I've been collecting but not keeping 15 minute states from our site to most US backbones across MAE-East. Its typically under 4% during US night time rising to 4-15% during US day time with the loss generally at the MAE and beyond.
apparently inactive since 2001
9/02: NIMI is undergoing a major restructuring (funded by NSF for the next two years). It remains active, though currently our priority is on working on the restructuring rather than maintaining the current infrastructure.
IEPM was started out for the High Energy Nuclear Physics community worldwide (IEPM manitoring covers about 72 countries) and as such many of the hosts/sites are on Academic & Research networks (e.g. Abilene, CalREN, ESnet, JaNet, GEANT, INFN, APAN, RostelCom, NASA, ...). Thus, it has a rather extensive coverage of the world's academic and hesearch networks. A few of the countries with hosts being monitored do not have centralized A&R nets so commercial network are used to access them. Also some specific .com sites (e.g. WestGroup, DNAI, BellSouth) are monitored, mainly as a left over from a joint project of IEPM and the Cross Industry Working Team (XIWT). We also use IEPM to monitor several ISDN and DSL ISP's in the San Francisco Bay Area to be able to assist SLAC's home user population.
Data only available to participating sites.09/02: "RIPE TTM is alive and well, there's ongoing development on things like IPv6 support, and new machines are being deployed (hopefully at a higher rate than existing machines going unusable :-). The vast majority of the boxes is in Europe, which shouldn't be too surprising given that this is a RIPE NCC project. What's interesting about this project is that it has quite a bit of participation from commercial ISPs, although the majority of hosts are on research networks."
"We currently have some 55 hosts taking data all over the world, 10 more either being installed or repaired, and we are always interested in installing boxes at other sites. The model we use, is that each participating sites pays for its own hardware and a service fee for maintenance of the box and further development by NCC staff.
Our current development plans are:
- An IPv6 version
- Adding bandwidth measurements using Constantinos' pathrate and pathload tools.
- Implementation of the reordering metrics under discussion in the IPPM WG
- CDMA based clocks as an alternative to GPS. If there is a CDMA signal in your area (North America, Korea, Australia), CDMA can provide a timing signal anywhere your mobile phone works, and will thus make installation of a box a lot easier.
- AS level statistics.
