Bank A is a global bank with hundreds of branches and offices around the world. Due to its expanding business and increasing network demands, Bank A is facing issues such as cross-regional interconnections, inefficient data transfer, and network security. In order to improve the performance and stability of network connectivity between branches and to guarantee the secure transmission of sensitive data, Bank A decided to adopt SDWAN technology to improve its network architecture.

I. Requirements Analysis

Bank A’s branches are located in different regions of the world and face the following needs and challenges:
1. Network connection performance: Stable and high-speed network connection is needed between branches to ensure the efficiency of daily business and data transmission.

2. Data security: Banks are involved in a large amount of sensitive customer data, so network security is a primary concern and the security and privacy of data transmission needs to be guaranteed.

3. Complex network management: With many branches, traditional network management and configuration is complicated, and there is a need to simplify the network management process and reduce maintenance costs.

II. SDWAN Design and Deployment

Bank A selected a reliable SDWAN solution provider and conducted comprehensive network planning and design.
1. Connection Types: For branches in different regions, different connection types were selected based on network requirements, including MPLS leased lines, Internet connections, and 4G/5G wireless connections to meet the bandwidth and network connection performance needs of each region.

2. Device Deployment: In each branch, SDWAN edge devices, including SDWAN routers and security devices, are deployed. These devices are able to intelligently select the best network path and use encryption to secure data transmission.

3.Network Optimization: Through SDWAN technology, network traffic is optimized, and the optimal path is dynamically selected to avoid network congestion and packet loss, and to improve network transmission efficiency.

4. Security Policy: Unified security policy is configured on SDWAN devices, including firewall, intrusion detection and data encryption functions, to guarantee the safe transmission of sensitive data.

III. Data Migration and Training

After the SDWAN equipment was deployed, Bank A carried out data migration and network equipment configuration to ensure that each branch could connect to the SDWAN network smoothly. At the same time, the IT team was trained so that they could skillfully operate and manage the SDWAN equipment to ensure stable network operation.

IV. Monitoring and Optimization

To ensure the high performance and stable operation of the SDWAN network, Bank A implemented real-time network monitoring and optimization measures. Through the SDWAN controller, it monitors network traffic and performance indicators in real time, identifies and solves potential problems in a timely manner, and guarantees the quality of network connections between branches.

V. Effects and Advantages

Through SDWAN networking, Bank A has achieved the following advantages and effects:
1. High-performance network connection: SDWAN technology helps optimize network traffic, improve the performance of network connection between branches, and accelerate data transmission speed.

2. Data security guarantee: SDWAN devices provide multi-level security policies to guarantee the safe transmission of sensitive data and improve network security.

3. Simplified Network Management: SDWAN controllers provide centralized network management and configuration, simplifying the network management process and reducing maintenance costs.

4. High Reliability and Flexibility: SDWAN technology dynamically selects the optimal path to avoid a single point of failure, improving network reliability and flexibility.

VI. Summary

With the SDWAN networking solution, Bank A successfully realizes high-performance, secure and stable network connection between branches, and improves the efficiency of global network collaboration and business responsiveness. sDWAN technology provides a reliable network infrastructure and security for the development of banking business, and lays a solid foundation for the bank’s global business expansion.
