Problems solved by technology

However, in the network topology of real substations, when the real-time traffic is uninterrupted, these methods can only locate very simple problems, and are helpless for problems such as packet loss, error packets, and large delays.
[0005] Network factors such as switches are added to the power system in the network mining and network hopping environment. The data transmission path is not as intuitive as in the traditional power system. Once the link fails, it is difficult to find the cause and failure

Embodiment Construction

[0018] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 A schematic flow chart of constructing a forwarding path for the present invention, the method comprises the following steps:

[0020] Step 101: listening to data packets in the incoming direction: the switch extracts the port device identifier to form a forwarding table in the incoming packet direction;

[0021] Step: 102: Listen to the data message of the outgoing direction: the switch extracts the port device identification to form the outgoing packet direction forwarding table;

[0022] According to the above two steps, the switch forms the forwarding table of the incoming packet direction and the outgoing packet direction of each port. The attributes of each node in the forwarding table include direction, port, source MAC, virtual local area network number (VLAN) and application identifier (APPI...

Abstract

The invention relates to a method for constructing a forwarding path in an electric power system. A port bidirectional forwarding table is constructed by listening to incoming and outgoing data messages of a port, and then a forwarding path inside a switch is constructed through a network management system to finally form a network-wide forwarding path. Network forwarding path. The invention overcomes the shortcoming that the topological structure needs a long time to be stable, and makes up for the defect that the two-layer switch cannot monitor message forwarding in real time, so that network faults and mutation time delay problems can be quickly located.

Description

technical field [0001] The invention belongs to the technical field of power system utilization, relates to an intelligent substation process layer communication system and method, and in particular to a method for constructing forwarding paths in a power system. Background technique [0002] With the gradual maturity and deepening of the implementation technology of intelligent substations, the application and implementation of intelligent substations has developed from the initial station control layer and interval layer to the process layer. The emergence of the process layer is an important feature that distinguishes intelligent substations from traditional substations. , especially the application of electronic transformers and intelligent switches is gradually mature, the design, installation, commissioning and operation and maintenance of substation devices will bring about profound changes, and the comparison between the final construction results and the expected dra...
