【摘要】 IGRS(Intelligent Grouping and Resource Sharing)和UPnP(Universal Plugand Play),是当前数字家庭网络领域的两大主流协议。本文从两种协议组成机制的层次结构和各对应层之间的相似及区别入手,对比其寻址、发现、描述、控制等各个方面的特点,抽象出两个协议中相同的基础模块,并分别处理两种协议的不同之处,将两种协议有机融合形成双协议栈。双协议栈实现的目的就是用最小的开销,同时支持这两种主流协议。更多还原

【Abstract】 IGRS (Intelligent Grouping and Resource Sharing) and UPnP (Universal Plug and Play) are the two main protocols in the field of digital home network at the present time. They are designed to make devices in the digital home connect and cooperate more conveniently and intelligently. They are both based on some existed standard protocols, such as HTTP, XML, SOAP, etc. But without proper disposal, a device installed with one protocol cannot communicate with one with another. The reason is that they have different message format and call format. To tackle the differences, we design the Dual Protocol Stack. This paper analyzes the hierarchical structures of the forming components and the similarities and differences in the corresponding layer, compares the characteristics in the process of addressing, discovering, description, control, etc. The Dual Protocol Stack abstracts the same fundamental modules of the two protocols, tackles the differences, syncretizes them to form a separate protocol. To deal with different message format, we design different message modules to send, receive and parse different kind of messages on the network. To deal with different call format, we design to send respective call request messages to different control port. The purpose of the Dual Protocol Stack is to support the two main protocols simultaneously with the minimal spending.更多还原
