Abstract

We present the architecture, design, and implementationof a Smart Environment for Network Control, Monitoringand Management (SENCOMM). SENCOMM uses activenetwork technology to comprise a Management ExecutionEnvironment (SMEE), which coexists with other executionenvironments (EEs).Management applications, calledsmart probes, run in the SMEE.A probe and its data aremobile executable code that are delivered to the active nodewithin an Active Network Encapsulation Protocol (ANEP)datagram.Our architecture is designed to actively control, monitor,and manage both conventional and active networks, and beincrementally deployed in existing networks.We present a set of goals, a design philosophy, and a set of basic requirements for controlling, monitoring, and managing networksusing active network technology.We discuss the operationand components of SENCOMM: the management EE, a protocol, smart probes, and loadable libraries.We discuss theimplementation issues uncovered in integrating SENCOMMinto a selected EE and the decisions made to resolve them.
