Inter-system connectivity resilience

To ensure inter-system connectivity resilience in the case of failure or loss of communication, the Optical Transport Manager provides the following:

• Buffering of events being sent between components of Optical Transport Manager

• Ability to retrieve northbound alarms that were held after a communications failure

• Ability to retrieve active southbound alarms after connection with an EMS is interrupted

• Ability to switch to a peer EMS instance in the case of failure

• Rediscovery of devices after failure of EMS/device communication
