The document discusses SDN and NFV for carriers. It outlines challenges like network inflexibility and high costs, and opportunities like virtualization and software-defined networking. It provides an overview of NFV and SDN, including definitions and benefits. Use cases are presented that demonstrate how SDN and NFV can address challenges and enable new services. A phased approach is suggested for service providers to adopt NFV and SDN technologies.

Use Case Summary Nb Name Description #1 Appliance Migration Migrate proprietary boxes to COTS servers, decouple Data & control plan, leverage SDN protocols, controllers, centralized controller for multiple data plane components etc #2 Traffic Steering Introduce SDN with controller to extract 1st packets, tag flow and avoid having to redo this for all packets. Allow dynamic change #3 Content Delivery Traffic routing Allow dynamic traffic routing thanks to SDN controller and dynamic view of available NW resources #4 Virtual Core IMS Enhance Policy with tight integration with SDN controller to route traffic to virtual core IMS #5 Networking as a Service Extand IaaS with dynamic NW resource allocation and allow Telecom operators to offer this as a Service to external customers #6 Edge policy Enforcement Have a centralized control but distributed enforcement model for Security policies. #7 Cloud Bursting Burst from Private Cloud to Public Cloud and be able to orchestrate the dynamic secure network in the public cloud #8 Optimal Traffic Engineering Inter-DC WAN Ability to have a Stateful controller to more dynamically place flows in the network, to best utilize the network resources #9 Data Center Virtualization Ability to move workloads around from any server to any other server within a DC 8 without limitations of the network addressing © Copyright 2012 Hewlett-Packard Development Company, L.P.
