Deliverable JRA1.1: Evaluation of current network control and management planes for multi-domain network infrastructure

This deliverable includes a compilation and evaluation of available control and management architectures and protocols applicable to a multilayer infrastructure in a multi-domain Virtual Network environment.The scope of this deliverable is mainly focused on the virtualisation of the resources within a network and at processing nodes. The virtualization of the FEDERICA infrastructure allows the provisioning of its available resources to users by means of FEDERICA slices. A slice is seen by the user as a real physical network under his/her domain, however it maps to a logical partition (a virtual instance) of the physical FEDERICA resources. A slice is built to exhibit to the highest degree all the principles applicable to a physical network (isolation, reproducibility, manageability, ...). Currently, there are no standard definitions available for network virtualization or its associated architectures. Therefore, this deliverable proposes the Virtual Network layer architecture and evaluates a set of Management- and Control Planes that can be used for the partitioning and virtualization of the FEDERICA network resources. This evaluation has been performed taking into account an initial set of FEDERICA requirements; a possible extension of the selected tools will be evaluated in future deliverables. The studies described in this deliverable define the virtual architecture of the FEDERICA infrastructure. During this activity, the need has been recognised to establish a new set of basic definitions (taxonomy) for the building blocks that compose the so-called slice, i.e. the virtual network instantiation (which is virtual with regard to the abstracted view made of the building blocks of the FEDERICA infrastructure) and its architectural plane representation. These definitions will be established as a common nomenclature for the FEDERICA project. Other important aspects when defining a new architecture are the user requirements. It is crucial that the resulting architecture fits the demands that users may have. Since this deliverable has been produced at the same time as the contact process with users, made by the project activities related to the Use Case definitions, JRA1 has proposed a set of basic Use Cases to be considered as starting point for its internal studies. When researchers want to experiment with their developments, they need not only network resources on their slices, but also a slice of the processing resources. These processing slice resources are understood as virtual machine instances that users can use to make them behave as software routers or end nodes, on which to download the software protocols or applications they have produced and want to assess in a realistic environment. Hence, this deliverable also studies the APIs of several virtual machine management software products in order to identify which best suits FEDERICA’s needs.Postprint (published version

AUGUSTO DOS ANJOS: POETRY, PAIN AND A HEIGHTENED AWARENESS OF BEING

Este artigo propõe uma leitura intertextual entre a obra do poeta brasileiro Augusto dos Anjos e alguns textos selecionados da filosofia existencialista do século XX. O tema da dor como instância ontológica de manifestação do indivíduo e sua repercussão na praxis vital decorrente da perspectiva fenomenológica-existencialista aproxima o poeta brasileiro da obra de Jean-Paul Sartre. A noção do absurdo em Dos Anjos consubstancia a ideia da miséria da condição humano frente ao outro e corrobora com a percepção sartreana do nada como auto-reflexividade da consciência

Augusto dos Anjos : poetry, pain and heightened awareness of being

This article attempts at an intertextual reading of Brazilian poet Augusto dos Anjos together with selected texts of twentieth-century existential philosophy. The theme of pain as an ontological ground of individual manifestation and its conformity with the vital praxis described in existential phenomenology corroborates the possibilities of intertextuality among the works of Jean-Paul Sartre and dos Anjos. The notion of the misery of human condition face to face with the other brings both writers together under the concept of nothingness as the self-reflexivity of consciousness.este artigo propõe uma leitura intertextual entre a obra do poeta brasileiro Augusto dos Anjos e alguns textos selecionados da filosofia existencialista do século XX.

Hagiwara Sakutarô, Buddhist realism, and the establishment of japanese modern poetry

This article approaches the works of poet Hagiwara Sakutarô (1886-1942) from a comparative perspective that engages philosophy and literature. The philosophical dimension of Sakutarô’s poetry is analyzed by means of inter-textual readings that draw on the tradition of Buddhist epistemology and on the texts of logicians Dignāga and Dharmakīrti (5th century). The comparative analysis is considered under the perspective of the influence of Naturalism and the use of description in the emergence of Japanese modern poetry. Pointing to the possibility of a Buddhist realism that shares some common characteristics with Naturalism, the article emphasizes the Buddhist dimension of Sakutarô’s poetry, which appears in spite of the poet’s turn to Western philosophy (notably to Schopenhauer, Nietzsche, and Kant), as well as to his overt rejection of Buddhism as a necessary step to the modernization of the Japanese letters.Este artigo aborda a obra do poeta Hagiwara Sakutarô (1886-1942) a partir de uma perspectiva comparativa que engaja filosofia e literatura. A dimensão filosófica da poesia de Sakutarô é analisada por meio de uma leitura intertextual entre a obra do poeta japonês e a epistemologia budista presente nos textos em sânscrito dos filósofos Dignāga and Dharmakīrti (século V). Essa análise comparativa é efetuada sob a perspectiva da influência do naturalismo europeu no surgimento da poesia japonesa moderna. Demonstrando a possibilidade de um realismo budista que compartilha importantes características estéticas com o naturalismo, o artigo enfatiza a dimensão budista da poesia de Sakutarô, a qual se desvela apesar da rejeição ao budismo operada pelo próprio poeta como passo necessário para o estabelecimento da modernidade nas letras japonesas

Deliverable DJRA1.2. Solutions and protocols proposal for the network control, management and monitoring in a virtualized network context

This deliverable presents several research proposals for the FEDERICA network, in different subjects, such as monitoring, routing, signalling, resource discovery, and isolation. For each topic one or more possible solutions are elaborated, explaining the background, functioning and the implications of the proposed solutions.This deliverable goes further on the research aspects within FEDERICA. First of all the architecture of the control plane for the FEDERICA infrastructure will be defined. Several possibilities could be implemented, using the basic FEDERICA infrastructure as a starting point. The focus on this document is the intra-domain aspects of the control plane and their properties. Also some inter-domain aspects are addressed. The main objective of this deliverable is to lay great stress on creating and implementing the prototype/tool for the FEDERICA slice-oriented control system using the appropriate framework. This deliverable goes deeply into the definition of the containers between entities and their syntax, preparing this tool for the future implementation of any kind of algorithm related to the control plane, for both to apply UPB policies or to configure it by hand. We opt for an open solution despite the real time limitations that we could have (for instance, opening web services connexions or applying fast recovering mechanisms). The application being developed is the central element in the control plane, and additional features must be added to this application. This control plane, from the functionality point of view, is composed by several procedures that provide a reliable application and that include some mechanisms or algorithms to be able to discover and assign resources to the user. To achieve this, several topics must be researched in order to propose new protocols for the virtual infrastructure. The topics and necessary features covered in this document include resource discovery, resource allocation, signalling, routing, isolation and monitoring. All these topics must be researched in order to find a good solution for the FEDERICA network. Some of these algorithms have started to be analyzed and will be expanded in the next deliverable. Current standardization and existing solutions have been investigated in order to find a good solution for FEDERICA. Resource discovery is an important issue within the FEDERICA network, as manual resource discovery is no option, due to scalability requirement. Furthermore, no standardization exists, so knowledge must be obtained from related work. Ideally, the proposed solutions for these topics should not only be adequate specifically for this infrastructure, but could also be applied to other virtualized networks.Postprint (published version
