摘要:本发明请求保护一种适用于WIA-PA网络的IPv6报文传输系统及方法,在协议结构方面,在WIA-PA协议结构中加入互联网层和传输层。在帧结构方面,根据IPv6报文重新设计了网络层帧结构。在地址分发方面,采用网络管理者在设备入网过程中分发IPv6地址或前缀的形式,同时设计了五种IPv6网络层命令帧。在IPv6报文传输格式方面,根据设备获取IPv6地址方式的不同在适配层设计了相应的报文传输格式。在地址转换方面,设计了IPv6地址与WIA-PA网络地址的转换方法。该发明实现WIA-PA网络支持IPv6报文的传输,对进一步完成WIA-PA网络与基于IPv6的互联网之间的互联互通奠定了基础。

主权项:一种适用于WIA‑PA网络的IPv6报文传输系统,包括应用层、网络层、数据链路层以及物理层,其特征在于,还包括位于应用层和网络层之间的传输层,而且所述网络层还包括互联网层及WIA‑PA网络层;所述互联网层位于网络层的上层,相应的WIA‑PA网络层位于网络层的下层;其中应用层:主要定义了通信服务,采用WIA‑PA标准应用层协议,以支持工业环境中分布式应用的多个对象之间的通信,其中数据通信服务主要包含三种类型的通信模式:客户端/服务器通信模式、发布/订阅通信模式和报告通信模式;传输层采用UDP协议,其提供介于网络层和应用层之间的服务,同时完成UDP报文的封装和解析、UDP连接的建立和销毁;网络层分为网络层上层以及网络层下层,其中网络层上层为互联网层,其由IP层和适配层组成,IP层用于对IPv6报文进行封装、地址解析、提供移动性支持,同时无状态地址自动配置也在该层实现,适配层完成IPv6帧头压缩机制以及消息值的填充;网络层下层为WIA‑PA网络层,其为WIA‑PA标准网络层,同时用于完成MESH子网的路由以及寻址;数据链路层以及物理层采用基于IEEE802.15.4标准,其中数据链路层主要负责无线射频信道的访问、设备的入网,物理层则完成无线射频收发器的启动和终止、能量探测、信道选择。
