Measurement and estimation of packet loss characteristics are challenging due to the relatively rare occurrence and typically short duration of packet loss episodes. While active probe tools are commonly used to measure packet loss on end-to-end paths, there has been little analysis of the accuracy of these tools or their impact on the network. The objective of our study is to understand how to measure...
Service level agreements (SLAs) specify performance guarantees made by service providers, typically in terms of packet loss, delay, delay variation, and network availability. While many tools have been developed to measure individual aspects of network performance, there has been little work to directly address the issue of SLA compliance monitoring in an operational setting where accuracy, parsimony,...
We describe a traffic generation framework for online evaluation and tuning network intrusion detection systems over a wide range of realistic conditions. The framework integrates both benign and malicious traffic, enabling generation of IP packet streams with diverse characteristics from the perspective of (i) packet content (both header and payload), (ii) packet mix (order of packets in streams)...
