Confusion regarding RDMA read behavior during retransmission

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Spec says:
The PSN of the retried RDMA READ request need not be the same as the
PSN of the original RDMA READ request. Any retried request must
correspond exactly to a subset of the original RDMA READ request in
such a manner that all potential duplicate response packets must have
identical payload data and PSNs regardless of whether it is a response
to the original request or a retried request.

It seems that a retransmitted READ must return identical data to the original.

But consider this scenario
a READ followed by WRITE followed by the original(retransmitted) READ.
What is the expected response in this case? I tried this and it
returns the latest value which is what I would expect.
My question is why do we not return the original data?


Thanks and Regards,
Abhishek
