Please answer and not copy answers from the internet cause i need some understading : An educational institution has an access network whose operating parameters are as follows: access link to originating servers’ rate: 15.4 Mbps RTT from institutional router to server: 2 sec Web object size: 100K bits Average request rate from browsers to origin servers: 150/sec average data rate to browsers: 45.0 Mbps Institutional access network speed: 1Gbps. 3.1. You are requested to provide the performance of the institutional access network in terms of • LAN utilization • Access link utilization • End-to-end delay from the access network to the origin servers. Note: Assume that the requests from the web client to the originating web servers are of the order of 2GB of data on average. 3.2. Assuming that the institution would like to install a web cache in its access network with a cache hit rate is 0.65, you are asked to recompute the new performance of the access network in terms of: 3.2.1. LAN utilization 3.2.2. Access link utilization 3.2.3. End-to-end delay

An educational institution has an access network whose operating parameters are as follows:
access link to originating servers’ rate: 15.4 Mbps
RTT from institutional router to server: 2 sec
Web object size: 100K bits
Average request rate from browsers to origin servers: 150/sec average data rate to browsers: 45.0 Mbps
Institutional access network speed: 1Gbps.
3.1. You are requested to provide the performance of the institutional access network in terms of
• LAN utilization
• Access link utilization
• End-to-end delay from the access network to the origin servers.
Note: Assume that the requests from the web client to the originating web servers are of the order of 2GB of data on average.
3.2. Assuming that the institution would like to install a web cache in its access network with a cache hit rate is 0.65, you are asked to recompute the new performance of the access network in terms of:
3.2.1. LAN utilization
3.2.2. Access link utilization
3.2.3. End-to-end delay
