(SPS09: Introducing THE 5G-INFRASTRUCTURE-PPP – Launching the European 5G Initiative - Part IMarket fragmentation has resulted in a multitude of network and cloud/data centre operators each focused on different countries, regions and technologies. This makes it difficult and costly to create infrastructure services spanning multiple countries, such as virtual connectivity or compute resources, as no single operator has a footprint everywhere. The goal of the 5G Exchange (5GEx) project is to enable crossdomain orchestration of services over multiple administrations or over multi-domain single administrations in the context of emerging 5G Networking. This will allow end-to-end network and service elements to mix in multi-vendor, heterogeneous technology and resource environments. 5GEx aims to enable collaboration between operators, regarding 5G infrastructure services, with the view to introducing a unification via NFV/SDN compatible software defined infrastructure multi-domain orchestration for networks, clouds and services.5engAtribución-NoComercial-SinDerivadas 3.0 España5G exchange5GExMulti-domain orchestrationNFV/SDNconference proceedingsTelecomunicacionesopen access15CC/0000027345
