    <subfield code="a">&lt;p&gt;As the 5G technology is expected to impact the mobile network and associated ecosystems, appropriate guarantees for the service quality can maximize the ability of Virtual Network Functions (VNF) and Network Services (NS). This implies the utilization of Service Level Agreements (SLA) to ensure that the NSs are provided in an efficient and controllable way. However, the complexity of determining resource provision policies in such multimodal environments as well as the characteristics and properties of various VNFs and NSs, results to custom SLAs that do not consider all aspects of the 5G environment. In this paper we propose an SLA Management Framework to map high-level requirements expressed by users, to low-level resource network parameters to improve the service provider&amp;#39;s ability to meet the corresponding SLA commitments. In addition, we consider a mechanism for dynamic SLA Templates generation with initial Service Level Objectives (SLO) tailored to each service provider.&lt;/p&gt;</subfield>
