1. Upgrading and extending PON by using in-band WDM overlay
This paper presents a new approach to upgrade and extend the reach of the current passive optical network (PON) by using wavelength division multiplexing (WDM) in the standardized optical grid of gigabit PON (In-band WDM PON overlay). The aim is to increase the number of optical distribution networks (ODNs) fed by a single fiber while preserving the users ba

2. Overlays building protocol to video distribution in P2P networks. / Protocolo para a construção de overlays para distribuição de streamings em redes P2P.
The Internet development has leveraged several kinds of application that depends on its infrastructure, such as P2P applications to voice/video streaming transmission. These applications have a plenty of requirements, such as bandwidth, latency, jitter, scalability, availability, and so on, that should be fulfilled in order to achieve the required level of Q

3. Future internet architecture to structure and to manage dynamic autonomous systems, internet service providers and customers
In recent years, the problem of dynamic networks has received a great deal of attention from the network research community. This problem consists in providing for the Internet architecture a set of mechanisms, such as addressing, information management and information forwarding, which support mobile information and mobile entities (Autonomous Systems, Inte

4. Uma alternativa a inundação baseada em tabelas de dispersão para planos de controle de redes opticas / A hash table based flooding alternative for optical networks control plane
The transport layer structure of the Internet is moving towards a model of highspeed routers interconnected by intelligent optical core networks. A consensus has been reached on wavelength division multiplexing (WDM) as the way to increase the transmission capacity. However there are few proposals for distributed control planes under dynamic Quality of Servi

5. Uso de small worlds no roteamento em redes de sensores sem fio / Use of small worlds in wireless sensor networks routing
In this work, has made an study about the use and influences of the small world effect, or six degrees of separation, in routing of wireless sensors network (WSNs). For this objective, was analyzed the characteristics of WSNs that influence in the routing and the different types of protocols. Moreover, was studied the characteristics of small world effect an

6. Hermes: a framework for P2P application programming / Hermes: um arcabouço para a programação de aplicações P2P
Hermes is a framework for P2P application programming. Using it, one can create several kinds of distributed applications without worrying about the underlying network. Hermes is not a P2P overlay network implementation, but a shell envolving existing implementations. The application developer is isolated from the implementation of the overlay network in use

7. Arquitetura e prototipação de uma UNI optica para a rede GIGA / Architecture and prototype of an optical UNI for the GIGA network
The main interests of the GIGA Project are the deployment of Optical Network Technology, Network Services and Applications, Experimental Telecommunication Services and Scientific Applications. In the context of this Project, our research group has been working on the design of an IP/WDMControl Plane to integrate the IP/MPLS Client Network with the Optical Tr

8. Uma arquitetura P2P baseada na hierarquia do endereçamento IP com roteamento unificado
Entre as diversas abordagens para se aproveitar os recursos computacionais ociosos existentes nas folhas da Internet, ou seja, nas máquinas dos usuários, as redes peer-to-peer (P2P) vêm ganhando destaque especial nos últimos anos devido principalmente à sua escalabilidade, desempenho e tolerância à falhas. As arquiteturas P2P atuais, entretanto, ainda

9. Estudo comparativo de tÃcnicas de restauraÃÃo de caminhos em redes de serviÃos
The point-to-point communication (link) in a network such as the Internet may fail. Restoration techniques can be used to preserve this communication, from other links, making new paths. This restoration represents a cost increase related to the original path. In an overlay service network, there are many distributed services among the nodes. To do a task, w
