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 ...

Network virtualization is the overarching concept for the move to NFV and telco cloud. This evolution hasn’t been easy. Poor performance, high cost and lack of interoperability have all been impediments. Now we’re seeing breakthroughs that are knocking down yesterday’s barriers. In this blog, I describe some requirements for success in this evolution. I also include some success stories about real-world deployments ...
