Flexible support of VNF placement functions in OpenStack

Proceedings of the 2015 1st IEEE Conference on Network Softwarization (NetSoft), 2015
In the context of virtualization and cloud computing, a currently interesting topic is the movement of network functions into the cloud. Since these Virtualized Network Functions have high performance and availability requirements, the placement and resilient deployment of these functions are important issues.

Optimal VNF Placement: Addressing Multiple Min-Cost Solutions

2019
Network Function Virtualization (NFV) can lower the CAPEX and/or OPEX for service providers and allows to deploy services quickly. Randomly placing Network Functions (NF) in the network can cause excessive use of resources such as bandwidth (BW). Consequently, many researchers proposed optimal placement strategies, which place NFs with minimum cost ...

Availability Guaranteed and Resource Efficient VNF Placement in SDN/NFV-Enabled Network through Traffic Forecasting

2025 IEEE International Conference on Web Services (ICWS)
Network Function Virtualization (NFV) enables the realization of dedicated, proprietary network functions as software, which we can instantiate flexibly on commodity servers as Virtual Network Functions (VNFs).

PSVShare: A Priority-based SFC placement with VNF Sharing

2020 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2020
Edge computing resources deployed at the access network are distributed and limited compared to the abundant core cloud resources. With the increasing demand on edge resources by emerging delay-sensitive use-cases, efficient resource utilization is to play an indispensable role.

Towards an efficient VNF placement in network function virtualization

Computer Communications, 2019
Abstract 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 ...
