Hi All,
I was trying to write an application in rdma . I understood that when a connection is established between remote endpoints, RDMA_CM_EVENT_ESTABLISHED event is generated in both server and client.
My question is Who will get RDMA_CM_EVENT_ESTABLISHED notification first, Server or client ? Is there any order to keep it strictly .
Can we set the connection is established if any of the side to get the events or should we need wait to get the RDMA_CM_EVENT_ESTABLISHED event in both side.
Thanks & Regards
Rafi KC

There is no guarantee which side will receive the event first.
The only restriction is that the side which initiates the first data transfer must wait until it sees the event before sending.
