Simulation of Protocol for Initiation of Communication Sessions using dynPLA Model

摘要

In providing voice services, user created and signaling information is transferred over telecommunication networks. While service quality is important as the voice information is transmitted, but not less important characteristic is to identify the establishment time of communication sessions or its components [4]. It is also an important characteristic of packets loss. There exist a number of protocols created for the establishment of communication sessions over IP networks. One of the first standardized protocols is H.323, which has recently being replaced by the Session Initiation Protocol (SIP) protocol [5, 9]. Furthermore, SIP protocol is used as a basis to manage the communication sessions in modern telecommunications networks, based on IP Multimedia Subsystem (IMS) architecture [4]. In SIP protocol, there can be used three types of servers: Proxy.
