Design and Practice of Digital Intelligent Operation and Maintenance Capabilities for Telecom Operators’ Backbone Networks

With the growing scale of operators’ backbone network and the continuous enrichment of carrying services, the business traffic is growing in a massive manner, and the complexity and workload of network traffic operation and maintenance are increasing. This paper aims to support “traffic management’’ and achieve the intelligent transformation and upgrading of operators’ backbone network operation dimension. It studies the automatic and intelligent means of backbone network traffic optimization, innovatively and comprehensively applies real-time route monitoring, network simulation modeling, multi factor combination analysis, network intelligent scheduling and other capabilities to achieve the whole closed-loop traffic automatic optimization scheme. Through practical application in the current network of operators, the traffic optimization cycle has been shortened from manual hourly and daily levels to minute levels, improving operation and maintenance efficiency and user experience, achieving good results.
