Abstract: This disclosure discloses an address translation method, apparatus, and system. The method includes: receiving, by a first address translation unit (ATU), an access request sent by a first virtual machine (VM), where the access request carries a first address and parameter information of the first address, and the parameter information of the first address includes an identifier of a target virtual function (VF); determining, by the first ATU, a matching relationship based on the parameter information of the first address and VF range description information in an address mapping table; and when an identifier of a target VF and the VF range description information are successfully matched, translating, by the first ATU, the first address into a second address based on the address mapping table.

Abstract: A data stream and data packet transmission method and device are described, relating to the field of interface data transmission technologies. The method includes: a home end detects whether data to be transmitted is a data stream or a data packet; when it is detected that the data stream and the data packet exist simultaneously, the data stream is preferentially transmitted; and upon completion of transmission of the data stream, then the data packet is transmitted. According to the embodiments of the disclosure, when the data stream and the data packet exist simultaneously, high efficiency transmission of the data stream may be achieved with no need of extra external time for scheduling operations, effectiveness of transmission of the data stream is enhanced, and data transmission efficiency through the interface is improved.
