The specification of the ALTO protocol uses map based approaches
assuming that the information provided is static for a longer period
of time. But in some cases network operators reallocate IP subnets
from time to time which in turn changes the mapping partitions[I-
D.ietf-alto-deployments]. Since the ALTO clients are unaware of the
map information changes, clients need to query the servers for every
service request and many such requests are redundant because the
information was not changed. The purpose of this memo is to provide
two mechanisms which will help the ALTO clients to be informed of the
map information changes. a) ALTO clients cache the map information
and the servers provide the expiration time for invalidation. b) ALTO
clients can subscribe for event notifications from the server
