A well-known approach to intradomain traffic engineering consists in finding the set of link weights that minimizes a network-wide objective function for a given intradomain traffic matrix. This approach is inadequate because it ignores a potential impact on interdomain routing. Indeed, the resulting set of link weights may trigger BGP to change the BGP next hop for some destination prefixes, to enforce hot-potato routing policies. In turn, this results in changes in the intradomain traffic matrix that have not been anticipated by the link weights optimizer, possibly leading to degraded network performance. We propose a BGP-aware link weights optimization method that takes these effects into account, and even turns them into an advantage. This method uses the interdomain traffic matrix and other available BGP data, to extend the intradomain topology with external virtual nodes and links, on which all the well-tuned heuristics of a classical link weights optimizer can be applied. A key innovative asset of our method is its ability to also optimize the traffic on the interdomain peering links. We show, using an operational network as a case study, that our approach does so efficiently at almost no extra computational cost. [less ▲]

The objectives of this deliverable DL44 are to finalize the description of the global groundwater vulnerability assessment methodology, in particular : (1) to propose an extension of the concept of sensitivity coefficient to vulnerability coefficient by introducing a ratio (distance to damage ratio) that reflects the “distance” between the current state of degradation of the water resource system and the “damaged state”,(2) To describe the methodology proposed to combine, through aggregation of spatiallydistributed indicators and multi criteria analysis, the different vulnerability coefficientsinto a single indicator of groundwater vulnerability for decision making, (3) To go further into the analysis and discussion of several key theoretical “case studies” for illustrating the way to setup the full methodology, from the DPSIR analysis to the expression of sensitivity and vulnerability coefficients.

To understand and predict the behaviour and transfer of diffuse contamination, a small catchment is intensively studied in the vicinity of Paris. A multi tracer test involving a new technique, the FVPDM method (Finite Volume Point Dilution Method - Brouyère et al., 2008) has been performed in natural flow conditions. Injections of four different tracers (uranine, sulforhodamine B, lithium chloride and potassium iodide) took place in four piezometers involving different areas of the aquifer and different depth. This tracer test follows a former test briefly described. A particularly long monitoring (Nov-2005 to Feb-2008) demonstrates the existence of several transport velocities within the sandy layer, which seems linked to the decrease of hydraulic conductivity with depth. Absence of recovery of two tracers confirms the results of the former test and identifies spatial heterogeneities probably due to the geological structure. The new insight and parameter quantification brought by interpretation of these tests contributes to a better characterization of the saturated zone and shall be exploited through modelling for transport predictions of pesticides.

This draft describes a simple network-based protocol to facilitate Path Selection and to improve traffic engineering capabilities in multihomed corporate networks. With this protocol, any network device that requires to select a path among a list of different paths asks a Traffic Engineering service called IDIPS (ISP-Driven Informed Path Selection) to obtain an ordered list of the possible paths. The ordering is constructed according to policies and performance requirements of both the host and network provider [less ▲]

Pourquoi admettre un réel statut juridique au principe de précaution ? L’exemple des pollutions des mers par hydrocarbure nous fait dire qu’il est aujourd’hui nécessaire de reconnaître au principe de précaution, un réel statut juridique. Notre hypothèse : ce principe peut être fondateur de droit, particulièrement, de droit de la responsabilité. Nous le démontrons en nous appuyant sur trois arguments : l’éthique, la règle du standard et la règle de la contrainte. [less ▲]

This deliverable first analyzes some integration problems encountered during the integration of the O’CoP ontology that was developed by several ontologists. Then, we describe several experiments of development of CoP-specific ontologies · Natural Language processing (NLP) tools were used by Knowledge Management (KM) service developers for analyzing a corpus of e-mails of the @pretic CoP, so as to develop a “Technical Problem” ontology. We also reused an existing hierarchy in order to build the Ontopedia ontology. Last, the development of the ontologies “Human Problems” and “Learning and Teaching” for the @pretic CoP relied on brainstormings between the CoP mediator and the CoP members. · For the Form@Hetice CoP, the ontology was aimed at being used by the BayFac system offering service of document classification, and was developed by the service developers, with a validation by the Form@Hetice CoP mediator. · For Learn-Nett CoP, the ontology was also aimed at being used by the BayFac system, and was developed by the service developers and the CoP mediator (who was also a member of the CoP), with a continuous validation by a CoP focus group. · For the TFT CoP, tbe ontology was developed manually by the CoP mediator through a folksonomy obtained using tags on the CoP documents, according to social tagging approach. At the end of the deliverable, we compare these different ontologies with related work and we analyze them from reusability viewpoint [less ▲]

Wallonia (Southern Region of Belgium) implemented the Nitrates Directive through a first actions plan in 2002 followed by a second action plan in 2007. It designated vulnerable zones and introduced various mandatory practices in order to reduce the nitrate contamination risk. . In Wallonia, nitrate-related problems are obvious in several groundwater bodies and their trends over the past 30 years are worrying. The main part of the contamination level is due to agricultural diffuse pollution. Nevertheless, some pollution peaks are observed mainly coming from domestic sewage. In order to assess the global effectiveness of all the mitigation practices, we have been developing a hydrological model spatially distributed using a 1km² grid cell on the whole Region (16 900 km²). The EPICgrid model represents the root zone and the vadose zone. In Wallonia, groundwater tables are more than 30 m deep in 8% of the territory. It is therefore of major importance to fill the gap between the root zone and the groundwater bodies. It allows us to assess the nitrate transfer time and forecast the mitigation measures’ effect in time, space and amplitude. On the ground, runoff and sediment yield are modelled at the small watershed scale. This report presents an complete analysis of the mitigation measures implemented in Wallonia and their effects forecasted until 2015. [less ▲]
