SmartFrog meets LCFG: Autonomous Reconfiguration with Central Policy Control
Paul Anderson, University of Edinburgh; Patrick Goldsack, HP Research Laboratories; Jim Paterson, University of Edinburgh
Typical large infrastructures are currently configured from the
information in a central configuration repository. As infrastructures
get larger and more complex, some degree of autonomous reconfiguration
is essential, so that certain configuration changes can be made
without the overhead of feeding the changes back via the central
repository. However, it must be possible to dictate a central policy
for these autonomous changes, and to use different mechanisms for
different aspects of the configuration.
This paper describes a framework which can be used to configure
different aspects of a system using different methods, including
explicit configuration, service location, and various other autonomous
techniques. The proven LCFG tool is used for explicit configuration
and to provide a wide range of configuration components. The dynamic
elements are provided by the SmartFrog framework.
