Total latency is equal to a summation of network delay contributors such as frame transmission time, queuing time, and propagation time. Use the assumptions listed below to answer the questions below. Assumptions: • Host A and Host B are connected to a network. Packets sent from Host A to Host B transit through two Routers, R1 and R2 (Host A ? Router 1? Router 2 -? Host B) • The links that connect the hosts and routers are Ethernet 1000B and are short distance and can be ignored in any further delay calculations • The link between the two routers is 8km long and are connected by a T-1 WAN link (line rate = 1.544Mbps) • a single packet (size = 1500bytes) is routed from Host A to Host B through the network. The two routers, R1 and R2, introduce queuing delay of 3 msec and 5 msec, respectively. • Assume the signal propagation velocity in the T-1 channel = Vp = 2 x 108 m/sec a. Calculate the latency (in msec) required to send the 1500byte packet from Host A to Host B
Suppose a single 802.11n client is connected to an 802.11n access point and there is no other client or access point in the neighborhood. The client senses the medium, then sends an 1,147-Byte frame, and waits for an 169-byte acknowledgement from the AP, and then repeats the process. The data rate on the wireless link is 400 Mbps. Assume DIFS=44 μs and SIFS =15 μs, no propagation delay and no error. Calculate the throughput for this client in Mbps. Calculate up to 1 decimal point.
Given what we know about transmission delay and the following: A web client and a web server separated by one intermediary router. • Each link carries data at 1Mbps with an MTU of 8192 bytes • Each link is 1000 km long with a propagation speed of 250000 km/s • Zero processing and queueing delays • Connection management packets (packets used for opening a connection, confirming a connection and acknowledging receipt of information) contain no data and all packets have 125 bytes of overhead on top of any data they may contain. • The web client makes an HTTP request to the server that is 250 bytes long. • The requested data is 4 kilobytes in size with 500 bytes of overhead for the HTTP status and headers What is the RTT to open the connection? а. b. How long would it take for a web client to complete the request? You can ignore any time needed to close the connection.
Suppose a single 802.11n client is connected to an 802.11n access point and there is no other client or access point in the neighborhood. The client senses the medium, then sends an 1,337-Byte frame, and waits for an 132-byte acknowledgement from the AP, and then repeats the process. The data rate on the wireless link is 400 Mbps. Assume DIFS=47 μs and SIFS =11 μs, no propagation delay and no error. Calculate the throughput for this client in Mbps. Calculate up to 1 decimal point.
Do not copy from other websites Correct and detailed answer will be Upvoted else downvoted. Thank you!
Dont answer from the internet or from other source I will downvote for sure only answer if you have accurate answer other wise I will surely Downvote 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?
dont answer without any knowledge I will dislike for sure
not handwritten A server sends packets to a client via satellite. The packets must traverse one or multiple satellites before they reach their destination. The satellites use store-and-forward packet switching, with a switching time of 100 μsec. If the packets travel a total distance of 29,700 km, how many satellites do the packets have to pass if 1% of the delay is caused by packet switching?
