Concept explainers

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

Question

[rdt3.0]
Now suppose that the network with a data rate of R b/s can deliver out of order and that
the longest time a packet can be delivered is as much as 10 seconds after subsequent
packets. Assume all packets are of size L bytes. Given the above information, how would you
adjust the sequence number requirements to make rdt3.0 work correctly on this network?

A communication satellite orbits the earth at distance of 30000 miles with each mile having a propagation speed of 5 x 10^(-6) seconds. The data rate of the satellite link is 1 Mb/s. Suppose a data frame is 1250 bytes and that ACKs have negligible processing and transmission times. With the Stop-and-Wait protocol, what is the maximum utilization possible.Discuss ways in which the utilization can be improved. Remember that the satellite is far away and therefore outline the disadvantages to any scheme you propose that may improve the utilization.
hdet b) Consider sending a packet contains 1100 bits from Host A to Host B in a store and forward nerwork. There are 10 links (and 9 routers) between A and B, and the links are congested (there Is a queuing delays). Assume propagation delay over the links are negligible. As a packet travels along the route, it encounters an average of 5 packets already waiting in the queue to be transmitted when it arrives at each router, How long does it take for the packet to get to the receiver if the nodes transmit on a "first come first served" basis (in ms)?
To ensure the quality of service, especially for multiple applications, regulating the rate at which packets are sent to the network is an important strategy. The leaky bucket is just one of such mechanisms. A flow of packets is said to conform to the leaky bucket specification (r, b), where r is the average rate and b is the burst rate, if the number of packets arriving at the leaky bucket is less than r*t + b in every time interval of t. What is the implication of that? What will happen if the number of packets arriving at the leaky bucket is equal to or greater than r*t + b?
I need the answer as soon as possible
In a network, at physical layer, the sender sends the data in continuous binary stream towards receiver, the receiver get confused about how many bits to combine in order to make the frame because the frames are not of fixed size. What you will suggest to make it work properly, suggest a solution that works on any given string. Elaborate your answer with the help of example.
Given a M/M/1 queue, which has packets arriving at a rate 2 packets/sec, an output link rate R bps, and an average packet size of 1500 bytes, write down: the expression for T, the average delay for a packet (i.e., from arrival till completing transmission at the output). b. the expression for the output utilization c. the expression for average number of packets in the queue d. the expression for average number of packets in the output NIC
Let host A sends a file a size of 2200 byte to host B through routers R1, R2, R3, R4 and R5 respectively. Each packet contains 110 bytes of header information along with the user data. Assume that the bandwidth of each link is 106 B/s. File is split into 20 equal parts, and these packets are transmitted from A to B. Consider only transmission time and ignore processing, queuing and propagation delays also no error in transmission. What is the time taken by host A to send the complete file to host B?
