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.
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?
