大型多媒体网络通信中的安全监测平台设计 　　摘 要： 由于受到大型多媒体网络通信中不安全因素更新迅速的影响，导致以往设计出的大型多媒体网络通信安全监测平台监测能力和响应效果均不高。因而，设计监测能力强、响应效果好的大型多媒体网络通信安全监测平台。该平台的监控中心为数据采集模块，数据采集模块利用RTL8019AS控制器采集大型多媒体网络通信中的节点传输数据和通信节点安全状态数据，为处理模块提供统一格式的待测数据。处理模块利用MSP430处理器对待测数据进行安全检测，其与传输模块直接相连。传输模块会对已处理过的待测数据进行错误检测和传输，其处理流程在软件中给出，软件还给出平台功能图。实验结果表明，所设计的平台监测能力强、响应效果好。 　　关键词： 大型多媒体网络通信； 安全监测； 监测平台设计； 错误检测 　　中图分类号： TN926?34； TN915 文献标识码： A 文章编号： 1004?373X（2016）24?0009?05 　　Design of safety monitoring platform used for large?scale multimedia 　　network communication 　　DAI Likun1，2 　　（1.

The monitoring center of the platform is a data acquisition module， which adopts RTL8019AS controller to collect the node transmission data and communication node security status data in large?scale multimedia network communication， and provide the data processing module with the unified format data waiting for detection. The data processing module executes safety detection of the data under test by means of MSP430 processor. It is directly connected with the transmission module which executes error detection and transmission of the processed data. Its processing flow and platform function diagram are given in the software. The experimental results show that the monitoring capability and response effect of the designed platform are perfect. 　　Keywords： large multimedia network communication； safety monitoring； monitoring platform design； error det
