Presentation Transcript

  1. Trone-Aware Application • Bruno Sousa (bmsousa@dei.uc.pt) • LCT - Centro de Informática e Sistemas • Universidade de Coimbra • 16 March 2012Coimbra, PT

  2. Summary • Introduction • Trone-Aware application • Current Status • Tests • Conclusion

  3. Introduction / Goals • Resilience is a key goal of Multihoming. • Detect network failures and react proactively. • Detect changes in network condictions (e.g., more delay) and react proactively.

  4. Trone-aware Application Architecture

  5. Trone-aware Application internals

  6. Trone-aware Application (cont.) • SCTP API functionalities:

  7. Trone-aware Application (cont.) • SCTP API Events:

  8. Trone-aware Application (cont.) • MH Shim Layer: * Using Apache Commons Net

  9. Trone-aware Application (cont.) • MH MeTHODICAL: * Using Rserve to make the interface to a script in project R.

  10. Trone-aware Application (cont.) • MH OWAMP: • It was developed also a framework to enable collecting these metrics for a long monitoring period. * Metrics include One-way delay, jitter, packet loss, reordering flag, duplicates flag, Hops.

  11. Trone-aware Application (cont.) • MH NetManager:

  12. Trone-aware Application (cont.) • Introducing dynamics in the Ethernet interfaces of PT Cloud (events for MH NetManager): • Dynamics include: • Change of media type (using mii-tool) • Change of delay and packet loss (using ip route2 tools)

  13. Trone-aware Application (cont.) • MH FIT to be specified:

  14. Trone-aware Application (cont.) • MH FIT input data to Trone-aware application:

  15. Conclusion • Next-Steps • Continue testing. • Stabilize current version of development. • Specify MH FITand SCTP Resource Manager

  16. End Thank You

  17. DEMO A • Goals: • Demonstrate that TRONE enhances security! • Steps: • Step 1: Demonstrate Standard SCTP behaviour. • Step 2: Introduce failures at network and trust info from FIT. • Step 3: Demonstrate SCTP behaviour with input data of FIT.

  18. DEMO A – with End-node outside Cloud • Goals: • Demonstrate that TRONE enhances security! • Steps: • Step 1: Demonstrate Standard SCTP behaviour. • Step 2: Introduce failures at network and trust info from FIT. • Step 3: Demonstrate SCTP behaviour with input data of FIT.

  19. DEMO B • Goals: • Demonstrate that path selection of SCTP can be enhanced ! • Steps: • Step 1: Demonstrate Standard SCTP behaviour. • Step 2: Introduce failures at network. • Step 3: Demonstrate SCTP behaviour with input data of monitoring.
