Three tips for making NFV a reality in 2016

The outgoing 2015 was a year of transition for network-function virtualization (NFV) deployment. It was a year in which carriers were looking for a proof of concept and initial commercial deployment. In 2016, this trend is expected to intensify further, and NFV will be deployed live and in projects such as vCPE and vEPC. Communication service providers (CSPs) must therefore address the challenges neglected so far. Some of these challenges include security, performance, return on investment (ROI), carrier-grade and interoperability with existing networks, Operational Support Systems (OSS) and Business Support…

How Virtualizing security can protect SDN and NFV networks from cyber attacks

Telecommunications operators and similar communications service providers are excited about the opportunities that Software Defined Networks (SDN) and Network Functions Virtualization (NFV) promise to provide. SDN and NFV technologies and their ability to improve network versatility, reduce operational costs and create new business opportunities are attracting significant interest from service providers of all sizes and in all regions around the world. Although the operational use of SDN and NFV is still in early stages, most service providers are currently formulating their strategies for deploying these technologies and many are conducting…

Carrier roadmap to NFV

As a service provider, it’s hard to envision how Network Function Virtualization (NFV) will affect your network, the services you provide, your customers, your employees and investors. Many in the industry believe that NFV will become an integral part of service providers’ infrastructure and the foundation for most of the services.  According to HIS, the global NFV hardware, software and services market is predicted to reach $11.6 billion in 2019, up from $2.3 billion in 2015. However, the NFV landscape is still evolving and the key to success would be…

NFV shakes up service providers’ revenue

For many service providers, NFV – Network Function Virtualization – is a long term project. They consider the capital investment to be substantial and the technical complexity to be risky. Take for example network architecture. Migrating existing services to NFV requires changes in the providers’ network topology. Virtualizing IMS not only requires changing the network but also poses uncertainty when replacing dedicated hardware with standard hardware and software. The initial investment would be high and ROI will only be achieved in a number of years. If only there were NFV…
