“…However, the SLA Manager cannot guarantee the authenticity of the source of monitoring data. Touloupou et al [25] designed a monitoring system that can automatically develop agreements based on each network slice instance and detect any violations and raise alerts. However, the proposed framework can only monitor and manage business assurance in a single network service.…”

Network slicing, as a key technique of 5G, provides a way that network operators can segment multiple virtual logic on the same physical network and each customer can order specific slicing which can meet his requirement of 5G service. The service level agreement of network slicing (NS-SLA) of 5G, as a business agreement signed between the network operators and the customers, specifies the relevant requirements for the 5G services provided by the network operators. However, the authenticity of auditing results may not be guaranteed and the customer’s data may be leaked in the existing NS-SLA audit scheme. In this paper, a blockchain-based 5G network slicing NS-SLA audit model is proposed to address the above problems. The blockchain is applied as a public platform and all the dual monitored service parameters will be stored on the blockchain to ensure the authenticity of data. A trapdoor order-revealing encryption algorithm is introduced to audit strategy, which can encrypt the monitored parameters, realize the comparison over ciphertexts and prevent the privacy of data from leaking. Besides, an NS-SLA audit smart contract is designed to implement the audit task and execute corresponding punishment strategies automatically. We make experiments to exam the cost of the blockchain-based system and the results found clear support for the feasibility of the proposed model.

“…At this point a question arises, regarding what exactly is an SLA. An SLA is a contract between the service provider and the customer, which underlines each party's responsibilities while at the same time defines the performance standards that are to be met by the provider [14]. The proposed SLA Manager can support a) Definition and advertising of the capabilities of network operators in SLA Template forms and b) Agreements creation upon a NS instantiation [16].…”

Software licensing is changing how organizations and individuals use software. Globally, technical and economic needs affect licensing in many ways and thus creating licensing models and techniques that reflect and serve organizations' needs, becomes an increasingly challenge in the Network Function Virtualization concept. While NFV continues emerge, it also becomes increasingly important to monitor and manage software licenses. Therefore, in this paper, a license-based architecture is introduced which aims at linking the Network Services with license models throughout SLAs. Specifically, we have introduced an interconnection between license models and SLAs, in which we aim at an efficient and flexible service orchestration in a beyond MANO SP.

5G and beyond networks will transform the healthcare sector by opening possibilities for novel use cases and applications. Service level agreements (SLAs) can enable 5G-enabled medical device use cases by documenting how a medical device communication requirements are met by the unique characteristics of 5G networks and the roles and responsibilities of the stakeholders involved in offering safe and effective 5G-enabled healthcare to patients. However, there are gaps in this space that should be addressed to facilitate the efficient implementation of 5G technology in healthcare. Current literature is scarce regarding SLAs for 5G and is absent regarding SLAs for 5G-enabled medical devices. This paper aims to bridge these gaps by identifying key challenges, providing insight, and describing open research questions related to SLAs in 5G and specifically 5G-healthcare systems. This is helpful to network service providers, users, and regulatory authorities in developing, managing, monitoring, and evaluating SLAs in 5G-enabled medical systems.
