About This Architecture

Enterprise SD-WAN mesh architecture connecting two primary data centres (Hawthorn and Edinburgh) with 300 SIP channels, application-aware routing, and failover policies across hybrid access technologies. Traffic flows from cloud/SaaS through SD-WAN overlay to core data centres, then branches to enterprise sites via dedicated IP-Line fibre (100–250 Mbps), remote sites via Vocus RBBP/R1 (50–100 Mbps), and standard branch sites via NBN TC4 broadband (50–250 Mbps). This architecture optimises cost and performance by matching access tier to site capability—avoiding over-provisioning where fibre or high-speed access cannot deliver benefit. Fork this diagram to customise site bandwidth, add regional hubs, or adjust SIP channel allocation for your multi-site enterprise network.

How do I design an enterprise SD-WAN network that optimises bandwidth across distributed sites with different access technologies?

This diagram shows a hybrid SD-WAN mesh connecting two primary data centres with site-by-site access selection: dedicated IP-Line fibre for high-performance sites (100–250 Mbps), Vocus Enterprise Internet for remote/rural sites (50–100 Mbps), and NBN TC4 broadband for standard branches (50–250 Mbps). The SD-WAN overlay provides application-aware routing and failover, while centralised SIP (300 cha
