1. Suppose two hosts, A and B, are separated by 10,000 kilometers and are connected by a direct link of R =1 Mbps. Suppose the propagation speed over the link is 2.5?108 meters/sec.
a. Calculate the bandwidth-delay product, R?tprop.b. Consider sending a file of 400,000 bits from Host A to Host B. Suppose the file is sent continuously as one big message. What is the maximum number of bits that will be in the link at any given time?c. Provide an interpretation of the bandwidth-delay product.d. What is the width (in meters) of a bit in the link? Is it longer than a football field?e. Derive a general expression for the width of a bit in terms of the propagation speed s, the transmission rate R, and the length of the link m.
2. Refer again to problem 1.
a. How long does it take to send the file, assuming it is sent continuously?b. Suppose now the file is broken up into 10 packets with each packet containing 40,000 bits. Suppose that each packet is acknowledged by the receiver and the transmission time of an acknowledgment packet is negligible. Finally, assume that the sender cannot send a packet until the preceding one is acknowledged. How long does it take to send the file?c. Compare the results from (a) and (b).
What size of packet will result in the last bit being transmitted just as the first bit of the packet arrives at the "far end" of the cable?
Let N users participating in audio/video conference by using IP multicasting. How many distinct SSRCs are required?
Write a temperature conversion program. The GUI and event handling setup should be done in the constructor of the class that implements the GUI.
Let N users participating in audio/video conference using IP multicasting. Each user is equipped with microphone, a camera, and speakers. How many distinct canonical names are required?
Suppose that the links and routers in the network never fail and that routing paths used between all source/destination pairs remains constant. In this scenario, does a VC or datagram architecture have more traffic overhead. Why?
Provided that Alice and Bob both suppose that they have the correct public keys for the other party, and supposing that Eve may intercept any messages passed between Alice and Bob, Describe the steps Alice could take in order to ensure that the pub..
A typical signal sequence in synchronous connection contains significant amount of information in addition to just intended message or data.
You have been asked to design a LAN for very successful CPA firm with 5 departments in one building and total of 500 employees.
You have been assigned th task of determining the available wireless methods that could be used to connect buildings to each other and presenting these options to executive team.
Assuming that it is possible to protect the repository from attack, what are the disadvantages of this approach?
Include the devices and type of network circuits you would use. You will need to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way.
The assignment is to alter Minix 3 to count sent processes and print it into table saying who sent and who's receiving. He said we require place to store counts and then print in readable fashion.
