The Stanford University Network (SUNet) provides redundant and resilient connectivity to commercial Internet and research networks (High Performance Research, HPR) via multiple Internet Service Provider (ISP) connections operating at 10 and 100 Gigabit-per-second (Gb/s) speeds. The SUNet Backbone maintains the aforementioned connectivity via direct peerings with two primary ISP(s): Corporation for Educational Network Initiatives in California (CENIC) and Hurricane Electric (HE).
Current SUNet ISP connectivity is as follows:
• 1 x 10 Gb/s direct Hurricane Electric peering, for commercial Internet services
• 1 x 100 Gb/s direct CENIC peering, for HPR, NREN(s)* and Internet2 services
• 1 x 10 Gb/s direct CENIC peering for secondary HPR, NREN(s) and Internet 2 services
• 2 x 10 Gb/s via CENIC for Digital California (DC) connectivity to education institutions in California and commercial Internet services
Over the next 2 years as part of a broader SUNet Backbone upgrade, each of the aforementioned current 10 Gb/s will be upgraded to 100 Gb/s.
