Networking in National insurance company -- 3
Budget: $30 – $250 USD
Design an Enterprise Network including LAN, WAN, Wireless, and Cloud components
You should consider the following design points:
Top-down design approach should be used, start from Applications down to Network, Data Link and Media layers:
Explain in detail your choice of applications, routing protocols, switching mechanism, and media used
Explain in detail your addressing and naming choices
Follow the life cycle of a network design process including:
Phase 1 – Identifying Customer Needs/Goals
Phase 2 – Logical Network Design
Phase 3 – Physical Network Design
Phase 4 – Testing/Optimizing/Documenting
WAN should have three hierarchical layers: Core, Distribution, and Access networks
LAN should be established in each building by collecting traffic from each floor (wiring closet), passing down to the server room
Each floor should have a gateway to the exit point of the building, and each building has gateway to the public network
Physical and logical topologies of both LAN and WAN
Service Provider (ISP) and enterprise parts of the network
Technologies and devices used
Traffic analysis
Use of Cloud, private or public (To Cloud or not To Cloud)
Your Enterprise should include:
WAN:
Several locations across the nation
At least 1-2 major campus networks
At least 1-2 small branch office networks
At least one remote branch office
At least one international branch office
Several employees that work from home
Use at least two ISPs for redundancy, load balancing, and backup
Use of routing protocols, OSPF, RIP, and/or EIGRP
Use of switching technologies, Ethernet (10/100/1000 Mbps), VLANs, Frame Relay
WAN security measures: VLANS, Access lists on the routers, routing and switching security measure
LAN:
Each campus should have several buildings
Each building should have several floors
Required Servers on each site and for the entire enterprise: Mail, Web, File, Database, Application, DNS, DHCP, Storage Area
LAN security measures: AAA servers, firewalls, Authentication, Encryption
WAN security, VPN, Encryption,
DMZ security: Proxy, Firewall servers. Mail and Web servers should be here
Use of Cloud environment, public or private
Wireless:
You could include one or more wireless technology to your project in order to improve your enterprise network accessibility. Typical wireless technologies in an enterprise are WiFi, WiMAX, Cellular systems (LTE), Bluetooth, ZigBee, Wireless Local Loop (WLL), etc.
Cloud Computing:
You could consider to use a cloud system (either public or private) to enhance your enterprise network capability. Cloud environment could be deployed for your network and cloud services could be used for both your enterprise employee and/or for your customers. Based on your technical evaluation decide whether to go with the cloud or not, and if you decide to use cloud, which one do you prefer: private or public, and Why ?
Example:
www.MyEnterprise.com
Locations:
2 major locations: head office (HO) and manufacturing in Dallas and Minneapolis
2 local branch offices in New Haven and Toronto (International sales)
Network Applications used on all sites: e-mail and browsing, VoIP and video conferencing, video streaming, distant learning, online ordering
Dallas HO has three big campuses in different locations across the city, each campus includes several buildings
Departments: Management, business, and marketing
Users: 500, 5000, and 10000 employees
Minneapolis has 2 campuses: Engineering and R&D, each campus with multiple buildings
5000 employees on each sites
NH: has 200 support staff
Toronto: 500 sales staff
500 sales agents across the country in different locations
