Dedicated China Connect SD-WAN
Trusted Advisor for IT & Telecommunications Sourcing
An SD-WAN that legally bypasses the Great Firewall of China
Legally compliant communication via the Great Firewall
How the legal bypass of the Great Firewall works.
Many companies face the challenge of securely extending their international networks to China. Traditional VPNs are increasingly being blocked there, and MPLS is expensive and time-consuming to deploy. SAVECALL Dedicated China Connect offers a legal and high-performance alternative.
In a nutshell:
- Legally compliant: officially licensed SD-WAN solution that is not blocked by the Great Firewall.
- Fast and stable: availability of 99.9 percent and average ping times of around 200 milliseconds.
- Efficient: bandwidths can be flexibly adjusted and packet losses of less than one percent.
- Simple integration: connection via local cloud gateways in China and Europe.
- Cost advantage: significantly cheaper and faster to implement than MPLS.
The solution: SAVECALL Dedicated China Connect utilizes China Telecom’s global backbone, combined with advanced SD-WAN technology, for secure end-to-end connections between Europe and China, without risk and without outages.
What this article covers: Why Site Connectivity to China is difficult, how Savecall Dedicated China Connect works technically, and how you can secure your international Site Connectivity between Europe and China.
Why Site Connectivity to China is difficult
China is still the world’s workbench. At the same time, with a population of more than one billion people, China is also one of the largest consumer markets. As a result, many German companies are active in China for production or sales and have set up plants or offices there. Companies need to extend their WAN to China, but this is easier said than done. New regulation for IPsec traffic: many companies had been doing this using VPNs, but the Chinese government has imposed restrictions on IPsec traffic and since then has regularly shut down IPsec connections arbitrarily and without notice.
One way to extend the WAN to China is to switch an MPLS connection in China. An MPLS connection to China is reliable and meets the requirements of the Chinese government, but it is too expensive and can take six months or longer to deploy.
A new option for Site Connectivity to China
Now there is a better option for your WAN connectivity to and from China. Savecall Dedicated China Connect is an SD-WAN solution that builds on existing Internet lines. How does Savecall Dedicated China Connect work? Outside of China, the global cloud backbone of China Telecom is used. The respective locations are equipped with SD-WAN hardware, which connects to the nearest cloud gateway. Of course, you can also use your own encryption, without the key having to be deposited with a Chinese authority. The data transmission of Savecall Dedicated China Connect is not blocked by the “Great Firewall of China” and performs similarly to MPLS.
Legally circumventing the Great Firewall of China
Within the legal framework and officially licensed. From the company’s point of view, only an intra-Chinese connection is established between an office location and the cloud gateway. Suppose a company has both a location in Berlin and one in Shanghai. In Shanghai, the SD-WAN hardware connects to the cloud gateway in Shanghai. In Berlin, the SD-WAN hardware connects to the cloud gateway in Frankfurt. The two cloud gateways are connected via China Telecom’s cloud backbone. This creates a high-performance end-to-end connection.
How SAVECALL supports your Site Connectivity to China
Technical data of Savecall Dedicated China Connect: availability of 99.9 percent, ping times in China of around 200 milliseconds depending on region, packet losses of less than 1 percent, and flexibly adjustable bandwidths depending on data transmission requirements. SAVECALL’s Dedicated China Connect offers an officially licensed, legally compliant alternative to VPN and MPLS and supports companies from planning through the ongoing operation of their Site Connectivity between Europe and China.
Conclusion
Don’t wait until your China IPsec VPN is also switched off. A officially licensed SD-WAN solution like Savecall Dedicated China Connect legally bypasses the Great Firewall while delivering performance close to MPLS, at significantly lower cost and with faster deployment.
Set the course now to be able to communicate securely, stably and legally with your locations in China in the future.

Frequently asked questions about Savecall Dedicated China Connect
The Chinese government has imposed restrictions on IPsec traffic and since then regularly shuts down IPsec connections arbitrarily and without notice. Companies relying on traditional VPNs therefore risk a sudden connection failure to their Chinese sites at any time. A licensed solution such as SAVECALL Dedicated China Connect avoids this risk because it operates within the legal framework instead of relying on a legally uncertain workaround.
An MPLS connection to China is reliable and meets the requirements of the Chinese government, but it is expensive and can take six months or longer to deploy. For companies that need a fast, cost-efficient connection, this is often not practical. SAVECALL Dedicated China Connect instead builds on existing Internet lines and is therefore significantly cheaper and faster to implement.
Outside of China, the global cloud backbone of China Telecom is used. The respective locations receive SD-WAN hardware that connects to the nearest cloud gateway. From the company’s perspective, this only establishes an intra-Chinese connection between the office location and the cloud gateway, while the two cloud gateways are connected via China Telecom’s backbone. This creates a high-performance end-to-end connection without being blocked by the Great Firewall.
Yes. In addition to the security provided by the licensed China Telecom backbone, your own encryption can be used without the key having to be deposited with a Chinese authority. This combines the legal certainty of the solution with the data control companies need for sensitive communication.
The solution achieves availability of 99.9 percent, ping times in China of around 200 milliseconds depending on the region, and packet losses of less than 1 percent. Bandwidth can be flexibly adjusted depending on data transmission requirements. This means performance is similar to MPLS, but at significantly lower cost and with faster deployment.
SAVECALL’s Dedicated China Connect offers an officially licensed, legally compliant SD-WAN solution for Site Connectivity between Europe and China. Rather than evaluating individual technologies in isolation, SAVECALL compares suitable options for your locations in a vendor-neutral way and supports implementation from planning through ongoing operation, so you can communicate securely, stably and legally with your Chinese sites.
