数字家庭中UPnP与IGRS互操作性技术的研究

Research on interoperability technology of UPnP and IGRS protocols in digital home environment

在数字家庭网络中,UPnP与IGRS都能实现不同设备间无缝联接,但这两种协议存在差异,无法互联互通。针对该问题,从寻址、发现、描述、控制、事件几个方面着手,找出两个协议间的联系和区别,然后提出了一种新的方法:基于UPnP与IGRS互操作双协议框架。围绕该框架,详细描述了转换桥、虚设备管理以及UPnP/IGRS设备管理三个模块的实现过程。将基于双协议框架开发的程序运行在PC上,使其与IGRS设备和UPnP设备交互。通过实验结果发现,PC能够发现这两种设备,而且这两种设备间也能够互相发现,共享资源。提出的基于UPnP与IGRS互操作双协议框架能够有效实现这两种协议间的互操作。

In the digital home network environment,UPnP and IGRS can achieve the seamless connection among different devices,but these two protocols are different so that they can’t interact with each other. Aiming at this problem,proceeding from addressing,discovery,description,control and event,the differences and similarities of these two protocols are found out. A new approach called interoperation dual-protocol architecture based on UPnP and IGRS is proposed in this paper. Three modules of conversion bridge,virtual device management and UPnP/IGRS device management are described in detail according to the architecture. The program developed on the basis of the dual-protocol architecture is run in PC,and interacted with IGRS device and UPnP device. The experimental results show the PC can find these two devices,and these two devices can find each other. The resource sharing is realized finally. Therefore,the proposed interoperability dual-protocol architecture based on UPnP and IGRS protocols can achieve the interoperation between these two protocols.
