Unformatted text preview: Fall 2009 Assignment 1 Reading: 1. Nader Mir, Computer and Communication Networks , Chapters 1-4. 2. Professor Cantrells survey of Internet and PSTN architectures 3. Professor Cantrells survey of Internet history 4. Professor Cantrells overview of packet networking (corresponding to item 2 in the syllabus) 5. Professor Cantrells review of digital communications (corresponding to items 1 and 3 in the syllabus) Graded Exercises: 1. Nader Mir, Computer and Communication Networks , Chapter 1, Problem 5. 2. Application programmers usually worry about packet loss probabilities, not bit error rates. The purpose of this exercise is to relate the packet loss rate (due to bit errors) to the bit error rate. (Packets can be lost for other reasons, such as buffer spill, router crashes, etc.) Let the bit error rate on a certain point-to-point link be b . We will assume that b 1 . We will assume, also, that errors in different bits of a frame are uncorrelated, and that all frames have exactly...
