Multi-objective VNF Placement Optimization with NSGA-III

, 2023
With the rising acceptance of virtual network functions (VNFs) as a replacement for traditional network functions, the optimal placement of VNFs has become a crucial task for ensuring constant performance within constrained resources. This research investigates the challenge of mapping and scheduling VNFs as a multi-objective optimization problem.

VNF and Container Placement: Recent Advances and Future Trends

CoRR, 2022
With the growing demand for openness, scalability, and granularity, mobile network function virtualization (NFV) has emerged as a key enabler for most mobile network operators. NFV decouples network functions from hardware devices. This decoupling allows network services, referred to as Virtualized Network Functions (VNFs), to be hosted on commodity ...

A Knapsack-based Optimization Algorithm for VNF Placement and Chaining Problem

, 2022
International audienceDuring the last decade, we are witnessing the emergence of NFV and SDN to reduce CAPEX and OPEX. Under the SDN paradigm and thanks to NFV, a service can be swiftly deployed by the chaining of several VNFs forming an SFC running on a

Towards Low-latent & Load-balanced VNF Placement with Hierarchical Reinforcement Learning

, 2021
Current orchestration frameworks lack intelligence and handle resources by neglecting service-level and systemwide performance. Towards addressing this gap, we propose a Hierarchical Reinforcement Learning (HRL) design targeting Virtual Network Function (

VNF Placement and Sharing in NFV-based Cellular Networks [PDF]

, 2020
Network Function Virtualization is one of the most relevant enabling technologies for 5G: conceiving a vertical service as a set of virtual functions (a.k.a. VNFs) makes it possible to implement a service at the network edge in a fast and flexible manner,
