A digital distributed antenna system (DDAS) that regains the capability to perform simulcast to multiple simulcast groups while using a base station's direct digital output is provided. The User Plane data is adapted for simulcast and also for eliminating time delay ambiguities across multiple simulcast digital radios. In addition, the Control and Management Plane is aggregated across multiple remote units to allow a non-modified donor digital base station to control simulcast groups. The result is a low cost digital DAS that can efficiently distribute the capacity of a digital base station to solve coverage and capacity requirements in a manner similar to that now accomplished using a traditional base station with RF in/out.

Autonomous link discovery specifies a method and associated procedures that automatically discover various levels of transmission links and paths between transport network elements residing in the transport plane of communications networks. Unlike more traditional centralized polling techniques rooted in a management plane, autonomous link discovery procedures are rooted in and triggered by network elements composing the transport plane. As such, autonomous link discovery procedures may be event driven and execute in a coordinated, distributed fashion to automatically detect new link connectivity associations and correlate link endpoint attributes between these network elements. Once successful link correlations have been determined, autonomous notifications of these correlated link associations are sent to management elements and/or control elements residing in their respective management and control plane domains.

A method and system for changing the extent of data plane resources controlled by a control plane for a network connection which spans a contiguous set of nodes controlled by existing network control resources is disclosed. This is done in a non-disruptive manner. This typically involves two steps: i) Creating a new set of control plane resources for said network connection such that said data plane resources are shared with said existing network control resources; and ii) then terminating the existing network control resources such that said data plane resources are fully transferred to the new set of control plane resources without disrupting said network connection. The existing network control resources can be either a control plane resource or a non control plane resource. An example of a non control plane resource is network management software (e.g., an OSS (Operation Support System)), which forms part of the Management Plane. It should be noted that this does not need to be done for a complete end-to-end connection, but rather can be executed for the portion of the end-to-end connection which is to be controlled by the control plane.
