As I look back on my experience at Mobile World Congress (MWC) held last month in Barcelona, I’m struck by how rapidly the Telco and Service Provider industry is changing. As I mentioned in my previous post Telcos and service providers are all engaged in large, complex, multi-year infrastructure and service delivery transformations. The technology transformation is the replacement of dedicated network appliances such as routers and cellular network switches with software running on commercial off-the-shelf hardware. The industry term for this is Network Functions Virtualization (NFV). The aim of NFV is to reduce the time to service, and cost for Communication Service Providers (CSPs) to deliver network services.
