Answer the following questions:
1. A station running TCP/IP needs to transfer a file to a host. The file contains 1024 bytes. How many bytes, including all of the TCP/IP overhead, would be sent, assuming a payload size of 128 bytes and both systems are running IPv4? (Also assume that the three-way handshake and window size negotiation have been completed and that no errors occur during transmission.)
i) what is the protocol overhead (stated as a percentage)? [3 marks]
ii) perform the same calculation, this time assuming that both clients are using IPv6. [2 marks]
2.  IP is a connection-less protocol, whereas TCP is connection-oriented. How can these two protocols coexist in the same protocol stack? [ ...Read More

Solution Preview - ANSWER 1 Given data: File has to be transferred to host using TCP/IP. The file size is 1024 bytes. Calculating overhead We will assume that both the users were transferring the file using IPv4 protocol, Given data: File size: 1024 bytes Payload size: 128 bytes TCP header and IPv4 header composed of 20 bytes each. Thus, total bytes com
