Software-Defined Network Exchanges (SDXs) and Infrastructure (SDI): Emerging innovations in SDN and SDI interdomain multi-layer services and capabilities

摘要

Software-Defined-Networking (SDN) is quickly transforming the networking landscape. Programmable networking based on many types of virtualization techniques, including SDN, enable high levels of abstraction for network services, control and management functions, and underlying technology resources. These approaches enable network designers to create a much wider range of services and capability, including through Software Defined Networking Exchanges (SDXs) than can be provided with traditional networks and exchange facilities, enabling a) many more dynamic provisioning options, including in real time b) faster implementation of new and enhanced services c) enabling applications, edge processes and even individuals to directly control core resources; e) substantially improved options for creating customizable networks and e) enhanced operational efficiency and effectiveness. In addition, these capabilities are now being extended to other types of Software Defined Infrastructure (SDI), including clouds, compute grids, storage devices, instruments, and many other types of edge devices.
