Toni, all who responded are right: A locator identifies a node and not a path. What you have in mind is source routing, which is used in MPLS. We should not fall back to that. But what makes sense is having directives which support hop-by-hop routing in order to pursue consistently some particular (among multiple ones) path towards the destination. The internet is spanning the globe. You can really get to India while going West !!! But confusion about which direction is to be taken must be avoided during forwarding. Furthermore I would also be much in favor of enabling the conveyance of via-nodes, particularly in case of detours. A lot of interesting work is still waiting to be done as to build a future-prone network layer, where -wrt a given destination- all adjacent links of any transit router are potential next hops (except those which lead into dead end).

The locator is formed as sequence of neighor IDs, each among the neighbors of the node with the preceding ID. This locator resembles a path but each component of it is a node-local ID, not a universal location name. So, the locator is to be used as hop-by-hop location pointer. > > PS: IEN-1 is only available in PDF, not in text/plain. > Please see this URL: > http://postel.org/ien/pdf/ien001.pdf > _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
