VNFs reconfiguration in 5G networks
2022 12th International Workshop on Resilient Networks Design and Modeling (RNDM), 2022 We consider a problem of allocating Virtual Network Functions (VNFs) in 5G networks, treating it as a multiple multidimensional knapsacks reconfiguration problem where items represent VNFs and knapsacks represent servers on which VNFs are able to run.

Design and Implementation of Network-Aware VNF Migration Mechanism
IEEE Access, 2020 By separating network functionalities from the dedicated hardware and implementing them in the form of Virtual Network Function (VNF), Network Function Virtualization (NFV) provides a new service paradigm called Service Function Chain (SFC).

Particle-in-cell simulations of electron acceleration by a simple capacitative antenna in collisionless plasma [PDF]
, 2004 We examine the electron acceleration by a localized electrostatic potential oscillating at high frequencies by means of particle‐in‐cell (PIC) simulations, in which we apply oscillating electric fields to two neighboring simulation cells.

B-VNF: Blockchain-enhanced Architecture for VNF Orchestration in MEC-5G Networks [PDF]
2020 IEEE 3rd 5G World Forum (5GWF), 2020 The roll-out of 5G technology will nurture the realization of broadband, ultra-reliable, and zero latency services. Network Function Virtualization (NFV) and Multi-Access Edge Computing (MEC) are among the key enablers for 5G. The synergy between NFV and MEC allows migration of Virtual Network Functions (VNF) from cloud to the edge of the network ...

Comparison of Different Protection Schemes in the Design of VNF-Mapping with VNF Resiliency
2020 22nd International Conference on Transparent Optical Networks (ICTON), 2020 Producción Científica Network Function Virtualization (NFV) is a promising networking paradigm that will ease the network manageability and increase its flexibility, while reducing costs. In this paradigm, operators must solve the Virtual Network Function (VNF) placement and chaining problems.
