Wide Area Network Architecture and Strategy

Service Description

ITS supports wide area networking services on behalf of the UC campuses and the UC Office of the President. ITS also serves as the liaison between UC and the Corporation for Education Network Initiatives in California (CENIC).

CENIC supports the CalREN-2 advanced services network, which interconnects all UC campuses, Stanford, USC, Caltech, and the CSU system. CalREN-2 also connects with national research networks such as Abilene, ESNET, and NASA NREN. CalREN-2 offers connectivity to the commercial Internet through its ISP service.

CENIC is planning the Optical Network Infrastructure (ONI), which will replace the original CalREN-2. The first part of ONI should be operational by the end of 2002. It will provide dual one gigabit per second connections to each UC campus.

ITS holds the contracts with CENIC for all CalREN-2 services. Basic services such as backbone connectivity and research network access are largely subsidized on behalf of the campuses. ISP service costs are passed through to the campuses based on their utilization.
