某中学校园网即时通信系统的研究与开发.pdfVIP

摘 要 摘 要 随着信息技术的发展，计算机和网络已经成为学校不可缺少的教学辅助工具。然而， 目前广泛使用的个人即时通信技术在很多方面不适合在学校的教学环境中使用，因此， 本文针对所在学校的实际情况，研发了一个即时通信系统，以提高该校的教学和管理效 率。 论文介绍了即时通信系统的发展背景和研究现状，并概括了即时通信系统的相关理 论及技术；采用目前广泛应用的网络关键技术，设计了一个整合P2P （对等连接或对等 网络）模型和C/S （客户机/服务器）模型，支持TCP协议和UDP协议的即时通信系统。 从需求分析、系统设计、详细设计等方面对系统的设计过程进行了论述，并对该软件的 开发进行了较为全面的介绍，实现了一个集文字通信、在线信息、文件传输于一体的即 时通信平台，满足了教师的日常业务要求；最后，总结了研发的工作及经验，对以后某 中学校园网即时通信系统在使用中的完善进行了规划。 关键词 即时通信 中小学校园网 P2P C/S TCP UDP I Abstract Abstract In the wake of developments in information technology,computer and network have become necessary assistant-implements for school’s teaching. But Personal Instant Messaging (PIM) extensively used at present is unsuited to teaching environment in school.So, in view of the truth in our school, I developed a Campus Instant Messaging (CIM) System in this paper to improve teaching and management efficiency for this school. The development background and the present situation of Instant Messaging was stated at the beginning of this paper, then the related theories and technologies are introduced. CIM adopts the wildly used network key technology, integrates P2P (processing to processing) model and C/S (client/server) model, supports TCP and UDP protocol. Then the paper expounded demand analysis, system design and implementation in details and finally completed the CIM platform which integrates text communication, online messageing and file transmission, and all the teaching requriements are satisfied. The last part of the paper summerised the design and developing work and experisence, and gave the perfecting plans in the usage of CIM. Keyword
