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 resource allocation.

5G 网络中市场驱动的多域网络服务编排

新型增强型多媒体服务的出现使网络运营商必须支持创新服务，同时确保端到端服务质量要求和盈利能力。最近，网络功能虚拟化 (NFV) 被吹捧为 5G 网络中一种经济高效的底层技术，可有效提供新服务。这些基于 NFV 的服务越来越多地与多域网络相关联。然而，与跨域交互相关并由底层技术和管理权限的异质性所强调的几个编排问题提出了一个重要挑战。在本文中，我们通过提出一种智能且有利可图的基于拍卖的方法来解决跨域交互问题，以允许域间资源分配。
