The present application is applicable to the field of data transmissions. Disclosed are a data transmission method and a gateway device. The method comprises: a first gateway device acquiring a RoCEv2 message to be sent to a second gateway device, generating a target request, and sending the target request to a network controller, wherein the two gateway devices transmit data on the basis of a SRv6 network; the network controller obtaining a path calculation result on the basis of the target request, and returning the path calculation result to the first gateway device, wherein the path calculation result comprises a network path between the two gateway devices, and reserved network resources; the first gateway device expanding the RoCEv2 message according to the path calculation result, wherein the expanded RoCEv2 message carries a first identifier (representing each network node in a network path) and a second identifier (representing RDMA data); and the network controller guaranteeing a bandwidth on the ba
