Up to now Service Oriented Architectures and Event Driven Architectures have been considered as competing parties striving to conquer the crown of the standard paradigm for the implementation of complex distributed applications. Todays we are witnesses of large efforts to merge both paradigms and give birth to a new generation of middleware platforms that will inherit the best of both worlds. In this...
Peer-to-peer systems (P2P) have become a popular technique to architect decentralized systems. However, despite its popularity most P2P systems consist in simple applications such as file sharing or chat systems. The main reason is that more complex applications require levels of consistency that nowadays are not offered by P2P systems. In this paper, we explore how to provide consistency based on...
This paper introduces a novel architecture for implementing content-based pub/sub communications on top of structured overlay networks. This architecture overcomes some well-known limitations of existing infrastructures, i.e. lack of self-configuration and of adaptiveness to dynamic changes. This is achieved by devising a mediator stratum between the rich event subscription semantics of content-based...
The ticket-based concurrency control allows the management of indirect conflicts between multidatabase transactions without violating site autonomy and ensuring global serializability. In this paper, by using discrete event simulation models, we compare two global concurrency control algorithms: the Optimistic Ticket Method (OTM) and the Multidatabase Timestamp Mechanism (MTSM). Performance of those...
