RE: discussion on fast notification work

Alia,

The problem is clear: how to do fast fail-over in IP and LDP with full failure coverage in arbitrary network topologies. Several other ongoing proposals are targeting the same problem (just to mention Not-Via or MRT). So, I think there is consensus that the problem needs solving.

Per-hop authentication should minimise the security implications considerably. We have been working on a prototype doing this with SHA256 and we are adding this to the draft now.

Cheers,
András
