Consider a short, $20-$meter link, over which a sender can transmit at a rate of $250$ bits$/$sec in both

directions. Suppose that packets containing data are $85,000$ bits long, and packets containing only control $($e$.$g$.,$ ACK

or handshaking$)$ are $150$ bits long. Assume that N parallel connections each get $1/$N of the link bandwidth. Now

consider the non$-$persistent HTTP protocol, and suppose that each object can be carried in a single data packet,

and that the initial downloaded object contains $12$ referenced objects from the same sender$.$ What is the total time

needed to download the total $13$ objects? $(0\mathrm{.}8$ points$)$ Now consider persistent HTTP$.$ Do you expect significant

gains over the non$-$persistent case? Justify and explain your answer $(0\mathrm{.}7$ points$).($Hint: The signal propagation

delay can be neglected$)$
