Frequently Asked Questions

What types of SD-WAN solutions are you offering?

CTA offers self-managed solutions through various leading SD-WAN brands. We manage the underlay network and have developed integrations to offer hybrid SD-WAN branch and MPLS core architectures. This increases network management agility inside China and also improves cross border China WAN links.

What are the most popular use cases?

Hybrid WAN: Most enterprises choose a hybrid WAN model. This allows them to easily connect branch offices and mobile users. The most available and best path is steered through an MPLS / IP VPN network or authorized IPSec tunnels. These tunnels can be set up with Versa, Viptela, or Silver-Peak SD-WAN technologies.

Dynamic DIY or Managed SD-Branch: Operators can choose dynamic DIY or managed SD-Branch. If they opt for dynamic DIY, they must provision and manage business policies and devices themselves. If they elect managed SD-Branch, we will handle installation and ongoing support.

Seamless Direct-to-Cloud Connections: Transform traditional hub-and-spoke architectures to a secure, direct-to-cloud WAN architecture. This avoids the delay and added costs of backhauling traffic over MPLS to a firewall in the data center.

Intelligent Internet Acceleration: CTA’s affiliate SDN network fabric enables customers to adjust remote sites and optimize traffic flows across their WAN.

Remote Access: Fast Access Soft Terminal (FAST) is a one-of-a kind enterprise-grade remote access tool with high security, stability, and flexibility globally.

What is the solution design/architecture?

We recognized that network programmability and automation would simplify multi-cloud connectivity. To achieve this, we built a global backbone spanning 26 sites. This backbone is cloud-connected and SD-WAN enabled, providing superior Quality of Experience (QoE) and centralized control. It works with any underlying transport technology or application architecture.
