ANCORS: Adaptable Network COntrol and Reporting System

ANCORS is a distributed tool suite that merges technology from network management , active networking, and distributed simulation in a uniied paradigm to assist in the assessment, control, and design of computer networks. This paper explores some of the advantages that can be obtained from merging the three technologies, and describes how ANCORS integrates complementary elements of each. ANCORS's architecture ooers substantial software reuse, scalability, and exibility and supports an extensible mechanism to employ multiple network management protocols of varying degrees of complexity. This paper also describes network engineering and monitoring services that were implemented to prototype some of ANCORS's architectural ideas and provide practical experience for their reenement.
