A PBT box gets an ATCA rebirth

Ethos Claims First

2:55 PM -- Ethos Networks Ltd. might be able to claim the first Provider Backbone Bridging - Traffic Engineering (PBB-TE, or PBT) purpose-built switch. That is, the E-80, announced yesterday, was designed from the start with PBB-TE in mind.

Whether that's worth anything more than bragging rights, who knows. CEO Adam Dunsky tells us custom-built gear can better handle certain subtleties of the protocol -- which is believable, but it might not be enough to unseat a Cisco Systems Inc. (Nasdaq: CSCO), Extreme Networks Inc. (Nasdaq: EXTR), or Foundry Networks Inc. (Nasdaq: FDRY) switch.

Ethos seems to realize this, since they're targeting the Tier 2 and 3 carriers. You'll recall that the company's secret sauce involves adding its Dynamic Traffic Engineering (DynTE) to a PBB-TE network, for added quality of service. (See Ethos Claims Ethernet Answers.)

Ethos already had gear ready to sell. But the E-240 turned out to be too big; a 240-Gbit/s core box is overkill for the metro and aggregation jobs PBB-TE is likely to fill. And the E-60 -- the product the E-80 is replacing -- was more a beta product, to hear Ethos tell it, and needed to be more robust for commercial sales. (Why give it a separate name, then?)

So Ethos built up the E-80 from scratch, using an AdvancedTCA (ATCA) chassis as a head start. (Development would have been two or three times more expensive without ATCA, Dunsky says. By the way, did we mention we're preparing a whole day's worth of talk on that subject, in Boston? (See below.)

Ethos did have to make some tweaks to accommodate a card that used more power than expected. Other than that, Dunsky says ATCA worked out just fine.
