Token overseas dedicated line: data cannot be exported, cross-border privacy is more secure?? Solution//Global IPLC service provider of Shigeng Communication

一、With the acceleration of the global application of AI big models, Token (token) going global is becoming a new trend in digital trade. Unlike traditional data or model exports, the core logic of Token exports is "electricity does not leave the country, computing power does not leave the country, and value flows globally" - delivering low-cost computing power and mature model capabilities from China to overseas users in the form of standardized inference services across borders.

However, the compliance and privacy security of cross-border data transmission have always been the Damocles sword hanging over the heads of enterprises. How to achieve efficient and secure cross-border token services while ensuring that data is not exported? The combination of network dedicated lines and physical isolation architecture provides the answer.

1. Why does Token rely on compliance dedicated lines for going global?

The typical call chain for Token going global is: overseas users initiate requests → requests are transmitted to domestic computing centers through cross-border networks → models complete inference to generate Tokens → results are returned to overseas users in the original path. This process may seem simple, but it faces three core challenges:

Compliance red line: According to regulations such as the "Measures for Security Assessment of Data Export" and the "Personal Information Protection Law", cross-border transfers involving personal information or important data must go through strict approval processes. Token calls can reach tens of thousands or even billions of times per day, and the traditional "approval by approval" model is completely impractical.

Delay bottleneck: Cross ocean transmission naturally has a physical delay of hundreds of milliseconds. If encountering submarine cable congestion or packet loss retransmission, the experience of real-time interactive AI applications (such as AI toys and intelligent customer service) will be greatly reduced.

Privacy leakage risk: If sensitive information such as prompt words and business parameters of users are intercepted during transmission or storage, it will cause serious data security incidents.

The compliant cross-border dedicated line is the infrastructure foundation for solving these problems.

2. The 'data processing' mode: a compliant architecture where data cannot be exported from the end

At present, China has explored a compliance path centered on "data processing" (also known as "digital bonded zones"). This model draws on the logic of bonded zones in international trade, establishing physically isolated offshore data zones within the country to achieve "closed-loop processing within the overseas data zone, without flowing into the country, and deleting when used up".

The specific operation process is as follows:

Exclusive channel entry: overseas users' requests enter the offshore zone through the compliant international data line (such as direct cable), which is physically isolated from the domestic public Internet.

Special zone computing processing: The entire process of reasoning, scheduling, and computation is completed within the special zone, and the internal system defaults to no access to the raw data.

Clear result feedback: The token generated by inference is returned to overseas through the same channel, and the original data and intermediate logs are automatically and irreversibly deleted.

Taking the Shantou Overseas Chinese Experimental Zone in Guangdong Province as an example, as the first area in China to implement the "data processing" pilot program, it relies on the Shantou International Submarine Cable Landing Station (with a direct connection to Southeast Asia delay of only 32.7 milliseconds), and has fully implemented the full chain loop of "offshore data center → production token → overseas call → data compliance transmission". The daily average token call volume has rapidly increased from 100 million to tens of billions.

3. The technical architecture of cross-border dedicated lines: dual guarantee of low latency and high security

The enterprise level Token overseas dedicated line must meet the following technical requirements:

Physical isolation transmission architecture: using dedicated cross-border encrypted links to avoid public network congestion and interference, ensuring complete isolation of data flow from domestic networks.

Global intelligent scheduling: Through CDN edge nodes and global routing systems, real-time detection of link conditions and dynamic selection of the lowest latency path can compress cross ocean latency to tens of milliseconds.

High speed transmission algorithm: Adopting TCP high-speed transmission algorithm and data compression technology, optimizing congestion control mechanism, improving bandwidth utilization and high concurrency carrying capacity.

Full link encryption: TLS 1.2/1.3 protocol is mandatory for the transport layer, AES-256 encryption is used for the storage layer, and the key is independently managed by the enterprise.

In addition, companies such as FiberHome Communications have overcome the core technology of 800G cross ocean transmission, with a single fiber capacity of 26.4T and a stable transmission capability over a long distance of 6000 kilometers, which can directly cover the interconnection needs of major intercontinental computing nodes, providing a low-cost and larger bandwidth cross-border digital channel for Token to go global.

4. Deep defense system for privacy and security

In addition to isolation and encryption at the network level, enterprises also need to establish a full chain privacy protection system:

Data classification and desensitization: Data is divided into three levels: core, sensitive, and ordinary. It is strictly prohibited to upload core and sensitive data without desensitization; Prohibited outbound data includes personal biometric features, etc.

Confidential computing reinforcement: Deploy confidential computing environments such as TEE (Trusted Execution Environment) to prevent data leakage during the computation process, making plaintext invisible to platform administrators.

Full link audit and certification: The independent audit system records the entire process of data entry, routing, computation, and output, with logs retained for no less than 6 months, meeting the requirements of two-way supervision.

Minimum permission control for intelligent agents: binding identity and minimum permission authorization for intelligent agents, prohibiting cross regional access, and continuously monitoring abnormal external behavior.

Conclusion

The competition for Token going global has shifted from a simple "model effect competition" to a comprehensive competition of "compliance capability+security base". By leveraging the benefits of the "data processing" policy and the compliance cross-border dedicated line, enterprises can transform the cost advantage of Chinese computing power into a competitive advantage in the global market while ensuring that "data is not exported and privacy is more secure".
