Consider a scenario where the transmitting host and the
receiving host are separated by two routers.
Suppose the packet length is L= 2000 bits, and that the link
transmission rate R for both the leg is 10Mbps across all
legs
1. What is the transmission delay (the time needed to transmit all
the packets)?
2. Suppose the packet is split into two 1000 bits packet. How long
will (transmission delay) it take for both the packets to reach the
receiver?

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)?"...
Consider a packet switching network. Packets from origin host travel over H hops to reach the destination host. Supppose that the origin host wants to transmit a message that is M bits long. The bit rate of all links is C (bits/sec), and the propoagation delay over every link is D seconds. The message will be broken into packets. Suppose that each packet has a constant overhead of V bits. Let L be the fixed payload of each packet. Thus,...
Two systems are connected by two routers. Both systems and the routers have transmission rates of 1000 bps. Each link has a propagation delay of 10 ms. It takes each router 2ms in order to process the packet (i.e decide where to forward it). Suppose the first system wants to send a 10,000 bit packet to the second system. How long will it take before the receiver system receives the entire packet?
networking question
Consider transmitting a packet from host A to host B via a
router, as shown below:
Suppose that before sending the packet, all the ARP tables (in
the two hosts and in the router) are empty. Assuming
host A knows the IP address of host B, describe all the packets
exchanged before sending the packet to B.

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...
Suppose there are 2 routers in sequence between Host A and Host B, all of which use store-and-forward routing. What is the total end-to-end delay for a packet originating from Host A with destination Host B, under the following conditions. Each of the link transmission rates are 3.7 Mbps The total distance from Host A to Host B along its path of transmisison is 171.6 km The speed of propagation through the transmission medium is is 2.7 x 108 m/s...
Suppose two hosts, Host A and B, are separated by 10,000 kilometers and are connected by a direct link of R-1 Mbps. Suppose the propagation speed over the link is 2.5 10 meters/sec. The propagation delay of the link is dprop (a) Calculate the bandwidth-delay product, R dpop (b) Consider sending a file of 400,000 bits from Host A to Host B. Suppose the file is sent continuously as one large message. What is the maximum number of bits that...
Suppose that Router A and Router B are connected via a 10 Kbps link, and that the two routers are 20 meters apart. Suppose that Router A is transmitting a packet, and that there are 7 additional packets in the queue of the router, when a new packet arrives at Router A. Suppose that 500 bits of the currently-being-transmitted packet has been transmitted by Router A. Also, assume the following a. Every packet consists of 1000 bits. b. Propagation speed...
Consider a two-link network where Host A is connected to the router by a 1 Mbps link with 10 ms propagation delay and the router is connected to Host B by a 15 Mbps link with a 25 ms propagation delay. Host A sends a 1500-byte packet to Host B. What is the transmission delay (in ms) of the packet from Host A to the router?
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...
