Editorial for Computer Networks special issue on 'Measurement-based optimization of P2P networking and applications'

摘要

Measurement plays an important role in various Peer-to-Peer (P2P) applications: for peer selection, data delivery and overlay construction. Since P2P systems may include hundreds of thousands of online peers at the same time, it is necessary for the measurements to be scalable. With a dedicated or co-located measurement element such as a network coordinate system or traffic monitor, a P2P system can utilize the measurement results to either improve the system's performance or ensure the system's robustness.
