摘　　要：即时通信是一类非常实用的网络应用程序,常见的即时通信软件一般采用基于IP网络的客户端-服务器设计方式,这是简单和流行的做法,但存在一些缺点,如单点失效、流量集中和安全问题。命名数据网络是一种以数据为中心的网络,本身具有很好的安全性和多播特性。设计了一款基于命名数据网络的分布式即时通信系统HAHA,避免了单点失效和流量集中的问题,改善了数据传输效率和安全性。在NS3上进行了仿真实验,证明了HAHA软件较好的网络性能。Instant messaging software is a useful network application, common instant messaging software is generally client-server designed based on IP network, it is a simple and popular method, but there are some shortcomings, such as single point failure,traffic concentration and security issues. NDN（Named data networking） is an information-centric networking, itself has a very good security and multicast characteristics. In this paper, a distributed instant messaging system named HAHA is designed, which avoids the problem of single point failure and traffic concentration, and improves the efficiency and security of data transmission. The HAHA shows good network performance in the simulation experiment on NS3 simulator.
