Resource Allocation for Network Slices with Delay-Sensitive Multimedia Services

Abstract

For ubiquitous delivery, multimedia services have resorted to 5G networks in which network slicing is an indispensable part to fulfill the end-to-end performance guarantee for delay-sensitive multimedia services. Coexisting with other 5G services with dynamic varying traffics makes resource allocation a challenging issue for performance guarantee. This paper formulates a resource allocation model to construct the relationship between network slice instances and substrate networks, and a delay optimal resource allocation problem considering backhaul capacity and bandwidth constraints is proposed. Numerical results reveal that the proposed scheme guarantees the delay performance of the delay-sensitive multimedia slices with the variation of traffic.
