A Pattern for a Virtual Network Function (VNF)
Proceedings of the 14th International Conference on Availability, Reliability and Security, 2019Network Function Virtualization (NFV), produces the functions of the network through virtualization of hardware resources. Different networking components such as firewalls, load balancers, and IDS are provided as a service and rely purely on the cloud, which makes expanding and upgrading the network an easy and fast process.

Towards an Efficient VNF Placement in Network Function Virtualization
Computer Communications, 2019Abstract Network Function Virtualization (NFV) decouples network function (also called middlebox function) software from specified appliances onto general shared servers. Thus, it has been being regarded as a promising technology to overcome high Capital Expenditures (CAPEX) and Operational Expenditures (OPEX) on the middlebox deployment and ...

Multi-VNF performance characterization for virtualized network functions
2017 IEEE Conference on Network Softwarization (NetSoft), 2017Network Function Virtualization promises to reduce the overall operational and capital expenses experienced by the network operators. Running multiple network functions on top of a standard x86 server instead of dedicated appliances can increase the utilization of the underlying hardware and reduce the maintenance and management costs.

Journal of Network and Computer Applications, 2019
Abstract The traditional hardware-based physical network functions are increasingly being replaced with software-only Virtual Network Functions (VNFs). A systematic review on the VNF, scoped to cover research papers, open source projects, and standards, is conducted in this work.

VNF management method using VNF Group Table in Network Function Virtualization
2017 19th International Conference on Advanced Communication Technology (ICACT), 2017This paper proposes efficient VNF management method using VNF Group Table in NFV (NFV : Network Function Virtualization), which is gaining attention from many network operator. ETSI ISG NFV WG is researching NFV. It refers to concept of utilizing network function in server OS rather than the equipment. Currently, ETSI ISG WG are divided into six groups,

Guaranteed-Availability Network Function Virtualization With Network Protection and VNF Replication
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017Network function virtualization (NFV) provides an efficient and flexible way to deploy network services in the form of service function chains (SFCs) by adopting generalized equipment. However, software-based virtualized network functions (VNFs) bring new challenge for network operators in providing service availability guarantees. Traditionally, network-

Network Service Chaining Challenges for VNF Outsourcing in Network Function Virtualization
2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015Fundamentally, network function virtualization (NFV) allows virtual network functions (VNFs) to be outsourced by a third party because it separates network functions from their locations. However, the VNF outsourcing raises significant challenges for network service chains, which is a necessary technology to realize NFV. This paper discusses challenges

VNF-DOC: A Dynamic Overload Controller for Virtualized Network Functions in Cloud
2020Network Function Virtualization (NFV) supports enterprises and service providers to build reliable network services in a cost-effective way. Such network services are created by combining one or more Virtual Network Functions (VNFs) hosted in private or public cloud infrastructure.

SummarySoftware‐defined networks (SDN) usually rely on a centralized controller, which has limited availability and scalability by definition. Although a solution is to employ a distributed control plane, the main issue with this approach is how to maintain the consistency among multiple controllers. Consistency should be achieved with as low impact on
