III. Computation: C1-5. ( 55 points in total ). The process/procedure or explanation of computation and the correct results are all wanted. C1. (10 points) Consider building a CSMA/CD network running at 100Mbps over a 2-km cable with no repeaters. The signal speed in the cable is 20,000 km/sec. What is the minimum frame size? C2. (13 points) A bit stream 0110110 is transmitted using CRC method. The generator polynomial is x3+ x2+1. a) How many check bits should be added? b) Show the actual bit string transmitted by the sender end. c) Suppose that the second bit from the left is inverted during transmission. Show that this error will be detected by the receiver. C3. (10 points) A channel has a bit rate of 64 kbps and a propagation delay of 2 msec. For what range of frame sizes does stop-and-wait give an efficiency of at least 80 percent? C4. (12 points) A router has the following entries in its routing table: Address/Mask Next hop 130.96.39.0/24 Interface 1 130.96.39.128/25 Interface 0 130.96.40.0/25 Router 1 192.4.10.0/23 Router 2 Default Router 3 For each of the following IP addresses, what does the router do if a packet with that address arrives? Please state why you choose it. 1) 192.4.11.172 2) 130.96.39.135 3) 130.96.39.96 4) 130.96.40.168 5) 130.96.40.64 C5. (10 points) In a subnet, distance vector routing is used, and the following vectors have just come in to router D: from B: (5, 0, 8, 12, 6, 2); from C: (16, 12, 0, 6, 9, 10); and from E: (7, 6, 3, 9, 0, 4). The measured delays to B, C, and E, are 6, 8, and 5, respectively. What is D's new routing table? Give both the outgoing line to use and the expected delay.

A WORD IN YOUR EAR: KEEP IT SLOW AND SIMPLE In 1986 the manufacturers issued their first guide to Simplified Technical English, which was then adopted by the Air Transport Association of America and has since become an international standard. The standard is specific in its instructions, which aim to ensure that once someone has learnt a word in one form, they will not encounter it in another. So manufacturers are told the word "follow11 should always mean "come after" and not "obey". So you can say "obey the safety instructions" but not "follow the safety instructions". You can see why this might be useful in aircraft maintenance books but it would be unnecessarily restrictive in reporting the credit crisis. But at least one news organization has developed a simplified English service, and it did it some time back. The Voice of America broadcast its first program in what it calls "Special English" in 1959. This has a slightly bigger vocabulary — 1,500 words. It also has style rules: use short sentences that contain only one idea. Use the active voice. Do not use idioms. And above all, speak slowly. Special English broadcasters speak at two- thirds of normal speed. To a native speaker, the effect is soporific. To a non-native speaker, the increase in comprehension must be thrilling. Simplified English may not be for everyone, but with the rise in the number of people around the world working in English, I suspect we will see more of it
