Network connection over PCIE

I want to eatablish the network connection over PCIE,however it seems that l could establish a network connection without enabling the Endpoint (EP) mode. I’m confused about the differences between establishing a network connection by enabling the EP mode of the Jetson NX and directly establishing a network connection.

我用中文說明可能比較清楚一點
請問你現在到底是要做什麼事情? 整個comment看下來其實聽不太懂你到底要拿PCIe做什麼.
你是買了一張網卡要來用嗎? 還是你也聽不懂我在說什麼?

PCIe Endpoint Mode — Jetson Linux Developer Guide documentation (nvidia.com).我将NX和一台服务器相连,想用PCIE的End point 模式传输数据,发现内存只有128k太少,我看到End point教程里可以通过PCIE建立以太网,但无论是否启动End point模式都可以建立以太网连接,我想询问启动了EP模式的话,PCIE通道会起到一个网口的作用?

請問你的 “无论是否启动End point模式都可以建立以太网连接” 這句話到底是什麼意思?
是指說你用其他的方式進行連線嗎?

如果你只是想要兩台機器能連線傳輸的話, 那說實話你不用PCIe endpoint.

Yes, there is a network cable connected between the network ports of the two machines. So can PCIe cables actually replace Ethernet cables?是的,两台机器的网口之间连接了网线。所以事实上PCIE线可以替代网线吗?

對 PCIe endpiont就是多提供你一個方式可以讓PCIe RP/EP進行傳輸.

在這狀況下跟ethernet是沒有關聯的. 你也不是拿網路線在連.

最后确认一下:教程里提到通过PCIE建立网络连接,那我不连接网线,连接PCIE线就可以建立网络连接是吗。ust to confirm one last thing: The tutorial mentions establishing a network connection via PCIe. So, does it mean that I can establish a network connection by connecting the PCIe cable instead of the network cable?

是的
但我們的PCIe endpoint只有在Jetson -Jetson的連結上驗證過. x86 host PC的driver不一定能直接使用

谢谢您的解答,我没有疑惑了。Thank you for your answer, I have no further doubts.
