摘要
随着终端个数的增多,呈现(Presence)服务中的点对点订阅会引起数据量偏大、终端频繁订阅等诸多问题。资源列表服务通过订阅列表的方式很好的解决了这个问题。在参考SIMPLE标准的基础上提出一种资源列表业务模型实现框架,详细讨论了列表订阅机制及其设计原理,设计并实现了一种资源列表服务器(RLS)。经过测试,该服务器能正确完成列表订阅,性能良好,很好地解决了终端频繁订阅的问题。
With an increasing number of friends, Peer to Peer subscription in Presence causes a great dataflow and many other issues.The Resource List Service is a very good approach to solve this problem by subscribing to the list.This paper proposes a framework for the implementation of Resource List Service Model which refers to SIMPLE standards.Based on this, the RLS as well as its descriptions are designed.Upon testing the RLS in WAN, the experimental results show that RLS can correctly complete the subscriptions of a list and provide an excellent solution for the frequent subscription issues.
