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:

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 14 steps — from initial project overview meeting to completion — and the tracker shows the progress of all new connections taking place in each segment.
