A virtualized cellular access node includes a control plane interface coupled to a physical cellular access node, a first virtualized network function that receives a first portion of data, a second virtualized network function that receives a second portion of data, and a third virtualized network function that receives a third portion of data. The control plane interface receives data related to a cellular network having cellular terminals. The first virtualized network function analyzes the first portion of data and generates a first instruction related to traffic allocation within the cellular network. The second virtualized network function analyzes the second portion of the data and generates a second instruction related to bandwidth allocation within the cellular network. The third virtualized network function analyzes a third portion of the data and generates a third instruction related to quality of service assignment to a first cellular terminal within the cellular network.

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.
