摘要/Abstract

摘要： 为了解决传统即时通讯系统在局域网或企业内安全性不高且效率低下的问题,提出了一种基于改进传输协议的新型即时通讯系统。采用结构为三服务器协调运作管理模式,在多客户端会议过程中融入独特的二叉树形式P2P查找结构。另外,在传统可扩展标记语言之上构建了一种有别于其他任何传输协议的新协议,提高了局域网内部的传输安全性。最后将本文算法与另外两种公共即时通讯系统的定位查找成功率和不稳定指数进行对比,结果显示:新型即时通讯系统具有更高的执行效率。

Abstract: Traditional instant message systems have the shortcomings of low security and inefficiency in LANs or enterprises. To overcome the shortcomings, a novel instant message system with an improved transmission protocol was proposed. The management mode of network structure co-operation of three servers was employed in this system. In addition, a unique form of binary tree P2P lookup structure was proposed in the model of multi-client meeting. Furthermore, a novel protocol based on XML, which is different from any other protocols, was developed in the new system. The new protocol can improve the transmission security. Experimental results show that, compared with other two instant message systems, the proposed system is more steady and efficient in term of location lookup rate.

Key words: computer application, instant message, network security, binary tree, transmission protocol
