The hosts do not have visibility of the path. They only know the other end is sending them packets. And you get this as well from a router-based approach.
Dino, in both host-based and network based solutions, the availability status of a path needs to be measured through the delivery, or the lack of delivery, of packets. My point is that the faithfulness of such measurements differs between host-based and network-based solutions: For host-based solutions, delivery of a packet is reliable evidence that a path is available because the packet has traveled the entire end-to-end path. For network-based solutions, delivery of a packet is less reliable evidence, because it doesn't account for path failures downstream of the router receiving the packet. - Christian _______________________________________________ rrg mailing list [email protected] https://www.irtf.org/mailman/listinfo/rrg
