Design and Implementation of Container-based M-CORD Monitoring System

Since the concept of Software-Defined Networking (SDN) and Network Function Virtualization (NFV) has been proposed, service providers leverage the concepts to provide their services efficiently. Mobile CORD (M-CORD) is a platform to provide 5G network services using containerized VNFs in Multi-access Edge Clouds (MECs) at the central offices of telcos. However, current M-CORD does not include network and resource monitoring functions. In this paper, we present the design and implementation of a monitoring system to help efficient management and operation of the M-CORD platform configured in multi-site. Through this monitoring system, we can monitor the computing resource usages and data traffic load of each VNF container in M-CORD. We conducted experiments on our multi-cluster testbed to evaluate our monitoring system in terms of CPU and memory usage. As a result, our proposed monitoring system has a slight increase in CPU and memory usage, but it was able to perform M-CORD monitoring functions well.
