3. Grading: –Term Project 50% –Presentations (2 times) 30% –Class participation 20%

4. Prerequisite: CEN5515 –Protocol Layers: ISO/OSI, TCP/IP reference models. –Manchester code –Baud, bit, simplex, duplex, half-duplex, modulation/demodulation –Framing, Bit stuffing, byte stuffing –Flow control, error control –Stop and Wait, Sliding window protocols –Error detection: Hamming distance, CRC code

5. Prerequisite: CEN5515 –MAC layer protocols: Aloha, CSMA/CD, Ethernet, Token ring –Extended LANs: Hubs, Bridges (switches) Spanning tree –Network layer: Routing, distance vector, link state Connectionless and connection oriented IP addressing –TCP: Slow start Congestion control –Application layer: DNS, http, etc

6. What will this course cover? Issues related to QoS over data networks –QoS architectures: IntServ, DiffServ, MPLS –Signaling protocol: RSVP –Issues in router support for QoS (packet scheduling) –Issues in end-to-end QoS support (reservation.vs. provisioning) –QoS/constraint/policy based routing –Traffic Engineering QoS application: Voice over IP DWDM networks and QoS over DWDM networks Objective: Understand the research issues in this area.

7. What are you expected to do in this class? –Read the related materials before coming to the class. –Go deep on your own – the lecture will only cover the key concepts. –Term project – start now!!! Literature search –SCI, EI, WWW, books, papers. Reading Writing

8. Potential project topics: –You can choose your own topic, anything related to networking will do. IP QoS: Issues, Protocols and Standards IP QoS: Products and Services QoS Routing Packet scheduling techniques Stateless QoS support techniques QoS in Wireless networks Traffic Engineering: Issues, Protocols, and Standards

9. Potential project topics: MPLS: Issues, Protocols and Standards Voice over IP: Issues, Protocols, and Standards Voice over IP: Products, Services. Virtual Private Networks: Issues, Protocols and Standards Virtual Private Networks: Products and Services Routing and Wavelength Assignment Optical Network management and gMPLS/MPLambdaS QoS over DWDM networks IP over DWDM issues

10. –Next Class: review general networking concepts –What should you do before the class? Decide a term project topic. Preliminary literature search for your topic: –2002, 2001 SIGCOMM, INFOCOM, ICC, GLOBCOM –Can’t find a paper in the above list  you have a bad topic!!!
