IEEE ratifies high-rate Ethernet spec Bernard Cole San Francisco, Ca. – The IEEE has ratified a new standard for 40 Gb/sec and 100 Gb/s Ethernet connectivity An amendment to the IEEE 802.3 Ethernet standard, IEEE 802.3ba is the first standard ever to simultaneously specify two new Ethernet speeds, opening up the way for a new generation of high data rate Internet and local Ethernet-enabled server connectivity and core switching. The IEEE 802.3ba standard addresses such issues as how to satisfy the demands of a growing number of applications with demonstrated bandwidth needs far exceeding existing Ethernet capabilities. This has been done by providing a larger, more durable bandwidth pipeline, the result of collaboration between the IEEE P802.3ba 40Gb/s and 100Gb/s Ethernet Task Force and the International Telecommunication Union’s Telecommunication Standardization Sector Study Group 15. Intended to ensure that these new Ethernet rates are transportable over optical transport networks, IEEE 802.3ba eliminates bottlenecks caused by the growth of bandwidth-intensive applications more powerful server architectures by providing a scalable architecture for meeting current bandwidth requirements and laying a solid foundation for future Ethernet speed increases. IEEE 802.3ba remains compatible with existing IEEE 802.3 installations, IEEE said. 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, according to IEEE.
