change during a SIP Server overload condition. This probabilistic change is based on earlier used AIMD algorithm. We show that mechanism is quite effective, preventive, and fair than the AIMD algorithm with a range of mathematical factors. Rate of transmission between the sender and receivers are adjusted accordingly.
