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.
