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 provides an experimental assessmentof the impact of the underlying networking in a cluster-based computing environment. The assessment is quantified through application level benchmarking, process level communication, and network file I/O. Two testbeds are considered one small cluster of SUN workstations and another larger cluster composed of(More)
– This paper outlines some of the problems and the solutions developed 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(More)
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)
