Case study on network optimization of slow access to domestic ERP servers by overseas users//Global IPLC service provider of Shigeng Communication

一、With the development of global business, more and more enterprises are facing the need for overseas branches or partners to access ERP systems located locally in China. However, cross-border network access often faces problems such as high latency, severe packet loss, and slow speed, which seriously affect business efficiency. This article will analyze the reasons and optimization solutions for slow access to domestic ERP servers by overseas users through a practical case.

1. Case background

A manufacturing enterprise headquartered in Shanghai uses the UFIDA NC system as its core ERP platform, with servers deployed in the Shanghai data center. The company has branches in Southeast Asia (Singapore, Malaysia), Europe (Germany), and North America (United States), with approximately 200 overseas users. With the expansion of business, overseas users generally reflect that:

Logging into the ERP system is slow, sometimes taking 2-3 minutes to enter

The operation response is significantly delayed, and simple document saving takes 10-15 seconds

Frequent connection interruptions during peak hours

The report export function is basically unusable

2. Problem diagnosis

1. Network link testing

By testing the network connections in three regions using traceroute and ping tools, it was found that:

Average latency: 180ms in Southeast Asia, 320ms in Europe, 280ms in North America

Packet loss rate: average 5-8%, can reach up to 15% during peak hours

Routing hops: generally between 18-22 hops, with some routes bypassing the United States before returning to Asia

2. Analysis of bandwidth usage

Monitoring shows that the utilization rate of international export bandwidth during business hours (9:00-11:00 local time) is over 85%, indicating significant congestion.

3. Application layer analysis

The ERP system is not optimized for high latency environments, and frequent small packet requests exacerbate the impact of latency

Lack of compression mechanism, slow loading of page elements and static resources

Database queries are not cached, and overseas users need to interact with domestic servers every time they operate

4. Impact of security policies

The deep packet inspection (DPI) of firewalls and frequent SSL renegotiation add additional latency.

3. Optimize solutions

1. Network architecture optimization

a. Deploying Global Acceleration Services

Adopting global acceleration solutions from Alibaba Cloud or Tencent Cloud, utilizing their overseas POP points to optimize routing

By using BGP Anycast technology, users can access the optimal nodes nearby

b. Dedicated line/VPN replaces public network

Southeast Asian branch: Deploy MPLS dedicated line, latency reduced to below 80ms

European and American branches: using IPSec VPN over SD-WAN to dynamically select the optimal path

c. CDN Static Resource Distribution

Distribute static resources (JS/CSS/images) from ERP to overseas nodes through CDN

Enable HTTP/2 and Brotli compression to improve transmission efficiency

2. Application layer optimization

a. Front end optimization

Implement front-end caching to reduce duplicate requests

Adopting asynchronous loading and lazy loading techniques

Merge API requests to reduce the number of requests

b. Backend optimization

Add Redis caching layer to cache commonly used data

Optimize database queries and add appropriate indexes

Implement paging and incremental loading mechanisms

c. Protocol optimization

Enable QUIC protocol instead of TCP to improve performance in high latency environments

Adjust TCP window size and KeepAlive parameters

3. Architecture improvement

a. Regional distributed deployment

Deploy read-only replicas in Southeast Asia (Singapore) to handle query requests

Key businesses are still being written back to the central database to ensure data consistency

b. Data synchronization strategy

Implementing Near Real Time Data Synchronization with GoldenGate

Non critical report data allows for a certain delay

4. Other optimizations

Adjust firewall policies to reduce unnecessary deep packet inspection

Optimize SSL configuration, enable session reuse and OCSP Sampling

Implement QoS strategy and prioritize ensuring ERP traffic

Through this case, it can be seen that solving the problem of slow overseas access to domestic ERP requires systematic planning and multi-faceted optimization measures. Enterprises should choose the most suitable optimization combination plan based on their own business characteristics, user distribution, and IT budget.
