Toward Preventive Network Service Management by Neural Networks
Taichi Kawabata, Takashi Kurimoto, Kimihiro Mizutani · 2018
In this paper, we've explored the possibility of expecting/avoiding degradation of network service performance of Network function virtualization (NFV) by long-term monitoring of hardware and network performances, and adjusting resource assignments of VNFs by preventive management based on Neural Networks (NNs). We've constructed an experimental network service, periodically inserted the specific amount of stresses to the hardware and networks systems, and let the NN learn the long-term trends of service performance changes, then try to adjust VNF resource assignment based on NN's expectations. We evaluate and discuss the results of our experiments.
