  1. WP3 Specification of Inter-domain QoS Analysis Architecture WP3 part of the presentation for the Brussels review meeting on the 12th of march, 2003

  2. Goal of INTERMON • enhance the inter working of tools for QoS and traffic analysis in large-scale, multi-domain Internet networks • collect, process and present (in an automatic fashion) information about: • Network topology, Traffic flows, QoS, and SLA fulfillment • using these instruments: • Topology detection and traffic measurement tools • Distributed information base • Analytical models and simulations based on measurements • Visual data mining techniques

  3. Goal of WP3 • integration of existing tools into INTERMON architecture • development of a scalable architecture for integration of various components for: • topology discovery, traffic measurement, • traffic modelling, network behaviour simulation • data aggregation and visual data mining • building a common graphical user interface for data access • main focus of WP3: define the common interfaces for the different tool classes, define control/data structures and the component setup for the required connectivity

  4. Subtasks of WP3 • build central instance for toolkit control and communication • interfacing to other work packages • WP4: database access, topology detection, IPFIX meter • WP5: simulation and modelling • WP6: GUI and VDM • make data from measurement available to modelling, simulation and visual data mining • coordination of control and data flows in order to implement a system to run the proposed user-level usage scenarios

  5. WP3 Status • D2 document delivered in time (august 2002) • all selected tools have been set up by partners • integration has partially started, e.g. between • data sources and data collection • data repository and client GUI • not all interfaces completely specified yet • work on central control components and overall integration work just started • integration within common GUI currently in progress

  6. Architecture Specification • starting from the logical description of the INTERMONarchitecture functionality stated in previous deliverables additional design deliverable D4 was deployed in order to address the following topics: • Scalability, Reliability, and Security • D4 represents the basis for next steps in the upcoming implementation and integration phases • Three main system components (in addition to tools): • Global Controller (main data base, central control instance) • Local Controller (distributed local data bases, load balancing) • Tool Manager (tool specific control and data collection)

  7. Further Plan • technical specification of remaining interfaces until April’03 • specification of interaction of components within the proposed usage scenarios until June 2003 • refinement of graphical integration within common GUI • implementation work on central control components and interfacing (middleware) to the existing tools and data bases • integration meeting in June will produce first‘all-together’ setup and enhanced testing possibilities

  8. Innovations • centralized common control instance for numerous instances of very different tools • abstractions from specific tools (e.g. different meters) • integration of different result types (routing information, accounting records, QoS metrics) • connection of diverse components/services such as traffic metering, modelling, simulation and visual data mining in one analysis and visualization pipeline

  9. Exploitation Plans • present open concept which allows easy integration of further tools later on • cooperation with SCAMPI (high speed measurement) and 6QM (IPv6 measurement) projects • contributions to standardization ( IETF  IPFIX and PSAMP working groups) • InterMon Paper at IPS workshop (bringing together IPFIX and PSAMP) • presentations at SCAMPI workshop (27.1.03, Amsterdam), 6QM meeting (7.3.03, Berlin), and TF-NGN meeting (7.02.03, Rome)

  10. Topology Detection Demonstration • is part of the overall INTERMON demo • shows integration of Topology Detection toolkit into the INTERMON system • local routing information collector watches routing updates (just like a router does) • routing information is encoded in XML and send to collection point (TD tool manager) • collected data can be viewed via GUI • more technically detailed slideshow next to the demo
