Low-Overhead End-to-end Performance Measurement for Next Generation Networks

<06> IEEE TNSM is the flagship outlet in the computer network and service management area. This article proves using rigorous scientific methods that always-on instrumentation of Internet traffic (for measurement and management) at commodity hardware and software end-systems has a minimal and statistically insignificant footprint on systems' operational performance. The work breaks new ground and contradicts the common belief (and practice) that performance measurement mechanisms should be independent from the network’s main forwarding operation, thus unavoidably trading measurement accuracy for low overhead. Download figures support the view that this research may be a promising basis for instrumentation in future (resilient) networks.
