Networks & Connectivity

Backbone Network Connectivity

Upgrade your network with a connection to the campus backbone, for high-performance access to UCLA computing resources, the Internet and Internet2.

The UCLA Campus Backbone Network (CBN) is a high performance "network of networks" that interconnects the UCLA community, providing access to departmental computing resources, University of California system resources, and regional, national, and international networks. The network enables an individual at a single workstation to access many services on a variety of computers and numerous networks both on-and off-campus, including Internet access at speeds up to 10Gbps. The network is designed to be highly reliable and operational 24 hours a day, 365 days a year.

The UCLA campus backbone network is also connected to CalREN, the California Research and Education Network, run by CENIC, the Corporation for Education Network Initiatives in California. CENIC is a nonprofit organization that advances education and research statewide by providing a world-class network essential for innovation, collaboration, and economic growth. The CalREN backbone includes roughly 8,000 miles of CENIC-owned and managed fiber, last-mile fiber, and hundreds of optical components. There are two networks that operate over CalREN:

  • CalREN-DC: CENIC's Digital California network, provides high-quality network services for students/teachers/staff and for faculty, researchers, and staff at education institutions. Connectivity to the commercial Internet is provided by this tier.  
  • CalREN-HPR: CENIC's High-Performance Research network, provides leading-edge services for large-application users at CENIC Associates sites. Connectivity to Internet2 is provided by this network tier.

Getting Started

Campus backbone connections are primarily done for departments who have their own IT staff, and provided by Managed Network Services, the unit of IT Services that manages all network connection points from the campus backbone. If you’d like to connect your department to the campus backbone, please contact IT Services at webcenter.it.ucla.edu. Administrative and technical staff will gather your network design, compatibility, timing and cabling needs to ensure they can be met.

If your research requires connectivity to the campus backbone network, please contact your department’s Network Coordinator. To find your Network Coordinator, visit our Network Coordinators list.
