Hi Koojana,

It's true that MSF works with RPL closely. And it's mainly designed for
upstream traffic.

As you mentioned, MSF could be extended by having autonomous cell to any
potential neighbors that the node intend to have packet exchanged with.
The concept of parent/upstream node could be replaced by the nexthop of the
routing protocols, I think.
