Huawei's NG-WAN Solution: A New Era in Network Management

Huawei's NG-WAN (Next-Generation Wide Area Network) solution has marked a significant milestone by being widely adopted commercially, driving the growth of network operators in an increasingly AI-driven future. John Cai, Vice President of Huawei’s Data Communication Product Line, highlighted this development during the Net5.5G Intelligent IP Network Summit held on October 13. Cai emphasized the critical role artificial intelligence (AI) plays as operators face a fast-evolving landscape, characterized by uncertainty and rapid change.

The Need for Security and Resilience

The NG-WAN solution employs a robust multi-layer security system that extends from device level, through connection level, to service level. At the device level, Huawei's innovative RDR (Real-time Detection and Response) system operates based on independent Threat Protection Units (TPUs) and behavioral analysis algorithms, effectively detecting over 95% of threats and identifying APTs (Advanced Persistent Threats) within minutes. In recent tests with a major Chinese telecom operator, these TPUs successfully thwarted 324 attacks from eight different countries during a three-month deployment.

Groundbreaking Technology

At the connection layer, the PQC algorithm has been implemented across all Huawei devices, improving encryption efficiency by 40%. An industry-first integrated Quantum Key Distribution (QKD) solution has also been introduced, allowing for three-channel integration, which has reduced network expansion costs by 60% and surpassed the previous transmission range limit of 80 kilometers. This was exemplified by a project in Macau, where Huawei partnered with a local operator to introduce the world's first quantum-secure target network, resulting in a 50% increase in revenue from dedicated lines.

The service layer benefits from the '1+4' multi-faceted protection concept, significantly reducing the response time to DDoS attacks from one minute to under five seconds. Moreover, it enhances the detection of unknown threats by 15%, achieving a 100% detection rate for ransomware and streamlining threat handling to under 30 minutes through the integrated Cyber Threat Security Operations Center (CT-SOC).

Harnessing AI for Enhanced Performance

As AI permeates core business processes, the NG-WAN solution is specifically designed to optimize computing power. The AI Fabric leverages network optimizations to increase computational performance, while a simplified two-layer Multi-Plane architecture quadruples network scalability and decreases hardware requirements by 30%. Additionally, the network-wide NPLB (Network Performance Lag Balancer) maintains a connection utilization of 98%, bolstering training and inference performance by over 7%.

This coordination between network efficiency and computational capacity is demonstrated by Huawei’s lossless STARnet algorithm, achieving zero packet loss over a transmission distance of 1,000 kilometers while maintaining a processing efficiency of over 96%. This advancement allows operators to provide on-site experiences remotely, accelerating the monetization of services in business applications. For instance, this solution was deployed by a Chinese operator to support a healthcare initiative, resulting in a 30% reduction in hospital computing costs while quintupling the average revenue per user (ARPU) for dedicated lines.

Achieving Network Autonomy

Huawei's autonomous network architecture, encapsulated in the “One Map, One Brain” approach, has reached Automation Level 4 (AN L4) across various operational scenarios including fault handling, network changes, optimization, and security. This level of autonomy facilitates a comprehensive automation strategy for network modifications, encompassing configuration checks, simulations, and comparisons while ensuring quick response to security threats through instantaneous intrusion detection and attack traceability.

More than 60 network operators worldwide have already implemented the NG-WAN solution, showcasing how Huawei's continual innovations in lossless computational efficiency, multi-layer security, and network autonomy are transitioning operators' AI strategies from mere efficiency optimization to value creation. This sets a resilient network foundation suitable for the AI age and positions Huawei as a leader in the next generation of secure, efficient carrier networks.

As we look ahead, Huawei is committed to collaborating with industry partners to accelerate the global adoption of the NG-WAN solution, contributing to the establishment of secure, resilient, intelligent, and efficient next-generation carrier networks that advance growth in the AI era.
