What is the optimal number of equally sized packets that the file should be divided into to minimise the total delay? Assume that the packets are transmitted one after the other in a pipelined manner. Provide a short explanation.

If Host A sends the entire file split into three equally sized packets to Host C, what is the total delay (as a mathematical expression of R, S, D and P) incurred from when the first bit of the first packet is transmitted at Host A till the last bit of the last packet arrives at Host C? Assume that the packets are transmitted one after the other in a pipelined manner. You do not need to provide any explanations. Simply write down the answer in the space provided.

What is the minimum and maximum size of the TCP and UDP segment?

Host A wants to send a large file to Host B. The path from Host B has three links, of rates R1 = 500 Kbps, R2 = 2Mbps and a.             Assuming no other traffic in the network, what is the throughput for the file transfer.b.            Suppose the file is 4 million bytes. Dividing the file size by   throughput, roughly how long will it take to transfer the file to Host B?Repeat (a) and (b), but now with R2 reduced to 100kbps.

Download delays for 100 objects (HTTP 1.0). Consider an HTTP 1.0 client and server. The RTT delay between the client and server is 2 seconds.  Suppose the time a server needs to transmit an object into its outgoing link is 3 seconds, as shown below for the first of these 100 requests. You can assume that any other HTTP message not containing an object sent by the client and server has a negligible (zero) transmission time. Suppose the client makes 100 requests, one after the other, waiting for a reply to a request before sending the next request.Using HTTP 1.0, how much time elapses between the client transmitting the first request, and the receipt of the last requested object?Group of answer choices300 secs700 secs203 secs502 secs500 secs

Suppose a 2-hour ELEN90057 lecture capture is 400MB. If you are to watch the lecture at 2.5x speed, what should be the minimum theoretical bit rate of your internet connection to seamlessly stream the lecture without buffering?
