Suppose that N packets are in the queue of a router, and that the router is transmitting a packet. Suppose also that x bits of the currently-being-transmitted packet has been transmitted. Assume that all packets are composed of L bits, and that the output link of the router has a transmission rate of R bits/sec. What is the queuing delay of the Nth (last) packet in the queue of the router?

Suppose N packets arrive simultaneously to a router at which no packets are currently being transmitted or queued. Each packet is of length L and the link has transmission rate R (simple proof is needed). 1) What is the transmission time for the last packet? Solution: 2) What is the queue delay for the 4th packet? — Solution: 3) What is the average queue delay for the first three packets? Solution: 4) What is the average transmission delay for the...

3. Suppose there is exactly one packet switch (or router) between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 = 1Mbps and R2 = 2Mbps, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length 18000bits? Assume that the propagation speed is 2 * 108 meters/sec, the distance between source...

QUESTION 1 "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second that can be transmitted by the link (use a whole number)?"...

1.When a packet arrives at a router, one other packet is halfway done being transmitted on the outbound link and three other packets are waiting to be transmitted. Packets are transmitted in order of arrival. Suppose all packets are 1000 bytes and the link rate is 10 Mbps. What is the queuing delay for the packet in milliseconds (to one decimal place)? 2.A UDP segment has 16 bits allocated for its length. What is the maximum number of bytes of...

Consider a client and a server connected through one router. Assume the router can start transmitting an incoming packet after receiving its first h bytes instead of the whole packet. Suppose that the link rates are R byte/s and that the client transmits one packet with a size of L bytes to the server. What is the end-to-end delay? Assume the propagation, processing, and queuing delays are negligible. Generalize the previous result to a scenario where the client and the...

Suppose N packets are sent, and each packet arrives at rate of L/2R to a link. Suppose the first packet arrives to a link at which no packets are being currently transmitted or queued. Each packet is of length L and the link has a transmission rate R. What is the average queuing delay for the N packets?

Hosts A and B are each connected to a switch S via 1-Gbps links as below. The propagation delay on each link is 20 μs. S is a store-and-forward device; it begins retransmitting a received packet 35μs after it has finished receiving it. Calculate the total time required to transmit 10,000 bits from A to B in the following two cases: When all the 10,000 bits are transmitted in a single packet? When the 10,000 bits are transmitted in two...
