Flood Discharge Cross-Domain Routing Selection Based on Resource Sharing Equilibrium for Electric Power Communication Network

In order to address the issue of inter-domain blocking phenomena in cross-domain transmission, which results in low processing capacity for burst traffic and inadequate deployment capabilities for large traffic flows, this paper proposes a flood discharge cross-domain routing selection mechanism based on resource sharing balance, referred to as FR-CD. The proposed method is structured into two layers: inter-domain routing and intra-domain routing. The inter-domain routing primarily relies on service classification, which is informed by principles from water conservancy dam management. Intra-domain routing employs an improved shortest distance calculation method, supplemented with bandwidth utilization as a weighting factor to optimize the identification of intra-domain routes. This approach contributes significantly to establishing new pathways within power systems, enhancing both operational efficiency and security within communication backbone networks and access networks. Furthermore., it supports the construction and development of modern power systems.
