Abstract: Embodiments are directed to a bus bridge transfer protocol in a bus bridge system that uses a tag based transfer protocol to identify transactions. The bus bridge may receive a protocol request from an initiator that does not use the tag based transfer protocol. A designated tag consistent with the tag based transfer protocol may be assigned for use in requests from the non-tag conforming initiator. When receiving a request from the non-tag conforming initiator, an initiator flag is set to indicate that the request is from the non-tag conforming initiator and that the response should be forwarded to the non-tag conforming initiator. When receiving a request from a tag conforming initiator, if the request includes the designated tag, the initiator flag is set to indicate that the response should be forwarded to and that the designated tag is being used in a request from the tag conforming initiator.
