Network Infrastructure

Our network architecture utilizes the Enterprise routing and switching engines from Juniper and Cisco. We utilize Juniper M20 routers as border routers, Cisco 6500 series switches in our distribution layer and Cisco 6500 switches in our aggregation layers, and Cisco 3500 and 2900 series switches at the customer layer. Our network is fully meshed and redundant with 10 backbone providers. Our current network consists of UUNet (GigE), Sprint (GigE), Level 3 (GigE), Global Crossing (GigE), Verio (GigE), AT&T (GigE), Time Warner (GigE), Allegiance Telecom (2 x GigE), Broadwing (GigE) and AboveNet (2 x GigE).
