Abstract

Described are systems and methods for implementing and operating a Device Abstraction Proxy (DAP). In one embodiment, the DAP includes a communications interface to connect the DAP to one or more access aggregation devices, each having a plurality of physical ports to provide Digital Subscriber Line (DSL) communication services to a plurality of remote DSL terminals via the plurality of physical ports. The DAP may further include a memory and processor to execute a virtual access aggregation device, in which a subset of the plurality of physical ports are allocated and linked to corresponding logical ports. The DAP may further include a global rule-set module to define operational constraints for the DSL communication services, and a management interface to allow at least one broadband access management system to manage the subset of physical ports allocated to the virtual access aggregation device subject to the operational constraints.
