Abstract: 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 TE1 sends a transmission optimization enabling notification to a first receiving end RE1, where the transmission optimization enabling notification is used to indicate the RE1 to skip sending, to the TE1, an acknowledgment packet used to acknowledge that a data packet of the first data stream is already received by the RE2. The TE1 receives a data packet Data2 in a second protocol format from the TE2. The TE1 sends a data packet Data1 in a first protocol format to the RE1. The TE1 receives an acknowledgment frame Ack1 in the first protocol format from the RE1. The TE1 constructs an acknowledgment packet Ack2 in the second protocol format based on the Ack1, and sends it to the TE2.
