Abstract

Network function virtualization(NFV) is being widely recognized as a network paradigm potentially suitable for current and future dynamic network service environment. NFV introduces flexible network function ordering in network service provisioning by proposing separation of network functions from the underlying hardware. Virtualized implementation of network functions as software modules can make network service provisioning simpler by reducing capital expenditure(CAPEX) and operational expenditure(OPEX) among various other advantages. NFV is being discussed with cloud computing framework to provide network functionalities as a cloud service. The placement of virtualized software modules on physical space is a very crucial step in NFV service provisioning. Overall service delivery is greatly affected by the way Virtualized network functions are placed in physical space. In this paper a formal introduction of the placement problem, importance of efficient placement, challenges faced in placement and study of various solution approaches is presented.
