what happens when RoCE is run over lossy L2?

dear all , what happens if iSER is run on a lossy L2 link ?

This should answer your open questions: RoCE v2 Considerations https://community.mellanox.com/s/article/roce-v2-considerations

Dear Yairi, not that i am pondering over running it over lossy. I am interested to know

it theoretically.

I wouldn’t recommend.

one of the more basic prerequisites for RoCE and other RDMA applications (like iSER) is a reliable connection.


Dear Yairi

The referred article does answer my query. thanks.

"An underlying lossless Ethernet network is required for RoCE traffic only in order to avoid systematic

packet drops resulting from resource contention within network switches and adapters."
