1. Advanced Internet Services Henning Schulzrinne Dept. of Computer Science Columbia University Fall 2003

2. Overview Course outline Prerequisites Assignments Projects Exams

3. Course outline: Internet multimedia Review of Internet architecture – current architecture – challenges to existing models – standardization Internet multimedia architectures: from IP multicast to peer-to-peer Audio and video compression – audio and video programming IP multicast – routing, programming – application layer multicast

4. Course outline Requirements for IP multimedia applications QoS: models, resource reservation, DiffServ Multimedia transport Adaptive applications Internet telephony Application-layer mobility Security issues for multimedia Ubiquitous computing in an Internet framework – service location (DDS, SLP, LDAP, …) Content distribution networks (CDN) Peer-to-peer networks for content distribution and streaming

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

6. Am I in the right room? This course does not address: – web services (SOAP)  Prof. Kaiser’s class – network security  4180 (but some security discussion here) – routing  6998 class this semester You should know: – general networking (e.g., 4119: Tanenbaum, Kurose/Ross, Bertsekas/Gallagher, etc.) – C/C++, maybe Java – on Windows and/or Linux
