IEEE Approves 40Gb/s and 100Gb/s Standards

By Michael Marr

Back in June, the IEEE finally approved the 802.3ba standard. The standard began to be investigated back in mid-2006, and has finally culminated in the new 802.3 standard. This is the first time two connection speeds have been specified in one standard. The previously fastest IEEE standard was 802.3av for 10 Gb/s.

What does this new standard mean for the IT industry? The intent of this standard was to support faster connection speeds for server-to-server operations, so don't expect to be purchasing a 40 Gb/s router and NIC from your local electronics retailer anytime soon. In fact, the IEEE 802.3ba task force specifically recognized that the current 10/100/1000 Mb/s was appropriate for most implementations of LANs, but that the current 10,000 Mb/s standard was lacking for larger server and network implementations, including the backbone of the Internet.

This new standard doesn't call for or utilize any new media technologies, but rather simply outlines the necessary procedures and protocols to follow when utilizing these connection speeds over existing optical and copper line technologies. The new standard also works with the existing IEEE 802.3 standards, and thus will not require a major overhaul of equipment or infrastructure to implement.
