Network Virtualization: The Next Evolution of Service Provider Networks Intel® microarchitecture improvements have significantly reduced the need for specialist silicon, enabling network service providers to leverage the proven scalability of modern virtualized data center technology. Historically, network service provider business models were based on the ability to securely partition bandwidth on a shared platform between multiple circuits for individual customer services. Nextgeneration network architectures have enabled consolidation at the frame and packet level using IP, MPLS, and Ethernet technologies. However these approaches have had limited impact at the service level, which is the key to future revenue yield. To add services to current networks, network service providers generally add fixed-function packet processing appliances, creating a network that is difficult to power-manage, costly to scale, and cumbersome to expand. To regain profitability, network service providers must either reduce network costs or find new means of generating revenue— or both. By deploying network functions as software applications, network service 2 providers can gain flexibility lacking in current network environments and can achieve cost reduction and service velocity already proven in enterprise data centers. Intel® Architecture: A Flexible, Scalable Approach to Network Expansion Intel® architecture provides network service providers with a standard, reusable, shared platform for SDN that is easy to upgrade and maintain. Recent Intel® microarchitecture improvements have significantly reduced the need for specialist silicon, enabling network service providers to leverage the proven scalability of modern virtualized data center technology. Advantages of this approach include a streamlined network and cost savings through hardware reusability and power reductions. The adoption of Intel® processor-based network components also enables network service providers to integrate solutions currently being developed by independent software vendors (ISVs).
