目前RSS feeds的传输方式会导致大量重复传输,并且现有的RSS应用缺乏对RSS频道的有效管理的机制,文中提出了一种用DCD协议传输RSS feeds的方法,设计了利用DCD传输RSS feeds的封包格式,描述了其传输方式和传输流程,经过对典型RSS应用场景的模拟和理论计算,在对两种传输方式进行分析和比较后,得出了使用DCD协议传输的方法可很好地解决RSS feeds传输的及时性和传输效率问题的结论,并且提出了使用DCD协议频道管理交互流程来管理RSS频道,从而增强了RSS频道的可管理性.%The current solution of delivering RSS feeds results in great amount duplication and RSS channels lack efficient management in RSS application. This paper presents a distribution system of delivering RSS feeds over DCD protocol, designs the package model, and describes its delivery method and procedure. Compared with the current solution, delivering RSS feeds over DCD protocol can eliminate duplication and delivery content in time. In addition, this paper presents a method to manage RSS channels through some related transactions and messages of DCD protocol, which can enhance the RSS channels' management.
