“…This helps bridge the gap between the expectations of customers and service providers and facilitate negotiation clarity between stakeholders in the SLA development phase. The studies in [38] and [37] aim to address this challenge using data analytics and artificial neural networks to automatically identify the interdependencies between different parameters. A framework that implements the reverse process is proposed in [85], where the authors address the translation of low-level metrics to high-level SLA terms that are used in cloud service level agreements.…”

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.

“…The primary players are indicated as the Service/Infrastructure Provider, the end-user that could be a developer of VNFs or network services (NSs), or/and the service consumer [15]. The proposed framework employs artificial neural networks (ANNs) and acts as a mediator between the service providers and the end-users [16]. In our case, the NECOS Marketplace approach implements a resource discovery schema leveraging a brokerage model inside the platform.…”

Cloud network slicing can be defined as the process that enables isolated end-to-end and on-demand networking abstractions, which: (a) contain both cloud and network resources, and (b) are independently controlled, managed and orchestrated. This paper contributes to the vision of the NECOS project and relevant platform, that aim to address the limitations of current cloud computing infrastructures to accomplish the challenging requirements of the slicing approach. The NECOS platform implements the Slice-as-a-Service model, enabling the dynamic creation of end-to-end (E2E) slices from a set of constituent slice parts contributed from multiple domains. A challenging issue is to define the facility that implements dynamic slice resource discovery, aligned to the requirements of the slice owner or tenant, over different infrastructure providers. Here, we propose a Marketplace-based approach implementing relevant federated interactions for the resource discovery and we detail its

“…It should be pointed out, that a preliminary description of our work can be found in [14,15,18], where the authors presented an approach for mapping the high-level end-user requirements the low-level policy parameters, and at the same time proposed a mechanism for suggesting the most important QoS parameters to the Service/Infrastructure Provider, in order to achieve better QoS assurance. In the present paper, we are going beyond an isolated SLA management framework, by trying to support business guarantees in the overall lifecycle of NSs.…”

“…Considering the aforementioned set of challenges, in this paper, we are trying to portray an "SLA-Oriented Framework" which targets the profitable provisioning of QoS guarantees, in 5G environments. The proposed approach is based on mapping the high-level customers' requirements to low-level recourse attributes, as shortly described in [14,15]. The proposed Framework adopts an Artificial Neural Network (ANN) approach, making it easily adaptable to different software components like VNFs and NSs.…”

The 5G is the fifth generation of mobile broadband, cellular technologies, and networks that promises a major change in mobility by evolving connected business realities. In such an emerging environment, reliable Service Level Agreements (SLA) and anticipation of breaches of Service Level Objectives (SLO) become compulsory. Thus, guaranteeing the required service quality, while also ensuring efficient recourse allocation becomes a challenge. In addition, 5G networks are expected to provide diverse Quality of Service (QoS) guarantees for a wide range of services, applications and users with a variety of requirements. However, there is an increased difficulty in translating user-friendly business terms into resource-specific monitoring attributes that can be used to manage resources in the 5G core network. To address these gaps, an SLA management framework, enabling QoS provisioning is introduced. The aforementioned framework will be supported by an adaptive monitoring algorithm, which removes the static time interval used in the monitoring system, in order to provide highly accurate information in real time, without the produce of unnecessary traffic to the network. The proposed architecture also incorporates a recommendation mechanism to determine the significance of various QoS parameters in order to ensure that relevant QoS metrics are included in the SLAs, using enriched metadata information from a Network Function Virtualization (NFV) Catalogue.
