Alice wants to send a message to Bob, Assuming they are using the TCP/IP connection stack, and the following information describes the connection: ? The message size is 10MB ? The maximum that could be sent at a time is 64KB (data + header) Answer the following questions: ? How would the message will be processed (Hint: refer to Protocol Data Unit PDU topic) ? Assuming the message is an HTTP request, what would be the source and destination port number. Also, Do you think the transmission protocol used will be (TCP or UDP)? Justify your answer.

Q2: Describe the Head of Line Blocking (HOL) problem in HTTP/1. Does HTTP/2 suffer from the same problem? If Yes, explain how the HTTP/2 protocol solves the problem.

q3: What is the main objective of software-defined networking? How is software-defined networking different than conventional computer networks?

q4: What are the differences between the switch and hub? Is there a time when a switch will act as a hub?

Q8: Given the following topology, answer the following: How many collisions and broadcast domains? Suppose you replace the hub device with six ports switch configured with three virtual local area networks. How many collision and broadcast domains? Justify your answer. Based on the changes done in step 2, PC8 is unable to communicate with PC9. Why do you think the reason might be? How can PC8 communicate with PC9?
