- Describe with an image how the process of streaming of stored video occursfrom the video server to the client. Consider a simple scenario with a videoserver with stored videos, a client at his premises, and the internet betweenthem. Explain how HTTP v2 mitigates the head of line blocking. Give an exampleto justify your answerQuestion: Assume a web page consists of 1 base HTML page of 10 KB and 20 images of 50 KB each. If approximate RTT from client to server is 2 μs, compare the response time needed in non-persistent and persistent HTTP. The line bandwidth is 5 Mbps and neglect the idle time.
