With the proliferation of Ethernet as a technology to connect traffic controllers, video surveillance camera's and other intelligent end devices (IED's), comes the need to build mission critical fault tolerant networks. This paper discusses the application of Rapid Spanning Tree (RSTP) to the construction of robust intelligent transportation systems (ITS) networks. The paper will review the differences between traditional Spanning Tree and Rapid Spanning Tree. Practical examples will be provided to help the audience better understand the need and use of Rapid Spanning Tree. Guidance will be offered to help in the design of networks requiring redundancy and failover.
