摘要:
TR069的整体架构由客户终端设备和自动配置服务器ACS构成,其中CPE部署在私网环境下,ACS服务器则部署在公网环境下。当ACS服务器利用TR069对CPE进行远程管理时需要主动发起连接,由于网络地址转换会使得CPE的网际协议IP地址发生变化,从而在公网环境下的ACS无法直接访问CPE,这会给管理人员带来很大的麻烦。NAT会话穿越应用程序技术可以实现私网穿越从而解决这一问题,但是STUN技术的缺点是用户数据报协议不可靠且会重传丢包,还依赖上层路由的网络地址转换规则时间,因此设计并实现了一种基于可扩展通信和表示协议的TR069的反向连接的私网穿越方案。该方案采取简单的服务器/客户端架构,采用CPE和ACS作为XMPP客户端的方式,它的特点在于使用传输控制协议进行传输,由于TCP比UDP连接更可靠,效率更高,因此在私网穿越方案上,同样的条件下,使用XMPP技术的TR069的主动连接成功率比使用STUN技术要高,丢包率比STUN技术要低,ACS调用远程重启方法成功率比STUN技术要高,说明了在CPE与ACS的通信质量上,基于XMPP技术比基于STUN技术的TR069私网穿越方案更佳。

摘要:
针对线上教学师生之间互动不足,缺乏教学反馈,设计开发了基于Android平台的教学即时通信系统。该系统以开源框架为基础进行二次开发,主要由即时通信服务器、智能作业辅助批改、中间件和Android客户端等模块组成,既能拥有系统自主控制权,确保数据安全,又能为师生定制功能。其中Openfire二次开发实现信息中心功能,IAHC将学生作业进行分词存储标注,为教师提供清晰的批改思路,Smack将操作封装成XMPP底层协议,Android客户端为师生提供可视化界面。目前系统已经开始测试运行,为师生提供了便利的沟通平台。

摘要:
由于网络通信过程经过很多节点,所以节点之间信息的流转会存在很多安全隐患.本文通过对XMPP协议(Extensible Messaging and Presence Protocol,中文全称:可扩展通讯和表示协议)通信原理以及特点的研究,采用C/S架构,针对目前通信软件消息传输安全性低、文件传输大小受到限制等问题做出了一系列改进,首先将消息实体进行加密,防止明文消息泄露;然后对群文件采用分类上传实时刷新的办法,同步更新对应类别的文件列表;最后采用FTP协议解决了XMPP协议离线文件传输的问题,设计出一款安全性高、方便快捷的办公软件.

摘要:
The application of IEC61850 in the power distribution automation can solve the problem of the information model transmission,and reduce the workload of debugging and maintenance caused by distribution terminals accessing to the power distribution master station.In order to accommodate the complex structure of distribution automation communication network and coexistence of multiple communication media,XMPP (eXtensible Messaging and Presence Protocol) is used to transmit IEC61850 information.With the open source program Gloox taken as an example,services of IEC61850 such as association,directionary access,data report are realized by XMPP.With Openfire taken as XMPP server and power distribution master station and remote terminal unit as XMPP clients,an experimental system is built to verify the availability and real-time performance of XMPP mapping.%IEC61850应用于配电自动化可以解决信息模型传输的问题,减少配电终端接入配电主站带来的调试和维护的工作量.为了适应配电自动化系统通信网络结构复杂、多种通信介质并存的特点,研究了采用可扩展消息和在线表示协议(XMPP)传输IEC61850信息.以开源程序Gloox为例,采用XMPP完成了IEC61850的关联服务、目录访问服务、数据报告服务.以Openfire作为XMPP服务器,配电主站、配电终端作为XMPP客户端,搭建了试验系统,验证了XMPP映射的可用性和实时性能.

摘要:
传统的XML压缩算法对XMPP通信中产生的XML数据压缩虽然能达到很高的压缩率,但是还有改进的余地,文中利用XMPP通信中产生的XML数据特点、社区矫正通信应用场景时产生和使用的数据具有相似性的特点对已有算法进行了优化;另外,还对传统压缩算法大多是针对英文,未考虑中文的特点做了相应的改善,使其更好地压缩中文信息.结果表明,改进后的压缩算法相比传统压缩算法,在社区矫正通信系统中压缩率更高.%The traditional XML compression algorithm can achieve a high compress ratio on the XML data generated in XMPP communication,but there is room for the improvement.In this paper,the traditional compression algorithm is optimized by using the characteristics of XML data generated in XMPP communication and the similarity of data generated and used in community correction communication application scene.In addition to the traditional compression algorithm is mostly for English,it did not consider the characteristics Chinese,the paper proposes a method to do a corresponding improvement to make it better to compress Chinese information.The results show that the improved compression algorithm is better than the traditional compression algorithm in community correction communication system.

摘要:
桌面网格是灵活地利用互联网上大量PC资源的闲置时间的计算能力去完成计算任务。对于桌面网格系统,如何为非专业用户提供更美观易用的网格终端,如何保证作业既能充分利用资源又不过度消费资源,以及如何从外部访问无独立IP节点的资源等是亟待解决的问题。本文介绍了一个新的桌面网格系统CROWN Home,给出了针对上述问题的一种解决方案。CROWN Home利用RCP技术封装了网格服务容器,利用J2SE 5.0中引入的对JAVA平台的全面监控与管理,构建了一种资源消费控制框架来解决消费控制问题;利用SOAP和XMPP绑定的方式来解决元独立IP节点的资源访问问题,并且通过实验对解决方案的效率和可行性进行了评估。实验结果表明资源消费控制框架对于CPU等消费控制的准确度以及进行资源消费控制所增加的系统开销是可以接受的;SOAP与XMPP绑定所带来的传输效率的降低也是在可接受的范围内。
