What is SDA and why is it being deployed?
Published: 26 January 2026
Cisco Software-Defined Access (SDA) is a modern network architecture that provides stronger security, improved visibility and centralised control of the University’s network. It allows IT teams to manage access, security and network configuration more efficiently, helping ensure the network remains secure, scalable and easier to support.
Expected benefits (e.g., improved security, faster connectivity):
SDA delivers a range of long-term benefits, including:
- Simplified network management – faster rollout of changes and easier troubleshooting
- Enhanced security – improved control over who and what can access the network
- Real‑time visibility and analytics – issues can be identified and resolved more quickly
- Greater scalability and flexibility – the network can adapt more easily to future needs
While some of these improvements won’t be immediately visible to end users, they will result in quicker resolution of issues and a more resilient, secure network overall.
Timeline of deployment, including disruption and impact:
Each building or site will have a scheduled change window. Wherever possible, this work will take place over a weekend to reduce disruption. During the change window, users at the affected site will experience periods of network downtime while the new SDA infrastructure is put in place.
