dc.description.abstract 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 to mitigate such effect: a simple algorithm to distribute inter-batch time among the packets composing a batch, and a driver modification to poll NIC buffers avoiding batch processing. Experimental results, using both synthetic and real traffic, show that our proposals allow capturing accurately timestamped traffic for monitoring purposes at multi-10Gb/s rates. en_US
