San Diego Network Access Point

SDSC Network Storage

Network Transport and Peering

The San Diego Network Access Point (SD-NAP), established in February of 1998, is a neutral network traffic exchange facility that is intended to provide a location for local data network service providers to exchange Internet traffic. The SD-NAP is hosted by the Enterprise Network Services group at the San Diego Supercomputer Center at the University of California, San Diego.

SD-NAP's Primary function is to facilitate efficient interconnection of Internet Protocol transit networks within and to San Diego Local Access and Transport Area, California LATA 6. The service provides shared local and forwarding of internet traffic or shared long haul traffic to educational and research networks like Internet2 or NLR. Colocation of networking equipment in our secured Data Center is also available.

Connections to the SD-NAP are open to all data network service providers and research and educational organizations via membership. We support IP standard protocols and require members to provide a link into your network, a BGP router and a valid AS number. Current SD-NAP users include fiber/circuit providers, ISP's and R&E members such as RCI, The Scripps Research Institute, Cox, SALK, CENIC, ViaNet, AT&T, Freedom Networks, Time Warner, Verizon, Burnham Institute, SDSU, SDCOE, PCH, Zocalo, ESNet, UCSD, and many others.

SDSC Datacenter Colocation users can leverage the SD-NAP peering services to ensure high performance networking between systems in the the SDSC Datacenter and other SD-NAP participants. These peering connections can provide much higher throughput than standard commodity connections.

Primary SD-NAP Benefits

  • High Performance Network Peering The SDSC SD-NAP allows customers to peer with select educational and research networks providing low latency connections that can support high-bandwidth applications. This peering provides shared local routing and forwarding of internet traffic, or shared long haul traffic routing to educational and research networks such as Internet2 and The National Lambda Rail (NLR).
  • Cost and Convenience The SD-NAP provides network peering and equipment colocation at a fraction of the cost of many alternatives, with support and consultation provided by SDSC's Enterprise Network Services (ENS) team. From a single device to multiple racks of equipment, our staff can help you implement the appropriate solution to meet your needs.
  • Physical Security The SD-NAP is hosted at the San Diego Supercomputer Center in a secured and dedicated environment with 24/7/365 monitoring by on site SDSC Operations staff. Access is controlled by biometric identification which enables SD-NAP members to access their equipment as needed.
  • Remote Interface and Performance Monitoring Leveraging multiple network monitoring tools, SD-NAP users can request detailed current and historic interface traffic and utilization reports. This information helps users determine if their current configuration is adequate, and when additional connections may be necessary.
