Orchestration of Crosshaul slices from federated administrative domains

With the advent of 5G networks, more dynamicity and flexibility will be needed for the deployment of services with very distinct requirements. Crosshaul areas (those integrating fronthaul and backhaul) are especially critical because of the variability of the demand and the cost of the (own) network deployment, which in many cases is jeopardized by the huge level of investment needed. A common market place to trade the required networking and computing facilities (in the form of a slice) in a multi-domain federated environment is envisaged as the solution for easing the adaptation to future demands. This paper proposes to develop the concept of multi-domain Crosshaul by enabling the dynamic request of Crosshaul slices through a multi-provider exchange.
