5. Suppose that node A is directly connected to node B by a link having bandwidth 10 Mbps (mega-bits-per-second). Suppose also that the link is 1 km (kilometer), the propagation delay is meters/sec, and that each transmitted packet has 1000 Bytes. Assume no queueing delay. d. What is the delay between the time node A begins to transmit one packet and the time that the last bit of the packet has been received at node B? e. What is the total time for A to send 10 packets to B if A transmits continuously? 6. Continuing with problem 5: Assume now that there are 3 routers between A and B so that the end-to-end path is A->R1->R2->R3->B with 4 total links. Each link is 1 km in length. Again answer questions 3(a) and 3(b) for this case.
