Performance monitoring challenges in HFC networks

Nowadays, high quality service is expected from internet providers. Performance monitoring is a key tool in network maintenance and in meeting customer expectations. Network operators are faced with many challenges when it comes to performance monitoring. This paper analyzes key challenges in HFC (Hybrid Fiber-Coax) networks performance monitoring. Special attention is given to HFC network and its components that are used for performance monitoring. We propose list of metrics that need to be monitored in order to extract the quality information about a HFC network condition. The goal of this paper is to give a survey of challenges during performance monitoring in HFC networks and to propose Big Data as a solution to these challenges.
