The primary advantage of the distributed Unified ICM option is the redundancy gained from splitting the
Unified ICM Central Controller between two redundant sites.
Best Practices
Unified ICM Central Controllers (Routers and Loggers) must have an isolated network path or link
to carry the private communication between the two redundant sites. In a non-distributed Unified
ICM model, the private traffic usually traverses an Ethernet crossover cable or LAN connected
directly between the side A and side B Unified ICM Central Controller components. In the
distributed Unified ICM model, the private communication between the A and B Unified ICM
components must travel across a dedicated link with at least as much bandwidth as a T1 line.
