AIn the current 5th Generation (5G) networkingparadigm, the enforcement of Service Level Agreements (SLAs)is a non-trivial measure to ensure the scope and the qual-ity of services and standards between tenants and serviceproviders (SPs). On top of this, Secure Service Level Agree-ments (SSLA) are introduced to ensure that SPs deliver themost critical and required security-related standards […]

The global view enabled by a Software Defined Network (SDN) architecture allows us to observe the contribution of each congested router to the overall Mean Opinion Score (MOS) degradation of a VoIP service. Thus, when a number of routers in the path may add to the MOS degradation, the SDN controller can quantify the contribution […]
