The Internet has opened new avenues for information ac-cessing and sharing in a variety of media formats. Such popularity has resulted in an increase of the amount of resources consumed in backbone links, whose capacities have witnessed numerous upgrades to cope with the ever-increasing demand for bandwidth. Consequently, network traffic processing at(More)
—Novel packet I/O engines allow capturing traffic at multi-10Gb/s using only-software and commodity-hardware systems. This is achieved thanks to the application of techniques such as batch processing. Nevertheless, this feature involves degradation in the timestamp accuracy, which may be relevant for monitoring purposes. We propose two different approaches(More)
SUMMARY As an attempt to make network managers' life easier, we present M 3 Omon, a system architecture that helps to develop monitoring applications and perform network diagnosis. M 3 Omon behaves as an intermediate layer between the traffic and monitoring applications that provides advanced features, high performance and low cost. Such advanced features(More)
In this paper we present an FPGA implementation of a Monte-Carlo method for pricing Asian Options using Impulse C and floating-point arithmetic. In an Altera Stratix-V FPGA, a 149x speedup factor was obtained against an OpenMP-based solution in a 4-core Intel Core i7 processor. This speedup is comparable to that reported in the literature using a classic(More)
—The use of closed solutions from most known vendors to carry out network-monitoring tasks has turned out to be a questionable option given their lack of flexibility and extensibility, which has typically been translated into higher costs. Consequently, we study whether high-performance monitoring tasks can be carried out using off-the-shelf systems, the(More)
