Communication Topology Network and Switching Test Solution

📅Apr 8, 2026
Brief：The Communication Topology Network and Switching Test Solution provides communication topology network design and switching test solutions, ensuring voice, messaging, and business access remain continuously available under link/node failures. (1) Communication Topology: Two sites are interconnected via encrypted tunnels, with core business and media traffic classified by QoS; core services, databases, recording, and transcription are deployed in separate zones, with redundancy for key nodes and links. (2) Automatic Switching Mechanism: Link quality monitoring (packet loss/latency/jitter thresholds) + BFD fast detection triggers switching; post-switch automatic reversion policy and alarm linkage ensure switching time <1s (subject to on-site test report). (3) Switching Test Solution: Multi-scenario fault drills are completed before go-live (primary link interruption, primary link high packet loss, media node failure, database master-slave switching, etc.), recording "trigger condition—switching duration—business impact—recovery result" to form the "Link Switching Test Report.
