IntroductionThis paper presents the development stages of a model of a distributed system in which the primordial abstract elements are the process and the connection (link) between processes. This paper deals with the problem of communication between the processes within the distributed system, with the concept of message exchange between processes, and also presents the problem of distributed agreement. This paper presents the importance of two concepts: the logical time of a distributed system and the causal order of messages. All of these concepts are necessary to define a model of a distributed system in which some processes have the role of management of the operations carried out by other processes which only have an execution role. After presenting of the processes of the system components, there is an abstraction of the exchange of messages between the processes of the distributed system. In the next step, an abstract model of a distributed system is proposed and analyzed, in which there are modelled several worker-processes controlled by a manager-process, which runs on different

“…Service-oriented methodologies have been regarded as promising solutions for future distributed applications [1,18,8]. Meanwhile, because of the distributed and dynamic nature of web services, many researchers propose that quality of services (QoS) should be addressed for successfully building critical service oriented applications [14].…”

Web-service-related techniques have become popular to improve system integration and interaction. In distributed and dynamic environment, web services' availability has been regarded as one of the key properties for (critical) service-oriented applications. Quality of Service (QoS), including availability, has been regarded by IEEE as a userperceived property. However, based on our investigation of monitoring invocation records of real web services, existing availability metrics, which were proposed in traditional domains, have not addressed the "user-perceived" characteristics. Based on analyzing the limitations of the existing availability metrics, we propose a status-based userperceived service availability metric and a corresponding estimation approach. Experiments on monitoring and analyzing the invocation records of real services demonstrate that the new metric and the corresponding estimation approach could lead to a feasible estimation on web services' availability from the user side.

“…The Web services community has developed applicationlevel reliable messaging protocols built on top of SOAP and HTTP (Davis et al, 2008;Iwasa et al, 2004). These protocols are not client-transparent and do not address the key topics of message persistence and recovery from faults (Moser et al, 2007).…”

The Web is increasingly used for critical applications and services. We present a client-transparent mechanism, called CoRAL, that provides high reliability and availability for Web service. CoRAL provides fault tolerance even for requests being processed at the time of server failure. The scheme does not require deterministic servers and can thus handle dynamic content. CoRAL actively replicates the TCP connection state while maintaining logs of HTTP requests and replies. In the event of a primary server failure, active client connections fail over to a spare, where their processing continues seamlessly.We describe key aspects of the design and implementation as well as several performance optimizations.Measurements of system overhead, failover performance, and preliminary validation using fault injection are presented.
