Differentiated IP-net

Related information

For a more detailed technical background, see the technical description in UNINyTT. The project supplements the research network, which works for delivering adequate capacity to our members, and the test network, where server quality is researched.

In addition, a multimedia tool project which looks at tools and pilot services which support differentiating, and the Unitel Project, comes put together with existing video conference solutions over an internal ISDN-based telephone-net for universities and colleges.

International connection

NORDUnet has a 45 Mbps connection to Internet2 in Chicago. Internet2 is built upon a net with differentiated servers called Qbone, where many central American environments participate. This means that Norwegian environments having cooperation projects with American or other Internet2-connected environments, such as Canada, can gain access to this high capacity infrastructure through UNINETT.

Results and reports

• Woohyng Choi: Report on UNINETT Diffserv Test Experiment (Draft 0,2) (html, postscript or text format)

The project's goals

• To offer a prioritizing of traffic for groups/employees at colleges in the internal infrastructure and against UNINETT with priority mechanisms in route
• To start a pilot experiment with use of RSVP in parts of UNINETT in order to serve sound or video conferencing
• To experiment with diffserv-capable routers
• To set up and run a policy-server for RSVP/diffserv (COPS, BB)

The Project's target group

The project shall offer a basic service for other service-oriented projects such as:

• Administrative traffic in colleges
• Pilot users of reservation services
• Multimedia projects
• Internet2 projects

Activities

1. Professor class - Choose strategy and set up prioritizing in routers against colleges, and follow up statistics over use and net quality. Granularity is the whole subnet/porters on college routers.
2. RSVP pilot - set up RSVP in routers for users/pilots. Use filtering and limited archiving of RSVP as access control.
3. Diffserv kernel - Study diffserv technology. Set up test lab and experiment with diffserv-capable routers in the test net. Set up Diffserv over parts of the production net against NORDUnet for eventual Qbone participation.
4. Policy servers: Investigate and acquire and configure implementations of the COPS-protocol in routers and as servers. Set up an experimental server for diffserv's Bandwidth Broker and RSVP. Look at reporting and entry possibilities from the log to the server.
5. Quality surveillance: Investigate possibilities for registration of diffserv and RSVP traffic via RSVP and via routers and present this through existing tools on WWW such as the mapping system.
