EN2ESO 2016, End-to-end service orchestration for 5G and beyond Workshop, in cooperation with IUCC 2016, 15th International Conference on Ubiquitous Computing and Communications, December 14-16, 2016, Granada, Spain

In this paper we focus on the problem of multidomain orchestration for Network Function Virtualization (NFV), over multi-technology environments. In order to facilitate
service deployment in end-to-end setups, new orchestration designs are required that exploit and advance existing methodologies. We examine in detail the challenges on multi-domain NFV orchestration for the general case and we provide the current landscape and existing technologies. We also describe a reference architecture for the problem of multi-domain NFV orchestration, that also supports the concept of Network Slicing. Finally, we present a realization of the architecture proposed for the LTE network and we describe a use case with LTE-specific considerations.
