IEEE Approves 40 and 100 Gigabit Ethernet

IEEE today announced the ratification of IEEE 802.3ba 40Gb/s and 100Gb/s Ethernet, a new standard governing 40 Gb/s and 100 Gb/s Ethernet operations.

An amendment to the IEEE 802.3 Ethernet standard, IEEE 802.3ba, the first standard ever to simultaneously specify two new Ethernet speeds, paves the way for the next generation of high-rate server connectivity and core switching.

The IEEE 802.3ba standard, ratified June 17, 2010, addresses critical challenges facing technology providers today, such as the growing number of applications with demonstrated bandwidth needs far exceeding existing Ethernet capabilities, by providing a larger, more durable bandwidth pipeline. Furthermore, collaboration between the IEEE P802.3ba 40Gb/s and 100Gb/s Ethernet Task Force and the International Telecommunication Union?s Telecommunication Standardization Sector (ITU-T) Study Group 15 ensures these new Ethernet rates are transportable over optical transport networks.

IEEE 802.3ba is expected to trigger further expansion of the 40 Gigabit and 100 Gigabit Ethernet family of technologies by driving new development efforts, as well as providing new aggregation speeds that will enable 10 Gb/s Ethernet network deployments. The standard?s ratification also dovetails into efforts aimed at delivering greater broadband access, such as the U.S. Federal Communication Commission?s "Connecting America" National Broadband Plan, which calls for 100 Mb/s access for a minimum of 100 million homes across the U.S.

In addition to providing an increased bandwidth pipeline, IEEE 802.3ba remains compatible with existing IEEE 802.3 installations. The new standard is also expected to generate concrete benefits, such as lowered operating expense costs and improved energy efficiencies, by simplifying complex link aggregation schema commonly used in today?s network architectures. Key stakeholders for IEEE 802.3ba include users and producers of systems and components for servers, network storage, networking systems, high-performance computing, data centers, telecommunications carriers, and multiple system operators (MSOs).
