  1. Review for Midterm Neil Tang10/17/2008 CS440 Computer Networks

  2. Chapter 1 • Time Division Multiplexing (TDM) VS. Statistical Multiplexing: how do they work, weakness and strength. • OSI 7-layer model and the major functionalities of each layer. • Typical examples of protocols in each layer. • Latency and effective throughput: how to compute. CS440 Computer Networks

  3. Chapter 2 • Shannon’s theorem • Different encoding methods: weakness and strength • Different framing schemes: character/bit stuffing • Three error detection algorithms: how do they work • Sliding window algorithm: procedure, sequence numbers • Ethernet: Exponential backoff, min frame size, weakness and strength • 802.11: the hidden/exposed terminal problems, CSMA/CA, difference • 802.16: scheduling (signaling and algorithm), weakness, strength • Token ring: token passing and token release methods. CS440 Computer Networks

  4. Chapter 3 • Three packet switching schemes: how do they work, weakness and strength • Bridges: spanning tree algorithm • Switch implementation: switch architecture, head-of-line problem, self-routing CS440 Computer Networks
