A Partition-Aware VNF Placement Methodology for FPGA-Equipped NFVIs

Brazilian Symposium on Computer Networks and Distributed Systems
In the context of Network Function Virtualization (NFV), Field Programmable Gate Arrays (FPGAs) can be used to reduce bottlenecks introduced by the substitution of dedicated hardware middleboxes by virtualized implementations.

Security and High-Availability While Upholding Network Defense Patterns: The Advantages of A2C in O-RAN VNF Placement

ICC 2024 - IEEE International Conference on Communications
Next-generation radio access networks such as the Open Radio Access Network (O-RAN) have alleviated many of the 5G demand and management challenges. However, 0-RAN's intelligence, openness, and virtualization have signifi-cantly increased the attack ...

Optimizing Service Function Chain Mapping in Network Function Virtualization through Simultaneous NF Decomposition and VNF Placement

arXiv.org
Network function virtualization enables network operators to implement new services through a process called service function chain mapping. The concept of Service Function Chain (SFC) is introduced to provide complex services, which is an ordered set of
