A Framework for Dynamic Reconfiguration of Distributed Programs

Annotation: Inspired by Kramer and Magee's reconfiguration model in Conic, this work adapts that model to the Polylith distributed environment (supports general message-passing, not just RPC). Reconfigurations can change module implementations, application structure (e.g. add and remove modules), and application geometry (e.g. physical location of modules). This work extends the Conic work by adding support for capturing and restoring process state via an intermediate abstract representation [herlihy82value]. Reconfiguring modules must be quiescent; messages received during the reconfiguration are buffered and are used to initialize the replacement module.
