One fundamental idea of service-oriented computing is that applications should be developed by composing already available services. Due to the long running nature of service interactions, a main challenge in service composition is ensuring correctness of failure recovery. In this paper, we use a process calculus suitable for modelling long running transactions with a recovery mechanism based o...

In this paper we propose a priority sch,eme for reconnection of virtual circuits (VCs) in ATM networks that have been disrupted b y a failure. ATM networks offer several service categories each designed to hand le applications with specific trafic characteristics. A failure typically results in a large number of disrupted connections in each category, a l l of which must be restored simultaneou...

We present a new failure detector implementation. This implementation, a variant of the heartbeat failure detector, is both adaptable and designed for scalability. Its first specificity lies in the fact that it is designed as a shared service among several applications by way of an adaptation layer. This layer adapts the quality of service according to application needs. The second specificity ...
