The University of Dundee underwent a campus network refresh and IT restructuring project. The goals were to replace aging network infrastructure, improve wireless access and performance, reduce complexity, and improve security. A tender process was used to select a new vendor. The selected solution involved switching, software-defined networking, firewalls, and wireless access points to provide a modernized network across campus. The project has been progressing on time according to updates published online and through social media.

- 15. Click to edit Master title style Transforming lives www.dundee.ac.uk Goals and Objectives - Technical • Replace the campus (Border routers, core switching, edge access layer in all locations including wireless), wireless and datacentre networks with consistent reliable hardware • Improve the student experience through the enhanced consistency and availability of wireless infrastructure, covering both internal and external spaces • Reduce the complexity in the network through revising the topology of the Campus, Wireless and Datacentre environments • Improve the performance of the desktop and mobile applications through use of faster connections • Improve the security posture of the University to mitigate the risk from unauthorised or incompliant devices being connected to the network • Remove single points of failure by having vendor standard configuration that can be supported by vendor remotely or onsite
- 16. Click to edit Master title style Transforming lives www.dundee.ac.uk Goals and Objectives - Commercial • Remove the requirement to invest significant amounts in capital refreshes every 5-6 years by changing to a monthly operational cost • Remove the variation in costs of growth of network • Operationalise the network to clearly define standard changes so they can be carried out by non-specialist staff following the strategic direction of the IT restructuring • Enter into a co-sourcing arrangement with the suppliers for the ongoing management of the network to reduce the service and design risks

Increase the coverage of wireless across Campus Reduce calls logged regarding wireless access Reduce the number of switches replaced each month Equivalence between wired and wireless network in terms of capabilities
