摘　　要：目前智能变电站过程层主要采用以太网组网,但是以太网技术本身具有路径唯一、交换过程不可控等缺陷,极大限制了过程层网络可靠性提升。为克服以太网组网技术缺陷,提出建立基于多链路透明协议(transparent interconnection of lots of links,TRILL)技术的过程层网络。首先,构建简单TRILL网络模型并深入分析TRILL技术原理和通信模型;其次,建立基于TRILL技术的过程层网络组网方案并分析TRILL组网方案的优势;最后,通过OPNET仿真软件构建实验平台,进行TRILL技术组网方案可行性研究。结果表明,基于TRILL技术的过程层组网方案具有流量合理、拓扑收敛快等优势,展现出较强的可行性和适应性。Currently,the process-level network mainly adopts Ethernet network.But Ethernet network has defects such as unique path and uncontrollable exchange process,which restricts the improvement of process-level＇s reliability.The multi link transparent protocol in the process layer network（ TRILL） to overcome the defects of Ethernet network is introduced.Firstly,a simple TRILL network model and study technical principle and communication model of TRILL are established.Secondly,the network scheme of process-level based o of n TRILL is estabilished and analysied the advantage this network scheme.Finally,the feasibility of network scheme through OPNET simulation software is verified.The results shows that process layer network based on TRILL have the advantage of small flow increase,message transmission path traceability and optional,small network construction investment,which provide new ideas for the procss layer network construction.
