传统的带外测试方法，如基于隧道的OAM和TWAMP，需要管控侧显式配置

Traditional out-of-band testing methods, such as tunnel-based OAM and TWAMP, need to explicitly configure measurement tasks on the control side and manually maintain measurement tasks. Measurement tasks may deviate from actual business conditions. Fault location needs to be implemented segment by segment. Through in-band measurement, the above shortcomings can be effectively solved. The management and control system performs in-band performance detection based on real business flows, provides real-time, high-precision network end-to-end performance visualization and hop-by-hop fault delimitation capabilities, and improves the delimitation and location efficiency of performance degradation faults. In-band performance detection has the characteristics of low maintenance of measurement tasks, real service quality indicators, and rapid fault location; it can realize automatic identification of in-band service flow, and automatically identify end-to-end paths and services based on base station IP addresses and EPC/NGC IP addresses quality. In-band performance data can be quickly reported to the OMC system using the Telemetry protocol, providing a data analysis basis for intelligent operation and maintenance.

Traditional out-of-band test methods, such as tunnel-based OAM and TWAMP, need to control the side explicit configuration of measurement tasks, need manual maintenance of measurement tasks, measurement tasks and business reality may also be biased, fault positioning needs to be implemented segment by segment. The above deficiencies can be effectively solved by in-band measurement. The control system provides real-time, high-precision network end-to-end performance visualization and hop-by-hop fault demarcation capability based on real business flow, and improves the demarcation and positioning efficiency of performance degradation-type failures. In-band performance detection has the characteristics of small measurement task maintenance, real business quality index and rapid fault positioning, and can realize automatic identification of in-band business flow, and automatically identify end-to-end path and business quality according to base station IP address, EPC/NGC IP address. In-band performance data can be quickly escalated to the OMC system using the Telemetry protocol, providing a data analysis basis for intelligent operations.

Traditional out of band testing methods, such as OAM and twamp based on tunnel, need to configure measurement tasks explicitly on the control side, need to maintain measurement tasks manually, measurement tasks may deviate from the actual business situation, and fault location needs to be implemented step by step. Through in band measurement, the above problems can be effectively solved. The management and control system detects in band performance based on real business flow, provides real-time and high-precision network end-to-end performance visualization and hop by hop fault demarcation capability, and improves the efficiency of fault demarcation and location for performance degradation. In band performance detection has the characteristics of small maintenance of measurement task, real service quality index and rapid fault location; it can realize automatic identification of in band service flow, and automatically identify end-to-end path and service quality according to base station IP address and EPC / NGC IP address. In band performance data can be quickly reported to OMC system by using telemetry protocol, which provides data analysis basis for intelligent operation and maintenance.<BR>
