April 2005 report
A JRA1 activity meeting was held in Zurich. The meeting was also attended by people from EGEE, Internet2 piPEs and Lobster.
Several questions are being investigated in respect with the licensing and with the implication of the collaboration with Internet2. A joint JRA1-JRA2 meeting was also held to find out the areas of overlap and of interest for each activity.
Work is being carried out to evaluate the Scampi architecture and the MAPI interface (Measurement API) and to investigate the interest of using netflow data within JRA1. Cesnet has worked on defining the commonalities between the Lobster architecture and the JRA1 one. Three scenarios avoiding duplication of work have been suggested. The messages format to be used in the communication between services and a visualisation database schema are being refined. The work on data aggregation and concatenation has started with the definition of a workplan for the task. Investigation on the AA needs for JRA1 is carried out and at this stage; it appears that the JRA1 requirements are the same than the ones from SA3. JRA5 has been notified.
Different technologies have been evaluated and it has been chosen to implement the prototype. A prototype meeting was held following the JRA1 activity one and the following technologies were chosen: web-services, Axis and Tomcat.
Requirement regarding the hardware needed for the activity have been gathered. Different hardware platform are being closely evaluated for the OWD measurements. Quotes are being asked to different vendors. When the result of this work will have been compiled, the activity will be able to start the process of buying the equipments.
