Consider the figure below, in which a single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link.

Suppose that the packet length is L= 16000 bits, and that the link transmission rate along the link to router on the right is R = 10 Mbps

What is the

maximum number of packets per second that can be transmitted by the link?

An institution has a 1.54 Mbps

access link to the public Internet and a 1 Gbps LAN. A local web cache is

implemented with a cache hit rate of 0.5, meaning 50% of requests are served

locally with negligible delay. The remaining 50% of requests must be retrieved

from origin servers over the Internet. The average data rate to browsers per

second is 1.80 Mbps.

What is the new access link

utilisation after introducing caching? Please give your answer as a percentage.

non-persistent HTTP, where every image, script, and ad causes a new TCP

connection to be opened and closed. This increases the round-trip time (RTT)

and causes significant delays. The development team is now considering
