Softwarová aplikace pro komunikaci pomocí VoIP

Abstract

This thesis deals with the developing of application for text, binary and voice communication using internet or other networks based on IP protocol. The goal is to create complete system for communication, especially in telephony. The thesis contains description of properties, parameters and behaviour, analysis of problems, draft of model and structure of complete communication system and description of parts of application. There is mentioned techniques used in implementation, principles of network direct connections and safe transfers based on UDP protocol, voice compression, performance optimizations by multithreading techniques. Text descriptions are ensembled by diagrams.
