Real-time Monitoring Technique Using SFC Classifier in NFV Environment

Network services which handle large-scale traffic require stability and security for the network. Traffic management for efficient traffic processing is also becoming an important issue. NFV (Network Function Virtualization) architecture has been developed to provide a flexible and effective framework to handle this issue and SFC (Service Function Chaining) technique which can configure a single network service by combining network traffic with requirements has been studied. In this paper, we propose a monitoring technique using RCC (Recyclable Counter with Confinement) based SFC classifier for efficient traffic management in SFC. The proposed technique can manage network security functions efficiently for abnormal traffic changing in real time and makes managing traffic better.
