Abstract
Operator interviews and anecdotal evidence suggest that
an operator's ability to manage a network decreases as
the network becomes more complex. However, there is
currently no way to systematically quantify how com-
plex a network's design is nor how complexity may im-
pact network management activities. In this paper, we
develop a suite of complexity models that describe the
routing design and configuration of a network in a suc-
cinct fashion, abstracting away details of the underlying
configuration languages. Our models, and the complex-
ity metrics arising from them, capture the difficulty of
configuring control and data plane behaviors on routers.
They also measure the inherent complexity of the reach-
ability constraints that a network implements via its rout-
