Advantages
The primary advantage of the distributed Unified ICM option is the redundancy gained from splitting
the Unified ICM Central Controller between two redundant sites.
the Unified ICM Central Controller between two redundant sites.
Best Practices
•
Unified ICM Central Controllers (Routers and Loggers) should have an separate 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 should travel across a dedicated link with at least as much bandwidth as a T1 line.
