Did you visit any of this year’s major communication conferences? If so, I’m sure you noted service providers and vendors talking a lot about the increasing relevance of the network edge. There’s a common understanding that powerful edge servers will soon be hosting virtual network functions and control processes in proximity to the customer or an enterprise appliance. But what might look like a logical complement to central clouds needs to be seen as a disruptive change to long-standing network design best practices, with complexity being centralized to create economies of scale and operational savings. So what created this shift in network architectural preferences and how will this unfold next year?

Service providers are working to replace customer premises equipment (CPE) appliances with software running on a standard platform referred to as universal CPE (uCPE). They also want to minimize the steps required for setting up uCPE, both in the supply chain and at the customer site. In an ideal situation, the deployed uCPE would not require user intervention, and there would be no need for a technician on site. This is what we refer to as zero touch ...

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 ...

The software-defined wide area network (SD-WAN) is emerging as one of the hottest growth areas for the enterprise. With the demands of mobile users, the IoT and the emerging digital services market continuously pushing virtualized infrastructure past the data center to the cloud and beyond, organizations are in dire need of rapid provisioning and agile connectivity over the long haul. But this is leading to a conundrum of sorts: Is it better to adopt a fully managed SD-WAN or should control be preserved in-house? Or is there even a middle-ground that alleviates much of the day-to-day burdens without risking availability or data integrity?
