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.

Accommodating Dynamic Traffic Immediately: A VNF Placement Approach

ICC 2019 - 2019 IEEE International Conference on Communications (ICC), 2019
Network function virtualization has become a promising technology recently. To accommodate dynamic traffic such as burst, NFV can scale virtual network functions (VNFs) across several physical servers, which is known as horizontal scaling, or enlarge the capacity of a VNF leveraging idle resources in one physical server, which is called vertical ...

Multi-Resource Orchestration and Energy-Aware VNF Placement for Open RAN

IEEE Conference on Network Softwarization
This paper summarizes the PhD research work conducted on resource orchestration in disaggregated Open RAN (O-RAN) architectures. In O-RAN, the gNB radio protocol stack is split into virtualized functions- Centralized Unit (CU), Distributed Unit (DU), and

O-RAN-Oriented Approach for Dynamic VNF Placement Focused on Interference Mitigation

ICC 2024 - IEEE International Conference on Communications
Interference mitigation is a common benefit claimed by disaggregated and virtualized radio access networks (vRAN). However, this benefit depends on centralizing the proper virtual network functions (VNFs) from the protocol stack of neighbor radio units ...

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

Joint Dynamic VNF Placement and Delay and Jitter Aware Multicast Routing in NFV-Enabled SDNs

IEEE Transactions on Mobile Computing
For reliability, security and scalability, Multicast Request flows (MRs) need to traverse a Service Function Chain (SFC) that consists of series of Virtual Network Functions (VNFs) such as firewalls, encoder-decoder in Network Function Virtualization ...
