Research And Implementation Of Measurement And Performance Bottleneck Analysis For Datacenter Network

With the rapid development of cloud computing,large data processing and high performance computing,the traditional network can not meet the requirements of network performance,data center network through high speed link and integrated large exchange of equipment,service nodes and storage devices,can be integrated,configuration,coordination and unified control of various software and hardware resources in the network.The superior performance of the data center network provides the important support and guarantee for the data processing and high performance computing.The performance measurement and analysis of the data center network is of great significance.In this paper,we make study of the data center network measurement and performance bottleneck analysis method,the main innovation points are as follows:1.Analysis of the current network measurement system framework,we proposed a distributed measurement architecture based data center network :DM-DCN,we used a hierarchical structure,and we proposed a series of key mechanisms for data center network measurement,such as the measurement node deployment mechanism based on vertex cover,dynamic configuration of network measurement mechanism and network state based dynamic adjustment and measurement mechanism.2.When the data center network in the initial operation stage or the network topology adjustment,network equipment is not reasonable allocation of network performance bottleneck point of the problem,proposed a network static performance bottleneck analysis method SNBM,can quickly scan the network topology of the exchange equipment to match,and then carry out performance analysis,so as to diagnose the network potential performance bottleneck.3.A performance bottleneck analysis method based on distributed automatic measurement AM-DMPA.This method can combine the network topology generation measurement task set,the next measurement task according to the network current state,and according to the analysis of the measurement results,the performance bottleneck link in the network can be determined.4.The distributed network measurement management system which includes the view layer,the control layer and the resource layer is designed,which is based on the distributed measurement system DM-DCN.Through the visualization component,the management function of the network management personnel to the measurement,monitoring and performance bottleneck analysis of the data center network is realized.The system is tested and run on the Guangzhou Tianhe 2 network.The effect is good.
