Hi,
I was going through TIPC documentation and wanted someone to clarify
my understanding of connectionless reliable communication.
As mentioned in the documentation, when socket type 'SOCK_RDM' is
used, TIPC provides connectionless reliable communication. The only
difference I see between SOCK_RDM and SOCK_DGRAM is the setting ofsource
droppable bit. For SOCK_RDM, it is disabled. This bit only makes sure
that TIPC does not drop the messages when the source port is congested.
Now the question is, do receivers acknowledge a message by sending
an ack to the sender when the end points are using SOCK_RDM?
I also wanted to know if TIPC supports reliable multicast on
connectionless socket while using SOCK_RDM or SOCK_DGRAM socket. What I
mean here by reliability is that do receivers acknowledge the receipt of
a message by sending an ack to the sender?
Another question which came to me is that if SOCK_RDM uses
acknowledgments than what will happen if the acknowledgement for a
message is not received by the receiver. Till what time it keeps it in
its send queue and when it retransmits this message.
Thanks,
Bharat
