In this paper , the realization of two - level network is to adopt distributed control method . the first level is to be composed by the monitoring computer , the rs - 485 and the intelligent coins selector , mainly completes collection and control of the parameters of the field . the long - distance computer corresponds with monitoring computer through internet and has done the detailed explanation the communication of the two - level network is explanted in detail 两级网络化的实现是采用集散控制方式,第一级是由pc机、 rs - 485总线和智能投币器组成,并给出了相应的通信协议, pc机能够向网络中的任意一台智能投币器进行硬币总额查询;当有新的投币器加入网络时, pc机能够向新投币器写入地址和币型参数。
Meanwhile , improvement of the algorithm is brought out to improve the performance of the analysis and adapt various network environments . major works of the author : 1 . study of ipv6 and ids ; 2 . study and analysis of the precedent ids management system ; 3 . describe the system with object - oriented pattern ; 4 . study and implementation of network flux analysis 。 作者在本论文过程中所做的主要工作如下: 1 .对ipv6和ids的学习和研究; 2 .对旧有ids管理系统进行了研究和分析; 3 .将ids管理系统核心部分进行改造,用面向对象的方式描述整个系统; 4 .在改造后的系统中加入网络流量特征分析模块。
