    Abstract

    This report contains the result of a ‘proof of concept’ study that was performed by the CTIT of the University of Twente, together with ESYS Limited (Guildford, UK) for the Institute of Remote Sensing Applications of the Joint Research Centre (JRC) of the EC (Ispra, Italy). The study is part of the ‘Centre of Earth Observation’ (CEO) programme.

    The subject of the study was the design and implementation of tools that allow status and utilisation monitoring of networks and distributed information servers. In the specific case of the CEO programme, these information servers are accessible via the WWW and contain large amounts of earth observation data (e.g. satellite pictures).

    The work division within the project was that ESYS investigated the management applications, which had to run on top of HP-Openview, and the CTIT designed and implemented the management agents. These agents had to include the following Management Information Bases (MIBs):
    • A HTTP-MIB, with detailed information concerning the WWW document transfer protocol.
    • A Retrieval Service (RS) MIB, with high level information concerning the WWW document transfer service.
    • An Information Store (IS) MIB, with information concerning the WWW server and the documents provided by that server.
    The specifications of these MIBs were presented to the IETF and provided a good starting point for subsequent standardization activities. The agents were implemented as sub-agents of the EMANATE extensible agent package and are currently being tested in a number of field trials.
