Impacts and Recommendations

  • The holistic control of SDN with the elasticity of NFV gives CSPs new and more flexible business models, but they will also need new support systems
  • SDN optimizes vendor selection for CSPs, allowing them to manage their multivendor IP networks more efficiently
  • SDN's revolutionary promise has created a lot of supplier hype, making it critical for CSPs to develop vendor-evaluation criteria
  • Newer requirements for dynamic security inspection will force CSPs to tune SDN-controlled networks with NFV functions such as deep packet inspection, as needed
