1. A peripheral component interconnect express (PCIe)-based data transmission method, comprising:
encapsulating, by a first node, data into a transaction layer packet (TLP), wherein the TLP comprises a packet header and an extension header, the packet header comprises a first field and a second field, wherein the first field comprises a type field and the second field comprises a T9 field, the type field and the T9 field are jointly encoded to indicate a data type of the data, and the extension header is used to indicate at least one encapsulation parameter corresponding to the data type, the data type comprises at least one of an image, audio, control information, stream write (SWRITE), or security, and the at least one encapsulation parameter represents at least one attribute of the data type; and
sending, by the first node, the TLP to a second node.
