Abstract :
Control-plane functions are migrating from dedicated network equipment into software running on commodity hardware. The Software- Defined Access Network (SDAN) concept introduced here extends the benefits of Software- Defined Networking and Network Function Virtualization (NFV) into broadband access. In a SDAN, access-network control and management functions for broadband access are virtualized, to streamline operations, speed services creation, and enhance broadband customer satisfaction, particularly in multi-operator environments. This article examines industry drivers, identifies software- definable control and management functions for broadband access, and presents some specific usage scenarios for the SDAN.
