  1. The case for an Open and Scalable Internet Measurements Service • Benoit Donnet, Olivier Bonaventure • Université Catholique de Louvain (Belgium) • NeXtworking Workshop - April 2007

  2. Evolution of expectations

  3. Servers are evolving

  4. Networks are evolving • Increasing interest in multihoming • At least 60% of the stub domains are multihomed ([Agarwal03])

  5. Quality of Service • Yesterday QoS problem was • How to find a QoS path between A & B? • Today, QoS problem becomes • Among B1, B2, ..., Bn, how to maximise the QoS perceived by A by contacting one or a few Bi?

  6. How to solve the QoS problem? • Each application contains its own set of measurements and heuristics • Inefficient • Non scalable

  7. Can we do better? • IETF’s IPPM WG • Standardized methods to collect accurate measurements • What’s missing? • An Open & Scalable Measurements Service (OSIMS) that can be used by any application

  8. OSIMS

  9. OSIMS (2) • Continuous service • Always on infrastructure type service • Provides an API that can be queried by applications to obtain predictions/measurements on • Delay • Bandwidth • Topology • Geolocation

  10. Research Challenges • How to efficiently perform measurements? • avoid redundancy • avoid burdening the network • How to ensure security/reliability? • limit the risk of attack/disturbance • How to query data? • scattered among participants
