Assume a small communication network, consisting of two user stations and a basestation (BS). The users are recording and transmitting data collected by sensors andare transmitting the data frames using frequency band BW, (uplink). BS only collectsdata and acknowledges them. It uses a different band BWBs (downlink) fortransmissions. The uplink and downlink channels are assumed perfect; no packetsare lost due to bit errors. An Aloha protocol is used to access the medium by the BSand users. The users generate traffic following Poisson distribution, with framegeneration rate lu. The time duration of data frames is Tf whereas the duration ofacknowledgements is TAck: Determine the probability that the frame generated by auser will be lost.

Consider two hosts S and R connected directly by a link. A link has a transmission speed of 107 bits/sec. It uses data packets of size 400 bytes. Data needed to transmitted is 400 bytes. Length of the link is 600 km and the propagation speed are 3 × 108 meter per second. T is the transmission delay and P is the propagation delay. The propagation delay in millisecond and transmission delay in microsecond respectively are
Question 7 Consider the Go-back-N protocol with a sequence number space {0,1,2,3} and a window size N=3, and suppose that the sender wants to send 7 packets in total (excluding retransmissions), where the first packet sent will get sequence number 0. Assume that the 2-nd packet sent by the sender as well as the first ACK with a sequence number of 2 are both lost. All other messages arrive within 1 unit of time, and the sender uses a timeout value of 4 time units before initiating a retransmission. You can assume that the sender sends all packets as soon as possible and we neglect the transmission delay. • List all sequence numbers in the exact order in which they arrive at the receiver. (Note that this includes sequence numbers of packets sent in retransmission.) • What are the values of the send_base and the rcv_base variables after the sender has received the ack for its final packet?
A bit-oriented sliding window protocol uses frames of 4,848 bits and acknowledgements of 46 bits. The physical layer operates at 0.2 Mbit/s and causes bursts of errors, with typically 8 to 12 bits per burst, at an average rate of 4.8 burst/s. The error bursts can be modelled as a Poisson random process. Calculate the probability of success from the viewpoint of the sender (i.e. the probability of the sender receiving a valid positive acknowledgement for a frame that it sent). Round your answer to 3 decimal places.
Let's use an example where a packet is being transmitted along a predetermined path from one host to another. The following is a list of the delay's components. Which of these delays is a fixed one, and which one changes with time?
In selective repeat ARQ, packet size is 2000 bytes transmission time for one packet is 1ms. If distance between hosts is 10km and signal speed is 4ms per km (4ms/km) and frame sequence number are 6 bit long in frame format then the throughput (in Mbps) is
The media material must be played out at the appropriate moment once it reaches the recipient. Because packets take somewhat varying amounts of time to transit the network, this will not be the moment at which the real-time transport protocol (RTP) packet arrived at the receiver. Even if the packets are injected at the transmitter with the exact correct intervals between them, they will arrive at the recipient at various times. Jitter is the term for the fluctuation in delay. We can buffer packets to minimize jitter. Assume that the jitter is changeable and that the buffer size is enough. Explain what additional issues we may face in light of this.

A framing protocol deploys the bit stuffing for the data transmission process. Frame that is transmitted across the link is 01011111 01110011111 00 11111 111110. Mark the stuffed bits in this sequence.
Consider a datagram network in which a packet travels through two switches S1 and S2 from source to destination. Packet experiences wait at each switch before it is forwarded. Transmission time, propagation time and wait time at each node is 3 ms, 1.5 ms, and 0.25 ms respectively. Find the total delay.
