Advanced Internet Services Henning Schulzrinne Dept. of Computer Science Columbia University Fall 2009

Course overview Ü Challenges of the modern Internet Ü Protocol standardization Ü Next-generation Internet issues & architectures Ü from locator-identifier split to content-based networks Ü Multimedia networking & protocols

Multimedia Ü audio and video transmission (RTP) Ü quality of service (Diff. Serv, RVSP, NSIS, economics) Ü media on demand (RTSP, Flash. Video) Ü Internet telephony architecture and protocols (SIP, MGCP, enum) Ü presence, instant messaging (SIMPLE, XMPP) Ü location-based services (GEOPRIV)

Course goals Ü Descriptive: what’s out there Ü deployed, in standardization, research Ü skill-oriented: programming projects, semester running project, measurements, … Ü critical evaluation: why? how else? Ü interactive: discussion + questions in class, on mailing list

Is this the right class for me? Ü This course does not address: Ü web services (SOAP) Ü network security Ü routing Ü You should know: Ü general networking (e. g. , 4119: Tanenbaum, Kurose/Ross, Bertsekas/Gallagher, etc. ) Ü C/C++, maybe Java Ü on Windows and/or Linux
