Another major aspect:
As with this model, each node (router) gets assigned a
longitude/latitude-pair, this info is also available for each OSPF intra-domain
node. A combined network topology should be envisioned:
one part comes from the hierarchical interdomain network view, the other
part from the OSPF-topology.
Example: Assumed, the AOL network runs routers both in Munich, Germany, as
well as in Sausolito, US.
If the packet's destination is somewhere in Sausolito (not necessarily an
AOL customer), it may take its route inside the AOL-network, being guided
by the geo-info rather than (although available) by prefix infos - and NOT by
the viewed Los Angeles node from the hierarchical interdomain topology
part !
I am convined that many services as well as TE capabilities can and
will be created in the future based on such a combined topology view.
