Virtualizing the Network Services: Network Function Virtualization
2017Network function virtualization (NFV) is rapidly emerging as the de facto approach operators will use to deploy their networks. NFV leverages on cloud computing principles to change the way NFs like gateways and middleboxes are offered. As opposed to today’s tightly coupling between the NF software and dedicated hardware, NFV concept requires the ...

Modular network function virtualization
2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2017Network functions like load balancers and stateful firewalls which traditionally have been packaged in a single proprietary device are now being virtuahzed in software across multiple physical devices networked together to achieve greater flexibility and scale. A virtualization can become very complex.

Virtual Network Function Placement in IoT Network
2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC), 2019This paper investigates an efficient placing mechanism for placing Virtual Network Function (VNF) on the cloud networks to enable the construction of Internet of Things (IoT) service chains with minimal resource usage cost. In particular, we propose a model taking IoT network infrastructure into account.

Adaptive service function selection for Network Function Virtualization networking
Future Generation Computer Systems, 2019Abstract In multiple Service Nodes (SNs) in a Network Function Virtualization (NFV) environment, numerous network functions are carried out. This study concerns the selection of Service Function Instances (SFIs) that are integrated into a Service Function Path (SFP) in resource-constrained networks with various functional requirements.

Predictive Analysis in Network Function Virtualization
Proceedings of the Internet Measurement Conference 2018, 2018Recent 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.

Network Function Virtualization
2018This 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).

vNFC: A Virtual Networking Function Container for SDN-Enabled Virtual Networks
2012 Second Symposium on Network Cloud Computing and Applications, 2012Software-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 ...
