The California Department of Transportation District 12 (Caltrans D12) utilizes the latest in IP Ethernet switching technology. The current ITS IP Network is scalable and provides an end-to end solution. The Core network is designed into a Layer-3 environment utilizing the best practice design: Core, Distribution, and Access layers. The network has provisions for redundancies and quality of service. The network is deployed around two-Dual Core Cisco 6506-E Switches, which connects to seven Cisco 4507R switch used for distribution layer and several hundred IE-3000 switches at the access layer. The Core to Distribution links are 10 GB/s links while the Distribution to Access links are 100 MB/s links with a future path to a 1GB/s access layer links.
