The push to make technology work not just faster but more efficiently too is a new enough concept that its ramifications are still being understood. The more time is spent thinking about it, the more places waste and inefficiency are identified and targeted.

Take Ethernet. You probably hadn't thought twice about that gray Ethernet cable on the floor, but an IEEE task force has been staring at it for well over a year, trying to make the darn thing more efficient.

The goals of the IEEE 802.3az task force are pretty straightforward: define a mechanism to reduce power consumption during periods of low link utilization and a protocol to coordinate transitions to or from a lower level of power consumption. It'll work only on new hardware, of course, but that hardware should be fully backward-compatible.

Parsing through some of the publicly available documents yields an awful lot of complex circuit diagrams ... and a bit of interesting information. According to a presentation by Hossein Sedarat of semiconductor manufacturer Aquantia, "channel staggering" in combination with a few other technologies may lead to a 75% power savings. That's in 10GBase-T, a wicked fast form of Ethernet. But it's not unreasonable to guess that ordinary 100MB Ethernet could see similar savings.

The task force hopes to finish a draft specification this month, which will go through an approval process next year. The final spec won't be released until March of 2010. To learn more, I talked with a few members of the task force--their comments after the jump!
