- Q1.Suppose a client, say C, has established a TCP connection with a server, say S. After establishing the connection, the sender sends two TCP messages with data back-to-back ( the first TCP message with sequence number 32 and the second TCP message with sequence number 100). a. What is the sequence number chosen by the client? What could be the reason for choosing this value of sequence number?b. What is the data size of first and second TCP data messages?c. Suppose the server receives the first and second TCP messages with data with the difference of 100 milliseconds delay. What could be the ACK number for both the TCP data messages from the server side as per the TCP RFC.Provide an example of a protocol at each of the TCP/IP model layers, for example that you have used in the above. Also give an example of overhead added in each of these protocols, e.g. a field in the protocol header. If possible, provide information on the maximum size of each packet, and the size of the header, of each of these example protocols.Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. g) The second segment from webserver was corrupted. So the PC…
- 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.Please solve it correctly and please provide explanation of your answers. A PC and a Web Server are communicating over a TCP connection.

- TCP sessions are full-duplex, which means that data can be sent in either direction during the lifetime of the session. Consider a session in which the connection is established, the client sends 100 data segments, all of them are ACKed, and all of the ACKS are received by the sender, then the session is ended by both sides closing the connect. How many segments in total have the SYN bit of the header set to 1? а. 4 O b. 2 с. O d. 1 е. 209TCP sessions are full-duplex, which means that data can be sent in either direction during the lifetime of the session.

If the second packet is lost, what is the content of the Acknowledgement field sent in response to the third packet? (If you think that no acknowledgement is sent, for example because the third packet is out of order, then answer -1.)
- Draw a NAT Table Entry at the Router for the Computer (A) (shown with a smiley face J) trying to reach the Web Server (listening at Port 80) as shown. You may use dynamic port numbers.For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.In an RPC-like protocol, where numerous requests can be active at the same time and responses can be given in any sequence, the following is possible: Pretend requests are sequentially numbered, and that ACK[N] confirms the receipt of reply[N]. Should the number of ACKs be cumulative? If not, what should happen in the event that an ACK is not received?
