Timing issues have been a concern of mobile network architects ever since Ethernet - an inherently asynchronous protocol - became important for mobile backhaul. The reasons are obvious enough: without exquisitely maintained timing relationships, user experience degrades or calls terminate because they are not handed over properly from one cell to the next.

Mobile backhaul is a hot topic in our industry not only for a short time. The massive and ongoing growth of data traffic keeps challenging mobile operators with the migration from traditional TDM-based backhaul solutions to packet-based networks. Latest strategies and more efficient ways to design packet backhaul networks have been in focus at the Light Reading Live! Backhaul & 4G Core Strategies for Mobile Operators show in New York City last week.

Late June every summer, the optical networking community convenes on the French Riviera to ruminate about hot topics in the field of optical networking at the “WDM and Next-Generation Optical Networking” conference. This year was no different, with Andrew Schmitt, Directing Analyst with Infonetics Research opening and chairing the sessions of the first day. In his introductory talk Andrew showed a slide summarizing the state of 100G solutions as follows: In 2011 network operators had the choice between two vendors for commercial deployment of 100G systems. In 2012 the list has grown substantially by a factor of five – a point rendered un-debatable by the long list of sponsoring vendors showcasing their 100G solutions(s) in the adjacent exhibition area.

I write this, my first blog, while sitting in a presentation on the ‘Smart Grid’ project which is underway in the US. This project aims to equip the domestic and commercial power grid in the US with tools to support two way power distribution (from and to utility companies), aid power monitoring via distributed meter reading and promote energy conservation. The plan is to deploy IPv6 to millions of Smart Grid devices over the next 3-4 years. Ethernet is acknowledged as a key component of the Smart Grid concept.
