SECMP0062 Northbound Application Traffic Management - Alert Storm Protection

Proposer Graeme Liggett
Lead Analyst Harry Jones
Date raised 27/09/2018
Implementation date Part 1 June 2020 SEC Release - Part 2 Nov 2020
Latest update Part 1 of the solution was implemented on 6 May 2020 (June 2020 SEC Release). Part 2 will be implemented on 5 November 2020 (November 2020 SEC Release).

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.
