Enterprise networks contain hundreds, if not thousands, of cooperative end-systems. We advocate devoting a small fraction of their idle cycles, free disk space and network bandwidth to create Anemone, a platform for network management. In contrast to current approaches which rely on traffic statistics provided by network devices, Anemone combines end-system instrumentation with routing protocol collection to provide a semantically rich view of the network.
