Consider a simple network that is composed of two computers (A
& B) and a router X in the middle. Computer A is connected to
router X by a link that is 10 Mbps and has a propagation delay of
10 msec. Computer B is connected to router X by a link that is 1000
KBps and has a propagation delay of 20 msec.
a) What is the maximum rate at which computers A
and B can communicate, via router X? (your answer should be in
Mbps)
b) What is the physical distance between router X
and computer B? Assume that the propagation speed of bits in the
medium is 2 3 the speed of light in vacuum. (your answer should be
in Km)
