32222 data bytes are transferred from client to server over a TCP connection over a point-to- point line using Ethernet frames (total overhead = 26 bytes, assume no interframe gap.). The connection parameters are the following: MSS=1280 for both ends, initial sequence number for client is 543 and for server is 99992. The client initiates the disconnection right after finishing data transmission by sending the FIN flag and server replies by sending the FIN flag. Assume the window size is 20000 bytes on both sides and no options in IP and TCP headers. Also assume one ACK segment is sent for each data segment. (a) Show a diagram of a data frame and a control frame (ACK, SYN, etc). Show how many bytes in each field: Eth header, payload, trailer. Assume padding is used for Ethernet frames with a data length less than 46 bytes. the answers are data: 1306 bytes, control: 72 bytes. I need clear explanation of every field in ethernet frames and how did you know the size of each field?

An HTTP client opens a TCP connection using an initial sequence number (ISN) of 14,534 and the ephemeral port number of 59,100. The server opens the connection with an ISN of 21,732. Show the three TCP segments during the connection establishment if the client defines the rwnd of 4000 and the server defines the rwnd of 5000. Ignore the calculation of the checksum field.
P27. Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 126. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number? If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number? If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?

The first acknowledgment is lost and the second acknowledgment arrives after the first timeout interval. Draw a timing diagram, showing these segments and all other segments and acknowledgments sent. (Assume there is no additional packet loss.) For each segment in your figure, provide the sequence number and the number of bytes of data; for each acknowledgment that you add, provide the acknowledgment number.

Suppose Host A sends two consecutive TCP segments to Host B over a TCP connection. The sequence number of the first segment is 748, and the sequence number of the second one is 995. Determine the size of the payload carried by the first segment. Suppose that the first segment is lost but the second segment arrives at host B. What will be the acknowledgment number of the acknowledgment segment that Host B sends to Host A?

"An application message is segmented into 20 packets, each of which is 2500-byte in size. Calculate the end-to-end delay in milliseconds (ms) for the message when the bit rate for any node is 10 Mbps, the optical path total distance is 1200-km, and the queuing and processing delays are 1-ms and 3-ms, respectively. There are 2 intermediate routers in the path, each of which uses the store and-forward approach. Round your answer to the nearest integer. Question 16 of 37
Consider a client connecting to a web server via a router as shown in Fig.Q2. Client A sends a request to the server to retrieve a 7.5 Mbytes file. Given that the segment size is 50 Kbytes, the round trip time (RTT) between the server and client is 10 ms, the initial slow-start threshold is 16 and the client's buffer always has a storage space of 1 Mbytes. Assume that TCP Reno is used, there is no loss during transmission and the headers of protocols are ignored. 400 Mbps 200 Mbps 400 Mbps Link a Link b Link c Client Web Server Fig.Q2 (a) Describe how the value of sending window changes as a function of time (in units of RTT) during the whole connection time. 2.
