Connectivity to the Internet and Internet2
All off-campus connections to the internet are currently 1-Gbps. There is one primary commercial ISP with a backup connection to CENIC's ISP service. There are two additional connections to the CalREN2 networks run by CENIC. The CENIC High-Performance Research (HPR) network provides high-bandwidth connections among all the California Internet2 participants and to the Abilene network for national Internet2 connectivity. All systems connected to SUNet have access via the HPR network to other institutions which are connected to CalREN2 or Abilene.
The second network run by CENIC is the Digital California (DC) network. This provides internet connectivity to most of the community colleges in California as well as all the campuses of the California State University (CSU) system (note that some CSU campuses also have HPR connectivity). In addition, the DC network provides a connection to each county in California so they can connect their K-12 schools. CENIC also provides internet peering over the DC network. All systems connected to SUNet also have access to any routes receivied from the DC network.
