BigBand and NETGEAR bond on DOCSIS 3.0
This one's a puzzler. Why would a CMTS company and a cable modem company need to cooperate to enact an open industry standard? The whole point of DOCSIS (1.1, 2.0 or 3.0) is to ensure interoperability between devices from different vendors. Maybe I'm missing something.
Update: Mystery solved, they're working togather on DOCSIS 2.0b, which is an intermediate technology to allow the cable MSOs to provide 100 MBPS downstream bandwidth. This will keep them competitive with fiber deployments like Verizon's FiOS, bonded ADSL2+/VDSL2, etc. DOCSIS 3.0 will do this eventually, but compliant equipment won't be ready for at least another two years.
They need to cooperate because 2.0b is not an official DOCSIS standard.
Check out Leslie Ellis' explanation of 2.0b.
