An XML Routing Synopsis for Unstructured P2P Networks
Qiang Wang, Abhay Jha, M. TAMER ÖZSU · 2006
Many emerging applications that use XML are distributed, usually over large peer-to-peer (P2P) networks on the Internet. The deployment of an XML query shipping system over P2P networks requires a specialized synopsis to capture XML data in routing tables. In this paper, we propose a novel graph-structured routing synopsis, called kd-synopsis, for deployment over unstructured super-peer based P2P networks. This synopsis is based on length-constrained FBsimulation relationship, which allows the balancing of the precision and size of the synopsis according to different space constraints on peers with heterogeneous capacity. We report comprehensive experiments to demonstrate the effectiveness of the kd-synopsis.
