Problem 3 Consider N users trying to download a web page containing a small HTML file (i.e., size negligible) referencing a data file of F bits from a web server through the network shown in Fig. 1. Suppose the internal links have abun- dant bandwidth, and the edge links have bandwidth shown in the figure. Ignore DNS query delays. u: server upload d: user i download file, size F bits erver network with abundant bandwidth 4, u; user i upload capacity Figure 1: Problem 3 illustration. a) Suppose N = 1 (only one user). The path from the user to the server has a round-trip delay of RTT seconds and a throughput of u, bps. How long does it take for the user to download the web page using non-persistent HTTP? [2 pt] How about using persistent HTTP? 12 pt of downloading the data file to the completion of downloading at the last user, under: client-server architecture [2 pt] and P2P architecture [2 pt. c) Give the numerical answer for b) for F = 100M bits, N = 3, us-211 bps, dy d2 ds 10M bps, uu 1M bps, us 2M bps.
