Hi Arif

False and false.
NDN Protocol Design Principles
https://named-data.net/project/ndn-design-principles/ allow only one Data
packet in reply to each Interest. It isn't possible for a producer to send
multiple Data packets to one Interest.

You need a dataset synchronization protocol, such as *PSync PartialSync*,
for this use case.

Yours, Junxiao
