re: Huawei Strives for Optical Respect

So we have three 400G demos now that hit almost all the same bullet points. Maybe we should just call that the de facto standard. (Kidding.)


Optical burst switching -- aside from this booth and Ireland, am I ever going to see that again?

re: Huawei Strives for Optical Respect

CLOS is  a multi stage switch in which 3 stages ingress,middle and egress can suport non-blocking.  It's not entirely correct to suggest that the term of CLOS is fully non-blocking.  The equipment provide must show there are no blockage or performance errors under maximum switching and processing functions.  I understand what the writer is suggesting but wanted to point out that simply saying CLOS does not mean equipmnet providers get a pass when saying they have a CLOS design and sub-standard processing capabilites or latching performance.  This can also include concerns other then the data, timing or network managment planes.

Rush - Thanks for the clarification on Clos. I basically learned the concept from chip vendors during the 1999/2000 network processor craze, so, yes, my understanding is missing some of that real-world touch.

A cursive look at this year's postdeadline papers shows a large number of papers from Bell Labs.  It's like one third to half of all papers.  I wonder if Bell Labs is still the same as before, the dominating national-monopoly fed research organization with almost unlimited resources, or simply they still occupy the screening committees of the postdeadline papers and tend to select papers from Bell Labs?

Maybe the surge of papers from Huawei reflects the brainy, ex-Nortelian presence. (Such as R Wilcox.) Nortel had that brain trust status in Canada, much like Bell Labs did in the U.S.

That is an ugly looking 16qam constellation. Not impressed. What's the baud rate??

re: Huawei Strives for Optical Respect

Redface -- You know, I'd noticed that too (and it's been the same for years IIRC).  I'd wondered the first part of what you'd mentioned, about Bell Labs just continuing to get resources. Hadn't thought about the second part, but that's an interesting thought.  Alternatively (and charitably), maybe there's a bit of unconscious bias at work when someone sees "Bell Labs" at the top of a paper?

re: Huawei Strives for Optical Respect Nice round-up of Huawei's activities. I wondered what is the de-facto standard after 100G and came to the conclusion there isn't one, not after seeing the details of Ciena's WaveLogic 3 and ALU's PSE.

I remember speaking to Matisse another OBS pioneer vendor that has 2 small deployment. They are defunct since 2010. No one knows if OBS will ever be used in a big time.

I just hope the US Government bans them from selling anything in the US. We certainly don't need there Shit. The Chinese Goverment has already laid virus's within our network systems. Last weekends 60 minutes piece made that pretty evident.
