Petrochemical Central Control Layer-3 Backbone

Central control L3 cores interconnect units and utilities with 10G-class bandwidth for centralized monitoring.

1. Scenario

Central control must route-isolate units and peer with historians, video, and group networks.

2. Challenges

Security zones with diodes/firewalls; core redundancy; complex routing.

3. Architecture

PH-4M32P-M core; unit/tank 24GE aggregation; multi-SFP rings; 10G to server farms.
