Consider a short, 10-meter link, over which a sender can transmit at a rate of 150 bits/sec in both directions. Suppose that packets containing data are 100,000 bits long, and packets containing only control (e.g., ACK or handshaking) are 200 bits long. Assume that N parallel connections each get 1/N of the link bandwidth. Now consider the HTTP protocol, and suppose that each downloaded object is 100Kbits long, and that the initial download object contains 10 referenced objects from the same sender. Consider two cases: (i) parallel downloads via parallel instances of non-persistent HTTP and (ii) persistent HTTP. What should be the propagation delay in order for case (i) to outperform case (ii), that is, download the object faster?
