Internet Services: from Electronic Mail to Real-Time Multimedia
نویسنده
چکیده
In the first twenty years of its existence, the Internet was mainly used for email and file transfer, mostly by researchers and technical staff in American universities, government and some industrial research labs. In the last five years, this has changed dramatically, with exponential growth, new services and a transition to a commercial network. This paper describes some of the technical foundations of the new real-time multimedia services, in particular a real-time transport protocol. The paper also outlines some of the challenges to Internet technology in this transition from a research to a commercial network.
