Enterprise network architecture and management have followed the
Internet's design principles despite different requirements and char-
acteristics: enterprise hosts are administered by a single authority,
which intrinsically assigns different values to traffic from different
business applications.
We advocate a new approach where hosts are no longer relegated
to the network's periphery, but actively participate in network-related
decisions. To enable host participation, network information, such
as dynamic network topology and per-link characteristics and costs,
is exposed to the hosts, and network administrators specify condi-
tions on the propagated network information that trigger actions to
be performed while a condition holds. The combination of a condi-
tion and its actions embodies the concept of the network exception
