We propose a method for trajectory classification based on a general cluster-based methodology, that can be used both off-line in an unsupervised fashion, both on-line, classifying new trajectories or part of them. We use the Earth Mover’s Distance (EMD) and we adapt it in order to employ it as a tool for trajectory clustering. We propose a novel effective(More)
An agile firewall coprocessor is described that is based on field programmable gate array (FPGA) technology. This implementation of the firewall enables a high degree of traffic selectability yet avoids the usual performance penalty associated with IP level firewalls. This approach is applicable to high-speed broadband networks, and Asynchronous Transfer(More)
This paper investigates the use of ATM for cluster based computing. The need for a native ATM API is discussed as well as the performance of message passing libraries (MPL) that are written to use such an API to exploit the advantages of a high-speed network for cluster-based computing. The MPLs offer a standard interface, such as PVM or MPI, and(More)
This paper outlines some of the problems and the solutionsdeveloped to support geographically distributed computing via ATM. In particular, applications developed with the Parallel Virtual Machine (PVM) [1] message passing library, communicating via ATM at OC3c speeds (155 Mbps) through the NASA ACTS satellite are considered. A primary goal of this work is(More)
