Software-defined networking (SDN) is an emerging network technology that decouples the control plane from the data plane. Using SDN, a fine-grained flow-level inspection for cyber security can be performed by capturing suspicious packets on the network and steering the captured traffic to a traffic analyzer. This work proposes a flow inspection scheduling for various types of traffic flows on S...

By computing the probability distributions of the velocity difference between cars a time-delay r apart, the scaling properties of traffic flow can be analysed. These data display scaling behaviour thus confirming earlier results that have found 1/ /-noise in traffic flow. Furthermore, the applicability of the scaling analysis for describing the two-point statistics of traffic flow is demonstra...

Though the popular Cisco NetFlow is widely used for flow-level traffic measurement in IPv4 networks, it is not suitable for IPv6 networks because of the fixed flow structure that cannot carry IPv6-related information. Therefore, the IETF IP Flow Information eXport (IPFIX) standard that employs the flexible flow template structure has been recently proposed to support various flow-level traffic ...
