Arthur T Knackerbracket has found the following story:
Cisco has dropped an open reference design for DOCSIS silicon into the CableLabs standards body.
The group has been working on Full Duplex DOCSIS for some time, and in February announced that the gigabit up / gigabit down effort was worth pursuing.
Switchzilla has been pursuing it, and has handed over its design for a digital echo canceller that integrates with DOCSIS Cable Modem Termination System (CMTS) standards (CMTS specifications cover the cable hubs on the provider side of the network).
Cisco says the echo canceller will work for upstream carrier frequencies from 200 MHz (1.7 Gbps) all the way to 1.2 GHz (for a 10 Gbps upstream channel).
While Cisco hasn't detailed the specifics of the echo cancellation reference design, by providing it royalty-free through CableLabs the company hopes to give the Full Duplex effort a kick along.
The current DOCSIS 3.1 spec supports 10 Gbps down but a maximum of only 1 Gbps upstream.
The CableLabs feasibility study in February was followed by a Nokia demonstration in May. Nokia's Bell Labs showed that a point-to-point hybrid fibre-coax network can hit 10 Gbps symmetrical speeds.

Just the other day I saw some research showing that the world's packet reserves are already running dangerously low. Just look at what happened when IPv4 started having resource contention: various world powers set up shadow wars in Central Africa to push out indigenous peoples so they can exploit the precious IP reserves rumored to exist there. Do you really think this stuff is just a coincidence?
Now when it comes to the world's data packet resources, it looks like we have at least a few years before things really start going south. But with recent "advancements" promising ever faster consumption of this limited, precious resource that powers nearly every aspect of society, we need to start asking ourselves if it is responsible for big corporations such as Cisco to release methods for devouring packets at unprecedented rates. At least a few of the larger companies in this space (Verizon and Comcast are two shining examples I can think of) are responsible enough to throttle and cap the bandwidth they serve to the greedy masses.
Network packets aren't a scarce resource, you say? Look, I've stared into the gaping maw of a few data mining operations and I can tell you packet scarcity is a very real issue, to say nothing of the environmental effects of some of the newer, unregulated techniques of deep packet extraction. Mainstream media, for whatever reason, doesn't report on this stuff. I dare you to pull back the veil... travel to some of the more remote regions of China or Siberia where these data mining operations have scorched the earth and destroyed the lives of the workers there. Or indeed, refer to some of the data mines run by TLAs state-side.
Even as I write this post, I feel guilt for using so many network bytes... but I suppose it is a necessary evil so that I can try to get word out about this impending crisis. Many will not know until it is too late, and we've run out of high quality network packets. Farmers in North Korea are already turning to decades-old discarded AppleTalk packets, crudely modified to serve as IP packets. Some sources report packet loss in those regions as high as 70-80%! Similar reports are coming out of areas of China, where state-run mines have run out of quality packet ore. They continue to ship packets of ever-decreasing quality, while their government says everything is just fine... imagine if that happens here in the great USofA!
I implore you, dear reader, turn off javascript, don't load images, and for the love of our way of life, enable Binge On if you're a T-Mobile subscriber. Humanity itself is at stake!

As a concrete example, I have read about people going to Antarctica for the express purpose of extracting data from the polar ice cap. That data is, presumably, then packetized and sent off to satisfy a tiny portion of society's hunger for data. This deep data from ice caps is irreplaceable!
