Program Plan Intro

Given Data:

In an institutionalized network connected to internet, the average object size (L) is 850,000 bits and that the average request rate from the institution’s browsers to the origin servers is 16 requests per second.

The time to transmit an object of size “L” over a link or rate “R” is “L/R”. (1)

Program Plan Intro

Given Data:

In an institutionalized network connected to internet, the average object size (L) is 850,000 bits and that the average request rate from the institution’s browsers to the origin servers is 16 requests per second.

The time to transmit an object of size “L” over a link or rate “R” is “L/R”. (1)

A cache is installed in the institutional LAN.

Miss rate=0.4

Traffic intensity of the link = (average request rate / average time) (2)

To Find:

Total average response time:
