Abstract
We introduce a natural distributed model for analyzing
the survivability of distributed networks and network rout-
ing schemes based on considering the effects of local con-
straints on network connectivity. We investigate the compu-
tational consequences of two fundamental interpretations
of the meaning of local constraints. We consider a full-
duplex model in which constraints are applied to edges of
a graph representing two-way communication links and a
half-duplex model in which constraints are applied to edges
representing one-way links. We show that the problem of
determining the survivability of a network under the full-
duplex model is NP-hard, even in the restricted case of sim-
