    ARGON: Reservation in Grid-enabled Networks
    (1. DFN-Forum Kommunikationstechnologien – Beiträge der Fachtagung, 2008) Barz, Christoph; Bornhauser, Uli; Martini, Peter; Pilz, Markus; Waal, Christian de; Willner, Alexander
    Grid computing offers heterogeneous and distributed resources to scientific communities. Apparently, networks connecting these resources can also be consid- ered as Grid resources. This paper presents ARGON, a system that integrates metro and wide area networks into Grid environments by providing advance reservations and guaranteed network services. Here, single-domain as well as multidomain network environments are considered. A major objective is to support metaschedulers in the planning of workflows for e-science applications with demanding network requirements.

    Receiver-based path capacity estimation for TCP
    (Kommunikation in Verteilten Systemen (KiVS), 2005) Barz, Christoph; Frank, Matthias; Martini, Peter; Pilz, Markus
    This paper presents a new TCP-based packet pair measurement approach for network path capacity estimation. It addresses some drawbacks other approaches still bear. In contrast to these, our approach uses an unmodified TCP sender and utilizes techniques to identify probing packets that were less influenced by cross traffic. These techniques are applied at the receiver side only. The concept is verified by simulation and an outline of the applicability for real-life measurements in the Internet is presented.
