1. A Peripheral Component Interconnect Express (PCIe)-based data transmission method, wherein the PCIe-based data transmission method comprises:
obtaining, by a first node, a transaction layer packet (TLP) comprising data, a type field, and at least one reserved bit, wherein the type field and the at least one reserved bit indicate a first parameter set, and wherein the first parameter set comprises:
a data type of the data;
a pixel quantization depth when the data type indicates image data;
a quantization depth when the data type indicates audio data;
interface information when the data type indicates control-type information;
a message type when the data type indicates security data; and
an alignment manner when the data type indicates SWRITE data; and
sending, to a second node, the TLP.
