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 the following scenario in which host A is sending a file to host B over a TCP connection. Assuming that the sequence number of the first data byte sent by A is 0 and every segment always includes 1000 bytes of data, excluding the TCP header. At some point of time, bytes up to 6400 have been written into the sender’s buffer. Bytes up to 4999 have been sent out but the segment which contains bytes 2000~2999 has not arrived at host B yet. At the receiver’s side, all bytes up to 3999 have been received except for bytes 2000~2999. Bytes up to 499 have been read from the buffer by the application. Assume that the maximum size of the sender’s buffer is large enough. Consider the sliding window algorithm in TCP and answer the following questions. 1) What are the values for LastByteAcked, LastByteSent, and LastByteWritten? 2) What are the values for LastByteRead, NextByteExpected, and LastByteRcvd? 3) Assuming that the maximum size of the receiver’s buffer is 4000 byte, what would…
Draw a complete TCP 3-way handshake logical diagram of an HTTP session with a website session.
Three-way handshake is used by a TCP client and a TCP server to establish a connection, as illustrated below: 1st: client:port1 -> server:port2, SYN 2nd: server:port2 -> client:port1, SYNACK 3rd: client:port1 -> server:port2, ACK When this client is performing scanning attacks, it will generated a large number of failed connections. In each failed connection, the three-way handshake fails to complete. People commonly use SYN together with the absence of its corresponding SYNACK in this same TCP session to identify whether this connection is failed. By investigating the failed connections, an engineer finds that in legitimate/benign cases, if the server does not return SYNACK to the client, the client will not send the ACK packet after SYNACK (e.g., the 3rd packet above). Therefore, this engineer suggests that we can count the failed connections based on the following rules without considering SYNACK: If a client:port1 sends…
14 The following figure shows a TCP transaction. Assume Host A always has data to send, and each packet has size 20 Bytes. Assume Host A has a sending window of 40 Bytes, that is, it can send two "in-flight” packets maximum. Answer the following questions. A. At the time marked "1", i.e., when the first packet times out, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them? B. At the time marked "2", i.e., when the ACK of the 2nd packet is received by Host A, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them? Host A Host B Seq=80, 20 bytes of data Seq=100, 20 bytes of data Xª 1 2- timeout
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
True 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.
Question 23 A client's browser sends an HTTP request to a website. The website responds with a handshake and sets up a TCP connection. The connection setup takes 2.1 ms, including the RTT. The browser then sends the request for the website's index file. The index file references 8 additional images, which are to be requested/downloaded by the client's browser. Assuming all other conditions are equal, how much longer would non-persistent HTTP take than persistent HTTP? (Give answer in milliseconds, without units, rounded to one decimal place. For an answer of 0.01005 seconds, you would enter "10.1" without the quotes.)

Answer truthfully or falsely. A single TCP segment may contain two different HTTP request messages when there are no permanent connections between the browser and origin server.
A workstation uses the HTTP protocol to download a large file from a web server. No proxy server is used. One router's queue is full when one of the web server's packets arrives.Select the four best statements to describe this situationa. The router stores the packet until such time that it can be sent.b. Further packets sent by the server are transmitted at a higher rate to compensate for the lost packet.c. The router sends an ICMP link congested message to the server.d. The packet must be retransmitted.e. Router configuration and network behavior could be improved by configuring FQ or WFQ.f. Further packets sent by the server are transmitted at a lower rate to reduce the load on the congested link.g. Router configuration and network behavior could be improved by configuring RED or WRED.h. A tail drop will happen.
Computer Science Networks and should be done in C language. Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threads
