On Assuring Survivability of Network Operator’s Services in Evolving Network Environment

Abstract

At the awakening of the 5G network, efforts of operators and vendors are being put in achieving understandable reliability of services in evolutionary network. The increasing users' requirements with regard to the received service jointly to the evolving networking environment have introduced many challenges to service reliability. If the network operators will be not able to offer required quality services even under changing conditions, the customers will lose quickly trustiness in those services. In this case, the current services will difficultly survive to the introduction of thousands of new services appearing with 5G network. How to maintain high quality services regardless of the variability of the underlying network is an interesting research issue for network operators. In this paper, we present a system for monitoring the quality of services offered by the network operators, as well as the quality of experience perceived by end customers. The system will be managed by the network operators, service providers and content providers at their premises. We tested the monitoring system in video on demand service.
