“…Relative to the traditional message bus architecture [7,8] built by centralized control mode, the distributed real-time message bus architecture with self-organizing characteristic is incomparable regardless of size, complexity, distributivity and isomerism. In this paper, the message bus architecture supports a series of features like self-healing, self-managing, self-discovering, self-planning, self-adjusting, and self-optimizing.…”

Abstract. This paper discusses on the cyber-physical system technology that assures the interoperability of manufacturing control system and equipment in intelligent manufacturing domain. This technology involves an information exchange and communication process, where broad manufacturing resources of production workshops in advanced manufacturing industries such as control system, equipment, personnel, and materials may freely enter or exit from the distributed self-organizing peer-to-peer network as independent message nodes. In this process, an improved filtering and routing algorithm based on topic and eigenvalue similarity is also employed to group and compress massive manufacturing messages in the light of semantics and message clusters for the purpose of intelligently identifying, positioning, tracking, monitoring and managing manufacturing resources. Based on the features of manufacturing process, this paper filters messages and implements end-to-end batch compression and transmission so as to ensure that the massive messages transmitted among different manufacturing resources in the intelligent manufacturing process are equipped with the advantages like real time, fault tolerance and high robustness when data validity is guaranteed.

“…al. [7] propose parametric subscriptions in order to provide support for dynamic subscription adaptations. They enrich content-based Publish/-Subscribe system with the ability for the subscriber to dynamically update its subscription without loosing any events that occur between the adaptations.…”

Abstract. Current publish/subscribe systems provide very limited support to modify subscriptions dynamically. Consequently, they cannot efficiently control the flow of events between publishers and subscribers, which may lead to unnecessary network traffic. In addition, it is not possible to automatically subscribe or unsubscribe to a service depending on certain context of use. This implies for developers to manually manage subscriptions (e.g., taking care of when to cancel or re-issue a subscription), which may result in inappropriate subscription states (e.g., subscriptions that are cancelled too late). In this paper, we propose the concept of dynamic subscription mechanisms that improves the expressiveness and flexibility of subscriptions. We introduce a new dimension to a subscription that allows a subscriber to express the flow of matched events, and when a new subscription can be (re)issued. We validate our claims for improved flexibility and expressiveness by providing language abstractions and a prototype implementation of a dynamic subscription mechanism framework called Flexub that supports a variation of subscription mechanisms. When compared to existing subscription models, our experiment results show that the support for dynamic subscription mechanisms greatly reduces network traffic of events sent from publishers to the subscribers. In addition, our approach reduces the workload on the subscriber side.

“…EventJava thus supports parametric subscriptions [22,25], i.e, dynamic guards, by allowing for fields of consumer objects to be used in guards. In EventJava an example like the following looks like quite natural:…”

“…At each subscriber, all the generated subscriptions compared event attributes to expressions on field variables. We did not use any single-field guards because the benefits of using single-field guards has already been exhaustively evaluated by [25]. 50% of the generated subscriptions at each subscriber used arithmetic expressions on variables, while the remaining 50% used functions from java.lang.Math.…”

“…Besides allowing for statically verifying compliance of subscriptions with the events they are expressed on, guards naturally capture advanced features such as parametric subscriptions [22,25] which have been shown to benefit efficiency. In contrast to an API-based support for the subscriber-local variables underlying such subscriptions, programming language support allows for complex subscriptions, e.g., those involving arithmetic and multiple variables to be expressed, and for the compiler to automatically simplify these and infer the relevant parameters.…”

Designing distributed applications around the idiom of events has several benefits including extensibility and scalability. To improve conciseness, safety, and efficiency of corresponding programs, several authors have recently proposed programming languages or language extensions with support for event-based programming.The presence of a dedicated programming language and compilation process offers avenues for program analyses to further improve simplicity, safety, and expressiveness of distributed event-based software. This paper presents three program analyses specifically designed for event-based programs: immutability analysis avoids costly cloning of events in the presence of co-located handlers for same events; guard analysis allows for simple yet expressive subscriptions which can be further simplified and handled efficiently; causality analysis determines causal dependencies among events which are related, allowing unrelated events to be transferred independently for efficiency. We convey the benefits of our approach by empirically evaluating their performance benefits.
