What is the total delay of the new packet in arriving at Router B, i.e., how long does it take the new packet to arrive at Router B from the time it arrived at Router A?
Data Communication
Suppose that Router A and Router B are connected via a 0.05 Mbps link
(note, 1 Mbps = 106 bps) and that the link connecting the two routers has
a length of 80 meters. Suppose that Router A is in the process of
transmitting a packet, and that there are 15 additional packets in the
queue of the router, when a new packet arrives at Router A. Assume the
following
a. Every packet consists of 15,000 bits.
b. 5000 bits of the currently-being-transmitted packet has been
transmitted by Router A when the new packet arrives at Router A.
c. Propagation speed of a bit over the link connecting the two routers
is 2 ? 103 meters/sec.
d. Processing delay of a packet at a router takes 1 millisecond (i.e.,
0.001 seconds).
What is the total delay of the new packet in arriving at Router B, i.e., how
long does it take the new packet to arrive at Router B from the time it
arrived at Router A? In your solution, clearly identify all four delay
components the new packet experiences.
