The advent of the 5G and cloud era is driving the emergence of a large number of innovative services, such as VR/AR, live broadcast, and autonomous driving. And as data increases in volume and cyber security threats become more complex, the technical landscape of data centers changes at an unprecedented speed. Huawei iMaster NCE-Fabric — an autonomous driving network management and control system for data center networks — integrates management, control, analysis, and AI functions. In addition, to realize business intent, it provides network resource cloudification, full-lifecycle network automation, and data analysis-driven intelligent fault remediation capabilities, improving service provisioning and O&M efficiency.
Huawei provides an industry-leading automatic and intelligent solution for telco cloud network functions virtualization infrastructure (NFVI) and Enterprise Data Center (EDC)/Internet Data Center (IDC) scenarios, redefining automatic deployment, service provisioning, and O&M of data center networks.
After receiving a complaint, the call center or NOC remotely demarcates and locates the fault and accurately dispatches work orders (WOs) to avoid unnecessary field visits. NCE (Access Domain) dynamically restores the service topology, and provides 24/7 playback of KPIs to automatically identify abnormal indicators.
PON faults account for 25% of all faults. Due to long and complex optical lines, engineers need to troubleshoot faults onsite, which is inefficient and affects user satisfaction. NCE (Access Domain) uses the OLT to collect data and extract characteristics of ONTs, identifies fault types based on multi-KPI correlation analysis, and restores the ODN topology. With these features, NCE (Access Domain) accurately identifies the causes of faults on the feeder, distribution, and drop fibers. NCE (Access Domain) also supports automatic creation of WOs, improving efficiency of troubleshooting PON faults.
NCE identifies weak optical signals on feeder, distribution, and drop fibers, and determines whether the signals affect services based on user experience, helping carriers decide on rectification priority. It also outputs a weak optical signal rectification report, which provides the fault location (feeder, distribution, or drop fiber), fault object location, number of affected subscribers, whether services are affected, and possible causes, helping customers quickly rectify faults.
