The big data driven networking (bDDN) can collect, store and analyze customer-based data. It enables intelligent network maintenance, management and operation by dynamically allocating resources to meet diverse customer needs through technologies, such as big data and artificial intelligence (AI). The architecture and mechanism for customer-oriented intelligent network operation (COINO) based on bDDN facilitate real-time network monitoring, service tracking and accurate matching of customer demands, thereby enhancing technical value. Additionally, COINO drives continuous business process transformation, reducing cost, improving efficiency, and elevating customer experience. This Recommendation specifies the architecture and mechanism for customer-oriented intelligent network operation based on bDDN.
