Actually, Timing is Everything
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. As mobile operators increasingly deploy 4G radio access technologies and depend on accurate delivery of synchronization, they are now seeking advanced solutions that not only accurately deliver the required timing information over packet networks but also provide assurance regarding its availability.

Cloud Computing 2.0
With the conference season already being in its full swing, people attending major industry events are eager to hear and see what’s coming next in terms of technology and applications. One of many, but popular topics is cloud computing. Some might say: sounds familiar, what’s new? Clearly, the momentum continues. Service providers and vendors are addressing the cloud from many more different perspectives now compared to the past. So has happened at the MPLS & Ethernet World Congress in Paris and at the Lambdanet Forum in Frankfurt last week. Cloud computing was one of the main themes at both events, with speakers presenting new solutions and discussing their experience in the field. Read more
Software Defined Networking Comes of Age
New trends and rapid technological advances in IT and telecommunications are changing the way telecom networks are designed, deployed and managed. The list of innovations driving the continuously increasing demand for bandwidth is long. Mobile end-user devices are becoming smarter, rich media content such as video is commonly adopted for business and private consumption, applications are increasingly implemented in a network-based fashion and are pushed into the cloud, social media became part of our daily lives – and many more. Consequently, the architecture of the Internet has changed as well over the last years. Widely spread usage of e-mail, e-commerce, search engines, social networks and cloud computing are only a few examples driving this change.
Many of the new and trendy innovations have been enabled through migrating telecom networks from a static, circuit-switched infrastructure to a more flexible and scalable packet-based technology. The wide-scale adoption of Ethernet as a transport protocol and the increased usage of fiber in all parts of the network allowed operators to provide more bandwidth at significantly lower cost.

How Much Ethernet OAM is Appropriate?
Another year, another Light Reading Ethernet Expo Americas. This show is the premier event covering the hot topic of Carrier Ethernet network technologies and services in the Americas. It was a must-attend Carrier Ethernet networking event also this year, where dozens of experts from the service provider, supplier and analyst community met in New York City.
The two-day event saw a series of informative presentations and panel discussions. Not so much on technology evolution and innovation anymore. Much more focused on how Carrier Ethernet is used and will be used in future networks. And a lot of discussions exploring how Carrier Ethernet will enable new applications including cloud services and how these applications will influence Carrier Ethernet equipment.

The Idea of a Consolidated Network
There was a lot of traffic at this year’s Ethernet Europe in London. The two-day conference and exhibition saw a high number of industry experts and a Carrier Ethernet debate that shifted away from hardware and technology to deployment scalability and service development.
While a few years ago, there was a lot of debate about the different choices of backhaul technologies including fiber, copper and microwave, there is now much greater agreement on making use of all technology alternatives available to build networks aligned with business needs. The ubiquitous delivery of services and their efficient management to enable new applications became far more important – whether for business, mobile backhaul or wholesale.
