An Efficient Interworking Between Heterogeneous Networks Protocols and Multimedia Computing Applications

Nowadays, Multimedia Communication has been developed and improved rapidly to allow users to communicate between each other over the Internet. In general, the multimedia communication consists of audio, video, and instant messages communication. The interworking between protocols is a very critical issue due to solving the communication problems between any two protocols, as well as it enables people around the world to talk with each other at anywhere and anytime even they use different protocols. Providing interoperability between different signaling protocols and multimedia applications will take the advantages of more than one protocol. This paper surveys the interworking functions between different VoIP protocols (i.e. InterAsterisk eXchange Protocol, Session Initiation Protocol, and H.323 protocol), Multimedia Conferencing System (i.e. Real Time Switching Control Protocol and Multipoint File Transfer System), and multimedia applications (i.e. ISO MPEG-4 standards). At the end, a comparison has been recognized among these protocols in terms of call setup format, media transport, code etc.
