Nodal processing A ms Propagation Queuing Transmission (waiting for transmission) B Assume the two hosts on the left of the figure start transmitting packets of 1500 bytes at the same time (at time=0) towards Router B. Suppose the link rates between the hosts and Router A are 4Mbps and the link rate between router A and router B is 4Mbps. One host link has a 2ms propagation delay and the other has a 3ms propagation delay. Router A has a nodal processing delay of 0.3ms. A. Calculate the time router A receives the last bit of the first packet:
