Central State-Owned Enterprises
Does the digital transformation of central enterprises encounter network lag? Guanglian breaks through with a 'smart network'
May.30.2025
At 2 o'clock in the morning, Director Li (pseudonym), the IT operation and maintenance manager of a state-owned enterprise's data technology company, was awakened by a sudden ringing of the phone. The synchronization of production data between the headquarters data center and the South China region has been interrupted again, and the automated production line is about to shut down! "The anxious voice of the on duty engineer came from the other end of the phone. This is the third business crisis caused by network issues this month. Director Li stared at the flashing red alarm on the monitoring screen and realized that the traditional MPLS dedicated line architecture could no longer support the group's digital transformation.
The stumbling block of digital transformation
This Fortune 500 state-owned enterprise giant is promoting the "One Cloud" strategy to unify and control over more than 30 BU units. But when the OA system was migrated to the cloud, problems began to arise one after another:
Key Meeting Stuck into PPT: Hong Kong and South China Teams' 4K Video Meetings Frequently Stuck, MPLS Dedicated Line Bandwidth Shortages
Millions of cost black holes: high dedicated line fees are paid every year, but the utilization rate of Internet links is less than 40%
The operation and maintenance team is exhausted: every time a new business unit is added, VRF needs to be manually configured, and a cross BU troubleshooting requires coordination with 5 departments
Compliance Countdown Pressure: As the deadline for the State owned Assets Supervision and Administration Commission's IPv6 transformation approaches, traditional devices are unable to support dual stack protocols
Just like pulling a high-speed train with a carriage, our network architecture has slowed down the digitalization process of the entire group, "Director Li bluntly stated at the review meeting.
Breaking through: A 'heart bypass surgery' for SDWAN
After the arrival of the Guanglian Century technology team, it took three weeks to complete the "physical examination" of the entire network and issue targeted prescriptions:
1. Intelligent vascular remodeling
Deploy "dual active brain" (main and standby controllers) in Beijing, Shanghai and Guangzhou data center, 34 key sites use MPLS+Internet dual blood vessels for blood supply, key businesses (such as production line data) automatically go through MPLS "VIP channel", staff training videos and other traffic intelligent switch to the Internet
2. Safe Isolation Cabin Plan
Using EVPN+VXLAN technology to build dedicated communication cabins for the five business units, financial data and medical information are physically isolated, completely eliminating the risk of cross business data leakage. The SM series algorithm of Guomi encrypts the Internet link in the whole process, and the VRF logic isolation ensures that the flow is controllable, which fully meets the level III security requirements of equal protection 2.0.
3. 24-hour AI monitoring
After deploying the iMaster NCE controller, the operations team discovered that the system had automatically switched routes and generated diagnostic reports when there was a link fluctuation at a certain site in Shanghai. During a line interruption, the backup 5G link was taken over within 200 milliseconds, and the production line had zero sensing.
The Transformation from "Firefighter" to "Strategic Advisor"
Since the implementation of the project three months ago, there has been a significant improvement in network issues: the lag rate of video conferences has decreased by 92%, and the data synchronization speed of overseas factories has increased by 8 times. In addition, the utilization rate of Internet bandwidth has soared from 40% to 64%, which is expected to save more than 10 million yuan of dedicated line fees annually. The IPv6 upgrade has also reached the standard six months ahead of schedule, becoming a benchmark case for the State owned Assets Supervision and Administration Commission.
What surprised Director Li the most was that the group network, which originally required a team of 20 people to maintain, can now be globally controlled by 5 people through a mobile app. "We can finally free up our hands to develop a new business AI application platform," he said.
The internet is not just a channel, but also a digital vitality
Looking back at the early morning malfunction now, it was actually an opportunity for transformation, "Director Li presented a set of data at the project acceptance meeting: the production efficiency of the group's intelligent manufacturing base has increased by 17%, which is precisely the chemical reaction generated by a highly reliable and intelligent network.
Optical Union Century is copying this plan to the network upgrading and transformation of other state-owned enterprises, and using "SDWAN" to help the Internet closure of state-owned enterprises. When digital transformation enters the deep waters, every evolution of network architecture is reshaping the DNA of enterprise life.
