Internet path available bandwidth is an important metric for distributed application performance optimization. However, current network coordinate system causes large errors when being used to predict such performance metric. In this paper, based on theoretical and Internet measurement data analysis result, we show that though not strictly satisfy the constraint, Internet path available bandwidth...
Network coordinate system provides a method to predict distances between network nodes by geometric space embedding, which can help distributed applications such as P2P and Grid select the best node to transfer data. However, how to select the suitable embedding space dimension is still an open problem. In this paper, firstly we give an experimental study on the relationship between distance prediction...
Network distance prediction based on network coordinate (NC) system provides an efficient mechanism to obtain network distance (latency) information with limited times of measurements. In this paper, the mathematic principle of metric space embedding in NC system is analyzed, and the basic rule of designing embedding space model is proposed, which is minimizing both embedding transformation complexity...
Network distance prediction mechanism based on network coordinate system provides an efficient way to obtain latency between node pairs with limited times of measurements. However, most of today's prediction mechanisms use single metric space embedding, which cannot describe the complex hierarchical structure of Internet precisely and produce large prediction errors. In this paper a virtual node based...
