Hi all,
I am pretty new to this working group.
I have a question regarding forward progress described in the RFC 2461.
At what instance of a connection , TCP or anyother connection oriented protocol
will inform the IP about a forward in progress?.
RFC 2461 says
" When possible, upper-layer protocols provide a positive confirmation that
a connection is making "forward progress", that is, previously sent data is
known to have been delivered correctly
(e.g., new acknowledgments were received recently). "
What time should IP expect this hints from the upper layer protocol ?
Will it be with all the packets sent from the upper layer or
do we have any mechanism like a setsockopt () so that the upper layer can
inform the IP about the forward progress? Please help.
Thank You in advance
