100GbE - The Future of Ethernet

The development of 100GbE, like 10GbE and 1GbE before it, is being driven by bandwidth exhaustion. At first glance, the development cycle of 100GbE seems to mirror earlier 10GbE and 1GbE efforts, but there are several key areas where 100GbE breaks new ground. For the first time, the bandwidth of the data stream is on the same scale as color channel spacing. Thus, new spectrally efficient modulation techniques can be employed. Also, MAC and PHY data rates have been separated. Any PHY rate can be used, enabling efficient channelization. For the first time, a new Ethernet standard has been optimized for networking and computing applications. On the surface, 100GbE is just the latest speed boost for Ethernet, but if you dig deeper you will find that 100GbE offers much more. Read on to discover the promise of 100GbE.

OpenFlow and SDN – The Missing Pieces in the Cloud Computing Puzzle?

Posted 09 May 2012 by Christian Illmer

Cloud Computing has been around for quite a while and even though some people considered it being just a marketing hype it seems the concept has made its inroads into corporate IT and data centers. It was once defined by the National Institute of Standards and Technology (NIST) as “Convenient, on-demand network access to a shared pool of configurable resources which include networks, servers, storage, applications and services.

Mobile Traffic and the Seismic Shift

Posted 02 May 2012 by Gareth Spence

Whenever I travel, my iPhone becomes my communication workhorse: My go to device for talking to customers, to team members, to friends, to family. However, there's a definite shift taking place in how I use this device. I've just returned from two weeks in Munich and checked my usage. While away, I used only 17 minutes of traditional voice calls. However, on the data side of the house, the figures were a little higher ... Read more
Actually, Timing is Everything

Posted 19 April 2012 by Michael Ritter

The shift from voice to data-centric mobile networks has resulted in a move from traditional TDM services to a wide-scale adoption of Carrier Ethernet in mobile backhaul. Without any legacy TDM-links, however, base stations risk being isolated from traditional synchronization references. Read more
