With the rapid development of the Internet , Web huge amount of information circulating in the network , the current page information to obtain the actual demand , this paper expand the study and the realization of a distributed WAN website web - based information acquisition system . Designed in this paper describes the structural design, including the hardware architecture and software modules into a WAN - based distributed web crawler . This paper analyzes the key technology for distributed web crawler solution , focused on solving the distributed nodes work together , task allocation, among others , to solve the key technologies for distributed web crawler , a have robustness scalability , configurability distributed network reptiles, and careful analysis of such a distributed web crawler . This is the thesis of innovation . Finally , the web crawler made ??some tests, including a stand-alone the crawling test and the web crawler application , school website pages crawl test . As well as the effect of actually running a variety of distributed system task allocation method under the guidance of the contrast drawn network performance guidance prediction method for task scheduling method .
