Adtran Buys Luminous Embers

At least a piece of packet transport vendor Luminous Networks has found a home at Adtran Inc. (Nasdaq: ADTN)

Sources say Adtran has completed an acquisition of Luminous assets. No pricing information was available at press time. Luminous's Website even redirected to Adtran's for a brief time last week, although that situation has since been changed.

Adtran wouldn't comment when asked about the deal.

Luminous declared its shutdown at the end of last year. (See (Luminous Loses Its Luster.) The company reportedly was wrapping up affairs with a skeleton crew, operating out of an office in the charming Silicon Valley suburb of Campbell, Calif. Could be true -- there's a phone number for "Luminous Networks" in Campbell, but it's been disconnected.

Luminous's closing ended a seven-year, $183 million quest to bring Resilient Packet Ring Technology to the telecom masses. Rival RPR firm Lantern fared a little better, getting acquired by C-COR Corp. (Nasdaq: CCBL), but the ending wasn't much happier. Early this year, C-COR shut down the Sunnyvale, Calif., facility that was Lantern's home, although not all the employees were laid off immediately. (See C-COR Extinguishes Lantern.)

Not that it's all sunshine and rainbows at Adtran. The company's stock got pummeled earlier this month when Adtran lowered its first-quarter guidance. (See Adtran Lowers Guidance.)

Who's left in RPR? Well, there's always Cisco Systems Inc. (Nasdaq: CSCO) and Nortel Networks Ltd. , which were shipping similar technologies before the Institute of Electrical and Electronics Engineers Inc. (IEEE) 802.17 standard formalized RPR. Corrigent Systems Inc. is still kicking as well, and the stock of its parent, Orckit Communications Ltd. (Nasdaq: ORCT), did well in calendar 2005 despite some stomach-turning dips. (See Orckit, the Killer Stock.)

re: Adtran Buys Luminous Embers Where did all the new products go?

All I see these days from Trade Shows are new customers and new acquistions. Gone are the Great New Product PRs.

Doesn't bode well for the industry. We need to be driving forward with product enhancements.

re: Adtran Buys Luminous Embers ...long live Ethernet over SONET!

From the floor of TelecomNext this week, RPR was deader than a doornail.

Ah, but what about the cable market? Weren't they supposedly big on RPR? Maybe the cable National Show is the place to look. (Or maybe i'm just kidding myself?)

re: Adtran Buys Luminous Embers Cable has gone the cheap DWDM/GigE route.

Craig, you're kidding yourself. Cisco made such a bad name for it's RPR, there was no space for RPR in any market, including cable.

Cable's not buying RPR. Look at the signs.

re: Adtran Buys Luminous Embers A very high ranking exec at a very well known carrier told me very recently that he wished there were a vendor who made packet based IP rings which were optimized for video, not wasteful for high speed data, able to do voice without wasteful circuit em, had QoS that worked, etc., etc... and he didn't want an MPLS or EoS system!

And I kept quiet. Kept my mouth shut. Did not mention RPR. Or Luminous. Or Lantern. Or Corrigent. (who, by the way, will die once KDDI runs out - Yeah, I'm real positive tonight.). Or C-COR, or Adtran. Poor Adtran. They have no idea what they're getting into, do they! ROTFL!

Let the dead sleep peacefully and move on with your lives.

I'm sick and tired of executives who don't know their s**t anyways - they couldn't see it when these startups danced in front of them with products, and will now be forced to buy mediocre products from Cisco/NT.

Mediocrity deserves mediocrity.

Yeah, sure, RPR is dead. I'll drink to it.

re: Adtran Buys Luminous Embers While it is a little more complex MPLS, with Fast Reroute, can also provide a ring or multiple interconnected rings or various forms of mesh networks. It enables more grandular prioritized (QoS) streams (LSP). If you use one of those (more expensive) edge routers that has MPLS with DPI this makes a lot of sense.

But if you want 'cheap', or almost 'carrier class' there are several approaches that were discussed in 3/16 'Ethernet Access Rings' archived Webinars.

re: Adtran Buys Luminous Embers Agreed, RPR over SONET is too expensive for the Metro Access where there is plenty of fiber. For core applications however, which have to use SONET leased lines, RPR is a very good choice providing 50ms and QoS/fairness.

Cisco and NT are doing pretty well in selling RPR. What about Alcatel and Huawei, have they got any products out already? Rumours are that we'll see RPR being built into DSLAMs in 2006.

re: Adtran Buys Luminous Embers The problem with RPR is lack of a good inexpensive RPR chip for Gig-E and 10Gig-E. It's nonsense to talk about running it over SONET since RPR is just a poor man's SONET.

I'm not quite willing to declare RPR dead but lack of an inexpensive implementation will certainly kill it.
