Problem 4 Consider the problem of transferring a bunch of files that are 20GB in size between San Marcos and Austin You would like to send these files as fast as possible. You can use FedEx service or you could use your Internet connection which you can assume to be 10 Mbps in capacity and has 10 msec propagation delay. You can assume that transferring the files over the Internet connection would incur an extra 5% of overhead due to the headers. Answer the following questions [2 pts each]: (a) How long would it take to send these files over your Internet connection? (b) If it would take FedEx 30 mins to deliver these files, what's the minimum capacity that you would need to beat the FedEx service? (c) Given that you cannot change your current link's capacity but you can compress your files, what is the compressed data size of these files so that they can be transferred in 30 mins? (Assume that the headers cannot be compressed (e.g., used for routing) and would still account for 5% overhead of the compressed data size.) (d) Do you expect that the propagation delay of the link affect your calculations? Explain why or why not
