Claim 17:
18. A computer-implemented method, comprising:
receiving, by a write re-order buffer (WROB) and from a requester device, a first write transaction followed by a second write transaction, wherein the first write transaction and the second write transaction are to be executed by one or more completer devices that are coupled to the requester device through an interconnect fabric;
assigning, by one or more processing units of the WROB, a first group identifier (ID) to the first write transaction;
determining, by the one or more processing units, that the second write transaction depends on the first write transaction;
assigning, by the one or more processing units, the first group ID to the second write transaction in response to determining that the second write transaction depends on the first write transaction; and
forwarding, by the WROB, the first write transaction and the second write transaction to the interconnect fabric for routing, wherein the interconnect fabric is configured to route transactions such that transactions assigned to a same group ID are executed in order.
