As networks grow in size and complexity, network management has
become an increasingly challenging task. We argue that ``bolting
on'' network-management functions to the existing architecture is
the wrong approach. Instead, networks should be designed with
management in mind from the beginning. We focus on two important
aspects of network management: tomography and optimization. We
present principles with illustrative examples of recent research
that pinpoint why network management is difficult and show how
changes to existing protocols and architectures can lead to
manageable networks. We also discuss the trade-offs between making
network management easier and the overhead these changes impose.
