Soooooo, above my head, but, really important I think. I think, could easily be wrong, that it speaks to a more p2p Internet, not one that is so backbone dependent.

increase robustness, accessibility, and reliability of data transmission.
Recently, network coding has been proposed as a solution to provide agile and
cost efficient network protection against link failures, which does not require
data rerouting, or packet retransmission. To achieve this, separate paths have
to be provisioned to carry encoded packets, hence requiring either the addition
of extra links, or reserving some of the resources for this purpose. In this
paper, we propose network protection codes against a single link failure using
network coding, where a separate path using reserved links is not needed. In
this case portions of the link capacities are used to carry the encoded
packets.
