Without Ethernet our networked world would cease to exist. It’s the ubiquitous standard for local area networks. The internet is probably Ethernet’s greatest triumph. Practically every server that delivers content to the internet is networked via Ethernet. Without Ethernet development the internet will choke. Society is moving to a new level of interconnectedness that’s built solidly upon the Ethernet ecosystem. That’s why Ethernet is developing fast.
Ethernet displaces proprietary field buses. As Ethernet displaces proprietary field buses to facilitate the operation of the digital factory. Ethernet switches are the ubiquitous building block of any intelligent network. Ethernet has also become the de facto networking technology in industrial automation even in mission-critical local networks. Modern Ethernet switches have added significant new functionality to Ethernet while decreasing port prices. Ethernet for Vehicles also becomes reality largely to serve the expected boom of camera-based applications in cars.
Operators’ growth will increasingly depend on their having a cloud computing strategy, an approach for the high-growth IT service market and a clear value proposition for the enterprise market. Data center technologies will be hot topic. 10GBase-T Technology will become technically and economically feasible interface option on data center servers. 10GBase-T Technology allows you to use RJ45 connectors and unshielded twisted pair cabling to provide 10Mbps, 100Mbps, 1Gbps, and 10Gbps data transmission, while being backward-compatible with prior generations.
40/100 Gbit/s Ethernet will be a hot topic. Carriers and datacenters have been clamoring for the technology to expand their core backbone networks. 2012–A Return to Normalcy and Pragmatic, Power Conscious 100G article mentions that in 2010 and 2011, the industry saw the first real roll-outs of 100G transport solutions based on Coherent Detection and FPGA-based Framers. In 2012 we’ll start to see 100G taking a bigger place in the build out of new and existing networks around the world. The initial deployments of 100G are clearly too costly and too power hungry to be widely deployed as the primary transport technology, so optical transport marketplace will move to much lower power and lower cost Direct Detection optical transport solutions. The average WDM link for 10G is dissipating about 3.5W per optical module, the average WDM link per 100G is dissipating about about 100W.
The Ethernet Alliance is thinking fast article tells that terabit Ethernet speeds are round the corner. At a time when the networking world is thinking practical thoughts about 40GbE and 100GbE, it is obvious to Ethernet technologists that, given the rapid data growth we are seeing, these speeds are not enough. The Ethernet Alliance (AT&T, Brocade, Cisco, Dell, NetApp, QLogic and many others) is dedicated to the expansion of the Ethernet ecosystem that makes this networked world work.
Cisco’s Visual Networking Index predicts that in 2015, we’ll see about a zettabyte of information running across the internet. That’s about a billion terabytes. The networking world is entering the ZB era. The storage world is already there, according to IDC’s Digital Universe Study.
Quotations from The Ethernet Alliance is thinking fast article:
“We’re going to need more links at higher speed and we’re expecting 400GbE or Terabit Ethernet to be next.”
“Parallel optics will be stepping stones to tomorrow’s generation of Ethernet speeds.”
A few years ago, 100GbE would have seemed like fantasy. Today it is becoming reality.
Terabit Ethernet will surely go the same route, from technology dream through standardisation and production to everyday reality.
