CENIC's
California Research and Education Network (CalREN)
consists of a CENIC-operated fiber optic backbone,
to which schools and other institutions in all 58
of California's counties connect via fiber-optic
cable or leased circuits obtained from telecom
carriers. Currently, the CalREN backbone consists
of 2,700 miles of CENIC-owned and managed fiber,
plus last-mile fiber. This network is HOT! The
backbone can support up to forty 10-Gigabit
wavelengths of transport bandwidth on a single
pair of fiber. Additional network components
include:
-
472 routers and 81 switches,
-
51 optical components, and
-
300 managed telco circuits.
Dedicating transport wavelengths for different
purposes, CalREN operates 3 distinct networks to
meet the diverse needs of California’s
sophisticated educational institution users:
CalREN-XD:
The experimental and developmental network
supports bleeding-edge services for researchers at
sites like the San Diego Supercomputer Center, the
U.C. Institutes for Science and Innovation,
Caltech’s Center for Advanced Computing Research
and Jet Propulsion Laboratory, USC’s Information
Sciences Institute, the Stanford Linear
Accelerator Center and other major network
research entities.
CalREN-HPR:
The high-performance research network provides
leading-edge services for large-application users.
CalREN-HPR connects to the
Internet2 Abilene network at 10 gigabits per
second (Gbps).
CalREN-DC:
The Digital California network provides very
high-quality network services for K-20 students,
teachers and staff at California’s higher
education institutions and K-12 schools. The DC
backbone speed is 10 Gbps. |
