Using XML Compression to Increase Efficiency of P2P Messaging in JXTA-based Environments

By Montréal Québec, Brian Demmings, Gregory Leighton, Tomasz Müldner and Andrew Young


P2P [Peer-to-Peer] systems use messaging for communication amongst peers, and therefore the efficiency of messaging is a key concern for any P2P environment; particularly environments with a potentially large number of peers. One of popular representations of a P2P system is JXTA, which uses XML-based messaging. In this paper, we describe how the use of XML compression can increase efficiency of P2P messaging in JXTA-based environments. In the proposed solution, message elements containing XML data are compressed using an XML-aware compressor. Our design can be used not only for compression but also for other kinds of encodings of XML data, such as encryption. Experimental results demonstrate that our compression technique results in a substantial decrease in message transport time along with a corresponding decrease in the size of messages. Therefore, the application of XML compression for messaging in JXTA-based P2P environments results in an increase in the efficiency of messaging and a decrease in network traffic.
