Software defined networking (SDN) and network function virtualization (NFV) are key
enablers for service-level customized network slicing in fifth generation (5G) core networks …

Modern services consist of interconnected components, eg, microservices in a service mesh
or machine learning functions in a pipeline. These services can scale and run across …

Network function virtualization (NFV) is a promising paradigm for network service
provisioning which decouples the network functions from the physical infrastructure …

Networks can now process data as well as transporting it; it follows that they can support
multiple services, each requiring different key performance indicators (KPIs). Because of the …

The adoption of virtualization technologies in networking is promoting a radical innovation in
the way network services are managed and delivered. Indeed, some network services may …

Abstract Network Function Virtualization (NFV) opens us great opportunities for network
processing with higher resource efficiency and flexibility. In this respect, there is an …

Network function virtualization is a promising technology for providing personalized services
via agile service function chains (SFCs). Flexible SFC orchestration and rational resource …

This paper proposes a set of algorithms to extend initially deployed Virtualized Network
Functions Forwarding Graphs (VNF-FG or Service Function Chains-SFCs) previously …

Although network function virtualization (NFV) has been proven to be beneficial in terms of
equipment cost, service delivery flexibility, and time-to-market, most of the studies in this …

Current service function chaining (SFC) solutions are cumbersome adaptations of classic
routing mechanisms, which lack flexibility and agility to cope with new dynamic services …
