Huawei LAN-WAN Converged Network Solution Empowers Sri Lanka Customs' Digital Transformation

Sri Lanka Customs is the national authority responsible for border control, revenue collection, trade facilitation, and the enforcement of customs law across the country. Its operations extend from the headquarters in Colombo to regional offices, seaports, and airports, all of which depend on continuous access to centralized customs systems for declaration processing, cargo clearance, and inspection. To support the continued expansion of digital customs services, Sri Lanka Customs planned to modernize its nationwide network into a single, centrally managed environment. Huawei provided a complete LAN-WAN converged solution comprising an SD-WAN wide area network, a full-fledged campus network at headquarters, simplified LAN infrastructure at branch sites, and unified management through iMaster NCE-Campus.

Challenges

Sri Lanka Customs faced four core challenges. First, no centralized management, where the absence of a unified controller and analyzer limited network visibility, monitoring, and management efficiency across branches distributed throughout the country. Second, limited reliability and scalability, where the lack of intelligent traffic steering meant application performance and service quality could not be optimized consistently across multiple locations. Third, complex operations and maintenance, where manual configuration, fault diagnosis, and site deployment required considerable effort and specialized expertise, slowing the rollout of new sites and the resolution of network incidents. Finally, high network operating costs, where dependence on costly leased links increased wide area network expenditure and reduced overall cost efficiency.

With digital customs services continuing to expand and trade volumes growing across ports and airports, Sri Lanka Customs needed a modern network solution capable of supporting future service growth — not only resolving current management and cost issues, but also laying a solid foundation for further digital transformation of national customs operations.

Solution

Huawei provided the LAN-WAN Converged SD-WAN Solution tailored to Sri Lanka Customs' specific requirements, including AR series SD-WAN gateways at headquarters and branch sites, CloudEngine campus switches, AirEngine Wi-Fi 7 access points, and the iMaster NCE-Campus unified management platform.

Conventional wide area networks rely on a single transport type, with every site configured device by device and faults located manually. Branch sites operate as independent islands, each requiring an on-site engineer for commissioning and troubleshooting, and campus and wide area networks are managed by separate tools and separate teams. This model is slow to scale, expensive to operate, and offers little end-to-end visibility of service quality.

The Huawei LAN-WAN Converged SD-WAN Solution addressed these pain points through the following capabilities:

• Unified LAN and WAN Management: iMaster NCE-Campus manages campus and wide area network devices from a single platform, delivering end-to-end visibility, monitoring, and policy control across the entire network.

• Hybrid Uplinks with Intelligent Traffic Steering: Private line, Internet, and 5G/LTE links are used together as an SD-WAN overlay, with application-aware path selection and automatic failover to maintain service quality between sites.

• Zero-Touch Provisioning: New branch sites are brought online from a central configuration template, reducing dependence on specialized on-site expertise and accelerating nationwide rollout.

• AI-Powered Intelligent O&M: Proactive fault detection and root-cause analysis shorten the time required to locate and resolve network issues, replacing manual, device-by-device diagnosis.

• Full-Fledged Headquarters Campus Network: A layered campus design with core and aggregation switches, access switches, and Wi-Fi 7 wireless coverage supports high-density wired and wireless user access at headquarters.

• Simplified Branch Infrastructure: Branch sites use a lightweight LAN design based on the SD-WAN gateway and access switching, with Wi-Fi 7 wireless deployed at selected regional offices where mobile access is required.

Based on the operational characteristics of the customs environment, Huawei provided a customized design to ensure seamless integration with the existing customs application systems and a phased migration approach that safeguarded service continuity at ports and airports throughout the transition.

Business Value

By deploying the Huawei LAN-WAN Converged SD-WAN Solution, Sri Lanka Customs achieved significant business value:

Enterprise IT System Benefits

• Centralized Network Management: SD-WAN and campus network devices are managed through a unified platform, providing centralized visibility, monitoring, and management of the entire network from a single interface.

• Reliable and Secure Connectivity: Stable, high-performance connections between headquarters, ports, airports, and regional offices, with intelligent traffic optimization, link redundancy, and encrypted VPN transport across all sites.

• LAN-WAN Convergence: Campus and wide area networks are operated as one converged network, eliminating the need for separate management tools and streamlining daily operations.

• Rapid Site Deployment: Zero-Touch Provisioning and automated deployment templates enable new sites to be provisioned in hours rather than days, with minimal manual intervention.

Overall Business Benefits

• Operational Efficiency Improvement: A unified management platform and automated O&M significantly reduce operational complexity and shorten fault response times across the national network.

• Cost Optimization: Hybrid uplinks reduce dependence on costly leased links, while automation lowers the operational and travel costs associated with distributed site management.

• Service Continuity: Redundant transport and intelligent path selection help maintain uninterrupted access to customs systems for declaration processing and cargo clearance at critical trade gateways.

• Future Scalability: A standardized network foundation supports the continued expansion of digital customs services and the rapid onboarding of additional sites.

Sri Lanka Customs will continue to deepen its cooperation with Huawei, building on the converged network platform to support further digitalization of customs services, strengthen trade facilitation, and contribute to the growth of the national economy.
