SECMP0030 'Demand Management of DCC Systems'

Where network traffic approaches or exceeds the capacity of the DCC System, Users could experience fluctuations in system performance, extended round trip times or in extreme cases the system could fail.
This modification proposes to implement an enduring solution that protects the DCC System when aggregate demand cannot be satisfied simultaneously. This modification proposes establishing appropriate rules to enable the prioritisation of Service Requests and Service Responses across the DCC User Interface and the prioritisation by the DCC of Commands to be sent to Communications Hub Functions and Certificate Signing Request volumes in an equitable, fair and transparent way. Rules by which DCC will actively control Device Alert volumes should also be considered for inclusion in this modification process.

The Proposer therefore seeks to establish appropriate rules by which the DCC will actively control demand management across the DCC Systems, during periods where aggregate demand cannot be satisfied. This includes rules for:
– Service Requests and Service Responses across the DCC User Interface;
– prioritisation by the DCC of Commands sent to Communication Hub Functions; and
– Certificate Signing Request volumes.
The Proposer notes that rules by which the DCC will actively control Device Alert volumes should also be considered for inclusion, during the refinement of the modification.
