when it is deployed at the border of the network. It has been when it is deployed at the border of the network. It has been
shown that cache hit ratio grows logarithmically with the amount shown that cache hit ratio grows logarithmically with the amount
of users [cache]. Taking this into account, when ITRs are of users [cache]. Taking this into account, when ITRs are
deployed closer to the host the effectiveness of the mapping cache deployed closer to the host the effectiveness of the mapping cache
may be lower (i.e., the miss ratio is higher). Another may be lower (i.e., the miss ratio is higher). Another
consequence of this is that the site may transmit a higher amount consequence of this is that the site may transmit a higher amount
of Map-Requests, increasing the load on the distributed mapping of Map-Requests, increasing the load on the distributed mapping
database. To lower the impact, the site could use a local caching database.
