2.6.15.3 Internal Resource Management

DSR utilizes proven platform infrastructure to monitor, alarm, and manage the resources used by internal message queues and protocol data unit (PDU) buffer pools to prevent loss of critical events and monitor and manage PDU pool exhaustion.

Message Queue Management

• Enforces a maximum queue depth for non-critical events; non-critical events are never allowed to overflow a queue’s maximum capacity.
• The system attempts to always queue critical events even when the queue’s maximum capacity is reached.
• Measurements and informational alarms are maintained for discards of all events.

PDU Buffer Pool Management

• Similar to message queues, the DSR monitors the size of each PDU Buffer Pool, alarms when the utilization crosses configured thresholds, and discards messages when the PDU Buffer pool is exhausted.
• Measurements are maintained for all discards.
