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.
