The Optimization Of PON Automatic Activation System Based On Nginx Load Balance

PON(Passive Optical Network)is a network access solution,which is simple,low-cost and easily maintained.A variety of PON services are provided to customers,such as IMS,WLAN,VPN,Internet broadband,etc.Network data configuration is quite important while setting up the PON line.With PON automatic activation system,engineers would be able to get rid of complicated manual operation.The system translates the electronic order into instructions and then sends them to the equipment management server to activate the PON service.The IT system is not only automatic but accuracy as well.The background of this thesis is the research of PON automatic activation system focusing on optimization.Based on the distributed deployment of cluster,load balancing distribution is the core of this optimization,with cluster parallel processing PON activation task.Among activation service components,process engine plays a management and scheduling role.Message queue is used to exchange information between components in a decoupled and asynchronous communication way.In this thesis,two methods of parallel processing optimization are studied and implemented.The horizontal expansion is to distribute the service request to the cluster through the load balancer,which is processed by multiple programs.This thesis compares different methods of load balancing,and selects Nginx reverse proxy,which is flexible,high performance and low cost.Vertical expansion is to increase the number of concurrent processing procedures to achieve higher performance.In Spring framework,the parameters in the configuration file are set and the concurrent number is adjusted so that the processing efficiency of order activation is improved.For the parallel conflict environment control,this thesis analyzes the lock protocol,sorting and failure-retry execution mechanism.Suggests when the collision probability is low,the optimistic mechanism: polling retry is a more effective method.The PON automatic activation system has greater performance after optimization.Order processing capacity has been increased from 200 sheet per hour to 1000 sheet per hour,which has achieved the aim of the research.
