VNF-AAP: Accelerator-aware Virtual Network Function Placement [PDF]

2019 IEEE Conference on Network Function Virtualization and Software Defined Networks (NFV-SDN), 2019
Network Function Virtualization aims to migrate packet-processing tasks from special-purpose appliances to Virtual Network Functions (VNFs) running on x86 or ARM servers. However, achieving the line-rate packet-processing for VNFs running on CPUs can be a challenging task.

Protection Strategies for Dynamic VNF Placement and Service Chaining [PDF]

2021 International Conference on Computer Communications and Networks (ICCCN), 2021
Network Function Virtualization (NFV) provides a major shift in the provisioning of telecommunication services by decoupling network functions from dedicated hardware devices. Such decoupling enables operational expenditure (OpEx) and capital expenditure (CapEx) reduction and allows to increase service agility.

Dynamic, Latency-Optimal vNF Placement at the Network Edge [PDF]

IEEE INFOCOM 2018 - IEEE Conference on Computer Communications, 2018
Future networks are expected to support low-latency, context-aware and user-specific services in a highly flexible and efficient manner. One approach to support emerging use cases such as, e.g., virtual reality and in-network image processing is to introduce virtualized network functions (vNF)s at the edge of the network, placed in close proximity to ...

Genetic Algorithm for Holistic VNF-Mapping and Virtual Topology Design [PDF]

IEEE Access, 2020
Next generation of Internet of Things (IoT) services imposes stringent requirements to the future networks that current ones cannot fulfill. 5G is a technology born to give response to those requirements. However, the deployment of 5G is also accompanied

Sustainable placement of VNF chains in Intent-based Networking

Proceedings of the IEEE/ACM 16th International Conference on Utility and Cloud Computing, 2023
Intent-based networking (IBN) aims at automatically driving network configurations and operations to fulfil high-level intents specified by infrastructure providers and application operators. Deploying Virtual Network Function (VNF) chains onto the available network resources is a way to model and fulfil intents.

Efficient VNF placement for service function chaining

, 2021
By deploying the network functions (NFs) as software applications called Virtual Network Functions (VNF), Network Function Virtualization (NFV) helps the Service Provider (SP) to reduce the Capital Expenditure (CAPEX), Operation Expense (OPEX) and save a lot of deployment time. However, there are still many challenges that remain to be solved in NFV (e.

Routing-Led Placement of VNFs in Arbitrary Networks [PDF]

2020 IEEE Congress on Evolutionary Computation (CEC), 2020
The ever increasing demand for computing resources has led to the creation of hyperscale datacentres with tens of thousands of servers. As demand continues to rise, new technologies must be incorporated to ensure high quality services can be provided without the damaging environmental impact of high energy consumption. Virtualisation technology such as
