The Internet needs *much* better tools than what the NSF RA project offers today (eg the relabeled work done by Ripe) and what they have made public about future plans. (Next days delivery in a millisecond world is not very usefull.) Either the Internet at large develops real tools for a "offline registry" or we have to move this into the exterior routing protocols. -Peter

Sprint has nothing to do with the loops. Gordon -- you as a practioning journalist should know better than to trust "information" of hear-say, particluarly when the source explicitly disclaimed any first-hand knowledge. Sprint customers are informed about scheduled maintenance and outages by means of a special mailing list. --vadim Did this happen on Friday? If so I heard from a directly knowledgeable source that there was a power failure in Dallas that affected the MFS pop there and that MFS had to bring in a truck with generators to get the node operational again. If this is correct wold the looping be really blamable to either UUNET or Sprint? ******************************************************************** Gordon Cook, Editor & Publisher Subscript.: Individ-ascii $85 The COOK Report on Internet -> NREN Non Profit. $150 431 Greenway Ave, Ewing, NJ 08618 Small Corp & Gov't $200 (609) 882-2572 Corporate $350 Internet: cook(a)cookreport.com Corporate.

MAE-east weirdness

Hey folks. I'm working with my friends at National Public Radio. They're having network problems, and I'm not sure the correct people at UUNet to report this anomaly to. The answer NPR got from UUNet was: MFS trouble in Dallas. Does that make sense? any suggestions? thanks in advance. sorry for the interruption. # /usr/local/bin/traceroute npr.org traceroute to npr.org (199.0.132.69), 30 hops max, 40 byte packets 1 router.butterfly.net (199.73.40.1) 7 ms 5 ms 3 ms 2 s0.router.clark.net (199.73.41.254) 12 ms 15 ms 12 ms 3 sl-dc-1-S19-T1.sprintlink.net (144.228.4.1) 19 ms 29 ms 17 ms 4 sl-dc-8-F0/0.sprintlink.net (144.228.20.8) 21 ms 19 ms 17 ms 5 sl-mae-e-H2/0-T3.sprintlink.net (144.228.10.42) 26 ms 18 ms 19 ms 6 Vienna1.VA.Alter.Net (192.41.177.249) 26 ms 297 ms * 7 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 22 ms 31 ms 44 ms 8 Vienna1.VA.Alter.Net (192.41.177.249) 62 ms 87 ms * 9 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 37 ms 36 ms 28 ms 10 Vienna1.VA.Alter.Net (192.41.177.249) 63 ms 83 ms 77 ms 11 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 21 ms 32 ms 27 ms 12 Vienna1.VA.Alter.Net (192.41.177.249) 40 ms 50 ms 68 ms 13 sl-mae-e-F0/0.sprintlink.net (192.41.177.241) 33 ms 19 ms 31 --Dave http://iron.butterfly.net/motodave

Gordon, Karl this might be instructive.

Paper on Prospects for NSF's International Internet Services
by sgoldste＠nsf.gov 05 May '95

05 May '95

I have submitted a paper for INET'95 that might be of interest: <URL:http://inet.nttam.com/HMP/PAPER/178/html/paper.html> ###################################################################### "Future Prospects for NSF's International Connections Program Activities" Steven N. Goldstein <sgoldste(a)nsf.gov> Abstract The National Science Foundation's (NSF) plans for ensuring that the U.S. research and education (R&E) communities will continue to be able to interact over the Internet with colleagues and resources abroad are discussed. NSF has recently transitioned from the custom-provided NSFNET Backbone national transit service for mid-level networks to service provision by several interconnected general purpose ("commercial") Internet service providers. It is anticipated that the plan for international services will be to "ratchet" up the capacity of transoceanic links well beyond the current T1/E1 levels, while minimizing NSF's role in direct service provision, much as NSF has done in the case of domestic service. In addition, NSF's role in facilitating the Internet connectivity of other countries in support of the R&E communities is likely to continue, and demonstration projects in advanced international-scale telecommunications technologies may also be supported. ... At this writing, the precise path to those ends is far from clear. However, a new solicitation for International Internet Services (IIS) has been drafted and is undergoing internal review. Regarding the IIS solicitation, NSF is considering multiple awards in as many as four categories: High-Bandwidth (at least 34 Mbps) Production-Quality Services, International Internet Connectivity Services, High Bandwidth (at least 155 Mbps) Experimental Service & Demonstrations, and Emerging Technology Experimental Service & Demonstrations. The following sections provide a glimpse into NSF's thinking about the new IIS, but it should be understood that these thoughts are preliminary and unofficial. ^^ ^^^^^^ ^^ ^^^^^^^^^^ ^^^^ ^^^^^ ^^^^^^^^ ^^^ ^^^^^^^^^^^ ^^^ ^^^^^^^^^^ ... ###################################################################### There is no way of knowing how long it will take to complete the management reviews and to issue the solicitation, or if the solicitation(s) will emerge in one or in several separate pieces (i.e., subsets of the four categories of services above). We are _targeting_ late May/early June for issuing the solicitation in hopes of being able to make an award, following receipt and review of proposals, by the end of CY1995. cheerz, Steve G. ================================================================ Steven N.
