Telco wise, BBN does have a nice dirverse system. Their MCI T-3 is on a microwave that goes to Palo Alto, where it drops off to MCI's bay area fiber ring between San Jose to San Francisco.

Their HUB is connected by one microwaved DS-3? This is not good. Granted,

This DS3 is one of 4 private interconnect BBN has to MCI. I don't think there's anything wrong with it's current provisioning given that their other backbone DS3 have diverse routing.. Please correct me if I've missed something. -dorian rk, or 2) Was not available ... See my previous comments about rusty generators.

Granted, most DS-3 microwave radios have hot standby radios, muldems ect. on each end but, they are always ripe for outage due to interference or path fade. I can see the microwave as a segment of a SONET OC-3 link, only if the other side is fiber.

Some of their backbone T-3's come into a Pac Bell OC-48, which has an entirely seperate protection path into Stanford itself (Stanford alltogether has two Pac Bell OC-48's, with a third one planned!). Another fiber path belongs to MFS for more dirversity. So on that level, they have their act together.

This is good.. How many of BBN's peer connection run over the SONET ring? Regards Patrick J. Chicas Email: pjc@unix.off-road.com URL: http://www.Off-Road.com -------------------------------- The Off-Road Center of The 'Net!
