The main thought is importing super node according the ability of nodes. And the super node substitutes for ordinary node to access Tapestry system. The overhead of ordinary node and reliability problem caused by updating routing table frequently are shielded. In addition, nodes are zoned based on geographical position to avoid the issue that the adjacent nodes in identity actually far away which caused by hash operation. Better performance in mobility supportive, reliability, error tolerance and memory need are founded based on analysis in theory and experiment. And it's suitable to be used in MP2P Network.In trusty transmission aspect, it will cause a serial problems if introduces TCP protocol directly to MP2P Network. Using a trusty transmission mechanism—Cross-Layer-Optimization Trusty Transmission in MP2P Network is put forward. The main concept is building a communication of cross-layer information to achieve optimization with consideration of interaction of each layer. Performance of the mechanism has been analyzed in theory and proved it's suitable for MP2P Network.
