Problem
1. An ATM system is transmitting cells at the OC-3 rate. Each packet is 48 bytes long, and thus fits into a cell. An interrupt takes 1 pee. What fraction of the CPU is devoted to interrupt handling? Now repeat this problem for 1024-byte packets.
2. What is the probability that a totally garbled ATM header will be accepted as being correct?
3. Suggest a simple modification to Fig. 2-9 that reduces network traffic.
