[Nfd-dev] a question about PIT entry

[Lan Wang (lanwang)]

Hi,

I have a question about how to keep a PIT entry in a particular situation.  Suppose there are two nodes:

a — b

1) a and b both send the same interests (same name) to each other.
2) a responds to b’s interest with a data packet.  In the current PIT implementation, it will remove both a and b's PIT entry for this interest.

We hope that a’s data packet would not erase the PIT entry in a and b completely (only remove the necessary in and out records) so that b can still respond to a’s interest.

This is inspired by a partialsync implementation issue.  Is there any way to achieve this result?
