Consider a small sized company that is interested in setting upa network for their business. The company has a total of 350employees: 250 employees are located on five floors of the HQbuilding based in Chicago, and the other 100 employees are locatedon two floors in a building in Seattle. The two sites are connectedusing a WAN link. Each employee has a desktop and an IP phone ontheir desk. In each office (building), there are four servers, thefirst for engineering development, the second for manufacturing,the third for the company’s external website, and the fourth formanagement, sales, marketing, and personnel databases. The serversin the Seattle office are backup servers for the servers in theChicago HQ; if any server fails in HQ, its functionality fails overto the corresponding server in Seattle. There should be three LANs,one for the engineering department, one for manufacturingdepartment, and one for marketing and administration. Theengineering department has 200 employees in total (150 in Chicago,50 in Seattle), and its LAN hosts the engineering developmentserver. The manufacturing department has 100 employees in total (70HQ, 30 Seattle), and its LAN hosts the manufacturing server. Thelast LAN hosts the remaining two servers, and has 30 employees inChicago and 20 employees in Seattle. All these LANs are wired LANs.Additionally, the Chicago office has a guest WLAN that can serve upto 63 connections, while the Seattle office has a guest WLAN whichserves up to 30 connections. The company has been assigned the IPaddress range 216.244.168.0 to 216.244.175.255. The IP addresses216.244.175.254 and 216.244.175.253 are reserved for the two endpoints of the WAN link.
1. Describe the networking requirements for this company as aNetwork Administrator.
2. Design a network and specify the IP address range for eachLAN/WLAN.
3. Suppose an engineer in HQ opens a telnet session with theengineering development server (in HQ). Describe in detail thetraffic flow.
4. Suppose an engineer in HQ pings the manufacturing server in themanufacturing LAN in HQ. Describe in detail the traffic flow.
5. Suppose an engineer in HQ pings the manufacturing server in themanufacturing LAN in Seattle. Describe in detail the trafficflow.
6. Write down the routing table of the router to which theengineering LAN is connected to in HQ. The routing information inthis table should ensure network-wide IP connectivity between anypair of hosts. The table should include these fields: destinationnetwork address, netmask, next hop address/outgoing interface, hopcount to destination (including the destination subnet).
