This year, the IP Flow Information Export (IPFIX) protocol will become standard for exporting flow information from routers and probes. Standardized methods for packet selection and the export of per packet information will follow soon from the IETF group on packet sampling (PSAMP). The future availability of network information in a standardized form(More)
* Centre for Advanced Internet Architectures, Swinburne University, Melbourne Australia + Autonomic Networking Technologies, Fraunhofer FOKUS, Berlin, Germany AbstractIn this paper we describe a passive technique for round trip time (RTT) estimation called Synthetic Packet-Pairs (SPP). Regular and frequent measurement of round trip time (RTT) between points(More)
IP flow data provides input for accounting, traffic engineering and security applications. The storage of flow data is required to allow off-line processing, archiving, and sharing of traffic traces. Currently this is achieved with a variety of proprietary solutions, which results in a variety of formats as input for flow processing tools and hinders data(More)
Network security often requires the surveillance of the actual traffic in the network. Methods like signature-based attack detection or the detection of traffic anomalies require input from network measurements. The IETF currently standardizes the IP Flow Information Export (IPFIX) protocol for exporting flow information from routers and probes. The packet(More)
