[Nfd-dev] Help needed with debugging duplicate Nonce

[Junxiao Shi]

Hi Lan

When forwarder receives a Nack from face A, it records on the PIT out-record of face A that a Nack has been received, and triggers the strategy. In case Data comes from face A in the future, this Data would still be accepted.
When strategy instructs forwarder to send a Nack to face B, it removes the PIT in-record of face B. In case the PIT entry is later satisfied by Data, face B would not receive a copy of this Data.

To make ChronoSync work in the general case, we should design for the situation where /localhop is not used, even if there might be a workaround with /localhop.

Yours, Junxiao
