Q$2)$ An Institutional network with access link capacity of $3Mbps$ has a number or access objects from a web servers, the RTT value from the institutional router to any origin server is $1sec$ and the average abject size. is $130$Kbits. whereas, the average request rate from browsers is $20$ request per second.$)$

The institution use $100Mbps$ Ethernet LAN and the queueing delay values varies dependently on the congestion at the access link as depicted in the table below :

$\backslash$table$[[$Access link utilization,Queueing delay $($sec$)],[80\%-90\%,40],[70\%-80\%,10],[60\%-70\%,1],[50\%-60\%,0\mathrm{.}01],[40\%-50\%,0\mathrm{.}001]]$
