Document 8800 octet limit for data packet size
Added by Jeff Burke over 10 years ago.
Updated about 10 years ago.
Description
I cannot find mention of the practical 8800 octet limit (or MAX_NDN_PACKET_SIZE) for data packets in either the packet format spec, NFD, or NDN-CXX documentation.
Can this be documented? This would be useful to libraries that are performing segmentation based on this limit, and provides a spec upon which to base the behavior of NDN-CCL.

At 20140114 meeting, Van said:
mechanism does not have to embody policy. mechanism doesn't care, just grabs bits until end marker. policy decision imposed when it arrives.
The 8800-octet limit is a practical limit which is a kind of "policy", so it cannot be mentioned in NDN-TLV spec.
ndn-cxx documentation already contains MAX_NDN_PACKET_SIZE constant in Doxygen.
There is no description for this constant, because the constant name is sufficient for its meaning.
MAX_NDN_PACKET_SIZE limit is imposed on all packet types, not just Data.
Yes, I agree that it doesn't need to be in the spec, but the current location is a little obscure for someone not familiar with the library or that knows where to look - and it is relevant to many. Perhaps it could be mentioned in the FAQ or another part of the NFD / ndn-cxx documentation.
- Related to Task #2099: Move definition of MAX_NDN_PACKET_SIZE added
- Target version set to v0.3
20141031 conference call decides that this can be documented in ndn-cxx Application Developer Guide.

7 days passed since I commit the documentation. I assume it's done.
