P2P: From Unstructured, Structured to Semantic Network Lican Huang Zhejiang Sci-Tech University, China
Although client/server technology has been successful in many IT fields, it has many shortcomings. P2P technology is now considered as the next generation computing model. There are mainly two types of P2P technologies. The unstructured approach routes nodes by a flooding algorithm. The structured approach is mostly based on Distributed Hash Table (DHT) technologies. However, these two kinds of P2P approaches do not care about the semantic meaning of the nodes. They do not care about the nodes whose users may take different roles in social groups in the communities.
This talk will introduce a semantic P2P Network -- Virtual Hierarchical Tree Gird Organizations (VIRGO). The nodes are identified as domain names classified by the semantic meaning of their contents and roles. VIRGO is a hybrid of unstructured P2P and structured P2P technologies by merging a multi-tuple Virtual Hierarchical Overlay Network and random cached network. It has aspects of decentralization, scalability and availability.
This talk will give the audience the concepts, framework, protocols and applications about VIRGO, and will point out the benefits of VIRGO such as complicated resource discovery by SQL-like statements.
Prof. Huang works on challenges about Grid and P2P computing. He has worked on e-Science and Grid computing since the beginning of 2000’s. He was mentioned in Marquis Who’s Who in the World 2006, Marquis Who’s Who in the Science and Engineering 2006-2007, and Marquis Who’s Who in Asia 2006-2007 due to his achievement of proposing Virtual and Dynamic Hierarchical Architecture for e-Science, Grid and VIRGO protocols.
Prof. Huang now is a Director of Network & Distributed Computing at Zhejiang Sci-Tech University (ZSTU), China. Prior to joining ZSTU, Prof. Huang worked as a Senior Research Associate in the School of Computer Science at Cardiff University since 2004. Before working at Cardiff University, he developed many large software systems in several companies, as technical leader or department manager. He obtained his Ph.D. in Computer Science from Zhejiang University in 2003, Masters degree from Hangzhou University in 1984 and Bachelors degree from Nanchang University in 1982.
