Industrial Applications

1. High-Reliability Industrial Ring Network Integration

Utilizes ERPS ring protocols to construct robust industrial rings with up to 8 rings, ensuring network topology continuity in harsh environmental segments.

Problem Solved

Solves critical communication failure risks by delivering self-healing network recovery times of under 50ms upon physical link interruption.

2. Enterprise Multi-Subnet Layer 3 Routing

Deploys static and dynamic RIP v1/v2 routing protocols to route traffic between isolated IP subnets or VLANs directly at the switch level.

Problem Solved

Eliminates local inter-VLAN bottlenecking on external routers, improving local bandwidth and overall packet routing efficiency.
