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 ...

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 ...

Layering is a well-known strategy for security. By using layers, we increase the difficulty of penetration and reduce the impact of a failure at any given layer. Here are some guidelines for applying layered security to universal customer premises equipment (uCPE) deployments. The uCPE layers include the platform layer (including management, virtualization, and networking), the application layer, and the management and orchestration (MANO) layer. As a reminder, uCPE consists of software virtual network functions (VNFs) running on a standard operating system hosted on a standard server. An ideal uCPE deployment supports a multi-vendor multi-component construction, underscoring the need for security at multiple layers ...

Multi-access edge computing (MEC) is expected to play a strategic role as networks transform, bringing new levels of performance and access to mobile, wireless, and wired networks in support of future services and applications. A key goal of MEC is to reduce network congestion and improve application performance by moving functions, content and processing closer to the subscriber. By doing so, network operators will be able to better utilize network resources while also improving the delivery of content and applications to provide end users with a better quality of experience through lower latency and higher bandwidth ...

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 ...
