Your task is to design and simulate a multi-site network for a small company – including a report on the network design
Scenario: Use the scenario about the ‘Goyal Fabric Company’ used on assignment 1 of this unit (see Appendix 1).
Stage 1: Enter and simulate the Goyal Fabric Company as Company Headquarters (HQ)
Stage 2: Expand the Goyal Fabric Company scenario, explaining your assumptions in a report, adding TWO additional buildings that are branches of the company at remote locations. For example:
Goyal Fabric Company (HQ) – Bournemouth (including Operations and IT Dept)
Design Office – Manchester
Sales Department – London
Goyal Fabric Company has outlined the following guidelines, make your own further assumptions and document them in the report.
- Users at Bournemouth HQ, as described in the original scenario
- IT support at HQ need direct access to the entire network
- About 50 employees in the Manchester Design Office need access to their own local server
- Several wired workstations in the Sales Department at London for ‘hot-desking’
- Access for 50 mobile laptops used by Sales people who visit their office in London
- A server is needed for the Design office, and two for the Sales Department are located at HQ
- The connection to the Internet is via HQ with address 220.127.116.11
- A Web server is needed as in the original scenario
Design and document suitable logical and physical arrangements for the Goyal Fabric Company network:
- Departments should each be on VLANs connected at routers
- Sites should be connected over WAN leased lines (HDLC or PPP), or over Frame Relay.
- Enable MAC address port security on LANs
- Enable authentication on WANs for security
- Bournemouth HQ should have a redundant switched network for resilience
- Default route to the Internet should be connected at HQ (propagated with OSPF to the other sites)
- DHCP, NAT,/PAT and ACLs are needed.
Guidelines on Security Policy
- HTTP access only for all sites to the Internet via HQ
- All other protocols should be denied Internet Access
- All internal PCs need to be able to access the web server
- Firewall needs to allow only established connections for replies to the web server
- IT support at HQ needs full access (ping, HTTP, FTP and telnet) throughout
- ftp and http is permitted from Design workstations to their own server.
- Network design document – no more than 6 pages (Max 2000 words) excluding diagrams and appendices, as HARD COPY.
- Demo in the lab – Using a network simulation tool (e.g. PACKET TRACER), enter your network configuration and simulate it. Packet Tracer file ON A CD.
