摘要
SIP相比H.323具有灵活和扩展性好等优点,因此基于SIP构建的视频应用系统越来越多的投入到实际应用当中。针对大型企业"分布广、层级多"的特点,本文研究并设计了一种基于SIP的大型企业可视化指挥调度系统。本文阐述了系统的体系结构、多平台融合方式、组网方式、安全机制以及功能特点,有效地解决了系统多平台通信和多级联网的问题,并探讨了SIP下安全保障问题,满足日常安全生产和应急指挥调度的需求。
Compared to H.323,SIP is more flexible and easy to expand,so SIP-based video applications system is more and more used for practical applications.A SIP-based visualization commanding and dispatching system is studied and designed for widespread and multi-level large enterprises.This paper describes the architecture of the system,the method of multi-platform integration,the type of networking,the security mechanisms and other features.Multi-platform communications and multi-level networking issues of the system are solved effectively,with security discussed as well.It meets the demand of daily security production and emergency commanding and dispatching.
