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.

On orchestrating virtual network functions
2015 11th International Conference on Network and Service Management (CNSM), 2015Middleboxes 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

Placement of virtual network functions for network services
International Journal of Network Management, 2023SummaryNetwork function virtualization (NFV) is a name of technology for replacing hardware‐based network functions with software programs. Virtual network function (VNF) is a software program that replaces the hardware‐based network functionality. The replacement of the hardware‐based network functions (middleboxes) with software programs promises 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.

Algorithms for functionalities of virtual network: a survey
The Journal of Supercomputing, 2021Nowadays, network functionalities are provided through dedicated hardware middleboxes. These hardware middleboxes are statically embedded with network topology to provide the network services. The types of middleboxes increase in the network, with an increased number of users and network services.

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 ...

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.
