Think about the Scenario network. Assume that all hosts A and B have such a configuration. timeout parameters a. Convince the reader that increasing the size of the router's limited buffer may reduce output (out). b. Assume that all hosts adjust their timeout (like TCP) dynamically based on the router's buffer time. Will increasing the buffer size assist to improve output? Why?

Suppose within your web browser you click on a link to obtain a Web page. The IP address for the associated URL is not cached in your local host, so a DNS lookup is necessary to obtain the IP address. Suppose that three DNS servers are visited before your host receives the IP address from DNS. The first DNS server visited is the local DNS cache, with an RTT delay of RTT = 4 msecs. The second and third DNS servers contacted have RTTs of 45 and 24 msecs, respectively. Initially, let's suppose that the Web page associated with the link contains exactly one object, consisting of a small amount of HTML text. Suppose the RTT between the local host and the Web server containing the object is RTTHTTP = 9 msecs. Assuming zero transmission time for the HTML object, how much time elapses from when the client clicks on the link until the client receives the object? (Do not forget the TCP handshake(s).) 82 msecs O 91 msecs O 46 msecs O 67 msecs
Computer Science You are requesting a webpage with three images stored in three different servers. One of the images resides on the same server as the webpage. Assuming that you are using HTTP/1.1, and your web browser can open up to 3 parallel connections. Ignore transmission time, how many persistent TCP connections will you need? And how many RTTs will you need to get the entire web page displayed? Type your answer in the order of the question asked, separated by a comma, no unit of measurement should be used, no space.
Suppose that a Web server runs in Host C on port 80. Suppose this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. Are all of the requests being sent through the same socket at Host C? If they are being passed through different sockets, do both of the sockets have port 80? Discuss and explain.

What will a link-layer switch do when the destination address of a received frame is not in its internal table? a.It notifies the sending host that the frame cannot be delivered. b.It sends the frame out on all ports of the switch except for the port at which the frame was received. c.It sends the frame out on all ports of the switch. d.It drops the frame.
1. It is known that the MAC address is the only address that is used in order to communicate and reach to the destination in the local network. Study the figure below carefully and then answer the following question: Suppose that a data (shown in the figure) has arrived to the router A. The ARP table for Router A is as shown in the figure below. Discuss the necessary steps that are needed for the Router A to prepare the frame for the final hop.

Suppose two TCP connections share a path through a router R. The router's queue size is six segments; each connection has a stable congestion window of three segments. No congestion control is used by these connections. A third TCP connection now is attempted, also through R. The third connection does not use congestion control either. Describe a scenario in which, for at least a while, the third connection gets none of the available bandwidth. and the first two connections proceed with 50% each. Does it matter if the third connection uses slow start? How does full congestion avoidance on the part of the first two connections help solve this? 10:33 am Type a message Dorcon 1 tahir re
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.
Consider the LAN below consisting of 12 computers (A-L) connected by two Ethernet bridges. At t=0 the bridging table entries for both bridges are empty. At t = 1, node L sends to node E, and node E replies immediately (well before the next time step). What are the (MAC address, interface) entries in the bridging tables right after these transmissions? Note: interface = port number a) Left-hand-side bridge: (L,15), (E, 8). Right-hand-side bridge: (L,7), (E, 5). b) Left-hand-side bridge: (L,8), (E, 8). Right-hand-side bridge: (L,7), (E, 7). c) Left-hand-side bridge: (L,15), (E,5). Right-hand-side bridge: (L,7), (E, 8). d) Left-hand-side bridge: (L,8), (E,8). Right-hand-side bridge: (L,7), (E, 7).

Suppose end system A wants to send a large file to end system B. At a very high level, describe how end system A creates packets from the file. When one of these packets arrives to a router, what information in the packet does the router use to determine the link onto which the packet is forwarded? Why is packet switching in the Internet analogous to driving from one city to another and asking directions along the way?
