Understanding Performance Measurement in Huawei CloudWAN
Huawei CloudWAN enables intelligent traffic management, real-time network monitoring, and automated operations.
???? Traditional Performance Monitoring Methods
TWAMP (Two-Way Active Measurement Protocol) → Measures latency and jitter by injecting test traffic.
Telemetry → Provides real-time network visibility, but does not measure actual service traffic performance.
BGP FlowSpec → Used for DDoS mitigation, not performance measurement.
???? iFIT (In-situ Flow Information Telemetry)✅ iFIT is a next-generation performance monitoring technology that measures:
Real service traffic performance (latency, jitter, packet loss) in real time.
Packet forwarding behavior at each hop without injecting synthetic traffic.
Path delay and service degradation detection.
Why is Answer D Correct?
✅ iFIT provides real-time network performance monitoring based on actual service traffic.✅ Unlike TWAMP, iFIT does not require probe packets, reducing overhead.
Real-World Application:
5G Transport Networks: Ensures low-latency paths for ultra-reliable services.
CloudWAN Optimization: Detects network congestion without affecting user traffic.
