Virtual Network Function Placement with Function Decomposition for Virtual Network Slice
2018 IEEE Conference on Standards for Communications and Networking (CSCN), 2018Virtual network functions (VNFs) are placed across the network to complete the required network performance of virtual network slice (vNS), and the placement of VNFs is flexible and problematic. Besides, a VNF can be decomposed into multiple sub-functions, and the same type of sub-function can be re-used by multiple VNFs.

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 ...

Network Functions Virtualization (NFV)
2021Network functions virtualization (NFV) is consolidating as one of the base technologies for the design, deployment, and operation of network services. NFV can be seen as a natural evolution of the trend to cloud technologies in IT, and hence perceived as bringing them to the network provider environments.

Orchestrating Virtualized Network Functions
IEEE Transactions on Network and Service Management, 2016Middleboxes or network appliances like firewalls, proxies, and WAN optimizers have become an integral part of today’s ISP and enterprise networks. Middlebox functionalities are usually deployed on expensive and proprietary hardware that require trained personnel for deployment and maintenance. Middleboxes contribute significantly to a network’s capital

Accelerating network function virtualization
2021Network function virtualization (NFV) [50] is increasingly used to implement network operations traditionally implemented in customized ASICs. NFV employs commodity, general-purpose computer hardware located in a datacenter. General-purpose computing hardware has performance limitations limiting the scope of NFV.

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.

User mobility-aware Virtual Network Function placement for Virtual 5G Network Infrastructure
2015 IEEE International Conference on Communications (ICC), 2015Cloud offerings represent a promising solution for mobile network operators to cope with the surging mobile traffic. The concept of carrier cloud has therefore emerged as an important topic of inquiry. For a successful carrier cloud, algorithms for optimal placement of Virtual Network Functions (VNFs) on federated cloud are of crucial importance.

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).
