Synthetic evaluation on the performance of network coordinate systems

Network coordinate systems can improve the performance of large distributed applications on the Internet. However, the current methods for performance evaluation on network coordinate systems are based on static and individual indicators, which cannot fully show their performance. In this paper, we firstly study some evaluation indicators on network distance prediction, and point out their disadvantages. Then, a synthetic evaluation indicator is proposed to evaluate the performance of network coordinate systems. At last we give an example to show how the synthetic evaluation indicator works.
