The learning outcome of this assignment is to illustrate HTTP and its relationship to lower-level protocols. To this end, you are required to study a given HTTP request sent to www.aretha.co.nz and the response returned by www.aretha.co.nz. You will be asked to map the request and response to the lower-level protocols. 1. Assuming that the HTTP request is version 1.1, what is the mandatory HTTP header the request should contain? Please provide the complete header line consisting of both the header field as well as value in the correct format. The size of the HTTP request is 662 bytes. You are asked to calculate packet sizes for the various protocols that lie beneath HTTP. To do so, please assume that you would maximize the packet sizes (think about why you would want to maximize packet sizes). 2. How many TCP packets would you need to send for this HTTP request, ignoring handshakes and re-transmissions? 3. What is the size of the first TCP packet, assuming there are no TCP options? Please provide the answer in bytes. 4. What is the size of the first IP packet, assuming there are no optional flags? Please provide the answer in bytes. 5. What is the size of the first Ethernet packet? In the size calculations, include the fields representing source and destination MAC addresses, type, payload, and the checksum. Please provide the answer in bytes. 6. What is the size of the payload this Ethernet packet carries? Please provide the answer in bytes.
