8.0. Create a table as in 8.3.1 Simple fixed-window-size analysis for a network A—R1—R2—R3—B. The A-R1 link is infinitely fast. The R1–R2 and R3–B links have a bandwidth delay of 1 packet/second with no additional propagation delay. The R2-R3 link has a bandwidth delay of 1 packet / 2 seconds, and no propagation delay. The reverse B-A direction (for ACKS) is infinitely fast. Assume winsize = 6. (a). Carry out the table for 10 seconds. Note that you will need to show the queue for both R1 and R2. (b). Continue the table at least partially until T=18, in sufficient detail that you can verify that RTT actual for packet 8 is as calculated in the previous exercise. To do this you will need more than 10 packets, but fewer than 16; the use of hex labels A, B, C for packets 10, 11, 12 is a convenient notation.

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. b) Suppose the network is a packet-switched datagram network and a connectionless service is used. How long does it take to send the file?
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?

This elementary problem begins to explore propagation delay andtransmission delay, two central concepts in data networking. Consider two hosts, Aand B, connected by a single link of rate R bps. Suppose that the two hosts areseparated by m meters, and suppose the propagation speed along the link is smeters/sec. Host A is to send a packet of size L bits to Host B. d. Suppose Host A begins to transmit the packet at time t=0 . At time t= ?????? ,where is the last bit of the packet? e. Suppose ????? is greater than ?????? . At time t= ??????, where is the first bit of the packet?f. Suppose ????? is less than ??????. At time t= ?????? , where is the first bit of thepacket?

Consider the extended LAN connected using bridges B1 and B2 in the Figure given below. H1 shown in the figure is a hub which has the property of taking an input on one port and forwarding it on all other ports. Suppose the forwarding tables in the two bridges are empty. List all ports on which a packet will be forwarded by bridges B1 and B2 for the following sequence of data transmissions: a) A sends a packet to C b) E sends a packet to F c) F sends a packet to E d) G sends a packet to E e) D sends a packet to A f) B sends a packet to F
Consider a network with 4 links between two hosts where the maximum allowable packet size is 1000 bits; each link has a transmission rate of 2000 bits per second, except the second link has a transmission rate of 1000 bits per second. How long does it take to send 6000 bits from one host to the other? You may ignore propogation delay, assume there is no other traffic on the network, and assume that no routers drop packets due to queue length. Round your answer to two decimal places.
Consider a scenario in which Host A and Host B want to send messages to Host C. Hosts A and C are connected by a channel that can lose and corrupt (but not reorder) messages. Hosts B and C are connected by another channel (independent of the channel connecting A and C) with the same properties. The transport layer at Host C should alternate in delivering messages from A and B to the layer above (that is, it should first deliver the data from a packet from A, then the data from a packet from B, and so on). Design a stop-and-wait-like error-control protocol for reliably transferring packets from A and B to C, with alternating delivery at C as described above. Give FSM descriptions of A and C.

Assume a simple network of two directly adjacent routers. At time T=0 seconds both sent updates (A -> B "can reach 10.0.0.0 with cost 1", B -> A "can reach 20.0.0.0 with cost 1"). At time T=10 second router B exploded and, as a sad consequence, it stopped sending or receiving any packets. Select all statements that are true: - If at T=15s A sends a packet to 20.0.0.1, A will immediately drop the packet - If at T=15s A sends a packet to 20.0.0.1, it will not reach the destination - If at T=125s A sends a packet to 20.0.0.1, A will immediately drop the packet - At time T=125s node A has no knowledge about the route to 20.0.0.0/24 - If at T=185s A sends a packet to 20.0.0.1, A will immediately drop the packet - At time T=185s node A has no knowledge about the route to 20.0.0.0/24 - If at T=305s A sends a packet to 20.0.0.1, A will immediately drop the packet - At time T=305s node A has no knowledge about the route to 20.0.0.0/24
1.4.12.2 End-to-end Delay. Consider again the network shown above. The links again have transmission rates of R1 = R2 = 100 Mbps (i.e., 100 x 106 bits per second), and each packet is 1 Mbit (106 bits) in size. Assume that the propagation delay is 1 msec per link. What is the end-to-end delay of a packet from when it first begins transmission at the sender, until it is received in full by the server at the end of the rightmost link. Assume store-and forward packet transmission. You can assume the queueing delay is zero. Answer choices: A. 2 x 106 msec b. 2.01 msec C. 1.1 msec D. 2.02 msec 1.4.12.3 Maximum Throughput. Consider again the network shown above. The links again have transmission rates of R1 = R2 = 100 Mbps Assume that the link R2 is fairly shared (as we've seen is done via TCP) between the two sessions. What is the maximum end-to-end throughput achieve by each session, assuming both sessions are sending at the maximum rate possible? Answer choices:…
Can someone help me with this question please? ASAP??!!! 6. Consider a packet of length L which begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1, 2, 3. The packet switch delays each packet by dproc. a. Assuming no queuing delays, in terms of di, si, Ri, (i = 1,2,3), and L, what is the total end-to-end delay for the packet? (10 Points) b. Suppose now the packet is 1,500 bytes, the propagation speed on all three links is 2.5×108 m/s, the transmission rates of all three links are 2 Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5,000 km, the length of the second link is 4,000 km, and the length of the last link is 1,000 km. For these values, what is the end-to-end delay? (15 Points)
