The data center interconnect (DCI) is emerging as a key element in the enterprise strategy to transition to a more digital-oriented business model, one that encompasses multiple data processing and storage sites on the cloud and the IoT edge. At the same time, however, static network connectivity both within the data center and over the wide area is becoming increasingly virtualized and software-defined, meaning that in the very near future organizations will take to managing and optimizing their DCI infrastructure as code ...

Vodafone has successfully completed a live network trial in Spain with the Facebook-designed Voyager optical “whitebox” as part of its work with the Telecom Infra Project (TIP). An increased demand for data is driving the need for more scalable and cost-effective infrastructure. To solve that challenge, telecoms operators need a combination of connectivity and scalable and cost-effective fiber-based infrastructure ...

Communication service providers will remember the days when service innovation cycles took many months or even years. The process was long and troublesome, starting with the operator’s idea for a new service, followed by detailed technical discussions with the network supplier, feasibility studies and estimations of related development efforts. Contracts for feature extensions were signed. As new hardware became available, system integration and testing had to be performed. Finally, a new service could be launched. By this stage, many months or even years had passed and the conditions that made the service attractive in the first place may no longer exist ...

Network control and management is a complex task, incorporating cloud operations, core and metro transport, mobile fronthaul and backhaul connectivity all the way to user applications. Setting aside optimizations and assurance mechanisms, running applications on such a diverse and distributed infrastructure is a challenging task in itself. With localized and highly engineered network operational tools, it typically takes several days or even weeks for any changes, upgrades or service deployments to take effect ...

For this post, I got together with Maria Cuevas, head of mobile core networks research at BT, to look ahead to our joint MWC demo. "MWC 2018 Threatens to Be 5G New Radio Bore," wrote Light Reading's news editor, Morris Lore, fearing that the non-radio side of the 5G overhaul wouldn't get much of a look in at the year's biggest mobile event. Well, it doesn't feel like that from where we are. For our team heading out to Barcelona, things are looking exciting - frantic even - as we prepare our demonstration of network slicing and assurance for 5G ...
