摘　　要：达尔文流媒体服务器(Darwin Streaming Server,DSS)是Apple公司开发的开源流媒体服务器架构,可运行于Win-dows,Linux,MacOS等多种平台.本文结合一实际通用应用项目,通过分析DSS的主要工作流程及其开发接口,研究在不改变其服务器核心代码的情况下,为解决大量用户权限管理的问题增添新的用户认证等自定义功能的方法,并对新实现的用户认证与原有的简单认证进行对比压力测试,实验说明该方法可以实现带有权限控制的复杂用户认证,且性能在大量注册用户的情况下有显著提升.Darwin Streaming Server （DSS） is the streaming server developed by Apple Co.ltd,which can work on various platforms such as Windows,Linux and MacOS.Based on the analysis of Darwin Streaming Server processing procedure and modules which constitute the interfaces for further development,the paper studies the method to add new self-defined functions such as user authentication with access control or other functions using modules without changing the kernel code of the server.Finally,a stress test to compare the new and original user access control shows the new method realizes complicated user authentication with access control and improves performance significantly in the case of large number of register users.
