Network softwarisation introduces flexibility in network management by enabling the
deployment of network functions as software modules running on virtual machines …

With the growing adoption of Software Defined Networking (SDN) and Network Function
Virtualization (NFV), large-scale NFV infrastructure deployments are gaining momentum …

Abstract The emergence of Network Function Virtualization enables the deployment of
network services in the form of service function chains. In this context, one of the key …

In the network function virtualization (NFV) environment, network services are usually
provided in the form of service function chains (SFCs), which defines the link order of virtual …

Service function chaining (SFC) is an emerging technique that provides steering of traffic
flows through an ordered set of service functions (SFs). In SFC, high availability is one of the …

The service function chaining paradigm links ordered service functions via network
virtualization, in support of applications with severe network constraints. To provide wide …

A Service Function Chain (SFC) is an ordered Network Function (NF) chain to process flows
or packets for the end-to-end delivery of network services. In the context of Network Function …

Achieving network resiliency in terms of availability, reliability and fault tolerance is a central
concern for network designers and operators to achieve business continuity and increase …

Service function chain (SFC) is widely exploited to provide heterogeneous network services,
which refers to an ordered sequence of network functions that a given flow should traverse …

The network function virtualization (NFV) paradigm replaces hardware‐dependent network
functions by virtual network functions (VNFs) that can be deployed in commodity hardware …
