a)

Program Plan Intro

HTTP streaming:

  • The video files are being stored at HTTP server in the form of ordinary file with URL that is specific to the video.
  • The user can watch the videos by establishing a TCP connection with the server.
  • The client issues the HTTP GET request for the requested URL.
  • The server will in turn send the video file through the HTTP response in quick manner.
  • The video requested are delivered as quickly as possible when the congestion control and flow control allows.

6. Consider sending over HTTP a Web page that consists of one video clip, and five images. Suppose that the video clip is transported as 25 frames, and each image has 4 frames. a. If all the video frames are sent first without interleaving, how many "frame times" are needed until all five images are sent? b. If frames are interleaved, how many frame times are needed until all five images are sent.
(a) Suppose a server S and client C are connected over the Internet. The one-way prop- agation delay from S to C is 50 ms. The maximum throughput between S and C is R = 200 Mbps. A browser on client C makes an HTTP request for a webpage on server S. The base HTML file is of size 500 KB and it references five objects, each of size 5 MB. Find the total response time for the client to receive the entire webpage using nonpersistent HTTP with up to two parallel connections. Assume that when two par- allel connections are active, the throughput for each connection is 40% of the maximum throughput R. (b) Suppose an application running on host ece.gmu.edu needs to resolve the domain name cs.vtech.edu. Draw a diagram (with labels) showing the sequence of queries/responses in a recursive DNS query to find the answer in a scenario where all levels of the DNS hierarchy are involved.
Computer A uses the Go-back-N ARQ protocol to send a 110 Mbytes file to computer B with a window size of 15. Given each frame carries 100K bytes data. How long does it take to send the whole file (the total time taken from A sending the first bit of the file until A receiving the last acknowledgment)? Given that the transmission rate of the link is 500 Mbps and the propagation time between A and B is 15ms. Assume no data or control frame is lost or damaged and ignore the overhead due to header and trailer.
