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 …

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

This paper proposes an availability-aware service provisioning model with backup sub-
chain-enabled sharing in network function virtualization to minimize the deployment cost. A …

In resource-constrained network function virtualization (NFV) environments, it is expected
that data throughput for service chains is maintained by using virtual network functions …

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

Abstract Network Function Virtualization (NFV) has been proposed as an important
paradigm to speed up the service deployment and provision, by decoupling network …

In the context of Network Function Virtualization (NFV), a Network Service (NS) is defined as
a composition of Network Functions (NFs), which can be Virtual Network Functions (VNFs) …
