Abstract:One can perform ad-hoc network management by means of a hierarchical distributed NMS (Network Management System). On top of this, an (external) OSS (Operation Support System) should be able to extract network information and introduce new management policies. This functionality can be regarded as mission critical to network management. Therefore a dependable interface between the OSS and the hierarchical distributed NMS should exist. Typically a hierarchy has only one top-node with a full overview. It is therefore the function of this top-node to interface with the OSS. However nodes on ad-hoc networks are not particularly dependable in terms of availability, service responsiveness and service capacity. This thesis presents a design that addresses the dependability issues for this top-node service. The Celtic Madeira hierarchical distributed ad-hoc NMS is used to illustrate and evaluate the design. It provides the OSS interface by means of Web services, while the framework itself is mainly based on Java. The presented design allows the interface service to operate as a single logical entity, while it is actually distributed among multiple nodes.
