  3. 2. Evaluating Voice over IP phone implementation on a freescale Cortex A9 processor running Linux using open source SIP and WebRTC

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Eric Sjögren; [2016]
    Nyckelord :;

    Sammanfattning : Voice over IP (VoIP) is a methodology that refers to the delivery of multimedia and voice sessions over an Internet connection and it provides an alternative to regular voice calls using phone lines, usually referred to as the Public Switched Telephone Network (PSTN). Web Real-Time Communication (WebRTC) is an API denition for browser-to-browser VoIP applications; the denition acts as a foundation for applications using voice, video, chat, and P2P le sharing in a browser environment without the need of either internal or external plugins.

  7. 5. Design of VoIP Paralleled Client-Server Software for Multicore

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Zeeshan Khan; [2013]
    Nyckelord :;

    Sammanfattning : As "Voice over IP" has become more prevalent and many client and server applications have been designed for them, the VoIP industry has seen the need for faster, more capable systems to keep up. Traditionally, system speed-up has been achieved by increasing clock speeds but, conventional single-core CPU clock rates have peaked a few years ago due to very high power consumption and heating problems.
