NETCONF is proposed as a new standard protocol for configuration and management of network devices. NET-CONF provides standardized way to configure heterogeneous networks. Currently, one of the obstacles to its widespread adoption is a lack of programming tools allowing developers to easily add NETCONF protocol support into the configuration tools and network devices. libnetconf library provides such functionality. This paper presents possibilities of using libnetconf for a development of network management applications and network device controllers supporting NETCONF protocol. We describe NETCONF functions provided by libnetconf as well as guidelines for utilizing libnetconf library to develop network management applications. © 2013 IFIP. Source

The European Middleware Initiative is a collaboration of the three major middleware providers in Europe, ARC, gLite and UNICORE, and other consortia. EMI aims to deliver a consolidated set of middleware components for deployment in EGI, PRACE and other DCIs; extend the interoperability between grids and other computing infrastructures; strengthen the reliability of the services; and establish a sustainable model to maintain and evolve the middleware, fulfilling the requirements of the user communities.\nEuropean scientific research has benefited recently from the increasing availability of computing and data infrastructures with unprecedented capabilities for large scale distributed initiatives. These infrastructures are largely defined by enabling middleware. After the necessary initial period of research and consolidation that has taken place in the past several years, the growing usage of these resources now requires the transformation of the computing infrastructures into a professionally managed and standardized service. It is of strategic importance for the establishment of permanent, sustainable research infrastructures to lower the technological barriers still preventing resource owners from federating the resources, and potential communities of tens of thousands of researchers from using grids as a commodity tool in their daily activities.\nThe EMI project will make the realization of this vision possible by addressing a number of problems that still prevent users from easily accessing and using the whole capacity of the existing computing infrastructures. It will focus on improving the usability and accessibility for scientific users and the interoperability and manageability for service providers. The sustainability of the grid services will be directly addressed by replacing wherever possible proprietary technology with off-the-shelf components, improving their standardization and implementing industry standard quality assurance methodologies.

Over the past 6 years, the EC has invested to extend the European eInfrastructure technology and European eInfrastructure (and particularly Grid) operational and organisational principles to a number of regions in the world, and reinforcing the close collaboration and exchange of know-how with similar technologies in other areas. A number of different collaboration models have thus been established between Europe and the rest of the world, while the projects implementing these collaborations have had impacts typically focused on their regions. The CHAIN project aims to coordinate and leverage these efforts and their results with a vision of a harmonised and optimised interaction model for eInfrastructure and specifically Grid interfaces between Europe and the rest of the world. The project will elaborate a strategy and define the instruments in order to ensure coordination and interoperation of the European Grid Infrastructures with other external e-Infrastructures. The CHAIN consortium, consisting of leading organisations in all the regions addressed by the project, will ensure global coverage, European leadership, and most efficient leveraging of results with respect to preceding regional initiatives. First, the project will define a coherent operational and organisational model, where a number of EU countries/regions will possibly act, in collaboration with EGI.eu, as bridges/gateways to other Regions/Continents. Further, the project will validate this model by supporting the extension and consolidation of worldwide virtual communities, which increasingly require distributed facilities (large instruments, distributed data and databases, digital repositories, etc.) across the regions for trans-continental research. Finally, the project will act as a worldwide policy-watch and coordination instrument, by exploring and proposing concrete steps for the coordination with other initiatives and studying the evolution of e-Infrastructures.

The presented invention enables the reception of video signals with variable channel synchronization. All logic elements are located on the receiver side that can work with any transmitter. The receiver comprises one or more sets of modules for image processing. These sets of modules adapt the speed of sending data to the frame generator to the speed of data creation on the transmitter side without the use of a precise time pulse source on both sides of the transfer and without feedback from the receiver to the transmitter. The receiver further includes a memory of channel synchronization configuration which determines the allocation of synchronized channels to groups and the detector of starts of frames. These, along with multiplexers of clock signals, ensure the synchronization of channels within groups and allows for modifying this channel distribution.

CHAIN-REDS vision is to promote and support technological and scientific collaboration across different eInfrastructures established and operated in various continents, in order to facilitate their uptake and use by established and emerging Virtual Research Communities (VRCs) but also by single researchers, promoting instruments and practices that can facilitate their inclusion in the community of users. The project aims to support and disseminate the best practices currently adopted in Europe and other continents, and promote and facilitate interoperability among different regional eInfrastructures. CHAIN-REDS gathers the main stakeholders of regional eInfrastructures, collectively engaged in studying and defining a path towards a global eInfrastructure ecosystem that will allow VRCs, research groups and even single researchers to access and efficiently use worldwide distributed resources (i.e. computing, storage, data, services, tools, applications). The core objective of CHAIN-REDS project is to promote, coordinate and support the effort of a critical mass of non-European eInfrastructures for Research and Education to collaborate with Europe addressing interoperability and interoperation of Grids and other Distributed Computing Infrastructures. From this perspective, CHAIN-REDS will optimise the interoperation of European infrastructures with those present in other 6 regions of the world, both from development and use point of view, and catering to different communities.\nOverall, CHAIN-REDs will provide input for future strategies and decision-making regarding collaboration with other regions on eInfrastructure deployment and availability of related data; it will raise the visibility of eInfrastructures towards intercontinental audiences, covering most of the world and will provide support to establish globally connected and interoperable infrastructures, in particular between EU and the developing regions.
