  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

  7. Course mechanics • Web page: http://www.cs.columbia.edu/6181 • Email list: cs6181@cs.columbia.edu • subscribe at http://lists.cs.columbia.edu/mailman/listinfo/cs6181 • 5 written homework assignments, with small programming problems • Project: Internet multimedia radio + telephone, built in stages • TA: TBA • Office hours: We, 4-5 pm, 815 CEPSR • Grading: assignments (including semester-long project) 50%, midterm 20%, final 25%, participation (class + list) 5%

  8. Readings and text book • No text book required • Will provide references to papers and chapters • Good books include: • Jon Crowcroft, Mark Handley, Ian Wakeman, Internetworking Multimedia, Morgan Kaufman • Kevin Jeffay and HongJiang Zhang, Readings in Multimedia Computing and Networking, Morgan Kaufman
