A network management framework for multi-layered network survivability: an overview

We consider an interconnected network environment where one network can act as a 'provider' or 'service' network to the 'user' network or a collection of 'user' networks. In such an environment, a major failure in a provider network can affect the user networks. Very often, failure management is addressed in each individual network domain independently. We present an overview of a loosely-coupled network management framework through the development of a multi-layered network manager of managers concept for correlated management, for failure cases that can not be addressed by each component network individually.
