Note: b denotes bits and B denotes Bytes (1 Byte = 8 bits). Consider a packet of length L, which begins at source and travels over seven links to a destination. These links are connected through six routers. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1 to 7. The processing delay at each router is d-proc. The queuing delay at each router is d-que. What is 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...
Problem 2 For a given network, the average packet length L = 1024 bytes, packets are arriving with an average rate = 8 pakets/s, the network is used to support voice call services which can tolerate a maximum end-to-end delay of 150 ms, the average end-to-end distance between any two connected nodes in the network is 1000 km, the average phase velocity for signal travelling throughout the network links is 0.1 speed of light in free space and the call...
Q2.3. (15%) Consider sending a file of F bytes over a path of Q links. Each link transmits at R bps. The network is lightly loaded so that there are no queuing delays at any link. The propagation delay on each link is Tp seconds on average. 1. Suppose the network is a packet-switched virtual-circuit network. Assume the VC setup time is Ts seconds. Suppose the sending layers add a total of h bits of header to the file, and...
Given three packets of size 1500 bytes each are ready inside Computer 1 to be transmitted onto Link 1. Computer 1 has zero processing delay. Assume each router has zero queuing and zero processing delay. Link 1 is a 10 Mbit/sec link and 5000 km long. Link 2 is 100 Mbits/sec and is 5000 km long. Link 3 is 1000 Mbits/sec and is 5000 km long. Propagation speed is 2 × 10 8 m/s. Assume a router has to receive...
Need help with this question urgently! If all questions could be answered that would be amazing, if only one or two that'd still be greatly appreciated.. Instruction: Use the free space propagation speed of light 3x10 m/s to calculate the propagation delay. For numerical calculations; result must show appropriate unit. Show complete solution of each problem in your submitted document 1. Consider a two hop network shown in figure 1. Node A sends data packets to the server via the...
Consider sending a large file of Z bits from Host A to Host B. There are four links (and three switches) between A and B, and the links are uncongested (that is, no queuing delays). Host A segments the file segments of S bits each and adds 60 bits of header to each segment, forming packets of L 60S bits. Each link has a transmitting rte of R bps. Propagation delay is ρ microseconds kilometer. Consider the following distances: A...
Question 18 1 pts Consider a message that is 4,000,000 bits long that is to be sent from source to destination in the packet switching network in the figure below, where it passes through two routers. Each link is 1,000,000 bps. Ignore propagation, queuing, and processing delays. The message is sent whole from source to destination. What is the exact total time in seconds to move the message from source host to destination host? Message

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)...
