Structuring adaptive replicated systems with design patterns and aspects

Abstract

The construction of adaptive replicated systems, in which the replication control protocols can be replaced at runtime, requires to face with complex structural concerns that include: (i) the integration of replication control protocols with the application code, (ii) the the interchangeability of protocol variants, (iii) the observation and handling of events in a distributed system, and (iv) the consistency of the replication control mechanism. In this paper, we show a way to tackle that complexity with the help of Design Patterns and Aspect Oriented Programming (AOP).
