Sharing of crosshaul networks via a multi-domain exchange environment for 5G services

Next 5G networks will force service and network providers to support a huge variety of final services with very different requirements in terms of bandwidth, latency, etc. In parallel, vertical industries, as customers, will use 5G networks as technical enablers to support their businesses, demanding appropriate mechanisms for a flexible access and control of network and computing resource slices in the locations where such vertical have business. Since the footprint and the availability of resources to support the variety of services could be limited on the primary provider side, open environments enabling the trading of resources in the form of slices are required to facilitate the sharing of infrastructure with the necessary isolation and scalability. Here, this is exemplified by the proposal of adaptations between two prevalent architectures being defined in the EU H2020 projects 5G-Crosshaul and 5GExchange for allowing the trading of crosshaul resources enabling 5G services for Verticals.
