“…Few authors have addressed the end-to-end reservation of resources for distributed systems, including processor and network resources. A distributed kernel framework with a resource manager in each node has been designed and implemented to provide an end-to-end timeliness guarantee [19]. Also, a resource management system, called D-RES [20], has been developed to handle shared resources among multiple applications in distributed systems.…”

Complexity in the real-time embedded software domain has been growing rapidly. The component-based software development approach facilitates the development process of such software systems by dividing a complex system into a number of simpler components. Resource reservation techniques have been widely used for providing resources to real-time software components. In this paper we target real-time components operating on a distributed resource infrastructure. Furthermore, we target a class of software components which demonstrate dynamic resource consumption behavior. A prime example of such components is a multimedia software component. In the paper, we present a framework supporting multi-resource endto-end resource reservations. We reserve resource bandwidths on both processor resources as well as on the network resources. The proposed framework utilizes a Multiple Input Multiple Output (MIMO) controller which adjusts the sizes of reservations tracking the dynamic resource demands of the software components. Finally, we present a case study using a multimedia component to demonstrate the performance and efficiency of our framework.

Abstract-A fractionated spacecraft is a cluster of independent modules that interact wirelessly to maintain cluster flight and realize the functions usually performed by a monolithic satellite. This spacecraft architecture poses novel software challenges because the hardware platform is inherently distributed, with highly fluctuating connectivity among the modules. It is critical for mission success to support autonomous fault management and to satisfy real-time performance requirements. It is also both critical and challenging to support multiple organizations and users whose diverse software applications have changing demands for computational and communication resources, while operating on different levels and in separate domains of security.The solution proposed in this paper is based on a layered architecture consisting of a novel operating system, a middleware layer, and component-structured applications. The operating system provides primitives for concurrency, synchronization, and secure information flows; it also enforces application separation and resource management policies. The middleware provides higher-level services supporting request/response and publish/subscribe interactions for distributed software. The component model facilitates the creation of software applications from modular and reusable components that are deployed in the distributed system and interact only through well-defined mechanisms.Two cross-cutting aspects -multi-level security and multilayered fault management -are addressed at all levels of the architecture. The complexity of creating applications and performing system integration is mitigated through the use of a domain-specific model-driven development process that relies on a dedicated modeling language and its accompanying graphical modeling tools, software generators for synthesizing infrastructure code, and the extensive use of model-based analysis for verification and validation.

“…More recently, Rajkumar et al [31] proposed Distributed Resource Kernels, an extension of Linux/RK adding support for distributed real-time applications. Unlike our proposal, in DistributedRK the architecture for the distributed management and allocation of resources is built inside the kernel, presumably for improved efficiency as claimed by the authors, but preventing portability.…”

Management, allocation and scheduling of heterogeneous resources for complex distributed real-time applications is a challenging problem. Timing constraints of applications may be fulfilled by a proper use of real-time scheduling policies, admission control and enforcement of timing constraints. However, it is not easy to design basic infrastructure services that allow for an easy access to the allocation of multiple heterogeneous resources in a distributed environment.In this paper, we present a middleware for providing distributed soft real-time applications with a uniform API for reserving heterogeneous resources with real-time scheduling capabilities in a distributed environment. The architecture relies on standard POSIX OS facilities, such as time management and standard TCP/IP networking services, and it is designed around CORBA, in order to facilitate modularity, flexibility and portability of the applications using it. However, real-time scheduling is supported by proper extensions at the kernel-level, plugged within the framework by means of dedicated resource managers. Our current implementation on Linux supports reservation of CPU, disk and network bandwidth. However, additional resource managers supporting alternative real-time schedulers for these resources, as well as additional types of resources, may be easily added.We present experimental results gathered on both synthetic applications and a real multimedia video streaming case study, showing advantages deriving from the use of the proposed middleware. Finally, overhead figures are reported, showing sustainability of the approach for a wide class of complex, distributed, soft real-time applications.
