 How to effectively improve the speed of overseas office access to domestic ERP systems??? Solution//Global IPLC service provider of Shigeng Communication

一、In the globalized business landscape, many companies have set up branches overseas. However, network latency and bandwidth bottlenecks caused by geographical distance often result in overseas employees encountering difficulties such as slow page loading, operation lag, and data submission failures when accessing ERP systems deployed at domestic headquarters. This not only seriously slows down work efficiency and affects customer response speed, but also dampens employee morale.

This article will systematically analyze the root cause of the problem and provide a complete solution from low cost to high investment, helping enterprises effectively improve the experience of accessing domestic ERP systems overseas.

1. Root cause of the problem: Why is the speed slow?

Know yourself and know your enemy, you will never be defeated in a hundred battles. To solve the problem, it is necessary to first understand its causes:

Network latency: This is the main reason. The transmission of data between China and overseas requires passing through multiple international network nodes and operators, and the long physical distance inevitably leads to high latency. The round-trip time (RTT) for a data packet crossing the ocean can be as high as 200-500ms, far exceeding the tens of ms of local networks.

Bandwidth Bottleneck: International export bandwidth is a scarce resource. During peak business hours, congested international links can be like highways on holidays, resulting in packet loss and a sharp decrease in transmission speed.

The inefficiency of TCP protocol: Standard TCP protocol significantly reduces transmission rate to maintain connection stability when encountering high latency and packet loss, resulting in poor throughput performance in high latency networks.

Application layer design issues: Some ERP systems did not fully consider cross-border access scenarios during development, resulting in a large number of small and frequent requests (such as multiple handshakes and small queries). High latency can amplify the waiting time for each request, leading to extremely laggy overall experience.

2. Solution: A three-dimensional strategy from optimization to reconstruction

We can adopt a layered and progressive strategy to address challenges.

Level 1: Low cost optimization and soft acceleration (implemented immediately)

These plans have low investment and are suitable as preliminary optimization methods.

Local network environment optimization:

Ensure sufficient local bandwidth in overseas offices: First, eliminate local network issues. Use wired connections instead of Wi Fi to ensure good performance of routers and switches.

Use enterprise level VPN optimization: replace ordinary VPNs with commercial VPNs that support link optimization functions (such as the TCP mode optimization of OpenVPN). Although the improvement is limited, it is more stable than the bare connected public Internet.

Client and server-side tuning:

DNS optimization: Equip overseas offices with responsive local DNS servers (such as Cloudflare 1.1.1.1 or Google 8.8.8.8) to reduce domain name resolution time.

Client host configuration: Adjust TCP window size and other parameters to make it more suitable for Long Fat Network (LFN).

Optimization of application layer usage habits:

Train employees to avoid bandwidth intensive operations such as generating large reports and exporting bulk data during peak hours.

Fully utilize the client caching function of the ERP system to reduce unnecessary duplicate data requests.

Level 2: Mid level Solution - Acceleration and Proxy (Significant Effect)

This is the most cost-effective and mainstream solution.

Deploying SD-WAN (Software Defined Wide Area Network):

Principle: SD-WAN monitors the quality of multiple international links (such as MPLS, Internet, 4G/5G) in real time through intelligent routing technology, and automatically selects the optimal path to transmit ERP traffic. It usually has built-in technologies such as data compression, protocol optimization, data deduplication, and forward error correction (FEC), which can effectively combat latency and packet loss.

Advantages: Compared to traditional dedicated lines, the cost is significantly reduced, deployment is flexible, and the application experience can be significantly improved. It is currently the mainstream choice to solve this problem.

Deploy a cross-border network accelerator (Proxy):

Principle: Deploy acceleration nodes both domestically and internationally. Overseas users' requests are first connected to a local acceleration node through a high-quality link, which then communicates with domestic nodes through an optimized high-speed channel (possibly a dedicated tunnel) and ultimately accesses the ERP server. It has been specifically optimized for TCP and application layer protocols.

Advantages: Transparent application (no need to modify ERP system), easy deployment, and immediate acceleration effect. Many cloud service providers (such as Alibaba Cloud, Tencent Cloud, AWS) offer similar global acceleration products.

Level 3: Advanced Solution - Architecture Innovation (Once and for All)

For enterprises with high business dependency and large user base, the following solutions can be considered.

Leasing International Dedicated Line (MPLS VPN):

Principle: Lease an end-to-end private network channel from overseas offices to China. This line is isolated from other Internet traffic, providing stable bandwidth and extremely low latency and packet loss rates.

Advantages: Best performance, highest security and stability.

Disadvantages: Extremely expensive price, long deployment cycle, and poor flexibility. Usually chosen by large multinational corporations.

ERP system architecture renovation:

Application separation and caching: Deploy non core real-time components such as report servers and static file servers on clouds closer to users overseas. Establish read-only replicas or cached databases of domestic master databases overseas for query purposes, reducing cross-border real-time requests.

Cloud and Global Deployment: The Ultimate Solution. Migrating the entire ERP system to the cloud, utilizing the global backbone network and availability zone architecture of cloud service providers to achieve nearby access for global users. This solution has the largest modification, highest cost and technical complexity, but it can fundamentally solve the problem and improve system resilience.

summary

The slow speed of overseas visits to domestic ERP systems is a typical network engineering problem that is not unsolvable. Enterprises do not need to tolerate inefficient access experiences. Through scientific diagnosis and reasonable solution selection, especially the use of mature SD-WAN or cross-border network acceleration services, it is entirely possible to find the best balance between cost and performance, making data access across oceans "smooth and seamless", thereby empowering global business and enhancing international competitiveness.
