Conventional design focuses the components, but the properties of the system depend critically on the character of the interactions. Although software designers have good informal abstractions for these interactions, these abstractions are poorly supported by the available languages and tools. As a result, the choice of interaction is often defaulted or made implicitly rather than deliberately chosen. Further, interactions are usually programmed in terms of underlying mechanisms rather than the designers natural abstractions. UniCon supports a rich selection of abstractions for the connectors that mediate interactions among components. Connector implementation presents special challenges. The \"compiler\" must produce and integrate not only the object code for components, but also a variety of other run-time products. The definition of a connector requires many connector-specific kinds of information in the compiler, graphical editor, and associated tools. Extending the set of connectors supported by UniCon requires this information to be provided by the connector designer and automatically integrated in the compiler. The paper describes the role of connector abstractions in software design, the connector abstractions currently supported by UniCon, and implementation issues associated with supporting an open-ended collection of connectors.","PeriodicalId":302050,"journal":{"name":"Proceedings of International Conference on Configurable Distributed Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128859885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Little","doi":"10.1109/CDS.1996.509355","DOIUrl":"https://doi.org/10.1109/CDS.1996.509355","url":null,"abstract":"Software systems are typically composed of numerous components, each of which is responsible for a different function. Different implementations of a component may be possible, with each implementation tailored for a specific set of applications or environments. Being able to reconfigure software systems to make use of these different implementations with the minimum of effect on existing users and applications is desirable. Configurable software systems are also important for a number of other reasons: additional components or modifications to those currently available, may be required. For example, new versions of software components may be necessary due to the discovery of design flaws in a component; a RPC which provider unreliable message delivery may be suitable for an application in a local area network, but if the application is to be used in a wide area network, a different RPC implementation, which guarantees message delivery, may be necessary. Therefore, software is often required to be configurable, enabling modifications to occur with minimal effect on existing users. To allow this configurability, components should only be available through interfaces that are clearly separated from their implementations, allowing users to be isolated from any implementation changes. Object-oriented programming techniques offer a good basis upon which this separation can be provided. This paper describes a model for constructing configurable software based upon this separation, and illustrates this with a software development system.","PeriodicalId":302050,"journal":{"name":"Proceedings of International Conference on Configurable Distributed Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124998873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of the reconfiguration is to repair software faults and to update software functionality. This should be done on-the-fly without decreasing the system's availability which means during the on-going operation of the system. The developed approach is based on available distributed operating system technology (Chorus) and on a widely used family of programming languages (C/C++). It does not require changes in the operating system nor in the development system. All needed adaptations are done in the application. However, it was our goal to keep the development of the application functionality separated from the creation of the replaceability. An application is made replaceable through some systematic changes which can be done automatically. Some additional effort is still needed. This paper describes the mechanisms developed for that purpose. As a reconfiguration unit we have chosen a Chorus actor which is a kind of a multi-threaded process. We describe how to make such a process replaceable. Finally, we give some performance figures to show the efficiency of the implemented algorithms.","PeriodicalId":302050,"journal":{"name":"Proceedings of International Conference on Configurable Distributed Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129597764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A customizable operating system is one that can adapt to some particular circumstance to gain some functional or performance benefits. Microkernels have attempted to address this problem, but suffer performance degradation due to the cost of inter-process protection barriers. Commercial operating systems that can efficiently adapt themselves to changing circumstances have failed to appear, in part due to the difficulty of providing an interface that is efficient to invoke, provides a protection barrier, and can be dynamically reconfigured. Providing such a safe, efficient, and dynamic interface in a concurrent operating system requires an effective concurrency control mechanism to prevent conflicts between system components proposing to execute specialized components, and those components responsible for dynamically replacing specialized components. We outline our basic approach to specialization of operating systems, and detail our dynamic replacement mechanism and its concurrency control features.","PeriodicalId":302050,"journal":{"name":"Proceedings of International Conference on Configurable Distributed Systems","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123952657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
