1) Assume a TCP sender is continuously sending 1162-byte segment. If a TCP receiver advertises a window size of 7873 bytes, and with a link transmission rate 23 Mbps an end-to-end propagation delay of 32 ms, what is the utilization? Assume no errors, no processing or queueing delay, and ACKs transmit instantly. Also assume the sender will not transmit a non-full segment.

2) Given a nodal delay of 62.9ms when there is no traffic on the network (i. e. usage = 0%), what is the effective delay when network usage = 83.7% ?

3) Given a effective delay of 27ms when network usage is 97%, what is the effective delay when network usage = 31% ?

This assignment continues work on the online booking facility introduced at the end of chapter- 10. the work will be continued in the assignments for chapters 14 and 15 (a) assume that you will produce your online booking facility using an agile approach. i. suggest the kind of user research you would like to conduct for your product before iteration cycles begin. ii prioritize the requirements for your product according to business value, i. e which requirements are likely to provide the greatest business benefit, and sketch out the ux design work you would expect to undertake during the first four iteration cycles, i. e. cycle 0, and cycles 1 to 3. (b) using one of the mockup tools introduced above, generate a mockup of your product's landing page, as developed in the assignment for chapter-11 (c) using one of the patterns websites listed previously, identify suitable interaction patterns for elements of your product, and develop a software-based prototype that incorporates all the feedback and the results of the user experience mapping achieved at the end of chapter-11. if you do not have experience in using any of these, create a few html web pages to represent the basic structure of your website
