Port Task Groups [PTG]
Warning – PTG are not guaranteed!
- PTG notifications are generated when AS Router performs an optimization step for a port—that is, when there are multiple eligible task groups and Router must choose a “next task group plan” for that port.
- If no optimization is needed (for example, when there is only a single eligible task group and it is assigned immediately when the port is opened and
open_binis called), AS Router may assign that task group directly to the port without performing a PTG optimization step, and thus no PTG message is sent for that assignment.- Because of this design, integrations must not rely on PTG messages as a guaranteed pre‑announcement of every task group assignment. Some assignments will legitimately occur without any prior PTG notification.
