tiers. A measurement tool.
by Mark Kent 18 Jul '97

18 Jul '97

Clearly the definition of tiers varies over time. I think that the tools needed to "measure" the current tier-ness of providers are: a) a full bgp table (not just a full route table... if net FOO appears behind AS3561, AS1239 and AS1 then you want all three entries). b) a suitably large group of companies whose net access depends on how you extract a route table from the full bgp table c) a stopwatch d) a phone The procedure is basically to eliminate an AS from getting in the route table and timing how fast the phone rings. Then you just need a scale, something like this 0 - 2 minutes: Tier 1 2 - 10 minutes: Tier 2 etc. In some cases you can replace the stopwatch with a calendar. You can flesh out this methodology with extras like frequency of calls, duration of calls, language used in the calls, whether you are threatened or not, whether your family is threatened, etc. This technique has been used by some service providers by way of their peering strategy. -mark

Correct you are! Having spent 7 years of my career doing large OSP (OSP in this case is Outside Plant) installations around the country including direct buried, ducted and aerial I can confirm that these techniques are routinely employed.

Large numbers of local multi-pair trunking cables are pressurized with nitrogen, and they put pressure drop alarms on them, so they know if one takes a hit. Cheers, -- jra -- Jay R.

BHTC - Back-Hoe Technology Certification There may be a need for all back-hoe aoperators to obtain a telco certification. Perhaps, these back-hoe unions could then sub-contract through telco agencies...picture this! "Hello, AT&T back-hoe. How can I help you?" or "Worry no-mo with UUnet Back-Hoe!"

One of the interesting things about the startup of Wiltel was pulling fiber through decommisioned gas pipelines; not only do you get a 1/4" steel backhoe fade margin, but you get scary yellow signs that say "DANGER: HIGH PRESSURE NATURAL GAS LINE"; cut a piece of innerduct and your boss yells at you. Bust a gas pipeline and they can bury what's left of the offender in a thimble - if they can find it.

Actually only a percentage +/-9% of the old WilTel network is still in pipe. A great sales tool though. The ring concept is noble one. Most carriers are trying their hardest to build those systems. What has prevented it so far is order backlog! There are so many pending orders for additional network that the new fiber builds are going in as linear SONET OC-48 and OC-192 where available. Seems that they can't afford to part with the precious overhead that the RINGS require. Dan L Dale Sr. Sales Engineer Exodus Communications, Inc. (formerly of MCI and WorldCom) -----Original Message----- From: Owen DeLong [SMTP:owen@DeLong.SJ.CA.US] Subject: Re: DC fiber cut: field report The thing that doesn't make sense to me in all of this is that SONET is supposed to be built as RINGS. With a Service side and a Protect side to each switch. BIFF should, in theory, only take out one or the other, but not both. WHY, with what we pay these carriers every month, do they not divergent-path route these critical wide-area links so that this isn't fatal? > > Anyone from MFS/WilTel/WorldCom/UUNET/AlterNet/whoever-else-they-buy-but- still-don't-fix-what-they-have care to comment?
