The novel concept of factory-as-a-service (FaaS) allows for the flexibility of the manufacturing process by identifying supply chain and user requirements. To support FaaS, flexibility in networking and cloud services is necessary. This article introduces a secure blockchain-based network slice broker (NSB) to facilitate FaaS, providing secure, cognitive, and distributed network services, and coordinating the work of slice managers and security service level agreement (SSLA) managers.
The novel concept of factory-as-a-service (FaaS) allows the agility of adapting the manufacturing process by identifying the industry's supply chain and user requirements. To cater to FaaS, flexibility in networking and cloud services is a must. 5G network slice broker (NSB) is a third-party mediator that caters to networking resource demand from clients to the service providers. Thus, this article introduces a secure blockchain-based NSB to facilitate FaaS. The proposed secure NSB (SNSB) provides secure, cognitive, and distributed network services for resource allocation and security service level agreement (SSLA) formation with coordination of slice managers and SSLA managers. In SNSB, we introduce a federated slice selection algorithm with Stackelberg game model and reinforcement learning algorithm to compute the real time and the optimal unit price and demand level. We provide an extensive implementation and performance evaluation of SNSB using the slice manager and a custom SSLA manager.
