Abstract

一种基于PCIe的数据传输方法及装置，涉及通信技术领域。该方法包括：第一节点获得并发送第一TLP。交换节点接收到第一TLP，向第二节点发送第二TLP。第一TLP包括第一TLP头和第一负载，第二TLP包括第二TLP头和第一负载，第一、二TLP头用于指示第一负载的数据类型，第一负载的数据类型包括音频、图像、控制、数据流写、或安全中的至少一个。第二节点根据第一负载的数据类型，解析第一负载。这种技术方案使得第一节点和第二节点之间可以的通信可以无需通过PCIe系统中的根节点，而且第一节点和第二节点之间的通信可以只涉及PCIe接口，不涉及不同接口之间信息的转换，从而有助于降低在高速通信场景下通信的复杂度。
