由于5G技术预计将影响移动的网络和相关的生态系统,因此对服务质量的适当保证可以最大限度地提高虚拟网络功能(VNF)和网络服务(NS)的能力。这意味着利用服务水平协议(SLA)来确保以高效和可控的方式提供NS。然而,在这种多模式环境中确定资源供应策略的复杂性以及各种VNF和NS的特性和属性导致定制SLA没有考虑5G环境的所有方面。在本文中,我们提出了一个SLA管理框架,映射高层次的需求表示的用户,低层次的资源网络参数,以提高服务提供商的能力,以满足相应的SLA承诺。此外,我们考虑一种动态SLA模板生成机制,其中包含为每个服务提供商量身定制的初始服务级别目标(SLO)。
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'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.
