Design And Implementation Of Data Forwarding Mechanism For Power Delay-Sensitive Services

In order to ensure the efficient and stable operation of the power system,intelligence has become an important trend in the development of power grids.As an important infrastructure of the smart grid,the power communication network undertakes the important function of ensuring the stable and reliable operation of the power grid.With the continuous improvement of the level of informatization and intelligence,the scale and structure of the power system have become increasingly large and complex.At the same time,the types of power transmission services and data traffic have also experienced explosive growth,and the real-time nature of business control information is constantly being more stringent.the contradiction.Since the transmission requirements of these delay-sensitive services have exceeded the carrying capacity of the traditional power communication network,in order to ensure that the data can be delivered within a limited delay range and meet the requirements of low delay,low jitter,and no congestion for power data transmission It is urgent to design an appropriate data forwarding mechanism for the transmission of delaysensitive services in specific scenarios to meet the needs of stable,reliable and safe operation of the power system.At present,the methods proposed for data forwarding in high-latencysensitive scenarios have some shortcomings.When the scale of transmission business and data is large,the solution efficiency of these methods is low,which makes it difficult to meet the scheduling requirements.On the other hand,these methods often ignore other aspects of the network indicators,such as the optimization of network resource utilization,while optimizing the delay.In addition,these methods often perform indiscriminate and the same degree of delay optimization for all services,while ignoring the differentiated transmission requirements that different services may have different delay sensitivity levels.In view of the above problems,this paper studies the data forwarding mechanism of power delay-sensitive services in specific scenarios.The specific work is as follows:1)A time-slot scheduling algorithm for delaysensitive service data forwarding is proposed for large-scale scheduling requirements.By designing a topology pruning strategy,unnecessary constraints are reduced and the scheduling model is simplified,which solves the problem of large scale of network topology.In addition,a flow grouping strategy based on spectral clustering reduces the scheduling solution time and ensures a high scheduling success rate.The algorithm avoids the impact of the network topology scale and traffic scale on the scheduling response speed,and can better meet the large-scale scheduling requirements compared with similar algorithms.2)A data forwarding mechanism based on deep reinforcement learning is proposed to achieve limited delay requirements.According to the delay-sensitive requirements of different levels of the business,the classification of business traffic is completed,and an adaptive dynamic routing mechanism is implemented with the goal of improving the utilization of network resources.and resource utilization to complete data forwarding.This mechanism comprehensively considers delay requirements,network status and resource usage,and can complete the delivery of data packets within a limited delay.Compared with similar mechanisms,it can better meet the differentiated delivery delay requirements of different services and improve Utilization of network resources.Based on the above research work,this paper also designs and implements a power delay-sensitive business data forwarding simulation verification system.Firstly,the demand analysis is carried out,then the overall architecture of the system is designed and each layered structure is described.Finally,the system is divided into multiple modules,which provide functions such as creating network topology,creating transmission task sets,and data forwarding simulation.Researchers can use this system to complete the simulation of the power delay-sensitive business data forwarding process by importing self-defined external algorithms,and then compare the performance with the built-in algorithms of the system.The system is a general simulation system for the data forwarding process of power delay-sensitive transmission services.Therefore,it can avoid the need for researchers to build a complex network and build a large-scale transmission task set,and to a certain extent reduce the development of simulation systems by researchers.Pressure,so that they can focus more on researching more efficient data forwarding algorithms.According to the transmission requirements of power delay-sensitive services,this paper studies and implements a data forwarding mechanism oriented to delay-sensitive characteristics.Then according to the mechanism,a simulation verification system is designed and implemented to meet the simulation verification requirements of the power delaysensitive business data forwarding process.
