About the CUIT Network
CUIT maintains Columbia's commodity INTERNET connections, which include:
- 1 Gbps connection via Level 3
- 5 Gbps connection via Cogent
- 100 Mbps connection via RCN (for RCN residential cable modem customers)
Columbia's research and education network connections include:
- NYSERNet NYC and statewide regional optical network ("dark fiber")
- 1 Gbps connection to NYSERNet's IP network and from there to Internet2 and National Lambda Rail (NLR) packet net
- 1 Gbps connection to the US Large Hadron Collider Network (USLHCNET) providing connectivity to CERN
- Potential for much higher bandwidth and advanced networking connectivity as needed for specific research needs such as dedicated "waves" or "lambdas" and international dynamic circuit networks
CUIT participates in various aspects of the Internet2 initiative, including IP multicast, IPv6, IP telephony, and IP videoconferencing. Please view our Internet2 project page for more details.
CUIT collects and analyzes in- and out-bound Internet traffic in order to gain greater configurability and performance. Tools used to perform this analysis include graph generator and flow collection modules created by our own staff as CUIT open source software projects.
To deal with the problems of abuse of Peer-to-Peer file sharing programs without unduly invading our users' privacy, we implemented an automatic rate-limiting system for users based on a usage quota.
