The purpose of my thesis is to describe the operation of a music player system based on the SIP protocol and to implement the most important parts of its algorithm.
In the first part of my thesis I examine the theoritical background of the network communication and with the help of the ISO-OSI reference model I introduce the most important protocols which are indispensable for the realization of the project.
In the second part of my thesis I specify the operation of the SIP based network music player system imagined by myself. Furthermore I design and implement one module of the complex system.
Finally I analyse the application in a test environment designed for this project.
