How our SD-WAN architecture works

POP nodes are built on grade-A data centers and public cloud regions. A central controller monitors every node and link, selecting paths by real-time quality; nodes interconnect over high-speed backbones.

SD-WAN architecture: HQ, branches and cloud interconnected via POP nodes
Access layer aggregates multiple links; the POP layer performs routing and acceleration; cloud and data center workloads are orchestrated centrally.

Why enterprises choose us

No generic product stacks: we look at your current network first, then decide which links and redundancy levels the design needs.

Two-city nodes: Shenzhen + Hong Kong

Connect in either city. Cross-border traffic stays on our own paths instead of detouring through third parties; the Hong Kong node also aggregates international breakout and overseas branches.

Twenty years of delivery

Serving enterprise customers since 2005: multi-branch networking and colocation projects across manufacturing, finance, retail and education.

Predictable cost

At equal bandwidth, hybrid SD-WAN designs typically save around 30% versus pure leased-line plans. Scale on demand, billed monthly.

Fast delivery, audited operations

Standard projects go live in 3-10 working days; core services target 99.99% availability with 7x24 monitoring and incident response.

Frequently asked questions

Colocation vs. dedicated server rental - which should I choose?

Colocation places your own servers in our racks; we provide power, cooling, bandwidth and security. Rental uses servers we provide, billed monthly with no hardware purchase. Choose colocation when you already own hardware or need specific configurations; choose rental for fast, asset-light launches. Both support per-U or full-rack billing.

How long does SD-WAN deployment take?

With circuits ready, standard projects complete equipment delivery, configuration and testing within 3-10 working days. International or cross-border leased lines add carrier provisioning cycles, typically 2-4 weeks. Exact schedules follow the site survey and carrier confirmation.

What SLA do you provide?

Carrier-grade SLAs: up to 99.99% availability for core network services with defined response and restoration times. Important projects can add dual-link/dual-device redundancy, 7x24 monitoring and a dedicated technical manager.

HQ in Shenzhen with branches in Hong Kong or overseas - one network?

Yes. SD-WAN layered with enterprise lines, cloud interconnects and internet links brings your Shenzhen HQ, the Hong Kong node and overseas branches into one controlled network with unified policies, central operations and application-aware routing.

What does the private cloud solution include?

Assessment and capacity planning, compute/storage pool design, network and security policy, deployment, data migration and ongoing operations - deployable in your own room, our hosted data center or a hybrid model.
