Network storage WG

This WG plans to provide a new functionality to RNP’s community and to explore the impact of advanced network storage technologies. Its main goal is to implant an infrastructure of temporary data storage with interfaces both for users (via browser), and for applications (via API). This effort will simplify the exchange of information and the publication of mass content, taking as much advantage as possible of the potential of available connections. The work to be developed by this WG will foster information sharing among similar services assembled in other high performance networks, such as Cesnet (from the Czech Republic) and Internet2 (from the United States).

Digital TV WG

This working group plans to create solutions that make open TV transmission through the Internet available and that enhance it, with the resources readily obtainable in the realm of digital TV (including interactivity). This WG’s pilot-experiment aims at developing a platform that can initially facilitate the access of users with heterogeneous characteristics to the content of TV channels distributed through the Internet. Furthermore, support to the inclusion and transmission of these channels will also be part of the platform to be developed for the pilot-experiment. The transmission will use the infrastructure developed by the Digital Video WG in its second phase. This experiment also aims at creating an infrastructure for the registration of TV channels, so that they can take part in the service, through the Digital TV portal.

University access broadband wireless mesh network WG

This WG proposes the implantation of a mesh access network for university users living near their universities. This technology has the advantage of being cheap, easy to implant and very tolerant to failure. The project, named Remesh, has the goal of developing and testing the access via mesh network in the communities located around the several campi of Universidade Federal Fluminense (Fluminense Federal University - UFF). UFF has its campi integrated to several communities in the city of Niterói, including the neighborhoods of Icaraí, Boa Viagem, Ingá, Santa Rosa, besides downtown Niterói. The topology of the city, its high density of population, and the proximity to residential buildings provide the perfect scenery for the implantation of mesh access networks. Besides the scientific and technological aspects, the project aims at social and digital inclusion through the communication networks of Brazilian universities.

Remote visualization WG

This project basically aims at developing and making available to the academic community a multi-user system in order to improve the forms of interaction existing in the current mixed-reality environments (including any manipulative system), making them much more collaborative and accessible to the community. The final result of this project will be a system in which several users - as well as robots, manipulators, and remote visualization (RV) devices - will be able to be connected and acting on the same or different environments. An immediate application of this work is the availability of generally expensive resources (caves, RV devices, robots, manipulators) to the community and the public in general through the Internet, allowing, for instance, their utilization in moments when they are idle.

Video management WG

The first goal of this working group is to investigate and specify a platform of multimedia service management based on the infrastructure and services of RNP’s network. Afterwards, the WG will implement, as conceptual proof, a prototype of a digital video distribution system that takes management aspects into consideration (content storage, recovery and search; authentication and control of users’ and groups’ access; configuration, monitoring and control of the entities in the infrastructure that provides the service; and systems to deliver multimedia content). Thus, this WG’s work will be divided into three main activities: the specification of a platform of multimedia service management, the development of a system for video distribution management, and the testing of the system implemented on RNP’s network integrated to the currently existing services. In order to reach these goals, it is fundamental that this project reutilize, refine and integrate the work previously carried out by RNP’s WGs, such as: the portal and the digital video network of the Digital video WG; the monitoring environment of the Measures WG; and the services and directory scheme of the Middleware and Directory WGs, respectively.

ICP-EDU3 WG – Virtual Smart card and distributed certifying authority

The goal of this WG is to develop cheap and safe solutions for university students, employees and professors to generate, keep and safely use a private key. The path to be followed in this project includes dividing the private key into two shares so that, in order to access each of them, it is necessary to create a valid signature. Thus, one key share may consist of a file under the user’s responsibility, while the other will be stored in a server, duly protected. With this combination, in order to repudiate a signed document, a user has to state that his computer was invaded, and, at the same time, a systems administrator took advantage of his privileges. Although this is possible, the conjunction of these two events is very improbable. We call this solution virtual smart card.

Measures 2 WG

The goal of this WG is to continue the prototyping activities of a measuring infrastructure for RNP, initiated by the Measures WG, so as to make it interoperable with the Sonar environment. Besides, this group intends to adapt Pipes-BR to the GFD architecture; to test Sonar’s prototype and its interoperability with Pipes-BR; and to develop a visualization tool for the final user, which is being called ICE (Internet Computer Network Eye). At the end of this WG, it is expected that the functioning of the Pipes-BR environment can be demonstrated, interoperating with the Sonar environment (Internet2/Géant), and enabling performance tests to be carried out and results to be made available among users in Brazil and abroad, notably in the United States and countries in the European Community. The implantation of this measuring infrastructure will bring benefits to the users of advanced applications (such as grids, video, etc.) of the institutions using RNP, and possibly, also those of Clara network, who will be able to diagnose the state of the network prior to and during the use of their applications.
