Network functions virtualization (NFV) separates network functions from hardware to create virtualized networks that can run on commodity hardware, allowing networks to be more flexible and cost-effective. At the core of NFV are the virtual network functions (VNFs) that handle specific networking functions like firewalls, NAT or load balancing. Individual VNFs are connected or combined as building blocks by service chaining to create a fully virtualized environment. ALTEN Calsoft Labs has been in the forefront in the Network Function Virtualization (NFV) space supporting both network equipment manufacturers and telecom operators in development, testing, orchestration, integration and operations support for new VNF deployments. Our industry standard solutions and inhouse developed frameworks serve as accelerators to help customers go to the market faster and achieve business agility and innovation.
