5G networks will comprise multiple network and compute infrastructure setups at finest fragmentation consisting of multiple disaggregated pools of network, compute and storage resources. Thus, 5G shall provide the means to move from the currently strictly defined, simple, single service models of provisioning connectivity or cloud or software services separately, to more complex "service provisioning" models including a mix of infrastructure resources, network services and even applications, specifically tailored to the specific stakeholder/vertical/end-user requirements. In this context, new SLAs shall be defined along with the SLA monitoring and maintenance mechanisms to be deployed over the distributed/disaggregated 5G deployments resources. This paper provides insights on the 5G network services SLAs definition along with an SLA maintenance paradigm.
