16、surement Ontology for IP traffic (MOI). Introduction Defining a complete set of concepts and their relationship to support coherent developments of traffic measurement systems needs not only an extensive mapping of key performance indicators (KPI), key quality indicators (KQI) and currently used par
17、ameters to describe IP networks, but a serious pre-definition of the framework and extension of the ontology to be set up. If it is true that ontologies should be complete and internally coherent, one ought to be aware of the final purpose of establishing such an ontology, namely supporting informat
18、ion systems to achieve IP traffic monitoring and quality of service (QoS) applications that can exchange information and back service level agreements (SLA) up and fulfil the expectations of customers by assuring the quality of experience (QoE). The present document starts setting up the limits to t
19、he ontology that needs to be defined for such purpose. Then, after reviewing the parameters that define IP networks, some use cases are used to analyse which internal specifications should be respected in order to give rise to a coherent ontology for IP traffic monitoring useful for practical purpos
20、es. ETSI ETSI GS MOI 002 V1.1.1 (2012-07) 51 Scope The present document identifies the requirements that should characterise an ontology for the semantic conceptualisation of information related to IP traffic measurements. The requirements are obtained through the analysis of use cases spanning acro
21、ss a variety of related application categories and domains of interest, as well as the consideration of additional qualitative needs, such as the protection of personal data. Additional inputs arise from user experience, as well as the GS/MOI-010 Work Item study, entitled “Report on information mode
22、ls for IP traffic measurement“ 1. The general difficulty of setting limits to an ontology, taking concepts from outside is also dealt within the present document that states MOI focus on IP traffic measurement concepts and lets side ontologies dealing with other subjects, an easy way to link. Thus a
23、 rather practical approach to define MOI ontology will be laid so that further QoS, traffic monitoring and Internet governance issues can be built on top of it by means of semantic tools. 2 References References are either specific (identified by date of publication and/or edition number or version

Douligeris these include the retention of certain data for ensuring their availability if needed for the investigation, detection and prosecution of serious crimes, as well as the performance of Lawful Interception. Different monitoring tools and platforms have been developed
37、 through the years to obtain active and passive measurements about a variety of metrics. The integration of such measurements can be valuable for network operators to obtain network weathermaps or network tomographies. However, this integration in a single view is difficult because each platform use
38、s its own data structures and its own interaction interfaces. ETSI ETSI GS MOI 002 V1.1.1 (2012-07) 9Ontologies can become very useful for the conceptual integration of the different measurement data models. Dealing with the underlying information at a semantic level can enable some degree of infere
39、nce and automatic reasoning over the retrieved measurement data. At the same time, ontologies let define the information at different abstraction levels, allowing the definition of specific classes of measurements that are derived from generic ones. The present document focuses on this approach, app
40、lying the concepts provided by ontologies to address the integration of measurement information from a semantic viewpoint. The MOI ontology has to describe the set of concepts, properties, relationships and axioms in the domain of Internet Network Measurements. In that respect, it is very important
41、to define the limits of the ontology, and also set connections to other already defined and globally accepted ontologies. Given that the network measurement domain is very broad, it is important to be pragmatic, avoiding very large models that are difficult to apply in a real use case. For this, the
42、 ontology will be focused on what can be measured in an Internet Network; Quality of Service (QoS) and Quality of Experience (QoE) will be essential parts of this ontology, whereas special focus will be put on the critical issue of personal data protection as an integral part of the ontology. Other
43、concepts will be taken from other existing ontologies, to a some extent investigated in 1. Other general concepts are also available in already defined network management information models such as the CIM model, SNMP MIBs or ITU M.3100. The work presented here is supported by three European researc
44、h projects. The aim of the FP7 ICT MOMENT i.1 was precisely to find ways to solve the integration problem. This integration was twofold: definition of a standard interface to access the information, as well as definition of a homogeneous view of the available information. For the latter integration,
45、 it was necessary to combine database schemas of the existing network measurement infrastructures, and leverage existing definitions from PerfSONAR, CAIDA, IPPM IETF WG, etc. On the other hand, FP7 ICT PRISM i.2focused on the issue of privacy protection in the context of passive network monitoring;
46、a fundamental activity has been the specification of a semantic model. Finally, this work is supported by the FP7 ICT DEMONS i.3; it focuses on distributed and cooperative network monitoring for fulfilling a variety of objectives mostly centered around security, while it continues the work of PRISM
47、with respect to personal data protection leveraging semantic technologies. Next clauses investigate the requirements that should drive the development of the MOI ontology. A few representative use cases where the MOI ontology can be used are provided, while information domains and types that should
48、be specified in the ontology, such as Key Performance Indicators (KPI), are outlined. Moreover, in order to cope with the personal data protection aspects, the underlying principles are also investigated. As a result, the set of requirements of the ontology are defined, specifying both main features
49、 and global requirements, as well as the requirements for the ontology structure. 5 KPI Descriptions and Mapping to MOI Operators and private network managers require tools to manage the network, prevent and detect problems, plan and engineer sections. The Key Performance Indicators (KPI) serve the purpose of quantifying metrics that reflect factors critical for the correct network behaviour in the sense of operational and/or business objectives.
