Customized power 5G/B5G communication access method based on power business QoS flow mapping

Abstract

The invention relates to a customized electric power 5G / B5G communication access method based on electric power business QoS flow mapping. The method is technically characterized by comprising the following steps: capturing original business data packets at each communication access point through a network packet capturing tool; pre-processing unclassified power communication data in the service data packet to obtain data convenient for power service flow identification, and classifying the power communication data; performing port matching according to the registered port list, and identifying the coarseness of the power service flow; source and destination addresses, a communication protocol and data packet length information are obtained through a deep analysis data packet detection technology; power traffic is identified based on port and traffic behavior and different QFI values are allocated for power QoS flows in combination with QoS latency indicators. According to the method, the influence caused by hierarchy differentiation can be avoided, the specific communication rigid QoS requirement generally possessed by power system services is met, a power QoS flow mapping mechanism based on B5G is perfected, and a basis is provided for service division of power communication delay calculation.

Description

technical field [0001] The invention belongs to the technical field of 5G / B5G communication, and relates to a 5G / B5G communication access method, in particular to a customized power 5G / B5G communication access method based on power service QoS flow mapping. Background technique [0002] The wireless communication technology represented by 5G has significant advantages in the research of power multi-agent fusion network, and the power wireless communication system will also become the development trend of power communication system. The communication network architecture system usually consists of an access network, a bearer network, and a core network. [0003] The power B5G communication fusion system is a complex network composed of interdependent power grids and communication networks. This interdependence is reflected by the coupling between power nodes and communication nodes, such as figure 1 shown. Power nodes composed of physical equipment such as generators, trans...

Problems solved by technology

[0004] At present, QoS mapping involves multi-layer mapping. Since the packets transmitted by different layers and the protocols used for communication are not the same, the QoS mapping mechanism at the bottom layer cannot be directly applied to the QoS configuration at the upper layer.

For example, the GOOSE and SV packets located on the second layer in the substation generally have a higher priority VLAN tag obtained according to IEEE 802.1Q, but they cannot correspond to the DSCP value set by the IP packet on the third layer network

For complex power systems involving multi-layer cascading, QoS configuration considering priority can become complicated
