Requirements of a middleware for managing a large, heterogeneous programmable network

Programmable networking is an increasingly popular area of research in both industry and academia. Although most programmable network research projects seem to focus on the router architecture rather than on issues relating to the management of programmable networks, there are numerous research groups that have incorporated management middleware into the programmable network router software. However, none seem to be concerned with the effective management of a large heterogeneous programmable network. The requirements of such a middleware are outlined in this paper. There are a number of fundamental middleware principles that are addressed in this paper; these include management paradigms, configuration delivery, scalability and transactions. Security, fault tolerance and usability are also examined—although these are not essential parts of the middleware, they must be addressed if the programmable network management middleware is to be accepted by industry and adopted by other research projects

Memory Access Efficiency in Deeply Heterogeneous Systems

[EN] This work focuses on the implementation of efficient memory transfers in a highly heterogeneous system. The proposed solution is developed in the context of the MANGO European project, which provides a software and hardware framework to support the deployment of custom multi-accelerator systems, as demanded by the modern HPC performance requirements. The achievements here presented benefit both the memory transfer efficiency as seen by applications running on a host computer and by hardware accelerators. The measured performances show results very close to the ideal ones. Support for weighted memory transfers is also developed, allowing the future implementation of Quality of Service policies regarding memory access bandwidth. This work has been performed during an internship of 5 months. The internship is linked to an agreement between UPV and UniNa (Universita’ degli Studi di Napoli Federico II).[ES] Este trabajo se centra en la implementación de mecanismos de transferencia de memoria eficientes en un Sistema Heterogneo. La solución propuesta en este trabajo se desarrolla en el contexto del proyecto Europeo MANGO, que provee de una plataforma tanto Software como Hardware para el desarrollo de sistemas heterogéneos multi-acelerador, para así hacer frente a las demandas de prestaciones requeridas actualmente en sistemas HPC. Los logros aquí presentados mejoran las transferencias de memoria tanto en las aplicaciones que se ejecutan en el Servidor, como las transferencias que tienen lugar en el sistema Hardware entre los diferentes aceleradores. Los resultados obtenidos en las diferentes pruebas realizadas muestran valores cercanos a los máximos posibles ofrecidos por el Hardware utilizado. Tambieén se ha desarrollado un sistema de reserva de ancho de banda para las diferentes transferencias en curso mediante el uso de pesos, posibilitando la futura implementación de políticas de Calidad de Servicio en las transferencias de memória. Este trabajo se ha llevado a término durante una estancia de cinco meses en la Universitat Politécnica de Valéncia. Esta estancia está vinculada a un acuerdo entre la Universitat Politécnica de Valéncia y la Universitá degli Studi di Napoli Federico II.Scotti, V. (2018).

Extending Comprehensive Maritime Awareness to Disconnected Vessels and Users

After the attacks of 9/11, increased security became a national priority that resulted in a focus on National Maritime Security. Maritime Domain Awareness (MDA) is an initiative developed by the Coast Guard, in partnership with the U.S. Navy and other agencies to increase awareness in the maritime domain in support of maritime security [Morgan and Wimmer, 2005]. The purpose of MDA is to generate actionable intelligence obtained via the collection, fusion and dissemination of information from U.S. joint forces, U.S. government agencies, international coalition partners and commercial entities. This actionable intelligence is the cornerstone of successful counterterrorist and maritime law enforcement operations and is critical to Maritime Security [Morgan and Wimmer, 2005]. The U.S. Navy, as a partner in the development and creation of MDA, has tasked its subordinate commands to identify and define capabilities to support this program. One effort sponsored is the Comprehensive Maritime Awareness (CMA) Joint Capabilities Technology Demonstration (JCTD) [CMA Architecture Team, 2007]. This project supports the CMA JCTD efforts by proposing a deployable system to enable a disconnected vessel to connect to the CMA network. A disconnected user can be seen as a merchant ship, hospital ship or any vessel that is not currently connected to the CMA network. This project's proposed deployable system, as a subset to the CMA network, facilitates information sharing in support of humanitarian efforts worldwide.http://archive.org/details/extendingcompreh109456932N
