A system and methods to optimize the resource planning of ADSL services is
provided. In an illustrative implementation, a network management system
(NMS) communicates with an ADSL network to provision resources for
participating users. The provisioning process yields a permanent virtual
circuit (PVC). Included in the provisioning process is the creation and
management of configuration variables, such as, the virtual path
identifier (VPI) and the virtual circuit identifier (VCI). The VPI/VCI
combination uniquely identifies each PVC. If the provisioning process is
aborted or fails, it may be reanimated by the NMS using the VPI/VCI
combination. In this implementation, the VPI may be set to a constant
value and the VCI value calculated using ADSL configuration values (e.g.
the physical connection position on a first, second, third, etc. ADSL
network component.) The deterministic nature of the VPI and VCI
configuration variables assist the NMS to track and optimize available
resources.
