Clear requirements towards the end-to-end orchestration and management plane for 5G networks have been issued by various Industry operators' associations and standard organizations.Over the past couple of years a number of orchestration frameworks have emerged in attempts to realize those requirements.These orchestration frameworks provide coordination and automated management of cloud and networking resources as well as service functions, typically, over a single domain.However, the extension of the orchestration function to coordinate multiple administrative domains has not been directly addressed so far.This paper presents a multi domain functional architecture of the 5G end-to-end management and orchestration plane as an ongoing effort towards its realization within the H2020 ICT14 project 5G Exchange (5GEx).Our architectural proposal follows a bottom up approach based on the analysis of multiple existing resource domains and domain orchestration components.
