The tutorial will provide a discussion of the new Internet-related technologies which have started to complement the "standard" Internet services of email, file transfer and remote login in the past few years.
The tutorial will briefly review the Internet protocol architecture and the guiding architectural principles. Then, the evolution of the Internet protocol suite towards a global, universal network offering both best-effort and guaranteed grades of service will be discussed, with emphasis on IPv6 and the Internet Integrated Services Model and the supporting resource reservation protocol, RSVP. New foundation services also include IP multicast. Standard protocols are now emerging that support multimedia applications: the Real-Time Transport Protocol (RTP) for continuous media, the Real-Time Stream Control Protocol (RTSP) for media-on-demand applications and the Session Initiation Protocol (SIP) for Internet telephony and multimedia conferencing. The current Internet, with its lack of assured QOS, imposes particular requirements on applications to compensate for packet losses, delay variations and a wide range of available bandwidth.
Henning Schulzrinne received his undergraduate degree in economics and electrical engineering from the Technische Hochschule in Darmstadt, Germany, in 1984, his MSEE degree as a Fulbright scholar from the University of Cincinnati, Ohio and his Ph.D. degree from the University of Massachusetts in Amherst, Massachusetts in 1987 and 1992, respectively. From 1992 to 1994, he was a member of technical staff at AT&T Bell Laboratories, Murray Hill. From 1994-1996, he was associate department head at GMD-Fokus (Berlin), before joining the Computer Science and Electrical Engineering departments at Columbia University, New York. His research interests encompass real-time network services, the Internet and modeling and performance evaluation. He is co-author of the Real-Time Protocol (RTP) for real-time Internet services, the signaling protocol for Internet multimedia conferences (SIP) and the stream control protocol for Internet media-on-demand (RTSP). He currently serves as feature editor of IEEE Communications Magazine and IEEE Commmunications Society editor for the IEEE Internet Computing Magazine.
