Resilient deployment of virtual network functions

2013 5th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT), 2013
Moving services to the cloud is a trend that has been going on for years now, with a constant increase in sophistication and complexity of such services. Today, even critical infrastructure operators are considering moving their services and data to the cloud; most prominently are telecommunication operators, who are calling for running their service ...

Network Functions Virtualization

2015
Network Functions Virtualization (NFV) has emerged as a new paradigm for designing, deploying and operating network services. It is a natural evolution of the current trend of applying cloud technologies to Information Technology (IT) services, bringing them to network provider environments.

Predictive Analysis in Network Function Virtualization

Proceedings of the Internet Measurement Conference 2018, 2018
Recent deployments of Network Function Virtualization (NFV) architectures have gained tremendous traction. While virtualization introduces benefits such as lower costs and easier deployment of network functions, it adds additional layers that reduce transparency into faults at lower layers.

Automated virtual network functions onboarding

2016 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2016
Network functions virtualization (NFV) opens up a new ability of network enablement through agile network DevOps to design, develop, and test new services and to provide ongoing updates of existing services. This paper proposes a tool and methodology to aid the NFV designer to rapidly design and onboard new services and applications.

The virtual network function placement problem

2015 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2015
Network functions are widely deployed in modern networks, providing various network services ranging from intrusion detection to HTTP caching, for the purpose of performance, security or policy compliance. According to a recent survey [6], network function deployments are ubiquitous: on par with the number of L3 infrastructures.

Placement Issues in Network Function Virtualization

2020
Network function virtualization(NFV) is being widely recognized as a network paradigm potentially suitable for current and future dynamic network service environment. NFV introduces flexible network function ordering in network service provisioning by proposing separation of network functions from the underlying hardware.

vNFC: A Virtual Networking Function Container for SDN-Enabled Virtual Networks

2012 Second Symposium on Network Cloud Computing and Applications, 2012
Software-defined networks (SDN) has gradually been deployed on commercial networks such as datacenter networks. Current SDN is based on OpenFlow technology that is a set ofnetwork flow control API for switch devices. For instance, network reachability between end-hosts (or virtual machines), packet filtering mechanisms, and status management of ...

Network Function Virtualization

2018
This chapter covers Network Function Virtualization (NFV); previously you were introduced to high-level virtualization concepts in the “Software Defined Networking (SDN)” chapter. NFV and SDN are complementary technologies used in conjunction for achieving lower operating expense (OpEX) and capital expense (CapEX).
