Consider the following scenario, in which a Web
browser (lower) connects to a web server (above).
There is also a local web cache in the bowser's access
network. In this question, we will ignore browser
caching (so make sure you understand the difference
between a browser cache and a web cache). In this
question, we want to focus on the utilization of the
100 Mbps access link between the two networks.

Suppose that each requested object is 100Mbps, and
that 90 HTTP requests per second are being made to
to origin servers from the clients in the access
network. Suppose that 80% of the requested objects
by the client are found in the local web cache. What is
the utilization of the access link?
