NFV Application Development Training Bootcamp for Service Providers

NFV Application Development Training Bootcamp – NFV Planning, Design and Engineering Workshop

NFV Application development training focuses on techniques and procedures on how telecom and  Mobile Communication Service Provider (CSP) can transform their network functions and deploy NFV.  Learn how to plan and model Network Functions Virtualization Infrastructure (NFVI)  applied to compute, networking, and storage requirements. Learn about different approaches and architecture including ETSI MANO.
