Step by step
Solved in 2 steps
- Suppose host A is sending a large file to host B over a TCP connection. The two end hosts are 10 msec apart (20 msec RTT) connected by a 1 Gbps link. Assume that they are using a packet size of 1000 bytes to transmit the file. For simplicity, ignore ack packets. At least how big would the window size (in packets) have to be for the channel utilization to be greater than 80%?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).In a bit-oriented link-layer protocol, the start and end of a frame are each marked by a flag, which is a sequence of exactly 6 consecutive 1 bits. Bit stuffing is used during the rest of the frame: after sending 5 consecutive 1 bits, a 0 is added. The bits below contain an example frame, with the leftmost bit received first. The content of the frame is a sequence of bytes, sent most significant bit first. Put the values of the first four bytes of the frame content, in order, in the four answer boxes below. You may enter the values in either decimal (e.g. 76, 123) or hexadecimal (e.g. 2a, f7). 00101011111010001111110011100111110000111101111101010110100010010011111101101100100 57−240−123−229
- 4.02. Subnet addressing. Consider the three subnets below, each in the larger 128.119.160/24 network. The following questions are concerned with subnet addressing. Answer each question by selecting a matching answer. Each answer can be used to answer only one question. [Note: You can find more examples of problems similar to this here.] : A 128.119.160/24 48 hosts 21 hosts 50 hosts C A. V What is the maximum number of hosts possible in the larger 128.119.160/24 network? A. 256 B. 2**32 E. v How many bits are needed to be able to address all of the host in subnet C 64 A? D. 6 C. v Suppose that subnet A has a CIDRized subnet address range of 128.119.160.128/26 (hint: 128 is 1000 0000 in binary); Subnet B has an E. 96 CIDRied subnet address range of 128.119.160.64/26. We now want a valid CIDRized IP subnet address range for subnet C of the form 128.119/160.x/26. What is a valid value of x? F. 0True or false 6. Before sending a data packet into a packet-switching network, the source must determine all of the links that the packet will traverse between source and destination. 7. With non-persistent connections between a web browser and a web server, it is possible for a single TCP segment to carry two distinct HTTP request messages.Download delays for 100 objects (HTTP 1.1 with browser caching). Consider an HTTP 1.1 client and server. The RTT delay between the client and server is 2 seconds. Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds, as shown below for the first of these 100 requests. initiate TCP connection RTT request file RTT file received time You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 100 requests, one after the other, waiting for a reply to a request before sending the next request. 352 secs Using HTTP 1.1, how much time elapses between the client transmitting the first request, and the receipt of the last requested object, assuming the client uses the IF- MODIFIED-SINCE header line, and 50% of the objects requested have not changed since the client downloaded them (before these 100 downloads are performed)? 350 secs 252 secs time to…
- Host A and B are communicating over a TCP connection. Host B has already received from Host A all bytes up through byte 23. Suppose Host A then sends two segments to Host B back-to-back. The first and the second segments contain 30 and 50 bytes of data, respectively. In the first segment, the sequence number is 24, the source port number is 3000, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. A. In the second segment sent from Host A to B, what arethe sequence number_________,source port number __________,and destination port number__________?B. If the second segment arrives after the first segment, in the acknowledgment of the second segment, what arethe acknowledgment number___________,the source port number__________,and the destination port number __________?C. If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment,what is the acknowledgment number ___________?D.…B. 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 two 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 RTTO = 5 msecs. The second DNS server contacted has an RTT of 8 msecs. 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=63 msecs. 1. 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? 2. Suppose the HTML object references 4 very small objects on the same web server. Neglecting transmission times, how much time elapses from when the client…Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.10.128/24. Also suppose that Subnet 1 is required to support at least 50 interfaces, Subnet 2 is to support at least 100 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.
