Slice-Aware Elastic Resource Management

Network softwarisation and network slicing are two important 5G technology enablers. Implementing mobile networks over the commercial data-centres has proven to have considerable benefits. Realising cloud-based mobile networks and serving multiple network slices with different requirements over the same virtualised physical infrastructure are challenging tasks. The IP tsunami and dramatic temporal and spatial variation of traffic demands made the situation worse. In this situation, slice-aware elastic resource management approaches are required to guaranteed the quality of offered services to the slices while minimising the capital and operational expenditure of networks. This paper provides a brief overview on the design guidelines for slice-aware elastic resource management.
