Resource control of access networks responding to a dynamic change in application requirements

Access network systems are studied to accommodate a variety of services and applications using next-generation communication systems, e.g., 5th Generation Mobile Communication System (5G) and Beyond5G. These communication systems have architectures and mechanisms designed to ensure communication quality other than mere traffic capacity, i.e., high reliability and low latency. However, in terms of the usage of network systems for various applications, it is necessary to consider a wide range of usage conditions, such as time and location of network connection. In this case, the important network requirements are establishing control methods that span different networks and control schemes that can respond to dynamic changes in the usage requirements.Authors’ previous research focused on controlling optical access networks that can be controlled in common for different networks, generating traffic models focused on 5G, and studying resource control schemes for optical access networks designed to carry 5G traffic.In this study, authors take on the challenge of responding to the dynamic requirements changes at the service and application level. In particular, the authors propose a new resource control method and a system configuration that enables integrated control of wireless and wired networks. One of purposes of the proposal is achievement of network resource allocation function that can follow traffic fluctuations caused by the movement of mobile entity carrying terminals. The authors evaluate the effect of adding terminal mobility information to the resource control of the optical access network to improve the responsiveness to the traffic fluctuations.
