A decentralised data layer for collaborative End-to-End service assurance
Abstract : This paper proposes a solution for validating an End-to-End service chain built by multiple actors that may not trust each other. We notably introduce a "data layer" powered by a Distributed Ledger (DL, a.k.a "Blockchain") using a Directed Acyclic Graph (DAG). This component will enable all players involved in a network service chain to share trusted and secure performance data, whilst avoiding the participation of trusted third parties. We consider as a driving use case a scenario where resource providers and resource consumers (a.k.a "prosumers") interact together to build on-demand network services. We thus focus on a Cloud-based Radio Access Network scenario and anticipate network disaggregation, allowing the infrastructure to be shared between multiple providers. We show through simulation that the usage of a DAG-based ledger will make the proposed data layer scalable despite the amount of performance data required for monitoring.
