NFV-Throttle: An Overload Control Framework for Network Function Virtualization
IEEE Transactions on Network and Service Management, 2017Network function virtualization (NFV) aims to provide high-performance network services through cloud computing and virtualization technologies. However, network overloads represent a major challenge. While elastic cloud computing can partially address overloads by scaling on-demand, this mechanism is not quick enough to meet the strict high ...

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.

Optimized Virtual Network Functions Migration for NFV
2016 IEEE 22nd International Conference on Parallel and Distributed Systems (ICPADS), 2016Combining with software-defined networking and IT virtualization technologies, Network Function Virtualization (NFV) has been proposed as an important technology to speed up deployment of new network services. VNF (Virtual Network Function) migration is a critical step to redeploy virtual network functions for providing better network services ...

Energy-efficient virtual security function placement in NFV-enabled networks
Sustainable Computing: Informatics and Systems, 2021Abstract In network functions virtualization (NFV) environments, network security is provided with the deployment of virtual security functions (VSF) on general-purpose servers to filter and monitor the incoming traffic. However, the traffic handled by VSFs may have different security requirements in a network.

On efficient virtual network function chaining in NFV-based telecommunications networks
Cluster Computing, 2018Network function virtualization enables the softwarization of network functions on standardized commodity hardware, which is promising to help the network carriers to achieve a lower investment cost, a shorter time to deployment, as well as a more flexible and dynamic way of network configuration and management.

NFV-VITAL: A framework for characterizing the performance of virtual network functions
2015 IEEE Conference on Network Function Virtualization and Software Defined Network (NFV-SDN), 2015Network Function Virtualization (NFV) brings a cloud service automation paradigm to demand-driven elastic flexing of infrastructure resources. Thus, it is essential to characterize the impact of hardware and virtualization options on the virtual network function (VNF) performance, and on the load on underlying infrastructure.

NFVGuard: Verifying the Security of Multilevel Network Functions Virtualization (NFV) Stack
2020 IEEE International Conference on Cloud Computing Technology and Science (CloudCom), 2020Network Functions Virtualization (NFV) enables agile and cost-effective deployment of multi-tenant network services on top of a cloud infrastructure. However, the multi-tenant and multilevel nature of NFV may lead to novel security challenges, such as stealthy attacks exploiting potential inconsistencies between different levels of the NFV stacks ...

NFV-Inspector: A Systematic Approach to Profile and Analyze Virtual Network Functions
2018 IEEE 7th International Conference on Cloud Networking (CloudNet), 2018Network Function Virtualization (NFV) focuses on decoupling network functions from proprietary hardware (i.e., middleboxes) by leveraging virtualization technology. Combining it with Software Defined Networking (SDN) enables us to chain network services much easier and faster.

MD2-NFV: The case for multi-domain distributed network functions virtualization
2015 International Conference and Workshops on Networked Systems (NetSys), 2015Motivated by the vision of Network Functions Virtualisation (NFV) spanning different administrative domains, this position paper makes the case for multi-domain, distributed NFV (MD2-NFV). To this end, we present MD2-NFV as a natural evolution of the NFV paradigm to deliver a distributed deployment of Virtualized Network Functions (VNFs) as a service ...
