Ethernet Alliance White PapersIf you wish to contribute a white paper, please contact Angela Muscat, VP of Education by filling out the Ethernet Alliance contact form. The IEEE P802.3ba 40 Gb/s and 100 Gb/s Ethernet Task Force has been working on the development of 40 Gigabit Ethernet and 100 Gigabit Ethernet. In October 2008, the Task Force took a major step forward, as it generated Draft 1.0 of the amendment to the IEEE Std 802.3™- 2008 Ethernet standard. The Task Force has developed a single architecture capable of supporting both 40 Gigabit Ethernet and 100 Gigabit Ethernet, while producing physical layer specifications for communication across backplanes, copper cabling, multi-mode gigabit per second, and single-mode gigabit per second. This white paper provides an overview of the 40 Gigabit Ethernet and 100 Gigabit Ethernet project and the underlying technologies.
The Ethernet Alliance converged data center demonstration shows the deployment of several types of mixed traffic over a multi-vendor 10 GbE infrastructure with physical links that consist of both UTP copper, twinax copper and fiber optic media. The SAN/LAN network is converged at Layer 2 using Ethernet as the common transport protocol. The demonstration data center runs 10 GbE application–to-application traffic, iSCSI storage and low latency traffic with a streaming video environment from iSCSI storage, FCoE over a lossless Ethernet network and converged traffic types via virtualized servers. The Ethernet Alliance demonstration shows a physical data center built with equipment from multiple vendors, switches, network interface card (NICs), converged network adapters (CNAs) and cabling systems that supports a complex yet realistic set of 10 GbE application environments.
Data Center BridgingNetworks are the essential part of any modern data center and they must deliver reliability, availability and high performance. Enterprises rely on their data centers to run business operations, service providers rely on their data centers to generate revenues by delivering network services, and content providers rely on their data centers to distribute revenue-producing content. Ethernet is the most widely deployed networking technology today. Currently, it fulfills increasingly demanding requirements for a variety of business needs. But can Ethernet technology evolve to help data centers improve costeffectiveness and meet the demands for next-generation services?
The wide adoption of 1G Ethernet passive optical networks (EPON) (per IEEE std P802.3ahTM) provided a significant jump in access network capacity and created demand for greater bandwidth-intensive applications and services such as Internet Protocol Television (IPTV), Video-on-Demand (VoD) and high-grade internet protocol (IP) telephony known as Voice over IP (VoIP). To address these market demands, the IEEE P802.3av Task Force was created in September 2006 and its 10G-EPON draft builds upon the compatibility with the existing 1GEPON.
