QoS adaptation is an important process in inter-domain service mana g ement, since it can g uarantee the correct service provisionin g when unexpected events occur. However, in inter-domain environments, the human interference and the manual-based operations hamper the deployment of expeditious mechanisms to adapt the QoS of the services. This paper(More)
A taxonomic treatment for the 11 species of Elaphoglossum sect. Polytrichia found in Brazil is presented. The species of this section are recognized morphologically by the presence of subulate scales and lack of hydathodes on adult leaves. Two new species are described: E. amorimii and E. brevipetiolatum, both endemic to the Atlantic rainforest of eastern(More)
Elaphoglossum fendleri, a new species from the cloud forests of Venezuela, is here described and illustrated. The type specimens were collected by Augustus Fendler ca. 160 years ago but had gone unnoticed since then. Some authors have confused it with E. ornatum, a subulate-scaled species that is restricted to the Venezuelan Andes. Elaphoglossum fendleri is(More)

Cooperation among service providers, network providers, and access providers in the Internet allows the creation of new services to offer to customers that are in other domains, thus increasing revenue. However, the Internet heterogeneous environment, where each provider has its own policies, infrastructure and business goals, hinders the deployment of more(More)
This paper implements and evaluates a multi-criteria approach to select appropriate service providers in a large scale multi-provider environment. This approach uses the Analytic Hierarchy Process (AHP) method in a Peer-to-Peer Service Overlay Network (P2P SON) composed of several service providers in order to select the most suitable one to deliver the(More)
