Dear Boubakr,

As far as Data is concerned, it is divided into Chunks.... Each Chunk can
have its ID.

Now coming to the point that is there an Interest for every chunk !!! It
depends on your application and forwarding strategy. Some protocols have
been proposed with the keyword "Long Lived Interests". You may wanna go
through it.

Normally, it is in the practice that the consumer can send an Interest for
every Chunk as we never know that the missing chunk may be cached by
another node (that shows up after the first Interest was sent out) in
Mobile Ad Hoc environment specifically.

Having said that, comparing to TCP session would be ambitious anyway.
