Problem 5 a) You want to distribute a file of size 10 GB (B=bytes) to 1000 users in a peer-to-peer file distribution approach. Assume that all the connections have 8 Mb/s download rate and a 4 Mb/s upload rate. Approximately, how much time is needed to distribute the file to all the users ? b) Assume you have a 250 KB (B=bytes) file to send to another host, and your connection is a 2 Mbps link. Assuming you can immediately start sending data at the maximum rate (i.e. the link is all yours, no other traffic on the link), how long will it take to transmit the file
