Network Design & SD-WAN

High-performance network architecture for multi-site enterprises — connecting your offices, data centres, and cloud workloads into a single, unified fabric.

Cisco · Meraki · SD-WAN · MPLS · BGP · Fortinet

OVERVIEW

Networks that connect everything. Reliably.

Modern enterprises operate across multiple sites, cloud platforms, and remote workforces. Your network needs to keep up — with the performance, visibility, and resilience to support critical operations without interruption.

Digital Bloc designs and deploys high-availability network architectures from the ground up, including SD-WAN solutions that replace costly legacy MPLS with intelligent, software-defined connectivity.

SD-WAN Specialists

Intelligent traffic routing, failover, and centralised visibility across all your sites.

Multi-site Architecture

Designed for organisations with complex, distributed footprints across Australia and beyond.

Legacy Migration

Seamless transition from MPLS and traditional WAN to modern SD-WAN without disruption.

WHAT’S INCLUDED

Everything you need, nothing you don't.

Network Assessment

Full audit of your existing WAN, LAN, and connectivity infrastructure before design begins.

SD-WAN Design

Custom SD-WAN architecture tailored to your site footprint, traffic patterns, and failover requirements.

LAN & Wi-Fi Design

End-to-end local area network and wireless design for offices, warehouses, and remote sites.

Security Integration

Firewall, ZTNA, and security policy integration built into the network architecture from day one.

Deployment & Cutover

Managed rollout with zero-downtime cutover strategies and on-site support where required.

Monitoring & Management

Centralised network monitoring, alerting, and ongoing management post-deployment.

THE PROCESS

How we deliver.

1

Discovery →

We map your existing network, sites, traffic flows, and pain points to build a clear picture of what needs to change.

2

Design →

We architect your new network — SD-WAN topology, routing policies, security zones, and failover configurations.

3

Deploy →

We roll out the solution site by site, managing cutover carefully to avoid disruption to your operations.

4

Optimise →

Post-deployment we monitor your network 24/7, respond to incidents, and optimise performance over time.

FAQs

Most frequent questions and answers.

MPLS is a dedicated, private network circuit that’s reliable but expensive and inflexible. SD-WAN uses software to intelligently route traffic across multiple connection types — including broadband and 4G/5G — delivering similar reliability at significantly lower cost with far more flexibility.

When planned properly, SD-WAN deployments are minimally disruptive. We use phased rollouts and parallel running strategies to ensure your operations continue uninterrupted throughout the transition.

Yes — we specialise in connectivity solutions for remote and regional sites including 4G/5G failover, satellite integration, and resilient multi-link architectures designed for environments where connectivity options are limited.
