Data & Networking
The ACCESS Networking and Data Transfer Services (NDTS) team provides the CONECTnet ACCESS wide area network and provides efficient and resilient data transfer capability across the ACCESS ecosystem. The team also seeks to identify new data transfer and networking technologies and methodologies for potential introduction into the ACCESS ecosystem.
NDTS focuses primarily on the following areas:
- Network Architecture and Data Transfer Services
- Network performance Metrics
- Cyberinfrastructure Community Engagement
ACCESS wide area network connectivity for RPs is via a Layer3 VPN n (L3VPN) provisioned on Internet2, the national research and education (R&E) network backbone provider. The NDTS team is available to facilitate RP integration with CONECTnet upon request.

Resource provider end-to-end network and data transfer performance consultation
Administration of XSEDE’s high-speed Internet2 overlay network, XSEDEnet, was transitioned to NDTS as the team began working with Internet2 on the XSEDEnet to CONECTnet transition. NDTS agreed to continue with an L3VPN architecture and, in cooperation with Internet2, requested that Internet2 create a new ACCESS OESS workgroup for provisioning the infrastructure, providing a more adaptive and well managed administration approach for CONECTnet. Migration to CONECTnet is in progress with the ACCESS resource providers, and from the view-point of the RPs, the transition is seamless. Support for Globus file transfer continues through the first year of ACCESS operations ending 31-Aug-2023, with documentation and help made available to users for Globus Connect Server 5.4.
