Greetings again. draft-cardenas-dff, "Depth-First Forwarding in Unreliable
Networks (DFF)", describes an experimental protocol that lets the network try
to heal routing problems with messages in the data plane (instead of in the
control plane). The protocol will change the routing of future packets in a way
very similar to routing changes do today.

The security considerations section seems complete well thought-out. Basically,
it says "content of redirected packets is out of scope, as is upper-layer
security", which seems fine. It discusses the main concerns, which is this
protocol making some denial-of-service attacks a bit easier, and does so fairly
completely.
