Design and Implementation of Scalable, Fully Distributed Web Crawler for a Web Search Engine

The Web is a context in which traditional Information Retrieval methods are challenged. Given the volume of the Web and its speed of change, the coverage of modern web search engines is relatively small. Search engines attempt to crawl the web exhaustively with crawler for new pages, and to keep track of changes made to pages visited earlier. The centralized design of crawlers introduces limita...

UbiCrawler: a scalable fully distributed Web crawler

We present the design and implementation of UbiCrawler, a scalable distributed web crawler, and we analyze its performance. The main features of UbiCrawler are platform independence, fault tolerance, a very effective assignment function for partitioning the domain to crawl, and more in general the complete decentralization of every task.

A Scalable, Distributed Web-Crawler*

In this paper we present a design and implementation of a scalable, distributed web-crawler. The motivation for design of such a system to effectively distribute crawling tasks to different machined in a peer-peer distributed network. Such architecture will lead to scalability and help tame the exponential growth or crawl space in the World Wide Web. With experiments on the implementation of th...

Challenges and Design Issues in Search Engine and Web Crawler

Design and Implementation of a High-Performance Distributed Web Crawler

Broad web search engines as well as many more specialized search tools rely on web crawlers to acquire large collections of pages for indexing and analysis. Such a web crawler may interact with millions of hosts over a period of weeks or months, and thus issues of robustness, flexibility, and manageability are of major importance. In addition, I/O performance, network resources, and OS limits m...
