Frequently Asked Questions

What types of SD-WAN solutions does China Telecom Americas offer?

China Telecom Americas 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 for China Telecom Americas SD-WAN solutions?

China Telecom Americas SD-WAN solutions cater to diverse use cases, including:

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: China Telecom Americas 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.
