re: Adtran Buys Luminous Emberschipsischips sez: 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?)

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.
re: Adtran Buys Luminous EmbersA 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.
re: Adtran Buys Luminous EmbersWhile 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 EmbersAgreed, 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 EmbersThe 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.
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.
