报纸网络数据无损压缩安全传输系统研究

Study on Secure Data Transmission System with Lossless Compression for Newspaper Network

针对报纸数据网络传输中存在的技术瓶颈和安全问题,提出并建立了一个具有SSL安全通道、无损压缩、数据库备案、图像预览、自动重连以及任务续传等功能的报纸网络数据传输系统。论文针对单客户端对单服务器、多客户端对多服务器、自动重连、任务续传等4种模式进行了仿真实验。结果表明,应用本文提出的网络数据传输系统,CPU占用率不超过20%,系统内存占用一般不超过500K,网络带宽占用率不超过55%,且通信双方是在拥有有效证书的前提下进行数据交换,有效确保了通信安全。系统在数据库的支持下,能够适应报纸网络版的需求,为报纸网络版的发展提供技术保证。

Due to the technical bottleneck and security problems in newspaper data transmission, a new data transmission system with the functions of SSL secure channel, lossless compression, database record, preview of image, auto reconnection and continuing uploading was put forward and set up. Aiming at four modes, which were signle client to single server, multiple clients to multiple servers, auto reconnection and duty continuing uploading, a simulation experiment was carried out. The results showed that applying the data transmission system suggested in this paper, the CPU occupation rate was not more than 20%, the system RAM occupation generally was not more than 500K, the network broadband occupation rate was not more than 55%. The successful data exchange was on the premise of both communicators＇ possession of valid certificates which effectively guaranteed the secure communication. With the support of database, the data transmission system was well applied in newpaper of network version as a vital techniqual assurance.
