The invention discloses a method and a device for determining a loop network. The method comprises the following steps that first equipment respectively sends a first loop sensing message through ports of the first equipment after the first equipment receives a loop network detection instruction, wherein the first loop sensing message carries an equipment identifier of the first equipment; and if the first equipment receives the first loop sensing message within a preset time through a first port of the first equipment, the first equipment determines a loop network path corresponding to the first port according to the equipment identifiers of the equipment in the first loop sensing message. According to the method and the device for determining the loop network, which are provided by the embodiments of the invention, the whole loop network topology is automatically determined through sensing the loop sensing message, and the manual search and the manual configuration of various nodes of the loop network are not needed, so that the working efficiency and the accuracy are improved.
Description
technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method and apparatus for determining a ring network. Background technique [0002] Ethernet, such as the Internet, enterprise network, and campus network, has become inseparable from people's lives. With the wide application of Ethernet in the field of industrial control, in order to improve the reliability of industrial Ethernet, many research institutions at home and abroad have done a lot of work on network redundancy and fault tolerance. [0003] The Ethernet ring is the simplest network redundancy topology. In a ring network, each network node is connected together by a continuous ring, and any network node has only two adjacent nodes. Generally, a switch acts as the redundancy manager. In the normal state, by blocking one of the ring network ports of the redundant management switch, the entire ring network architecture becomes a linear network, the...
