Giuseppe,

One Interest can only elicit one data. If you know that the data on the other side is segmented, you need to establish some kind of 
convention for segmenting, so that when the consumer receives the data, the data name that it received makes it clear that there are more 
segments.

E.g. if you send an interest for /ndn/experiment/images/waterfall, and the consumer gets a data back called 
/ndn/experiment/images/waterfall/s1, then it should be clear to the consumer to request s2, s3, ..., sN, until the last interest gets 
NACK'd. From there you could conclude that you have all the data, and then concatenate all of the contents to retrieve your image, for example.

At least, this is how it's done in NLSR to transfer large LSAs.
