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

• 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

• 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.

• 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

• 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

• 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

– 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!!!
