A programmable architecture for scalable and real-time network traffic measurements
Accurate and real-time traffic measurement is becoming increasingly critical for large variety of applications including accounting, bandwidth provisioning and security analysis. Existing network measurement techniques, however, have major difficulty dealing with large number of flows in today's high-speed networks and offer limited scalability with increasing link speeds. Consequently, the current state of the art solutions have to resort to conservative sampling of the traffic stream and/or accounting for only a few frequent flows that often fail to provide accurate estimates of traffic features. In this paper, we present a novel hardware-software codesigned solution that is programmable and adaptable to runtime situations offering high-throughputs that can easily match current link-speeds. The key to our design is orthogonalization of memory lookups from traffic measurements through our query-driven measurement scheme. We have prototyped our approach on a Xilinx platform using...
