Consider the diagram showing the nodes A, B and C. Link 1 has a

length 25Km and allows packets to be propagated at a speed of

255 x 10^6m/sec, while Link 2 has a length 5Km and allows

packets to be propagated at a speed of 287 x 10^6m/sec. Link 1

has transmission rate 125Mb/s and Link 2 has transmission rate

300Mb/s

Node A sends a packet P1 of 1200B and then it sends another

packet P2 immediately after it pushes all bits of P1 onto Link

1. What is the smallest size for P2 in Bytes such that there is

no queueing delay at Node B?
