Andreas Kock, Research & Development 4 Objectives Scalable inter-domain QoS analysis architecture for large interconnected Internet domains Integration of monitoring, modelling, structure mapping, simulation, optimization and visual datamining components using a distributed database

Andreas Kock, Research & Development 5 Functional components

Andreas Kock, Research & Development 6 Distributed measurement

Andreas Kock, Research & Development 7 Measurement information

Andreas Kock, Research & Development 8 Fields of application Traffic modelling for capacity planning Peering interconnectivity study Best value connectivity Net structure exploration Event detection

Andreas Kock, Research & Development 9 Application QoS over multiple domains ISP End user ISP End user DB { INTERMON-Database DB

Andreas Kock, Research & Development 10 ISP border router traffic measurement/modelling ISP DB { INTERMON-Database

Andreas Kock, Research & Development 11 Example - Traffic modelling Dynamic of the total input/output traffic Activity of the total input/output traffic Topological analysis of traffic

Andreas Kock, Research & Development 12 Simulation for large European testbeds study the behaviour of different strategies for user traffic engineering with respect to inter-domain models application traffic models border router traffic models inter-domain topology.

Andreas Kock, Research & Development 13 Simulation goal discover optimization rules for assigning traffic to inter-domain routes considering MPLS/DiffServ interfaces

Andreas Kock, Research & Development 14 Simulation For the GEANT testbed, simulation should show different strategies for the assignment of application traffic to MPLS/DiffServ classes the assignment of AS traffic to MPLS/DiffServ classes keeping QoS in case of fall back situations, if a border router has a malfunction keeping QoS if an AS changes its routing policy.

Andreas Kock, Research & Development 15 Future activities Currently: Specification phase Planning experimental use for European testbeds First prototype in spring of 2003 International workshop on inter-domain performance and simulation planned for February 2003 visit
