【摘要】：随着科学技术的不断发展与进步,人们对于通信方式多样化的需求日益增多,融合通信把计算机互联网技术和传统通信技术结合在一起,以音视频通话为基础功能,同时提供了即时消息、具有社交网络服务性质的朋友圈消息、新闻消息推送等业务功能,为用户提供方便、高效、多种方式的通信手段。融合通信系统由客户端和服务器端的控制平台组成。本文对融合通信系统进行了需求分析,明确了对于融合通信系统控制平台的功能需求和非功能性需求,进而对控制平台进行了概要设计。本文对控制平台每个模块的关键问题进行了分析研究,基于Pick-KX算法,设计了带自反馈机制的服务器集群负载均衡算法,在较好的实现了服务器负载均衡的同时减少了成员服务器因进行负载检查而造成的额外负载开销;为了减少XMPP服务器集群网络通信的开销,设计了基于用户属性和一致性哈希算法的用户登录映射策略,并且支持服务器的动态添加和删除;为了保证即时消息的可靠性,设计了消息到达保证策略,通过发送回执和设置消息的生存周期的策略,消除了用户在连接断开情况下,消息丢失的情况;针对融合通信系统数据的结构特点,本文设计了多样化的数据存储和数据响应方案。本文针对融合通信的需求特点,对关键问题进行了分析研究,设计并实现了融合通信系统控制平台,经测试满足功能和非功能性需求,达到了应用目标,并在实际工程项目中得到应用。
[Abstract]:With the development and progress of science and technology, the demand for the diversification of communication mode is increasing day by day. The fusion communication combines the computer Internet technology with the traditional communication technology, and takes the audio and video communication as the basic function. At the same time, it provides the business functions of instant messaging, network of friends with the nature of social network services, news push and other business functions, providing users with convenient, efficient and multi-way means of communication. The fusion communication system is composed of client and server control platform. In this paper, the requirements of the fusion communication system are analyzed, and the functional and non-functional requirements of the control platform of the fusion communication system are clarified, and the design of the control platform is summarized. In this paper, the key problems of each module of the control platform are analyzed and studied. Based on the Pick-KX algorithm, the load balancing algorithm of server cluster with self-feedback mechanism is designed. In order to reduce the overhead of the XMPP server cluster network communication, the load balance of the server is realized better and the additional load overhead caused by the load checking of the member server is reduced. The user login mapping strategy based on user attributes and consistent hash algorithm is designed, and the dynamic addition and deletion of server are supported. In order to ensure the reliability of instant message, a message arrival guarantee strategy is designed. By sending the receipt and setting the lifetime of the message, the message loss is eliminated in the case of connection disconnection, and the structure characteristics of the fused communication system data are analyzed. In this paper, a variety of data storage and data response schemes are designed. According to the requirements of fusion communication, this paper analyzes and studies the key problems, designs and implements the control platform of fusion communication system, and meets the functional and non-functional requirements by testing, and achieves the application goal. And it is applied in the actual project.
