Design And Implementation Of University Search Engine Based On P2P

University network is the basic facility on the construction of school informationlize. It is also an important platform, with which the teachers and students will teach and research. The university network based on P2P save its resource in the various peers with P2P distributed architecture. Besides, the program builds the interest network based on "small word", which means that the scope of the files shared is limited within the university network. So we can make full use of the resource in our university. It also provides an effective solution to the bandwidth occupied in order to reduce the big pressure on our network export. At the same time, it speeds up file transfers between peers.The implementation of university search engine based on P2P using two popular open-source technology - JXTA and Nutch. On one hand, the system builds a common and unified P2P network with JXTA. JXTA provides the dynamic discovery mechanism with ip multicast and the static discovery mechanism with rendezvous peers. It can reduce the waste of the bandwidth. At the same time, it describes and transfers information with XML. The advertisement is saved in the middle peers, which just transfer information. On the other hand, the system builds web search engine based on Lucene technology with Nutch. The aim of designing it is more specific than the most popular search engines (such as Baidu, google, etc.). It just search the university home page and the related links. Web crawling use the breadth-first traversal and allow the server administrator to decide the depth of search, so the system is more effective.
