UD Network

The UD network physical layer connects buildings to the campus backbone, to the regional connectors, and to national and international network and computing infrastructures. By authenticating with your UD network ID (UDelNet ID) and password, this infrastructure provides you with a global reach to many network applications.
  • Web servers provide a place for researchers (on and off campus) to gather and build virtual communities (e.g., UD's Sakai portal).
  • Compute servers let you run specialized software and develop scientific programming codes. These hosts can be connected via ssh tunnels, secured by your home directories' public/private keys. These trusted links can be extended to other off-campus Unix systems on which you have a private home directory.
  • Code repositories such as subversion (svn) let you share and develop code with UD and non-UD collaborators.
  • Off-campus access to UD resources is facilitated by UD's network-access services. The license access server lets you use certain licensed software that could otherwise only be used on-campus. The web proxy server allows off-campus access to web-accessible material, such as online Library databases and journals, whose use is restricted by license. And the VPN server provides a secure connection to private or internal UD resources when you are off campus.
  • Federated identity management services provide a network-based mechanism to prove your UD identity to non-UD resource providers. National supercomputing centers, academic research centers, and governmental agencies need to know who you are before providing access to their resources. UD's identity (IdP) server and our InCommon membership facilitates this trusted relationship. UD informs InCommon service providers about our procedures though our InCommon Participant Operational Practices document.

The University's Internet Service Providers (ISP) include the Internet2 Network, the foremost US advanced networking consortium, and commercial providers AboveNet and Cogent Communications

Network and Network Applications

  • Internet2 Network

    Most research and educational organizations typically connect to the Internet2 directly to the Internet2 Network. UD connects indirectly through the MAGPI GigaPop.

  • Internet2 Network connectors

    Research and educational organizations typically connect to the the Internet2 Network through a regional network aggregation point -- a GigaPoP (Gigabit/sec Point of Presence).

  • MAGPI

    UD connects to the Internet2 Network through the MAGPI GigaPop, the Regional Optical Network (RON) that serves the non-profit and Research & Education community in eastern PA, NJ and DE.

  • UD campus network

    A high-level summary of the UD network.

  • Network traffic reports
    • Internet2 backbone

      Graphs of network traffic on Internet2's primary links.

    • UD and its ISPs (on-campus access only)

      Graphs of network traffic between the Chapel St. Computing Center and the commercial internet (AboveNet, Cogent) and Internet2 (via MAGPI).

    • UD's Verizon SES/TLS network (on-campus access only)

      Graphs of network traffic routed through Verizon's Switched Ethernet Services (SES) between the Newark campus and remote campuses and affiliated organizations. SES was formerly named TLS (Transparent LAN Services).

  • Network performance tests
  • Virtual Private Network (VPN)

    Access to UD restricted resources while working off campus.

  • UD Dropbox service

    Use this secure file transfer service for sending and receiving large files (e.g., mail attachments larger than 1 MB) that are 10 GB or smaller.
