Question

Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536
bytes.
a. What is the maximum value of L such that TCP sequence numbers are not exhausted?
Recall that the TCP sequence number field has 4 bytes.
b. For the L you obtain in (a), find how long it takes to transmit the file. Assume that a total of
66 bytes of transport, network, and data-link header are added to each segment before the
resulting packet is sent out over a 155 Mbps link. Ignore flow control and congestion
control so A can pump out the segments back to back and continuously.

Host A and B are directly connected with a 100 Mbps link. There is one TCP connection between the two hosts, and Host A is sending to Host B an enormous file over this connection. Host A can send its application data into its TCP socket at a rate as high as 120 Mbps but Host B can read out of its TCP receive buffer at a maximum rate of 50 Mbps. Describe the effect of TCP flow control.
Compare GBN, SR, and TCP (no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel) by the receiving host (Host B) and the sending host (Host A) respectively. Suppose Host A sends 5 data segments to Host B, and the 3rd segment (sent from A) is lost. In the end, all 5 data segments have been correctly received by Host B. How many segments has Host A sent in total and how many ACKs has Host B sent in total? What are their sequence numbers? Answer this question for all three protocols. The previous expert did the wrong question and the answer was incorrect. The 3rd packet is lost not the 2nd packet
Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes
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
13. The following figures plot the timeline for sending TCP segments by host A and TCP ACKS by host B, where “seq #” is the value of the sequence number in the TCP header, and "ACK #” is the value of the acknowledge number in the TCP header. Assume that every segment always includes 500 bytes of data, excluding the TCP header. A seg #: 1000 seq #: 1500 seq #: 2000 seq #: 2500 (1) B ACK #: a ACK #: b ACK #: c ACK #: d A seq #: 1000 seq #: 1500 seq #: 2000 seq #: 2500 (2) B ACK #: r ACK #: s TACK 1) In Figure (1), the second ACK sent out by host B gets lost in the network. a) What are the acknowledge numbers a, b, c, and d? b) Will sender A think the segment with seq#=1500 was lost because it never receives the acknowledgement from B containing ACK# = b? 2) In Figure (2), the second TCP segment from host A to host B gets delayed in the network but later arrives at B. What should be the value for the ACK number r, s and t?
