A circuit-switched TDM-link uses 1024-bit frames over 16 TDM slots'. a. How many 'circuits’ are supported by this configuration? b. If we allowed the TDM-link to be utilized for "TCP connections", how many simultaneous TCP connections could be supported by the TDM link? (Hint: remember TCP connections is a full-duplex bidirectional stream) If the gross bitrate of this link is 8.192Mbit/s, what is the 'frame rate'? C. d. Given the 'gross bitrate', what would the throughput be (in bits/s, Kbits/s, or Mbits/s, as appropriate) for any ONE 'circuit in this configuration?
1. What is the difference between packet fragmentation (i.e., at network layer) and frame frag- mentation (i.e., at link layer) in terms of purpose? 2. Suppose that host A is connected to a router R1, R1 is connected to another router, R2, and R2 is connected to host B. Suppose that a TCP message that contains 800 bytes of data and 20 bytes of TCP header is passed to the IP function at host A for delivery to B. Show the Total length, DF, MF, and Fragment offset fields of the IP header in each packet transmitted over the three links. (Assume that link A-R1 can support a maximum frame size of 1024 bytes including a 14-byte frame header, link R1-R2 can support a maximum frame size of 512 bytes, including an 8-byte frame header, and link R2-B can support a maximum frame size of 432 bytes including a 12-byte frame header.)

4. Consider a datagram network using 8-bit host addresses. Suppose a router uses longest prefix matching and has the following forwarding table: Prefix Match Interface 10 010 1 0110 2 0111 3 11 4 00 For each of the six interfaces, give the associated range of destination host addresses and the number of addresses in the range.
A 10 Mbps link that does not buffer any data is used by a single TCP connection. This link is the only congested link for this connection. The TCP sender has a large file to send and the TCP receiver has sufficient receive buffer space to accept the entire file. The TCP maximum segment size is 1000 bytes and the average round-trip time is 80 ms with very little deviation. Assume that the TCP is always in congestion avoidance phase; no slow-start. What is the maximum congestion window size the TCP connection can achieve? (Select all that apply.) O 1,000 bytes 800,000 bits Cw can be as large as the file that is being sent. 100 MSS 10 Mbits 1 MSS
3.5-1a. TCP RTT estimation and timeout value. Suppose that TCP's current estimated values for the round trip time (estimated RTT) and deviation in the RTT (DevRTT) are 300 msec and 13 msec, respectively. Suppose that the next two measured RTTS are 330 msec and 240 msec respectively. We want to calculate TCP's RTT estimate, and the value of TCP's timeout interval. Note that given a new measured RTT, you should first compute devRTT, then estimated RTT (the textbook incorrectly reverses those computations), and then (lastly) the timeout interval. Use the values of a = 0.125, B = 0.25. Following the newly measured RTT of 330 msec, what is the new value for devRTT in msec? [Note: round your answer to the nearest msec - enter an integer value, do not include any decimal places/point or any leading zeros, but keep your full resolution value of devRTT handy and use it in any later calculations you perform using devRTT.

1. Mention the protocols over which the protocol is encapsulated, to which layer ARP belongs. 2. What is the Target's Hardware Address = a8:9f:ec:bb:78:f0 in the frame and what is the Destination Address = a8:9f:ec:bb:78:f0 in the ARP request packet? Why? 3. Mention the protocol over which the ICMP protocol is encapsulated. - Explain a little in the answers
1. Build a Router network which has three Generic Routers and totally of Six networks in it. From each Router the required switch shall be connected through Fast Ethernet port and the switch is connected to two users. On the whole there are '6' networks in the configuration. Along with the network diagram do the packet transfer in simulation mode and write results for three different combinations.
MAC protocols for an access network with N nodes continuously producing data at a constant rate of x bits per second per node are needed, and you are responsible for developing one. The traffic aggregated across nodes is also less than but close to the entire capacity of the access network, which is another positive development. In your opinion, which protocol is preferable: channel partitioning or random access? For this example, let us assume that you have chosen channel partitioning and that the channel has been divided into N subchannels.
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.
