Abstract: Transmission control checking circuitry adds control check data to a transaction response which is received at a transaction master and compared with expected data at the transaction master. The expected data having control check data may be a unique transaction identifier. The transaction master generated the unique transaction identifier when it generated the transaction request and will check that the transaction responses include that unique transaction identifier. In this way, errors in the control of transmission of transactions (e.g., misrouting) may be detected.

Abstract translation: 传输控制检查电路将控制检查数据添加到事务响应中，该事务响应在事务主机处接收并与交易主机处的预期数据进行比较。 具有控制检查数据的预期数据可以是唯一的事务标识符。 交易主机在生成事务请求时生成唯一的事务标识符，并检查事务响应是否包含该唯一事务标识符。 以这种方式，可以检测到事务传输控制中的错误（例如错误路由）。
