Description
Resource orchestration has a major impact on improving the performance of network services and reducing the system cost composed of both capital expenditures and operational expenses in network functions virtualization (NFV). In this paper, we consider the optimal resource orchestration problem in a multi-domain NFV system under the competition among multiple NFV service providers (NSPs). In particular, we analyze a game on an NFV platform where an NSP can reserve different types of resources, including the virtual computing, storage, and network resources, and the non-virtualized resources allocated by various NFV domains, for optimizing the utility in an individual manner. We also derive a necessary and sufficient condition for equilibrium under the competition among NSPs. We further investigate the equilibrium in a scenario of cooperation where NSPs build their own NFV infrastructure and join …
