Abstract :
We present sensing mechanisms that can be used for implicit high-load and overload detection in SIP networks. By means of measurements and simulations we highlight the characteristics of SIP proxy servers for different load situations and using different transport protocols. Each protocol yields to distinctive patterns that encourage deriving an algorithm that is able to estimate a downstream server´s current load.
