Network function virtualization enables service providers to flexibly deploy network services.
The existing works mainly focus on function placement and capacity allocation without …

This paper investigates a service deployment model for network function virtualization which
handles per-flow priority to minimize the deployment cost. Service providers need to …

Network function virtualization enables to deploy network services more flexibly with virtual
network functions (VNFs). A service provider needs to allocate the required VNFs to hosts …

Network function virtualization is a promising ar-chitecture for replacing dedicated hardware
middle boxes with adaptable software, commonly called virtual network functions. A service …

Recently, network function virtualization (NFV) has been proposed to solve the dilemma
faced by traditional networks and to improve network performance through hardware and …

Network operators can operate services in a flexible way with virtual network functions
thanks to the network function virtualization technology. Flow partition allows aggregated …

Service chaining provides network services by flexibly configuring service chains that
connect virtualized network functions (VNFs) in the appropriate order so as to satisfy users' …

To accelerate the implementation of network functions/middle boxes and reduce the
deployment cost, recently the concept of Network Function Virtualization (NFV) has emerged …

This paper proposes a service deployment model for network function virtualization to
minimize the deployment cost with capacity sharing and priority queuing. A service provider …

Network function virtualization (NFV) and Service function chaining (SFC) can fulfill the
traditional network functions by simply running special softwares on general‐purpose …
