The advent of a new breed of enhanced multimedia services has put network
operators into a position where they must support innovative services while
ensuring both end-to-end Quality of Service requirements and profitability.
Recently, Network Function Virtualization (NFV) has been touted as a
cost-effective underlying technology in 5G networks to efficiently provision
novel services. These NFV-based services have been increasingly associated with
multi-domain networks. However, several orchestration issues, linked to
cross-domain interactions and emphasized by the heterogeneity of underlying
technologies and administrative authorities, present an important challenge. In
this paper, we tackle the cross-domain interaction issue by proposing an
intelligent and profitable auction-based approach to allow inter-domains
