[Ndn-interest] ASF overhead

[Lan Wang (lanwang)]

Just want to mention that in order to verify the data, the consumer needs to retrieve the producer's key as well.  I am not sure if not knowing the identity of the producer is something that the architecture tries to achieve.

Thank you Ashlesh

Just another pragmatic question
Isn't the rationale behind CCN to decouple consumers and produces?

In another words, when a  consumer issues an interest, he does not know the identity of the producer

With HR when we issue an interest, we need to add its producer coordinates, doesn't this maneuver violate CCN principles

For the ASF strategy, what we did was to set the Nonce of ndnping to zero and count all non-zero Nonce as probing overhead for HR. Because there was no other way to distinguish between probe and ping as the interest is same.
You may also set the Nonce of the probe to some special value here instead of calling refreshNonce:

Just reposting from mini-ndn list as this might be better suited here.

Dear community

I was trying to evaluate overhead under various forwarding/ routing strategies in mini-ndn

with NLSR /best-route combination LSA/sync packets are used to compute overhead

with HR/ASF which packets are used to compute overhead, as ndndump files were analyzed no probing packets were found !

best regards
