Answer please..
hdet b) Consider sending a packet contains 1100 bits from Host A to Host B in a store and forward nerwork. There are 10 links (and 9 routers) between A and B, and the links are congested (there Is a queuing delays). Assume propagation delay over the links are negligible. As a packet travels along the route, it encounters an average of 5 packets already waiting in the queue to be transmitted when it arrives at each router, How long does it take for the packet to get to the receiver if the nodes transmit on a "first come first served" basis (in ms)?
as a possible congestion control mechanism in a subnet using virtual circuits internally, a router could refrain from acknowledging a received packet until (1) it knows its last transmission along the virtual circuit was received successfully and (2) it has a free buffer. for simplicity, assume that the routers use a stop-and-wait protocol and that each virtual circuit has one buffer dedicated to it for each direction of traffic. if it takes 7 sec to transmit a packet (data or acknowledgement) and there are n routers on the path, what is the rate at which packets are delivered to the destination host? assume that transmission errors are rare and that the host-router connection is infinitely fast.
Assume there are two hosts X and Y that are connected with the help of a router T having: X-T link of infinite bandwidth. The T-Y link can send one packet per second. T's queue is infinite. You have to measure the load as the number of packets per second sent from X to T also sketch a curve for throughput and the delay, each as a function of load.
