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?### Diagram DescriptionThe diagram illustrates a TCP transaction between two hosts: Host A and Host B. - Host A sends two packets to Host B: - The first packet has the sequence number 80 and contains 20 bytes of data. - The second packet has the sequence number 100 and also contains 20 bytes of data.- A timeout occurs, marked as "1" in red, which means that the first packet did not receive an acknowledgment (ACK) within the expected time.- The second packet is successfully received by Host B, and an ACK is sent back to Host A, marked as "2" in red.- The diagram includes a red "X" indicating a lost packet or communication failure for the packet with sequence number 80.Overall, the diagram is used to explain when Host A will decide to resend packets or send new packets based on the ACKs and timeouts it experiences during the TCP transaction.

According to the question , we have to answer two parts A and B which is computer networking based.…

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
15. Consider the following plot of TCP window size as a function of time (y axis is the congestion window size (segments), and x axis is the transmission round). Assuming that TCP Reno is the protocol experiencing the behavior shown above, answer the following questions. 18 16 14 12 10 00 8 6 4 2 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1) Identify the intervals of time when TCP slow start is operating. 2) After the 5th transmission round, is segment loss detected by a triple duplicate ACK or by a timeout? 3) What is the value of Threshold at the 7th transmission round? 4) What is the value of Threshold at the 15th transmission round?
Below are the two questions, so make sure to answer each part carefully and label the response for each question: 1) Why does TCP implement congestion control if it already has flow control to manage the sender's window? 2) Consider our recent reading [Chiu+89] Analysis of the Increase and Decrease algorithms for congestion avoidance in computer networks. How does this article showcases that TCP is fair?
Answer true or false to the following questions and briefly justify your answer: With GBN, it is possible for the sender to receive an ACK for a packet that falls outside of its current window.
In TCP Vegas, the calculation of Actual Rate is done by dividing the amount of data transmitted in one RTT interval by the length of the RTT. (a) Show that for any TCP, if the window size remains constant, then the amount of data transmitted in one RTT interval is constant once a full window-full is sent. Assume that the sender transmits each segment instantly upon receiving an ACK, packets are not lost and are delivered in order, segments are all the same size, and the first link along the path is not the slowest. (b) Give a timeline sketch showing that the amount of data per RIT above can be less than Congestion Window.
Consider an HTTP server and client as shown in the figure below. Suppose that the RTT delay between the client and server is 13 msecs; the time a server needs to transmit an object into its outgoing link is 1 msecs. Any other HTTP message not containing an object has a negligible (zero) transmission time. Suppose the client again makes 106 requests, one after the other, waiting for a reply to a request before sending the next request. Assume the client is using HTTP 1.1 and the IF-MODIFIED-SINCE header line. Assume 47% of the objects requested have NOT changed since the client downloaded them (before these 106 downloads are performed). Clients RTT delay: t Transmission delay: ta Intemet APACHE Server How much time elapses (in milliseconds) between the client transmitting the first request, and the completion of the last request?
Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes
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 In Python, I am trying to make a client and server code that passes the payload with the requirements. The client has to specify the length of the data packet, up to max, specify how many times to pass the data packet, and specify the server IPv4 address. Both the client and the server need timer functions and compute the time needed to perform the number of sends both the Client and the server need to display the local and remote IPv4 addresses, total time, and bytes per second. Please help, Thanks.
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
In TCP connection, congestion occurs if the load on the network is greater than the capacity of the network. TCP uses the following algorithm to handle congestion. The algorithm is based on the size of the congestion window (cwnd) which starts with one maximum segment size (MSS). The MSS is determined during connection establishment. At each time the whole window of segments is acknowledged (one transmission), the size of the window grows exponentially. To stop this exponential growth, the sender keeps the track of a threshold. The threshold is set to 16 MSS. After reaching the threshold, the size of the congestion window is increased by 1. After how many transmissions the congestion window size will be 22 MSS?
In TCP Fast Retransmit, if we receive three duplicate ACKS after sending out a packet that is not incrementally ACK-ed but before the time-out associated with that packet, we immediately retransmit the packet without waiting for the timeout to occur. Why do we wait for three duplicates instead of just one?
