ider downloading a file of size F bits from a Perver S to a client C. The client has an access link with transmission bit rate R, = R bit/s to the backbone of the Internet, while the server has access transmission bit rate Rs = 2R. We model the backbone of the Internet with two links with transmission bit rates R1 = 5R and R2 = 10R. Thus, there are total of four links in the considered network. Th
