New Equipment - Anybody try'em?
by Douglas Jardine 10 Aug '97

Hi, Are there Net operators of large corporations or ISPs who have had a chance to evaluate new network equipment released over the last year? I know from previous postings that ISPs have started using the GRF with reasonable success. Anybody out these using Ipsilons IP switches? The way I understand these, they have (fast)ethernet and ATM (at OC-3 rates) ports available and can do RIP and OSPF making them suitable for Interior Routing. I am not sure if they support BGP or for that matter if the IP switch concept would scale (in terns of VCIs needed) to full fledged ISP load. Also is anybody out there trying to build backbones out of all the new Gigabit ethernet gear being announced? At first glance, it seems to me that these layer 2/3 products are capable of Interior routing, besides switching at mosnstrous speed. Would greatly appreciate any first hand experience. TIA. -dj ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Backup Power Schemes
by Eric Osborne 09 Aug '97

OK, let's see if we can turn this thread from BBN-bashing into something a bit more constructive. I've seen several posts in the past few days concerning optimal power backup strategies, both short and long term (battery, diesel, and/or nuclear). Anybody out there care to share your strategies? eric

>As more and more companies come to rely on the Internet like they rely on >the PSTN, we will be expected to have bomb-resistant networks. (not >bomb-proof, mind you), and we will have to be compensated for this level >of redundancy. No. People who need an extremely high level of fault taulerance can build it into their own network without every link in the public network maintaining that same level. You already have self-healing SONET, at an added cost, I don't think we'll need to step beyond that for normal commercial usage. Iraq did not have such a high level of communications infrastructure, yet we could not block their access to their TCP/IP network nor the Internet. There is a big difference between the needs and requirements of fault taulerant uninterupted service and catastrophe/emergency service. The latter you can get by POTS, radio, sattelite, etc, and combinations there of. Hell, a big APC and 19" sattelite dish can go along way for emergency service. On a side note, remember a number of years ago when they (US) where selling decommisioned nuclear silo bases (bomb /proof/, 300+ feet underground). That could make an awesome co-lo facility ;-).

Just a word

Ummm to clear something up, BBN's (GTE) NOC did not go down during the power loss to the Cambridge area. We are fed directly through a power transform station that is less then 1/4 mile from the NOC. What did go down was the POP which is not located at the same place as the NOC.

wb8foz(a)nrk.com said: > Gas Turbine. Not very fuel-efficient, but much less routine maint > than Diesels. Also smaller. > variations: Propane fuel, Natural Gas For those of you who have never had the pleasure of working with turbines, they are not something you would want to be near humans who still want their hearing. At about .5MW load, they have a marked similarity to a jet plane taking off (no surprise.) Fine for out of the way places or low class commercial areas, but probably not something that would want to be on a slab in downtown San Jose or Palo Alto. Diesel is much quieter and easier to muffle. But if you need a lot of power, natural gas turbines get really big, and the odds of a turbine starting are better. I like turbines, but almost never find a place to put them. (then again, I still like MG sets.) jerry

CO equipment is designed for 48v for many reasons. It's also designed to deal with concrete floors, inefficient HVAC, dust, etc. Unfortunately, a modern megapop consists of a lot of interesting equipment that doesn't come in 48v DC versions. Alpha 8400s, Large SGIs, and server like things (yeah, I know, there are companies who make retrofit kits for some of them, but they're not standard). The real issue is planning... MAE E and MAE W *weren't* designed for the things that MFS is stuffing in them. Most of the other pops have the same problem. It *is* possible to design a facility that is run off an inverter permanently, which is connected to a UPS, which is connected to utility power, and to a diesel generator, which *is* able to cope with extended failures of _utility power_ without affecting the equipment (routers, switches, modems, and servers) at all. And I think the modern facilities will be built that way. 4-12 hours of batteries is serious when you're talking about a large hosting facility. Sprint/MCI may be laughing, but they're haveing to scramble to build POPs capable of supporting server farms because they can't do that now. And another thing, batteries or not, *no-one* can easily survive a catastrophic event like a fire, an explosion, or even the wires that got eaten in BBNs Stanford center last year. (Didn't AT&T hose most of Chicago's loop area a few years ago, for more than a *week*?) I bet they had DC in their vault. Didn't help them much...

The BBN Cambridge POP is "down and out" after a nearby manhole fire cut power to the building housing the POP. -Where is the generator backup?
