implemented on Asterisk open source proxy and evaluated. The results of implementation show that this

method could practically maintain throughput in case of overload. As we know this is the only overload

of messages that are sent to an overloaded SIP proxy simultaneously. In this paper, first, fuzzy logic was used to regulate accurate size of window and then it was developed, implemented and evaluated on an Asterisk open-source proxy. Implementation results...

The widespread use of Session Initiation Protocol as a signalling protocol has created various challenges.

An important one is that its throughput can be severely degraded when an overload happens in the proxy

server ...

on User Datagram Protocol (UDP), which practically does not result in optimal throughput. To evaluate this approach, an Asterisk open source proxy is used. Our implementation results in the real testbed indicate the efficiency improvement of Asterisk proxy...
