Description

As mentioned in PR 150, we have implemented one way of warning users when TPs arrive "too late" at the tp_datalinkhandler, and therefore are not sent downstream to the Trigger.

However, as discussed at the 06-Dec-2023 Core Software meeting, it would be great to investigate ways to handle the situation differently. For example, maybe there is a way to never send out TPSets until all expected TPs arrive.

Research direction

Start by reading PR 150 and the discussion from the 06-Dec-2023 Core Software meeting, then inspect the tp_datalinkhandler behavior described there. Compare ways to handle late-arriving TPs, including waiting for expected TPs before sending TPSets, and document a concrete recommended approach and its effects on downstream Trigger delivery.
