URGENT!!!!!!!!! PLEASE ANSWER ALL FOUR FOUR (4) QUESTIONS BELOW:

Assume a five layer TCP/IP model as shown in the class notes. The initial data at the application layer is 170 bytes. A 50 byte header is added at each of the transport, network, and data link layers. The data link layer trailer is 10 bytes. What are the total bytes sent to the hardware? In percentages, what is the overhead?In percentages, what is the portion of the total bytes sent that is data? Show your work to get full credit.

) Go to http://www.rfc-editor.org to look at a couple of Requests for Comment (RFC).

Look up RFC 791, Internet Protocol (IP). Look at the IP header. List each field in the header. (You do not have to explain them, just list them).

Describe the Time to Live field found in the header.

A byte is 8 binary bits.
