Multi-site SD-WAN architecture with dual data centres (Franklin Street and Mile End) connected via diverse fibre paths and StateNet interconnects for resilience. Court sites connect through SD-WAN edge devices to dual SD-WAN core controllers, with traffic routed through Vocus fibre infrastructure and NBN-based internet access via OCIO firewalls. The design implements network segmentation with DMZ, CORE, DISTRIBUTION, and ACCESS layers, ensuring redundancy across fibre paths and controller failover. Fork this diagram to customize SD-WAN policies, add additional court sites, or adjust firewall rules for your organisation's security posture. This target-state architecture demonstrates enterprise-grade network resilience with geographic diversity and centralised SD-WAN management.
