SD-WAN | Chunghwa Telecom Global

Introduction Chunghwa Telecom's SD-WAN service platform is built on 60 nodes and 8 foreign IDCs, connecting MPLS IPVPN networks, TWGate Managed Internet services, Chunghwa Telecom satellite services, stable regional partners, and mobile network. This setup allows Chunghwa Telecom to provide customers with local, one-stop service platforms in China, Asia, Southeast Asia, Europe, and the Americas.

Feature

Heterogenous Network Integration SD-WAN integrates MPLS IPVPN, Internet, and mobile network to provide a stable and flexible network infrastructure.

Diversity of Distribution Mechanisms The solution supports various distribution mechanisms, including application layer, port, and IP, offering flexibility in configuring active-active or active-standby setups for enhanced redundancy.

Centralized Cloud Management A unified cloud management platform allows for streamlined network configuration through a user-friendly web interface, eliminating the need for individual device setting.

Real-time Network Visibility and Analytics Gain insights into network performance with real-time network quality analysis, traffic analysis, and bandwidth usage reports, enabling proactive network management.

Scenario 1：Simplified management and settings

Network Environment:

Headquatered in Taiwan.
5 overseas locations, including 3 in Asia-Pacific, 2 in America and Europe respectively.
All bases have MPLS IPVPN and broad-band Internet
Headquarter: MPLS IPVPN 30Mbps / Internet 100Mbps
Asia-Pacific locations: MPLS IPVPN 10Mbps / Internet 50Mbps
U.S. and European bases: MPLS IPVPN 5M / Internet 20Mbps

Solutions:

Using SD-WAN to supply web-based graphic settings make it more convenient for the customer to manage and complete settings over a single graphical interface.
When SD-WAN is used to bring several management units together for the most important SD-WAN command center, it requires ensuring the accessibility of the network and equipment. Chunghwa Telecom set up its SD-WAN and its management units on its backbone network, meaning that the customer need not worry about set up.
With Chunghwa Telecom's SD-WAN network management services, it can better understand the customer's network environment and use needs, meaning it can help the client to plan, make settings, and manage their network.
Chunghwa Telecom provides a complete management system.
The professional maintenance personnel of the 24-7 managed service center provide services in both Chinese and English.

Scenario 2：Application distribution and enhanced service quality

Network Environment:

The customer's headquarters is in Taiwan. There are 2 bases overseas, each having Internet and MPLS IPVPN services, with a large gap in the bandwidth between MPLS IPVPN and Internet
Using small-bandwidth, important applications mainly over the MPLS IPVPN route: ERP, voice
Using large-bandwidth applications (such as video conferencing, file transmission) mainly over the Internet IPSec route

Solutions:

Using SLA (Packet loss, Latency, Jitter) to solve network switching conditions, we can reach a high level of transmission quality and reduce downtime.
SD-WAN can be distributed over multiple application layers, allowing Internet IPSec or MPLS IPVPN to be used for transmission when the traffic pattern is video conferencing, meaning that there is no need to use IP to distribute network routes.
Chunghwa Telecom has set up an SD-WAN end-to-end Qos mechanism; and with its ample experience in Qos planning, it can ensure quality for applications even during high traffic.

Strength
