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?

Consider sending a file of F bits over a path of Q links. Each link transmits at R bits per second (bps). The network is lightly loaded so that there are no queueing delays. When a form of packet switching is used, the F bits are broken up into packets, each packet with L bits, of which h bits of it are header. Propagation delay is negligible. Let F = 5x104, Q = 20, R = 1 Mbps, L = 1000, and h = 10. c. Suppose the network is a packet-switched virtual circuit network. Denote the VC set-up time by ts = 250 milliseconds. How long does it take to send the file from source to destination?
Consider the GBN protocol with a sender window size of 4 and a sequence number range of 1,024. Suppose that at time t, the next in-order packet that the receiver is expecting has a sequence number of k. Assume that the medium does not reorder messages. Answer the following questions: a. What are the possible sets of sequence numbers inside the sender's window at time !? Justify your answer. b. What are all possible values of the ACK field in all possible messages currently propagating back to the sender at time? Justify your answer.
Please give me correct solution.
Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that packets containing data are 100.000 bits long, and packets containing only control (e.g.. ACK or handshaking) are 200 bits long. Assume that N parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100 Kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender. Would parallel downloads via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Do you expect significant gains over the non-persistent case? Justify and explain your answer.
If feasible, specific descriptions of multiplexors and demultiplexors should be included. How crucial is it to understand the functions of data bits and the selection bit?
In a protocol that uses 5 bits for the sequence-number field, if a packet has the sequence number x, how many packets need to be sent to see a packet with the same sequence number x, assuming that each packet is assigned one sequence number?
22. A datagram subnet allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of a. (a) hops a packet makes per transmission? b. (b) transmissions a packet makes? (c) hops required per received packet?
