[Ndn-interest] Proposed deprecation: byte offset segmenting

Dear folks

NDN Naming Conventions revision 1 defines two segmenting markers: 0x00 and
0x00 is the segment number marker. Segments of a content are assigned
consecutive segment numbers.
It is commonly used in many applications, including ndnputchunks, NDNFS,
and PSync.

0xFB is the byte offset marker. Segments of a content are given this marker
followed by payload's byte offset within the content.
We are unaware of any application that adopts the 0xFB byte offset marker.
Moreover, unless using a manifest, the consumer cannot predict the byte
offset of every segment, and thus hinders the efficiency of content
retrieval because pipelining cannot be used.

Alex has promised to discontinue byte offset segmenting in NDN Naming
Conventions revision 2.
If anyone on this mailing list has an application that currently uses 0xFB
marker, please speak up within 5 days.

Yours, Junxiao
