Cross border network optimization: Vietnamese users??? Solution//Global IPLC service provider of Shigeng Communication

一、With the increasingly close economic and trade relations between China and Vietnam, more and more enterprises are facing the problem of "inability to connect, slow speed, and constant disconnection" when Vietnamese users access domestic core business systems (such as OA, ERP, CRM). A regular login may take several minutes to complete, video conferencing freezes into a "mosaic art", and file transfers are repeatedly interrupted. This not only seriously affects the work efficiency of the Vietnamese team, but also directly slows down the overall operational rhythm of the enterprise.

At its root, the essence of this problem is the result of the combined effects of network latency, data packet loss, and application architecture mismatch. This article aims to systematically analyze the core pain points of Vietnamese users accessing Chinese resources and provide a complete solution from technology to management.

1. Root cause of malfunction: Why is the user experience in Vietnam poor?

To solve the problem, the first step is to accurately locate the bottleneck. The poor access of Vietnamese users is caused by the combination of multiple obstacles.

Specific manifestations and root causes of problem hierarchy

Layer 1: Physical and Network Bottlenecks 1. Non optimal Routing: Data often travels around Hong Kong or Singapore, resulting in complex paths and a sudden increase in basic latency.

2. International bandwidth congestion: During peak hours across borders (such as weekday mornings), public links are congested, and packet loss rates can reach 5% -15%.

3. Fluctuations in local operators: The quality of interconnection between Vietnam's local network service providers (VNPT, Viettel, etc.) and China is unstable.

Layer 2: Application and Protocol Bottleneck 1. Low Protocol Efficiency: Traditional TCP protocol experiences heavy transmission in high latency and high packet loss environments, resulting in a sharp decrease in effective throughput.

2. Application architecture limitations: Most domestic systems are designed for internal networks, with pages containing a large number of small file requests and high latency penalties for each round trip.

Layer 3: Security and Policy Bottleneck 1. Firewall Blocking: Enterprise security policies often default to blocking access from unknown overseas IPs or non essential ports.

2. Compliance risk: Unassessed cross-border data flows may violate China's Data Security Law and local data regulations in Vietnam.

2. Core solution: Building a trinity network of "intelligence, acceleration, and compliance"

In response to the above pain points, modern enterprises should no longer rely on traditional single international dedicated lines or ordinary VPNs, but should build an intelligent hybrid network architecture. The current mainstream solutions can be summarized as follows:

Solution type, core principles, advantages, applicable scenarios, key considerations

SD-WAN (Software Defined Wide Area Network) deploys dedicated devices, intelligently aggregates and dynamically selects multiple lines, and schedules traffic in real-time to the optimal path. High cost-effectiveness, fast deployment, flexibility, and significantly improved stability. The preferred choice for overseas enterprises, especially those with multiple Vietnamese sites and cost sensitivity. Need to evaluate the quality of service providers' POP points (access points) in Vietnam and the depth of cooperation with local operators.

Cloud native global acceleration utilizes Segong Communication's nodes in China and Vietnam to achieve acceleration through private protocols and intelligent scheduling. No maintenance, elastic scalability, seamless integration with cloud services. The core business system has been deployed in the public cloud, or plans are underway to migrate some services (such as file caching) to the cloud. Ensure that cloud service providers have high-quality nodes in Vietnam; Indirectly accelerating the deployment of purely localized systems.

The integrated SaaS acceleration solution is provided by OA/ERP vendors or professional Segon Communications. Optimal experience, deep integration of applications, simple delivery, and built-in security compliance. Use mainstream standardized SaaS or specific vendor products (such as UFIDA and Kingdee Cloud) to pursue the best experience and fast launch. The scheme is bound to specific vendors, resulting in relatively low flexibility.

Technical Analysis: Why SD-WAN is the Mainstream Choice?

The progressiveness of SD-WAN lies in its "application awareness" and "dynamic healing" capabilities.

Intelligent routing and load balancing: It can monitor the quality of each link in real-time (latency, packet loss, jitter). When an increase in packet loss rate is detected on a certain line, critical traffic such as OA and video conferencing can be switched to a better path within milliseconds.

Protocol and transmission optimization: integrating forward error correction (FEC), data compression, TCP optimization (such as BBR algorithm) and other technologies. Even if packet loss occurs, it can be fixed through algorithms to avoid retransmission, greatly improving the smoothness of audio and video and the success rate of file transfer.

3. Practical Case: Network Transformation of Vietnamese Manufacturing Enterprises

Enterprise background: An electronic manufacturing enterprise in southern China has a large production base in Haiphong, Vietnam.

Core pain point: The Vietnamese factory accessing the ERP system of the Shenzhen headquarters experienced a delay of up to 220ms and a packet loss rate of 8%, resulting in delayed production order synchronization and inaccurate inventory data. Video weekly meetings experience severe lag and low communication efficiency.

Solution:

Deploying SD-WAN: Deploying all-in-one machines at the Shenzhen headquarters and coastal defense factory.

Hybrid link access: The Vietnamese factory is connected to a local business fiber optic cable and a 4G LTE as a hot backup.

Strategy configuration: Mark ERP and video conferencing traffic as the highest priority, and enable FEC and data compression.

Implementation effect:

Application response time: ERP operation latency has decreased from>5 seconds to<1.5 seconds.

Network quality: Average latency reduced to 95ms, packet loss rate<1%.

Business efficiency: Real time synchronization of production data, 40% reduction in monthly inventory time, smooth video conferencing.

Cost: The overall cost of ownership is about 35% lower compared to traditional MPLS dedicated line solutions.

4. Implementation Path and Best Practices

Diagnosis first, quantifying bottlenecks: using professional tools to measure end-to-end latency, jitter, packet loss rate, and critical application response time from Vietnam to China, establishing performance baselines.

Clarify requirements and select solutions: Based on business scale (number of users, data volume), key application types (OA/ERP/video), compliance requirements, and budget, choose the most suitable solution combination.

Balancing safety and compliance:

Zero trust access: Regardless of whether the user is in Vietnam or China, strict verification is required every time they access, and the principle of minimum privilege is implemented.

Data compliance: Clearly define cross-border data types, encrypt sensitive data, and ensure that the solution meets the data localization and export regulatory requirements of both China and Vietnam.

Step by step deployment, continuous optimization:

Pilot phase: Select a Vietnamese site for POC testing to verify the effectiveness of the plan.

Promotion stage: After success, promote the architecture to other sites.

Operation and maintenance phase: Establish a unified monitoring platform, continuously observe application experience, and optimize strategies based on business changes.

Conclusion

Optimizing the network for Vietnamese users to access domestic systems has changed from an "optional" option to a "mandatory" option to support global business operations. Its core lies in breaking away from the old idea of single bandwidth expansion, solving physical bottlenecks through intelligent network technologies such as SD-WAN, combining application layer optimization to improve protocol efficiency, and building an endogenous security compliance framework. Successful enterprises will use this to build a "digital highway" connecting China and Vietnam, eliminating physical distance as a barrier to collaboration and truly unleashing the potential and value of cross-border business.
