What is the issue?
This modification proposes to enable the implementation of a traffic management solution to protect the DCC system and Service Users against alert storms originating from a single device.
What is the solution?
The proposed solution is to provide Alert Storm protection through a DCC designed mechanism which will count the number of Alerts originating from a specific Device within a defined time window. If the Device sends the same Alert above a pre-determined threshold value, the mechanism will discard excess Alerts from the Device and only forward one copy of that Alert in a designated period agreed by the DCC on to the intended Users.
