Yes, this is an alternative to what is described in the paper I referred to. It is an interesting idea actually. > None of this allows you to fail over a connection. Correct. Another question is whether session failover is a requirement. This may depend on the type of network we look at. In some networks, if failovers happen infrequently, a simple solution that causes some sessions to break in the event of a failover may actually be acceptable. All this requires extra intelligence in applications, of course: for NAT traversal, and potentially for automated session re-establishment. But one may argue that applications require this functionality already today. - Christian _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
