Design of a HAN Autonomic Control Loop

For the most part, research efforts and studies have concentrated on operators' high-capacity core networks and complex access networks. Moving beyond the access network, however, toward the outer edge and into the domain of the end-user, it is clear that a unique and equally complex set of network management problems exists. In this paper, we present the implementation of an autonomic framework that allows operators to manage the increasingly diverse range of resources, services, protocols and standards that exist in outer edge networks. This framework consists of critical software components that allow nodes and devices to be monitored, processed, modeled and managed within Home Area Networks (HAN). A distributed event processing component, a service modeling component, a fault management component and an innovative device adaptation layer have been integrated on a proof-of-concept testbed and are organized to capture knowledge relating to network capabilities and to provide self-managing corrective actions.
