Abstract

Ovaj rad je pokušaj pronalaženja mogućnosti za poboljšanje iskoristivosti prijenosa govornog signala za telefoniju u paketskoj mreži, s posebnom razradom za distribuirana okruženja malih i srednje velikih poslovnih korisnika. U radu je analizirana iskoristivost prijenosa VoIP usluge. Uočeno je da je iskoristivost prijenosa najmanja u ADSL modemskom pristupu, čak ispod 20%, te je provedena daljnja analiza uzroka takve situacije. Predloženo je nekoliko metoda za povećanje efikasnosti u prijenosu VoIP usluge. Predložena je nova metoda povećanja iskoristivosti prijenosa govornog signala za telefoniju u paketskoj mreži, multipleksiranjem datagrama s komprimiranim zaglavljima i tuneliranjem u govornom kanalu. Upotrebom predložene metode moguće je povećanje iskoristivosti za 250% u odnosu na trenutno stanje. Metoda je posebno primjenjiva u distribuiranim okruženjima malih i srednje velikih poslovnih korisnika.

Abstract (english)

The purpose of this thesis is to explore options in transport service optimization for packet network, with particular regard to distributed small and medium business environments telephony. This thesis examine transport efficiency of VoIP service. For ADSL access, transport efficiency is below 20% and additional research of this situation is provided. Methods for VoIP transport service optimization are proposed. New proposed method for VoIP transport service optimization is based on tunelling of multiplexed datagrams with compressed header in speech chanell. Increase of 250% in efficiency is possible. This method is especially applicable in distributed small and medium business environments.
