Network Overview

CENIC's California Research and Education Network (CalREN) is a multitiered, advanced network-services fabric serving the majority of research and education institutions in the state. The CalREN backbone includes roughly 8,000 miles of CENIC-owned and managed fiber, last-mile fiber, and hundreds of optical components.

The backbone has three components: optical (Layer 1), Ethernet (Layer 2), and routing (Layer 3). CENIC engineers perform regular upgrades to all three layers, with recent upgrades including:

--Core backbone: upgrade from 4x10GE to 100GE (spring 2014)

--Los Angeles to San Diego to Riverside region: upgrade of the Layer-3 network from 4x10GE to 100GE (fall 2015)

--Los Angeles: upgrade of 10GE access port capacity (fall 2015)

--Central Valley region: upgrade of the layer-3 network from 10GE to 100GE (spring 2016)

--Los Angeles: additional 10GE access port capacity upgrades (summer 2016)

--Downtown Sacramento hub site: upgrade to 4x10GE backbone bandwidth (summer 2016)

--Oakland: upgrade of 10GE access port capacity (early fall 2016)

--Los Angeles: upgrade of 1GE access port capacity (fall 2016)

--Sunnyvale: upgrade of 10GE access port capacity (fall 2016)

--Oakland: additional 10GE access port capacity upgrades (late fall 2016)

CENIC has a Connection Tracker that displays the status of current projects among three of the CENIC segments (with others to follow): K–12 schools, public libraries, and community colleges. Each connection to CalREN requires fourteen steps—from initial project overview meeting to completion—and the tracker shows the progress of all new connections taking place within each segment.
