SECMP0067 Service Request Traffic Management

Proposer Graeme Liggett
Lead Analyst Harry Jones
Date raised 30/11/2018
StageRefinement Process
Implementation date Targeted for November 2020 SEC Release
Latest update The Authority decided to send back SECMP0067 for further work and to be resubmitted.

What is the issue?

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.

What is the solution?

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.
