1. Consider the scenarios illustrated in Figures 2.12 and 2.13. Assume the rate of the institutional network is
R_l

and that of the bottleneck link is
R_b
. Suppose there are
N
clients requesting a file of size
L
with HTTP at the same time. For what values of
R_l

would the file transfer takes less time when a proxy is installed at the institutional network? (Assume the RTT between a client and any other host in the institutional network is negligible.)
