Advantages / Disadvantages

Implementation Time

Minimum Anticipated Network Life Span: 7-10 years

Design Considerations:

1000% LAN Growth

100% WAN Growth

Utilize access lists locally and globally• Double Firewall

Every administrative node gains access to network through user passwords

Access to Internet, Administration LAN, and WAN requires user password

Access outside LAN is through the District Office Outside access to LAN prohibited through access lists
