The principal parameters, formats, protocol layers, physical layers, and interfaces of these network architectures are discussed. The course begins by reviewing circuit switching, packet switching, and cell switching concepts, as well as ISDN and X.25. Frame relay protocol, traffic rate management, and network congestion management are also covered. High speed MANs, such as FDDI, FDDI-II, and DQDB are introduced and their operations are described.
SMDS service is reviewed and compared with frame relay service.
Key features of ATM are discussed, such as cell formats, asynchronous multiplexing to mix different traffic types, congestion control, and traffic policing. Finally, the course explores emerging high speed LANs and virtual LANs. A basic course in data communications, such as 525.441 Computer and Data Communication Networks I , or an introductory course in local area networks. Grading The final grade will be based on two exams and homework problems. He is actively engaged in research in image compression, packet video and transmission of video over high speed wide area networks.
