Blockchain-Based Information Management for Network Slicing

Abstract

Network slicing is the crucial enabler of the new emerging 5G and beyond network generations. It facilitates the facility to compose logical networks over shared physical infrastructures. From the implementation perspective of view, slice isolations and sharing become very challenging. It introduces challenges to provide secure information to the subscribers and enables users to modify and configure the registrations while following the service level agreement. To this aim, we introduce a blockchain as a service, in which the distributed ledger technologies provide security and accessibility to the end-users while removing a third-party involvement. Additionally, it allows tenants and subscribers to manage the slice information as necessary without violating the agreement. The primary advantage of including blockchain in architecture is using it to slice isolation and sharing.
