The Metric Concatenation Framework progressed. DJ1.2.3 was near to completion. The OWD tests had to be re run because of hardware restrictions. Steven Van den Berghe submitted an individual Internet Draft on metric composition to the IETF's IPPM WG. This draft is an outcome from the Metric Concatenation Framework (MCF) work and will be discussed at the next IETF Vancouver's meeting, beginning of November.

Discussion on which tests should and can be performed were held. The definition of the tests procedures should be finalised by the end of November. The final conclusions on tests to be performed will be reported in DJ1.3.1.

Further Measurement Archives services (MA) were deployed by early adopters ESnet (US Department of Energy’s network) and Uninett (Norway). Work is undertaken to improve the MA. It will then be tested against the tests procedure and once the tests will be successful, the first non-prototype release of the MA will be provided. A version of the MA in python was implemented. The work on the Lookup service progressed on the front of auto-registration and keepalives.

Three tools are making use of the MAs data: the CNM tool (map based tool), the EGEE NPM diagnostic tool and the ESnet traceroute based visualisation tool. The three of them retrieves link capacity and link utilisation from the one or several of the above-mentioned networks. The improvements on the OWD visualisation back-end were showed to the partners.

Netflow and passive measurement equipment were ordered. IPPM-AB equipments and their GPS antenna were started to be shipped and installed.

A joint JRA1-JRA3 mailing list was created to work on L2 circuits monitoring. DJ1.2.2 on “Base services detail design and API” went through its first review. The JRA1 work was presented during the Ljubljana APM meeting. Interests were showed for some of its used (JRA1 work in general and path based visualisation). A paper on the schema was submitted at the Networking 2006 conference.
