  • Lesser Spotted Eagle (Aquila pomarina) colour ringing programme and its first results in the period 2000-2008 in Slovakia

    Co-Authors: Miroslav Dravecký, Stefan Danko, Boris Maderic, Ján Kicko, Dušan Karaska, Karol Šotnár, Stanislav Harvancík, Peter Vrlík, Josef Vrána, Miloš Balla
    Abstract:

    Lesser Spotted Eagle (Aquila pomarina) colour ringing programme and its first results in the period 2000-2008 in Slovakia In Slovakia during 2000-2008, 636 Lesser Spotted Eagles (Aquila pomarina) were marked with readable colour rings with double figure code. This is the highest number of Lesser Spotted Eagles marked in such a way in Europe. From this sample, 621 ind. (97.6 %) were chicks at the nest and 15 ind. (2.4 %) were adult birds which were trapped and consequently ringed. In this period, 2 colour series of rings have been used in Slovakia. In 2000 the ringing started with yellow rings, and up until the end of 2008, 631 ex. (616 young and 15 adults) were ringed. In 2008, the ringing started with light blue series of rings and 5 young at the nest were ringed. In addition to readable rings, aluminium ornithological rings of the Ringing Centres of Czech Republic (NM Praha) and Slovakia (NM Bratislava) have been used. The yellow series was used in fewer numbers also in Germany and Poland for marking the Lesser Spotted Eagle (Aquila pomarina), the Greater Spotted Eagle (Aquila clanga), and eventually their hybrids. In this article the authors reported first observations in Slovakia of such marked Lesser Spotted Eagles in the field. Observed eagles were 1, 2, 4, 5, 7 and 8 years old. Some of them were already breeding and were observed taking care of their chicks.

  • Aquila: adaptive resource control for QoS using an IP-based layered architecture
    IEEE Communications Magazine, 2003
    Co-Authors: Thomas Engel, H. Granzer, B.f. Koch, Martin Winter, Petros Sampatakos, Iakovos S. Venieris, Heinrich Hussmann, Fabio Ricciato, Stefano Salsano
    Abstract:

    Support for quality of service is an essential component of the next-generation Internet. The European research project Aquila is committed to defining a DiffServ-based architecture for delivering on-demand QoS to requesting applications. Focal characteristics of the proposed solution are backward compatibility to the existing Internet and scalability to very large networks. To achieve such goals, Aquila implements an overlaid distributed control layer, the resource control layer, implementing a novel mechanism for dynamic control of intradomain resources, the dynamic resource pool. On the interdomain aspects, the Aquila architecture extends the BGRP framework for the aggregation of interdomain reservations to overcome scalability issues. This article describes the general Aquila architecture, with a special focus on the DRP and BGRP mechanisms.

  • QofIS - Traffic Handling in Aquila QoS IP Network
    Quality of Future Internet Services, 2001
    Co-Authors: Andrzej Bak, Stefano Salsano, Fabio Ricciato, Wojciech Burakowski, Halina Tarasiuk
    Abstract:

    The paper describes the traffic handling mechanisms implemented in the Aquila pilot QoS IP network [10]. The Aquila project enhances the DiffServ architecture concept [1,2,3] by adding new functionality for admission control and resource management as well as by defining new set of network services. Each network service is optimised for specific type of traffic (e.g. nonreactive and reactive) and has its own traffic handling mechanisms. Exemplary measurement results verifying the effectiveness of Aquila approach for providing QoS are also included.

  • ip qos at work definition and implementation of the Aquila architecture
    Lecture Notes in Computer Science, 2001
    Co-Authors: Berthold F Koch, Stefano Salsano
    Abstract:

    The IST project Aquila1 aims to develop a flexible, extendable and scalable Quality of Service architecture for the existing Internet. The core network will be an enhanced DiffServ network providing several dynamically manageable traffic classes with specific QoS parameters, per hop behaviors, and other "guidelines" that realize different network services. A new logical layer has been defined on top of the DiffServ network, the Resource Control Layer. The task of this layer is to control the underlying network in order to provide QoS features to the customers of the network. Resource Control Agent, Admission Control Agent and End-user Application Toolkit (EAT) are the logical components of this architecture. Legacy as well as new QoS-aware applications running on the hosts will use the EAT middleware to benefit from the QoS capabilities of the Aquila architecture. The Aquila project is split into two phases. Now it has completed the definition and implementation and it has run the first trial. The architectural definition and the trial results are discussed in this paper.
