摘要
Abstract
With the vigorous construction of the digital new power system,the traditional power communication network is gradually transforming into a more robust,resilient,and multi-service-bearing all-time and all-domain communication network.To address the issue of difficult-to-guarantee deterministic latency for time-sensitive services due to the simultaneous access of multiple types of terminal services and massive data transmission in the all-time and all-domain communication network,a deterministic latency guarantee technology is proposed for all-time and all-domain communication networks based on Time-Sensitive Networking(TSN).Firstly,based on the analysis of the characteristics,importance,periodicity,and latency requirements of various types of services in the all-time and all-domain power communication network,the corresponding service models are established and prioritized.Then,a traffic scheduling mechanism based on TSN perception and shaping is proposed to ensure that the calculation of the gate control schedule meets the deterministic low-latency transmission of time-sensitive flows within the transmission cycle.To achieve the goal of minimizing end-to-end latency,a combined algorithm based on genetic algorithm and tabu search algorithm is employed to calculate the gate control list of time-sensitive flows.The average end-to-end latency is reduced by 15%compared with single optimization algorithm,and the latency jitter of time-sensitive flows is controlled at about 2 μs.This improves the scheduling performance and provides strong support for the stable and safe operation of the all-time and all-domain power communication network.关键词
