Abstract

本申请公开了一种基于PCIe的数据传输方法及装置，可以使得PCIe系统中节点与节点之间的通信无需经过根复合体，例如端节点与端节点之间的通信，或者交换节点与交换节点之间的通信，或者交换节点与端节点之间的通信。该方法包括：第一节点将第一数据封装成第一TLP并向第二节点发送第一TLP，其中，第一TLP的TLP头包括第一字段，该第一字段用于指示第一数据的数据类型，该数据类型包括如下至少一项：图像类型、视频类型、控制类型、安全类型、SWRITE类型。本申请实施例中通过使用TLP头的第一字段指示传输数据所需的信息，例如数据类型，可以使得节点之间无需经过根复合体进行通信，从而降低PCIe系统内的通信复杂度。
