Harmony: Holistic messaging middleware for event-driven systems

SUMMARYThe recent development of Web-of-Things (WoT) and Cyber-Physical Systems (CPS) raises a new requirement of connecting abstract computational artifacts with the physical world. This requires both new theories and engineering practices that model cyber and physical resources in a unified framework, a challenge that few current approaches are able to tackle. The solution must break the boundary between the cyber world and the physical world by providing a unified infrastructure that permits integrated models addressing issues from both worlds simultaneously. This paper proposes a framework to integrate WoT and CPS. A case study is presented to demonstrate the advantage of the framework.

“…Harmony utilizes capabilities such as "Managed Multi-Path" connections to ensure that events can be reliably delivered with predictable latencies across local and wide area networks. The ESBs exploiting Harmony do not need to provide the degrees of QoS delivery that Harmony does in their local domains, but if they do, that QoS can be provided in a truly end-to-end manner across the Enterprise [5].…”

This paper describes work that is being performed by Boeing Advanced Air Traffic Management (AATM) to provide initial interoperability between US and European aviation and air traffic control systems. Interoperability is demonstrated by using modern information technology tools and techniques to exchange information between the Boeing AATM test bed in the United States with the European Commission System Wide Information Management Supported by Innovative Technologies (SWIM-SUIT) network. Boeing Research and Technology Europe (BR&TE) in Madrid, Spain is a member of the SWIM-SUIT team. The Boeing AATM test bed in the US consists of nodes in Chantilly, Va., Kent, Washington, and Embry Riddle Aeronautical University in Daytona Beach, Florida. The SWIM-SUIT network has nodes in Madrid, Spain, Brussels, Belgium, Rome, Italy as well as other European cities. The gateway between the two networks is realized by connecting the Boeing facilities in Chantilly, Va., and Madrid, Spain.The Boeing AATM test bed has evolved from an early prototype of the FAA System Wide Information Management (SWIM) initiative. Test bed core services such as messaging, mediation, and user and identity management were used in the US governments multi-agency Joint Network Enabled Operations (NEO) program.

“…These software objects perform various services and interact in a consistent manner. We are adapting a foundational application framework for REON using Internet-scale Control Systems (iCS) [15] technology, and we use Harmony [16] as the network management layer. These technologies have been designed for large-scale implementations where we expect to support hundreds to thousands of sensors and control devices (i.e., actuators) in an inherently heterogeneous environment.…”

Multiparameter and multiscale real-time environmental monitoring of a river and estuary system will be realized through the River and Estuary Observatory Network (REON) for the Hudson River in New York. In this paper, we describe a system under development that provides a holistic view of this complex and dynamic natural environment for scientific research, education, management, and environmental policy-related applications. The system incorporates a complex array of sensor technologies encompassing the physical, chemical, and biological measurement domains. REON supports Lagrangian, Eulerian, and autonomous robot sensor deployments, as well as flexible telemetry options through an open and consistent middleware architecture with advanced device management capabilities. Multimodal data streams are ingested and analyzed by an intelligent distributed streaming data analysis system known as System S. The challenges of managing high volumes of complex heterogeneous data are addressed via a distributed network of intelligent computational nodes that incorporate both autonomic algorithms and active knowledge management including a temporal component. REON provides an adaptive computing environment that provides isotropy in terms of data access and collaborative computation in contrast to traditional hierarchical control systems for sensor environments. Also presented is the underlying information infrastructure that supports a robust and integrated data modeling, simulation, and visualization manifold.
