OMNI: OpenFlow MaNagement Infrastructure [PDF]

2011 International Conference on the Network of the Future, 2011
Managing computer networks is challenging because of the numerous monitoring variables and the difficulty to autonomously configure network parameters. This paper presents the OpenFlow MaNagement Infrastructure (OMNI), which helps the administrator to control and manage OpenFlow networks by providing remote management based on a web interface.

Energy‐Aware Controller Placement With Delay Guarantees for In‐Band SDN

International Journal of Network Management, Volume 36, Issue 1, January/February 2026.
ABSTRACT Software‐defined networking (SDN) enables flexible, programmable networks, but in large deployments, poor controller placement can raise latency and energy use. This paper presents a practical in‐band SDN model and an optimization method that jointly accounts for control‐plane delay and device power consumption to place controllers and ...

Centralised Key Management System Architecture for Topology‐Aware and Quantum‐Resilient Security in QKD‐Integrated SDN Control Planes

IET Quantum Communication, Volume 7, Issue 1, January/December 2026.
This paper was not transferred from another journal. ABSTRACT Software‐defined networking (SDN) consolidates network control at a centralised controller, making the southbound TLS‐protected channel between the controller and OpenFlow switches the principal security boundary of the entire network.

Providing of QoS-Enabled Flows in SDN (Exemplified by VoIP Traffic)

Proceedings of the International Conference on Applied Innovations in IT, 2017
This paper provides a proof of concept of an SDN Application to provide QoS for real-time services on SDN networks. Common real-time services are for example VoIP or M2M protocols like OPC UA and MQTT.

A Proposed Method for TCAM Optimization in SDN

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
OpenFlow, a key data plane protocol in software‐defined networking (SDN), relies heavily on ternary content addressable memory (TCAM) to achieve high‐speed packet matching. However, as OpenFlow evolves to support a broader set of match fields, the demand for TCAM storage grows significantly due to its support for arbitrary wildcards.

P4‐QUPF: A P4‐Based QoS Framework for 5G‐UPF

International Journal of Network Management, Volume 35, Issue 6, November/December 2025.
ABSTRACT The demands of today's 5G mobile network, especially low latency and high bandwidth, are a big challenge for the 5G Core (5GC) provider. The most critical user data packet handler in the 5GC network function (NF) is the user plane function (UPF), which is responsible for moving data from the user equipment to the destination data network, and ...

Limitations of openflow topology discovery protocol [PDF]

2017 16th Annual Mediterranean Ad Hoc Networking Workshop (Med-Hoc-Net), 2017
OpenFlow Discovery Protocol (OFDP) is the de-facto protocol used by OpenFlow controllers to discover the underlying topology. In this paper, we show that OFDP has some serious security, efficiency and functionality limitations that make it non suitable for production deployments.
