\"400<\/a>The Institute of Electrical and Electronics Engineers (IEEE)<\/a>, launched an IEEE 802.3<\/a> \u201cStandard for Ethernet\u201d study group<\/a> to explore the development of a 400 Gbps Ethernet standard. The new standard will look to efficiently support an ever-increasing, exponential network bandwidth growth. Ethernet which is celebrating its 40th anniversary this year is defined by the IEEE 802.3 standard<\/a>. Ethernet is a pervasive standard, driven by the ever-growing needs of the local area, access, and metropolitan area networks<\/a> around the world.<\/p>\n

Expanded reliance on Ethernet<\/h3>\n

\"IEEE<\/a>Beyond traditional networks, Help Net Security<\/em><\/a> reports that new application like industrial<\/a> and automotive networking are expanding their reliance on Ethernet. To better address the needs of these areas, the IEEE 802.3 Ethernet standard is constantly evolving and expanding. John D\u2019Ambrosia<\/a> is the chief Ethernet evangelist, CTO office, Dell, and chair of the new IEEE 802.3 400 Gbps Ethernet Study Group. He says Ethernet must evolve. \u201cTraffic is growing everywhere … and it\u2019s critical that we move now to create a plan for the Ethernet ecosystem to evolve beyond today\u2019s capabilities, in order to accommodate the burgeoning bandwidth tsunami.<\/em>\u201d<\/p>\n

In August 2012, IEEE forecasted<\/a> that networks will need to support 58% compound annual growth rates (CAGRs) on average. The growth will be griven by simultaneous increases in users, access methodologies, access rates, and services (such as video on demand and social media). IEEE report that networks would need to support capacity requirements of 1 terabit per second (Tbps) in 2015. That number grows to 10 Tbps by 2020 if current trends continue. Alan Weckel, vice president of enterprise and data center market research at Dell’Oro Group said in the article, \u201cEthernet is an arena of constant innovation, driven by the market demand for support of new ever-increasing bandwidth speeds, as well as new protocols, applications, and media types.<\/em>\u201d<\/p>\n

Standards-based networking<\/h3>\n

\"Ethernet\"<\/a>Standards-based networking has worked so far and will be needed as 400 Gbps Ethernet evolves. Mr. Weckel adds, \u201cGlobal bandwidth requirements are continuing to grow exponentially … Standards-based solutions are integral to maintaining business growth across the Ethernet ecosystem.<\/em>\u201d<\/p>\n

David Law, chair of the IEEE 802.3 Ethernet Working Group and distinguished engineer with HP Networking<\/a> explains in the article, \u201cAn IEEE 802.3 study group is formed when there is interest in developing a request to initiate an IEEE 802.3 Ethernet standards-development project.<\/em>\u201d<\/p>\n

\"IEEE<\/a>Dell’s D\u2019Ambrosia told<\/a> Wireless Design Magazine<\/em><\/a> that a host of new technologies and applications have proliferated in the marketplace since the most recent speed jump to 100 Gb\/s Ethernet was ratified in 2010<\/a>. He reminded NetworkWorld<\/em><\/a> that “The iPhone didn’t exist when we started 100G.<\/em>” Mr. D\u2019Ambrosia concludes that the impact has been felt throughout the Ethernet ecosystem. Data centers, for example, where Ethernet is the primary interconnect technology, are at the center of the bandwidth storm. Pressure is intensifying from all directions:<\/p>\n
