基于网络演算的5G承载配网业务失效计算方法
Failure Calculation Method of 5G Bearer Distribution Network Based on Network Calculus
摘要
Abstract
The advancement of 5G technology,with its features of high bandwidth,wide connectivity,and low latency,holds significant implications for the efficient and secure operation of information-based distribution networks.To analyze the risk of distribution network service failure due to transmission delays during network anomalies,this paper proposes a method for calculating the bandwidth threshold of abnormal traffic in distribution networks based on network calculus.Firstly,we establish the service curve of business flows based on the Strict Priority Queuing(SPQ)strategy.Secondly,we construct the arrival curve of switches based on the transmission characteristics of distribution network business flows.Finally,utilizing network calculus,we develop a model for calculating the bandwidth threshold of abnormal traffic in distribution networks.Experimental results demonstrate that when the bandwidth of abnormal traffic is below the threshold,the service quality requirements of distribution network services can be met,thereby providing a theoretical basis for the secure and stable operation of distribution communication networks.关键词
