An end station sends 135,200 bits into a Frame Relay network in 200 milliseconds. The CIR is 400,000 bits per second and the maximum transmission rate is 1.544 Mbps.
a. Has the user exceeded the maximum transmission rate? (show your work, then answer yes or no)
b. If every frame is exactly 50 octets long, how many of these frames will have the DE bit set to 1?
Explain a network storage technology that can use the existing network to make data on network-connected hard disks accessible to comapny users.
The logic circuit consists of an active high output decoder, an active low decoder and a 4:1 Mux. Write output expressions for f1,f2,f3 and replace logic circuit with a single 4:1 mux
Suppose a propagation speed of 100 km/hour. Assume caravan travels 150 km, beginning in front of tollbooth. Calculate the end-to-end delay.
Several graphic files were transmitted by a e-mail from the unknown source to suspect in the ongoing investigation. Lead investigator provides you these graphics files and tells you that at least four messages must be embedded in them.
The Analog to Digital converter has V(t) as its input, and it outputs a binary word B(t) with a fixed length of k bits, which is its best approximation to V(t). Suppose that V(t) can vary continuously between zero and 5 volts
List and illustrate 5 RFCs that describe the IMAP protocol. Print and read the first two pages of one of these RFCs.

Write a 2 page research paper (excluding the title page) on the five layers of TCP/IP protocol suite. In addition to textbook, use two other resources (Wikipedia sources are not permitted) and list each resource used at the end of paper in the ref..
A draws K=0 and B draws K=2n-1 in exponential backoff protocol. Ignore jam signal and interframe space and suppose that signal propagation speed in medium is 2*108 m/sec. When does station A detects first collision?
Assume two hosts, A and B, are separated by 10,000 kilometers and are connected by direct link of R =1 Mbps. Assume propagation speed over link is 2.5?108 meters/sec .How long does it take to send file, suppose it is sent continuously?
Explain fully why you chose that solution, why it is of more advantage than the other solutions. Explain what other specific (how high, how much power, etc.) choices you might suggest to increase system performance as measured by received signal ..
