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?

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...

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?
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...
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. Consider a packet of length L which begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i=1,2,3. The packet switch delays each packet by dproc. Assuming no queuing delays, in terms of di, si, and Ri, (i=1,2,3), and L, what is the total end-to-end delay for...
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...
Questions: 1. (15pt.) Suppose that a file of 10 bytes is transferred between two hosts, and packet size is 10 bytes. Assume packets are sent back-to-back with no overhead of encapsulation. Calculate the file transmission latency (from first bit sent to last bit received) for (a) Single store-and-forward 1-Gbps switch is in the path, each link introduces a propagation delay of lus, and either queucing or processing delay can be omitted (b) Same as (a) but with three switches; (e)...
Suppose there are 95 packets entering a queue at the same time. Each packet is of size 5 MiB. The link transmission rate is 1.4 Gbps. What is the queueing delay of packet number 25 (in milliseconds, rounded to one decimal place, e.g. 0.01234 seconds would be entered as "12.3") Show steps to get to 719
For this question, let the packet size L = 1000 bytes, the propagation speed s = 2.5 x 108 m/s, the link distance d = 2000 km, and the transmission rate R = 10 Mbps. Assume that 1 Mbyte (megabyte) = 1 x 106 bytes (SI definition). Answer these questions: (a) If 5 packets arrive simultaneously and the queue is initially empty, what is the average queuing delay for all 5 packets.
