CNRC student seminar Fall'01 series
3:30-4:30  Tuesday, Oct 09, 2001
Conference Room @ Computer Science Dept., 4th floor in Mudd Building.

Speaker: Kundan Singh
Title of the talk: "CINEMA: Columbia InterNet Extensible Multimedia
Architecture"

Abstract:

Internet telephony is defined as the transport of telephone calls over
the Internet.  We have implemented a Session Initiation Protocol (SIP)
based software suite for Internet telephony and installed it within the
Computer Science department, integrating it with the existing PBX
infrastructure.  Our Columbia InterNet Extensible Multimedia
Architecture (CINEMA) provides a test-bed intended to replace the
departmental PBX (telephone switch).  It interworks with the traditional
telephone networks via an IP telephony gateway.  It also serves as a
corporate or campus infrastructure for existing and future services like
web, email, video and streaming media.  Initially intended for a few
users, it will eventually replace the plain old telephones from our
offices, due to the cost benefit and new services it offers.  The talk
gives a brief overview of Internet telephony followed by a description
of our test-bed.  People not so familiar with IP-telephony are also
welcome.
