QoS-Aware Inter-Domain Connectivity: Control Plane Design and Operational Considerations

Scenarios related to 5G and beyond give rise to a
high degree of heterogeneity in terms of applications, services,
and user expectations as well as more demanding QoS require-
ments with an end-to-end scope that can cover multiple operator
domains. In this work, we design an inter-domain component
that addresses the control plane challenges of establishing such
end-to-end connectivity in a scalable, efficient, and automated
way. Furthermore, we provide insights into operational aspects
by investigating to which extent different traffic aggregation
mechanisms can be used to benefit from economies of scale while
meeting QoS constraints.
