Consider a link, over which a sender can transmit at a rate of 200kbits/sec in both directions. Suppose that packets containing data are 100Kbits long, and packets containing only control information (e.g., ACK) are 200 bits long. Assume that N parallel connections each get 1/N of the linkbandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100 Kbits long, and that the initial downloaded object contains 10 referenced objects from the same sender.

a. What is the delay to get all the 11 objects if

parallel downloads via parallel instances of non-persistent HTTP are used?

b. What is the delay to get all the 11 objects if persistent HTTP is used?(Note: only transmission delays are considered in the above calculation.)
