… These virtual networks need to be configured and have their life … virtual networks need to
be allocated in a dynamic manner on physical machines by using efficient resource allocation …

… In this paper, we focus on minimizing the total number of Virtual Network Function (VNF)
instances to provide a specific service (possibly at different locations) to all the flows in a network…

… the advent of Network Function Virtualization (NFV), network services that … Virtual Network
Functions (VNFs) that are hosted on general-purpose commodity hardware. This new network …

… We consider a set of network functions denoted by Φ. Each flow needs to be processed by
… network functions. We assume that flows can get processed by all required network functions …

… network functions from hardware. A network function is virtualized as a virtual network
function (VNF) running on a node in the network; each node is equipped with virtual machines (…

… In NFV, the requested service is implemented by a sequence of Virtual Network Functions
(VNF) that can run on generic servers by leveraging the virtualization technology. These VNFs …

… of physical substrate network resources, aiming to logically separate the set of virtual
network functions (VNFs) within the physical infrastructure. For example, one network slice is …
