SIP reverzní proxy s funkcí distribuce zátěže

Abstract

Availability of services, regardless of the type, is under increasing pressure. This is also the case with services offered through VoIP technology. The aim of this master thesis is to design and implement a testing environment using open source software, whose main task will be to automatically distribute the load in the form of calls between a group of application servers, taking into account the current load of their processors. The proposed system for load balancing is tested and evaluated at the end of the thesis in terms of its performance, reliability and possible deployment in a real environment. The introductory theoretical part of the thesis consists of a brief description of the SIP signaling protocol, which is followed by chapters dealing with the description of the principle of operation and features of SIP servers Kamailio and Asterisk.
