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.

5G Network Slicing as a Service Enabler for the Automotive Sector

Engineering Reports, Volume 7, Issue 1, January 2025.
This paper explores how network slicing can benefit the automotive sector throughout the vehicle lifecycle, from manufacturing to vehicular communications. We analyze the cost equilibrium for network slicing to be effective for car manufacturers, and tests in real 5G networks that demonstrate the performance improvement in OTA updates coexisting with ...

Adaptive placement & chaining of virtual network functions with NFV-PEAR

Journal of Internet Services and Applications, 2019
The design of flexible and efficient mechanisms for proper placement and chaining of virtual network functions (VNFs) is key for the success of Network Function Virtualization (NFV). Most state-of-the-art solutions, however, consider fixed (and immutable)

Autonomous Attack Mitigation Through Firewall Reconfiguration

International Journal of Network Management, Volume 35, Issue 1, January/February 2025.
This graphical abstract shows the workflow of the proposed approach for autonomous attack mitigation through firewall reconfiguration. ABSTRACT Packet filtering firewalls represent a main defense line against cyber attacks that target computer networks daily. However, the traditional manual approaches for their configuration are no longer applicable to

Specifying and Placing Chains of Virtual Network Functions

, 2014
Network appliances perform different functions on network flows and constitute an important part of an operator's network. Normally, a set of chained network functions process network flows.

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.

REMEDIATE: Improving Network and Middlebox Resilience With Virtualisation

International Journal of Network Management, Volume 35, Issue 1, January/February 2025.
ABSTRACT The increasing demand for low‐latency, high‐bandwidth connectivity has introduced novel challenges to delivering strong resilience guarantees in production network environments. Closed hardware platforms, known as middleboxes, that lack visibility and support for state retention remain a key challenge for continuous service delivery during ...
