I know about cumulative and selective acknowledgements TCP protocol offers.

Do you know any other protocols (apart from TCP), that support cumulative acknowledgements?

    There may be several that are proprietary and never see the light of day. Why do you ask?

Trivial File Transfer Protocol (TFTP) running over UDP/69 also includes a built-in Acknowledgement system which is cumulative over the course of a file transfer.

Adding one:

IPsec includes a Sequence Number in the ESP/AH header. That can also be considered a cumulative acknowledgement. Although not in the strict sense that TCP or TFTP use it.

One such protocol is OSPF, which uses a Database Description Sequence Number to keep track of database updates.

I'm sure there are others.
