[Ndn-interest] NDNVideo: Available over NFD?

[Alex Afanasyev]

In my opinion, cut-through forwarding of segments is a possible optimization of hop-by-hop fragmentation which can be applied only for some of the data packets: only those that are not requested with security constraints (e.g., when neither interest name doesn’t contain implicit digest nor interest doesn’t include data packet signature constraint).  Also, cut-through optimization is meaningful when router connect networks with similar (same) MTU characteristics.
