Calculate total time taken to transfer the file under the following conditions 3. Assume that the link is reliable (no ack needed). How long does it take to transfer a message of 1000 Kbytes? The header size of the message is 100 bytes The file is broken into packets of size 1 Kbyte. Only 1 packet can be sent per RTT The file is broken into packets of size 1 Kbyte. 20 packets can be sent per RTT The file is broken into packets of size 1 Kbyte. Bandwidth is infinite (zero transfer time) The file is broken into packets of size 1 Kbyte. Bandwidth is infinite (zero transfer time) and 20 packets can be sent per RTT a. b. c. d. e. 4. Header lines in http are used to provide additional information to the server as well as to the client. Look up the http standards (www.w3.org/Protocols/rfc2616/rfc2616-sec14.html) and summarize the meaning and use of the following header lines a. Accept-language b. Accept-ranges c. If-unmodified-since d. User-agent
