data distribution service

Software-defined networks (SDNs) have caused a paradigm shift in communication networks as they enable network programmability using either centralized or distributed controllers. With the development of the industry and society, new verticals have emerged, such as Industry 4.0, cooperative sensing and augmented reality. These verticals require network robustness and availability, which forces the use of distributed domains to improve network scalability and resilience. To this aim, this paper proposes a new solution to distribute SDN domains by using Data Distribution Services (DDS).

NASA Langley Research Center identified a need for a distributed simulation architecture that enables collaboration of live, virtual, and constructive nodes across its local area network with extensibility to other NASA Centers and external partners. One architecture that was prototyped and evaluated employed Data Distribution Service (DDS) middleware and the GovCloud cloud computing service. The nodes used DDS to exchange data.

As recent technology trends usher us into the many-core era, software applications must scale as 1000s core become available in a single chip. Middleware is a key infrastructure component between applications and the operating system. Therefore, new middleware mechanisms must be developed to handle scheduling, resource sharing, and communication on platforms with 100s and 1000s of cores. The solution must help application developers create concurrent software and must be easy to use.

ABSTRACT: Publish/subscribe (pub/sub) middleware platforms for event- based distributed systems often provide many configurable policies that affect end-to-end quality of service (QoS). Although the flexibility and functionality of pub/sub middle- ware platforms has matured, configuring their QoS policies in semantically compatible ways has become more complex.

Abstract: Recent trends in distributed real-time and embed- ded (DRE) systems motivate the development of infor- mation management capabilities that ensure the right information is delivered to the right place at the right time to satisfy quality of service (QoS) requirements in heterogeneous environments.
