Evaluaion of assurance closed loop PoC for achieving scheduled maintenance in telecommunication carrier networks

As an issue for operating and managing virtual network in telecommunication carrier networks, “multi-slice management technology” have been reported, and implementing method of autonomous control loop (closed loop) for virtual network is one of the key topic of it. This article focuses on the reduction of unexpected failures in large scale network, which is one of the major issues in network maintenance and assurance operation. This article proposes a method and an implementation of autonomous control loop (closed loop) that combines Network-AI, NFV orchestrator, virtual network, and cloud technologies. The benefits of the proposed method and the results of the implementation evaluation, including feasibility evaluation result of scheduled maintenance are also explained and reported in this article.
