A role model to cope with the complexity of network configuration

INOC 2007, Spa, Belgium, April 22-25, 2007.
Abstract: In this paper, we propose a role model to cope with the complexity of network configuration. Roles associate policy requirements as well as configuration templates with nodes in the network. One goal is to remove redundancy in configuration data to avoid inconsistent changes and diverging setup of similar devices. The other goal is to ensure that network policies are respected by the configuration.
This role model is embedded into the project Verified Network Configuration (Verinec). Together with
the Verinec XML network model, roles provide a powerful instrument to configure large networks.
