EE450, Fall 2006, Homework #5 Due: Thursday, October 2 6th Reading: Chapter 5, sections 5.5 and 5.6 Chapter 6, section 6.3 Chapter 4, sections 4.3, 4.4 and 4.5 Problems Text Problems: 1. Chapter 5, #11, # 12, # 13 ( Prop. speed=1.8*10^8 m/s) , # 15 (Prop. speed=2*10^8m/s) Supplementary Problems: 2. A group of 32 stations is serviced by a Token Ring LAN. Calculate the time it takes to transmit a frame and the throughput of the ring for each of the following cases. Assume each frame is 1000 bits long, assume 50 meters between stations, assume an 8-bit latency per node and assume a 100 Mbps ring and a propagation speed of 2.5 * 10^8 m/s.

Unformatted text preview: ! Case 1: Token is released after completion of transmission ! Case 2: Token is released after return of the Token ! Case 3: Token is released after return of the frame. 3. Eight stations are connected to a 1km token ring. The data rate is 1 Mbps. Every station introduces a 1-bit delay. The maximum token holding time for each station is 1 ms. After a station releases the token, it sees the token again after x seconds. Assume the speed of propagation is 2x10 8 m/sec. Find the minimum and the maximum values of x ....
