A data transmission method and an apparatus are provided. The method includes: when determining that a first data stream satisfies a transmission optimization enabling condition, a first transmitting end TEsends a transmission optimization enabling notification to a first receiving end RE, where the transmission optimization enabling notification is used to indicate the REto skip sending, to the TE, an acknowledgment packet used to acknowledge that a data packet of the first data stream is already received by the RE. The TEreceives a data packet Datain a second protocol format from the TE. The TEsends a data packet Data1 in a first protocol format to the RE. The TEreceives an acknowledgment frame Ack1 in the first protocol format from the RE. The TEconstructs an acknowledgment packet Ackin the second protocol format based on the Ack1, and sends it to the TE
