Description
Summary:The fifth generation (5G) of cellular networks shall host a number of tenants and provide services tailored to meet a wide range of requirements in terms of performance, dependability and security. Network slicing will be a key enabler, by assigning dedicated resources and functionalities to meet such requirements, where the isolation between slices, i.e., that a slice may operate without interference from other slices, becomes a core issue. The objective of this paper is to give a thorough insight into the isolation concept, discuss the challenges involved in providing it, and outline the means available to provide various levels of isolation. Fundamental concepts that can be used in further work to build an isolation solution tailored to specific needs. This paper defines important concepts such as the Provider Management, the Tenant Management, and the Means of Isolation in the context of the Isolation Dimensions. The conclusion of the study is that dealing with isolation between slices needs extensions in state of the art on the mentioned concepts, and in how to tailor the isolation to meet the needs in a cost-efficiency manner.
