Research overview
To design a system architecture for a distributed software-defined mixed wired/wireless network, which integrates time-sensitive applications. Show that such applications can be deployed flexibly but reliably in a multi-domain wireless software-defined network, and that such a network can support traffic with a high granularity of different security requirements.

To design a system architecture for a distributed software-defined mixed wired/wireless network, which integrates time-sensitive applications. Show that such applications can be deployed flexibly but reliably in a multi-domain wireless software-defined network, and that such a network can support traffic with a high granularity of different security requirements.
Using standardised fully programmable wireless network elements switches, Defence can retain complete control and flexibility over the behaviour of any dynamic heterogeneous network.
We understand how to design a system architecture for a distributed software-defined network, which includes the potential for bridging across multiple heterogeneous bearers and integrates Time-Sensitive Networking (TSN)-based applications by means of a systematic framework of Application Programming Interfaces.
Building the PoC is work in progress, and can only contain a few example service, e.g. TSN and trust-based routing (“trust 5G more than Wifi links”)
With P4 programmable switches on the southbound of SDN controllers and any already existing programmable API on the northbound interface, Defence can retain complete control and flexibility over the behaviour of any dynamic heterogeneous network.
The possibilities are absolutely boundless and include the gathering of large amounts of very low-level network data for the sake of training AI models that can aid in day-to-day understanding of how the network behaves and decision making on how it should behave.
In our project we focus on:
- Extension of traditional Software-Defined Network with novel controllers for wireless networks
- Have multiple controllers collaborating
- Include multiple bearers
- Include Time-Sensitive Networking
- Achieve intelligent routing based on security and timing requirements
