1. Calculate the bandwidth-delay product for the following networks: (1) T1 (1.5 Mbps). (2) Ethernet (10 Mbps), (3) T3 (45 Mbps), and (4) STS-3 (155 Mbps). Assume an RTT of 100 msec. Recall that a TCP header has 16 bits reserved for Window Size. What are its implications in light of your calculations?

What differences in traffic patterns account for the fact that STDM is a cost-effective form of multiplexing for a voice telephone network and FDM is a cost-effective form of multiplexing for television and radio networks, yet we reject both as not being cost effective for a general- purpose computer network?
basic data link layer principles (e.g. PPP if modems, maximum frame size in byte, maximum header size, CSMA/CA or CSMA/CD media-access control if any, etc): Your answer

Calculate the delay x bandwidth product for the following links. Use one-way delay, measured from first bit sent to first bit received. (a) 100-Mbps Ethernet with a delay of 10 μs. (b) 100-Mbps Ethernet with a single store-and-forward switch like that of Exercise 16(b), packet size of 12,000 bits, and 10 μs per link propagation delay. (c) 1.5-Mbps T1 link, with a transcontinental one-way delay of 50 ms. (d) 1.5-Mbps T1 link between two groundstations communicating via a satellite in geosynchronous orbit, 35,900 km high. The only delay is speed-of-light propagation delay from Earth to the satellite and back.
Assume there is a 1 Mbps shared connection (e.g. Ethernet bus). How long (in microseconds) does it take to send a 1000-bit frame over this link?
Please solve the following. Thank you.
Use a diagram to illustrate the four-way handshake protocol for channel reservation in IEEE 802.11 (i.e., WiFi). Please indicate the name of each frame, and also the idle period before each frame is transmitted. (Tips: the protocol used is CSMA/CA with RTS/CTS.)
I need the answer as soon as possible
Suppose the third bit from the left is inverted during transmission. Show that this error is detected at the receiver’s end. Show the calculation. (1) Why does Ethernet put a constraint on the minimum frame length of data payload? (2) Consider building a CSMA/CD network running at 1Gbps over a 1-km cable with no repeaters. The signal speed in the cable is 200,000 km/sec. What is the minimum frame size?
