Design an IP$-$based network that provides the required wired and wireless network services outlined above. Your

answer should concentrate on Layer $2$ & $3$ functionality and must provide a complete view of components and

protocols used. Use the following outline:

$2$

$1.$ Determine the number of WLAN access points required to support the specified number of laptop users in each

campus network $($N$,$ NB$,$ C$),$ taking into account both traffic capacity and coverage. $[$State any additional numerical

assumptions clearly$]$

$2.$ Calculate the link bandwidth required to connect each campus site to the Internet backbone, based on the traffic

assumptions above. If all $100$ university servers are located at NB$,$ estimate the link bandwidth required from N$-$

NB$,$ NB$-$N and C$-$NB$,$ NB$-$C$.[$State any additional numerical assumptions clearly$]$

$3.$ Estimate the number of $64-$port Ethernet switches required for each campus taking into account PC$$s$,$ servers and

wireless AP$$s$.$How many of these Ethernet ports are $100$ Mbps$,$ and how many $1$ Gbps$?[$State any additional

numerical assumptions clearly$]$
