- 1) What is the data transmission time to send a 20 GB file over a link with a 1 Gbps line rate? You can assume there is no overhead. (Show your work) 2) How long will it take to upload a 15 GB file to a cloud server with an upload speed of 50 Mbps? You can assume there is no overhead. (Show your work)What is the transmission efficiency of a 5000-byte file sent in response to a web request HTTP, TCP/IP, and Ethernet? Assume the HTTP packet has 120 bytes in addition to the 5000-byte file. Assume that the maximum packet size is 1100 bytes. Hint: that efficiency = user data / total transmission size. Explain Each Step done to obtain the result.Assume a client is connected to the server and has already received an HTML webpage. It reads the webpage, and it now needs to get 3 new files, File A is 5 MB file B is 1 MB and file C is 1 KB. The client requests the files in the order A B C. The link has an RTT (round trip time) of 0.5 seconds and a bandwidth of 8 Mb/s(Megabits per second) (or 1 Megabyte per second). The client can reuse the open connection if the protocol allows it to. For all parts of this problem ignore header sizes, and start the timer when the client sends How long does it take to get file C under HTTP 0? How long does it take to get file C under HTTP 1 (assume the browser does not support pipeling)? How long does it take to get file C under HTTP 2 assuming a frame size of 1 KB and no server push? What event would make HTTP 3 faster than HTTP 2 for this use case (ignore TLS)?
