Recovery.

Your examiner asks how fast you recover, and for the last test. We write into your requirement: we test the move for real, and name who can order it before the cause is known.

  • What we check before you buy: who can approve a change, and the record of the last three approvals.
  • Our design: the pilot VLAN moved, rolled back and moved again in window 1, with at most 3 seconds of loss per gateway cutover.¹⁶
