Monitoring the traffic of wide area networks consisting of several autonomous systems connected through a high-speed backbone is a challenge due to the huge amount of traffic. Keeping logs for obtaining measurements is unfeasible. This work describes a distributed real-time strategy for backbone traffic monitoring that does not employ logs and allows arbitrary metrics to be collected about the traffic of the backbone as a whole. Traffic is sampled by monitors that are distributed across the backbone and are accessed by a Stream Processing Engine (SPE). Besides the distributed monitoring architecture, we present an implementation (BackStreamDB) that was deployed on a national backbone. Case studies are described that show the system flexibility. Experiments are reported in which we evaluated the amount of traffic that can be handled.
