Impact of VNF placements on QoE monitoring in the cloud

International Journal of Network Management, 2018
Summary The fast growth of video streaming is responsible for a huge amount of traffic over the past few years. Because of the variety of video content on the Internet, a potential market is emerging for video providers. However, a rapid increase in video traffic and users poses challenges for network operators maintaining user ...

Strategies for VNF Placements in Large Provider Networks

Optical Fiber Communication Conference, 2017
We examine three strategies of VNF placement in a provider network: static service chains; seamless VNF duplication and VNF-dynamic-splitting. A constrained optimization applied to a large provider evaluates these strategies and showcases cost-latency trade-off.

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.

IllumiCore: Optimization Modeling and Implementation for Efficient VNF Placement

2021 International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2021
Network Function Virtualization (NFV) enables telecommunication operators to place and allocate resources dynamically to address the needs of Internet of Things (IoT), Intelligent Edge Computing (IEC) and emerging 5G services in a highly efficient manner. The efficient Virtual Network Function (VNF) placement and deployment largely depend on optimizing

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.

Distributed Approach to Adaptive VNF Manager Placement Problem

2019 20th Asia-Pacific Network Operations and Management Symposium (APNOMS), 2019
Network function virtualization (NFV) has been a promising approach to flexible and scalable deployment of network services. In NFV management and orchestration (NFV-MANO) architectural framework, VNF managers (VNFMs) should be deployed to manage the lifecycle of virtualized network functions (VNFs). VNFM placement problem (MPP) is to deploy VNFMs that

On Demonstrating the Gain of SFC Placement with VNF Sharing at the Edge

2019 IEEE Global Communications Conference (GLOBECOM), 2019
The demand for edge resources is increasing and will continue to rise especially because of delay- sensitive applications. Because of the limited resources at the network edge, efficient resource utilization will play a crucial role. In this paper, we demonstrate the gain of VNFs sharing- based service function chaining (SFC) requests placement, as a ...
