Optimal Service Function Chain Composition in Network Functions Virtualization [PDF]
, 2017 AbstractNetwork Functions Virtualization (NFV) is an emerging initiative where virtualization is used to consolidate Network Functions (NFs) onto high volume servers (HVS), switches, and storage. In addition, NFV provides flexibility as Virtual Network Functions (VNFs) can be moved to different locations in the network.
