SECMP0067 'Service Request Traffic Management'

The DCC System has a finite capacity. Even with communication with Service Users to meet forecasted demand and making the most efficient use of the System’s current capacity, it may be unable to cover accidental or unanticipated large bursts of Service Requests. This current mechanism therefore doesn’t act in favour of the Service Users who have not been responsible for the overload and penalises them equally.

The proposed solution is to define a maximum system capacity, operating threshold and appropriate Service User allocations. When the DCC System reaches this operating threshold, traffic management of the Service Requests will become active. Service Users who are exceeding their allocation will then have their requests throttled down to either their stated allocation or the operating threshold (whichever is greater). This should prevent Service Users crowding out others who are using the System by adhering to the allocations.
