Abstract: Network traffic measurements provide essential data for networking research and network management. In this article we describe a passive monitoring system designed to capture GPS synchronized packet-level traffic measurements on OC-3, OC-12, and OC-48 links. Our system is deployed in four POPs in the Sprint IP backbone. Measurement data is stored on a 10 Tbyte storage area network and analyzed on a computing cluster. We present a set of results to both demonstrate the strength of the system and identify recent changes in Internet traffic characteristics. The results include traffic workload, analyses of TCP flow round-trip times, out-of-sequence packet rates, and packet delay. We also show that some links no longer carry Web traffic as their dominant component to the benefit of file sharing and media streaming. On most links we monitored, TCP flows exhibit low out-of-sequence packet rates, and backbone delays are dominated by the speed of light.
  • datasets: from about 30 bidirectional links at four POPs out of about 5000 links in the Sprint IP backbone; Three POPs are located on the east coast of the United States, and one POP on the west coast;
  • use port number to identify the application;
  • give a short description of IPMON which consists of three elements: a set of passive monitoring entities that collect packet traces; a data repository that stores the traces; an analysis platform that performs offline analysis;
