- 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.
Network and Network Applications
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).
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.
