A Flexible Event-Driven Architecture for Peer-to-Peer Based Applications

Over the last decade, we have seen an increasing interest in the event-driven architecture (EDA) approach. EDA allows the transmission of events among loosely coupled and highly-distributed software components, which is totally adequate to peer-to-peer based applications mainly considering features of scalability and flexibility. In this paper, we present the initial steps towards the design and implementation of a peer-to-peer based EDA, which is intended to reduce the coupling between application layers, and achieve a better distribution of responsibilities between the architecture elements and the environment. Our flexible EDA framework, proposed in this work, inherits important features such as scalability, decentralization and fault-tolerance from the peer-to-peer domain. For a preliminary evaluation of our approach, two experiments using the EDA framework were conducted in different domain applications.
