From GEANT2-JRA1 Wiki
September 2005 report
A prototype development week was held in Poznan (Poland). This was jointly organised with ESnet and Internet2. Thirteen people attended the workshop. Progress was made on design, on the interfaces, and refining the workplan to lead us to the December implementation milestone. A one day joint meeting about AA with a JRA5 participant was held during that meeting. This leads to the writing of a draft document on AA specification for JRA1.
The work on data aggregation and concatenation progressed well. Theoretical analysis of monitoring data collected via independent measurement tests is still in progress. Tests were devised on the IPPM OWD measurement tools. The data collected during those tests will be used to verify the concatenation method defined by the MCF group.
An examination to find the best way to visualise metrics has been performed. The goal of this analyse is to provide feedback to the people developing visualisation interface about their visualisation and features they should covers. The outcome is available on the GÉANT2 JRA1 wiki.
The JUnit package has been evaluated to help us performing some tests of the software we are building.
The Lookup service, allowing the discovery of services and of measurement capabilities, has been defined as well as its interfaces. A first prototype version was implemented using an XML database to store the lookup information.
Two Measurement Archives (MA) were deployed on Abilene and GÉANT. They are providing link utilisation and link capacity information from the Abilene and GÉANT Round Robin Databases. The EGEE Network Performance Monitoring diagnostic tool is accessing the information provided by those two MAs. The CNM visualisation tool is also capable of retrieving data from those measurement archives and will be soon able to present those data in a uniform way. In addition to the java MA, a python version has been developed.
The CNM SUN server has been set-up. The DFN IPPM OWD Tools have been configured and are ready to be shipped to their final destinations. There tools will be used as a testbed for the JRA1 activity to test functionalities on a sandpit and to allow users to test the enhancements made.
A first version of the DJ1.2.2 – Detailed Design has been produced.
