ABSTRACT:
An OA&M system is provided for a network communication core having a switch, a controller, and a core configuration memory. All configuration information which is static (i.e., information which remains the same regardless of the configuration of the core) is placed off-core in a map file. Because of this, requests for information on the configuration of the core may often be satisfied without the need to query the core, thereby reducing core load. Further, this static information in the map file allows validation of requests for dynamic configuration information as well as requests for reconfiguration of the core. In other words, the static information assists in ensuring that requests are proper. The static information in the map file is presented as "list", "attribute", and "choice" features. This presentation facilitates the making of OA&M requests by a user. The features become arguments of functions in order to generate OA&M requests to the controller. Each function received by the controller is converted to instructions for the core by an interface and a map file in the core. The features in the off-core map file are organised into a hierarchical tree (a feature tree) and the off-core map file may be accessed by a browser program of a personal computer so that levels of the tree may be displayed, thereby facilitating quick configuration requests.
