Research On P2P Network Information Monitor Technology Based On Multicore

With the rapid development of Internet, the network has become an important source ofinformation for human. There are a large amount of information dissemination in the P2P(Peer-to-Peer) network every day, which has become an important part of the Internet. P2Pnetwork provides effective and rapid transmission for bad resources because of decentralization,and it’s difficult to manage. How to effectively monitor theP2P network is the current directionof research.The paper studies the P2P network information monitoring technology Based on theanalysis of the P2P network packet protocol, and realizes an efficient implementation of P2Pnetwork information monitoring system for the high-performance Tilera multi-core equipment.The main work of this paper is as follows:(1) The design and implementation of monitor mode based on Tilera multi-core processors.The paper designs the strategies of data process flow according to the characteristics ofmulti-core and monitoring process; allocates the cores based on the data processing speed ofeach small step, attempts to perform to optimum level.(2) We monitor the keywords or hash value of files repeatedly according to the systemneeds, modify the routing storage mechanism, and propose a routing table maintenance strategybased on LRU. The main idea is to make the node with monitoring results can have a greaterpriority in the next monitoring. The experiments show that such modifications affect themonitoring results within reasonable limits, and significantly reduce the query hops.(3)The paper designs database and client for this system, so that the client user can easilyquery the monitoring results, add, delete and modify monitoring keywords, observe the runningstate of system.
