- Consider a two-link network in which Host A has a 1 Mbps connection with a 10 ms propagation delay and the router has a 15 Mbps link with a 25 ms propagation delay. Host A sends Host B a 1500-byte packet. What is the packet transmission delay from the router to Host B (in milliseconds)?Consider sending real-time data from Host A to Host B over a packet-switched network. Host A takes an 8-bit measurement every millisecond, and Host A collects these into 64-byte packets. There is one link between Hosts A and B; its transmission rate is 5 Mbps, its propagation delay is 2 × 108 meters/sec, and its length is 3 km. As soon as Host A gathers a packet, it sends the packet to Host B. How much time elapses from the time that Host A begins to take the first measurement in a packet until the entire packet reaches Host B?A packet switch receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1,500 bytes and the link rate is 2 Mbps. What is the queuing delay for the packet? More generally, what is the queuing delay when all packets have length L, the transmission rate is R, x bits of the currently-being-transmitted packet have been transmitted, and n packets are already in the queue?

Host A is to send a packet of size L bits to host B. d. Suppose host A begins to transmit the packet at time t= 0, at time t=dtrans, where is the last bit of the packet?e. Suppose dprop is greater than dtrans. At time t =dtrans, where is the first bit of the packet? f. Suppose dprop is less than dtrans. At time t =dtrans, where is the first bit of the packet?g. Suppose s = 2.5 x 108 , L=100 bits, and R=28 Kbps. Find the distance m so that dprop = dtrans.Take two hosts, A and B, linked by a single R bps connection. Assume that both hosts are separated by meters and suppose that the propagation rate along the link is meters/sec.Host A is to send an L-bit packet to host B.A. Express the m and s propagation delay, dprop.b. Determine the transfer time in terms of L and R for the packet, dtrans.c.
