Hello All,
I have 2 questions.
First,
I have added hopCount tag to the packet. But my questions is why these tags
have to be 64 bit log? I tried to use 16/32 bit long tags. I got
compilation issues.
I see the following tags are also defined as 64 bit long. ref -
https://github.com/named-data/ndn-cxx/blob/master/src/lp/tags.hpp
typedef SimpleTag<uint64_t, 10> IncomingFaceIdTag;
typedef SimpleTag<uint64_t, 11> NextHopFaceIdTag;
Second,
Also, is there a way I can calculate the interest packet overhead after
adding a new tag?
If I do following before and after adding the tags, would I get correct
result?
auto intSize = interest.wireEncode().size();
Ndn-dissect didn't work very well, I didn't get what I was looking for.
Some fields were missing.
