通信数据网业务性能分析

Communication data network business performance

为解决綦南电力通信数据网关键业务存在延迟波动、甚至存在业务中断风险的问题,在现有网络性能测量理论和方法的基础之上,对綦南广域骨干网的流量分布图、端到端可用带宽、网络收敛比等网络关键性能参数进行了测量。另外,介绍了一种基于VPS原理的端到端瓶颈带宽测量方法,尽可能扩大相邻两次网际控制报文协议(ICMP)探测数据包的变化量,削弱噪声对往返时间(RTT)值的影响,实践证明该方法测得的瓶颈带宽值更接近真实值。最后,基于綦南网络性能测量结果,分析网络的性能瓶颈及网络中存在的问题,预测了十三五末的带宽需求。

In order to solve the problem of delay fluctuation and even the risk of business interruption in the key business of Qinan power communication data network,the key performance parameters such as traffic distribution map,end-to-end available bandwidth,and network convergence ratio of the Qinan power grid s wide-area backbone network were measured.In addition,based on the VPS(Variable Packet Size)principle which the variation of adjacent two ICMP(Internet Control Message Protocol)probe packets is expanded as much as possible and the influence of noise on the RTT(Round-Trip Time)value was weakened,an end-to-end bottleneck bandwidth measurement method was introduced.Practice has proved that the bottleneck bandwidth value measured by this method is closer to the true value.Finally,the performance bottleneck and the problems in the network are analyzed,and the bandwidth demand at the end of the 13th Five-Year Plan was predicted.The relevant conclusions can scientifically guide the network planning and construction of the 13th Five-Year Plan and further guarantee the communication quality of the power communication data network.
