the TCP/UDP tunnels used to connecting up remote NDN nodes are viewed as (virtual) link layer, rather than transport layer.

Not sure I followed your way of thinking.
By its name, NDN focuses on how to fetch data by names, not how to keep connection up with a mobile node.
here is a pointer to
"A Survey of Mobility Support in Named Data Networking"
see if it might help answer your question
