22 Jul '98

For the past 12 or so hours, we have been experiencing mediocre response times through MCI's core in Kansas City... has anyone heard of any problems there? I haven't been able to find out anything....(now...where's my multi-homed link request form again???) Danke Kevin Brown Huber & Associates, Inc. Networking Technologies kbrown(a)primelink.com

Operational issue: Mae-east
by dlr＠bungi.com 21 Jul '98

21 Jul '98

According to MFS's network staff, the current mae-east outage (now at 1.5 hours and rising) is a scheduled maintence. According to the on-duty staff, no one was notified. Not even them. Sigh. No ETA of when it will be back up. Dave Rand -- Dave Rand dlr(a)bungi.com http://www.bungi.com

MCI, CA*Net, & ANS routeserver information
by Jason Lixfeld 20 Jul '98

20 Jul '98

I'm looking for a little information on these routeservers. Currently, I am posting all information to the RADB but I am not sure if I should also be sending objects to the aforementioned DBs aswell. My upstreams are UUNet (AS816), SprintLink via Rogers Network Services (AS6463), CA*Net via Bell Global Solutions (AS3804) and soon to be linked to Sprint Canada directly. Is RADB sufficient? If so, why? If not, why? If I need to post objects to other route servers where can I find documentation on where to send the objects (ie: RADB is auto-dbm(a)ra.net and dbm-admin(a)ra.net) Any help would be appreciated. -- Regards, Jason A.

> I'm looking for a little information on these routeservers. I'd suggest re-visiting the IRR web data from the RA/Merit (http://www.merit.edu/radb/docs/irr.html) for another description, check the infopage.mci.net data. The IRR is the collection of all the Routing Registries. If your provider/IP registry has their own routing registry, they will generally expect you to use it, or make provisions with them to pull data from other RRs. All others (generally those of us in the US) go thru the RA's RR. > be sending objects to the aforementioned DBs aswell. My upstreams are > UUNet (AS816), SprintLink via Rogers Network Services (AS6463), CA*Net via > Bell Global Solutions (AS3804) and soon to be linked to Sprint Canada > directly. Check with "Bell Global Solutions" WRT their relation with the CA*Net RR. That's the only potential confusion in what you list. > If I need to post objects to other route servers where can I find > documentation on where to send the objects (ie: RADB is auto-dbm(a)ra.net > and dbm-admin(a)ra.net) Each registry will have their own methods. I'm curious what the ANS/MCI registries will consist of/who they will be used by with all the merges and acquisitions...

Real world broadband backbone architecture. Thanks
by Yu Ning 20 Jul '98

20 Jul '98

Hi friends, I've found here is plenty of traffic in the list, so I hope my question can be answered. Thanks in advance. I'm curretly on a survey of current broadband data network backbone. And I 've heard that many ISP, or US national testbed has adopted ATM as the infastructure to support upper layer IP service, such as UUnet (siad have around 300 ATM switch connected, really?), vBNS, Internet2, Sprint .... But I just can't find detailed discription about their network architecture and method/model to integrated IP with ATM, only some network topology map and service info can be found in their site (except in vBNS, comprehensive archetecture info can be found). Because there are many academic debate about the shortcoming of ATM to support, I just want to see in the real world, why and how the operator/testbed do it. Can any friend give recommend me some URL, or article on this, such as of UUnet or Sprint? Thanks.

Re: NOC communications
by Sean Donelan 18 Jul '98

>Having a different number/email address on your AS than what's on your >domain name might solve some of these problems- it might not. Being much >more aggressive and outwardly unfriendly to people who call the number on >your AS records becomes realistic if you have distinctly declared it for >NOC communications only. Please define "NOC communications only." Are Smurf reports considered NOC communications. How about Spam reports, spoofing addresses, or web pages being down? How about "I can't get through (i.e. I didn't want to wait) to your regular number so I called this one." Fact of the matter is every piece of contact information I have listed in ARIN's database or on a public web page has ended up on a junk mailing/calling list. The contact information which I only give out directly to other NOCs has NEVER been abused. Perhaps we should ask GTE Superpages, UUNET telemarketing, and Bull's Eye Target E-mail why do they use these particular set of contacts for their marketing efforts? >I disagree with your point that NOC-to-NOC communications should ever be >forwarded to a general number, even with adequate training. Is there a Turing test for contact information? There are organizations with extremely good communication operations which provide even better service than calling your favorite NOC engineer directly. Unfortunately they are rare, and as you pointed out, tend to only last as long as the next re-organization plan. >My point exactly - we all have proof that the current system doesn't work >very well. If it doesn't affect the share price, it seems like the management of most major ISPs could care less. This is, was, and always will be a management problem. We can come up with all the clever technical ideas to try to address reasons management gives for not doing something. But until some clever analysist decides this is an issue that can affect earnings, e.g. the Y2000 issue, not much is going to happen. >We already have a central authority that collects two perfectly good points >of information about each AS in North America (supposedly.) Yeah, right. Dear Sprint, Vab is gone. Since you have not updated your contact information in a prompt fashion, your AS numbers will be withdrawn at Midnight. Have a nice day. As far as most provider's are concerned there is no penalty for having out of date or bogus contact information. They view it as just one more added cost, and something that only benefits their competitors and not themselves. That is until they read about themselves on the front-page of the New York Times. Then the managers start yelling at the engineers "Why didn't you tell us it was a problem." Well, I think I've flogged this dead horse enough this time. Maybe we can have this discussion again in another six months. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
