1 16 March 2012 Coimbra, PT Trone-Aware Application Bruno Sousa LCT - Centro de Informática e Sistemas Universidade de Coimbra

2 Summary 2 Coimbra, 16/03/2012  Introduction  Trone-Aware application  Current Status  Tests  Conclusion

3 Introduction / Goals 3  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. Coimbra, 16/03/2012

4 Trone-aware Application Architecture 4 Coimbra, 16/03/2012

5 Trone-aware Application internals 5 Coimbra, 16/03/2012

6 Trone-aware Application (cont.) 6  SCTP API functionalities: Coimbra, 16/03/2012 DescriptionStatusLocal Testbed PT Cloud Configure SCTP Channel (e.g, clocking mode) Yes To Be Started Get SCTP Options (e.g, size of sender buffer) Yes To Be Started Set SCTP OptionsIn Tests To be started in upcoming weeks. Configure Primary Address of Association In Tests Shutdown association for non trust IP To Be developed

7 Trone-aware Application (cont.) 7  SCTP API Events: Coimbra, 16/03/2012 DescriptionStatusLocal TestbedPT Cloud AssociationChangeNotificationYes To be started in upcoming weeks. PeerAddressChangeNotificationYes SendFailedNotificationYes ShutdownNotificationYes

8 Trone-aware Application (cont.) 8  MH Shim Layer: Coimbra, 16/03/2012 DescriptionStatusLocal Tested PT Cloud Support VoIPYes Support Data*In DevelopmentIn TestsTo be started in upcoming weeks. Identification of application characteristics In DevelopmentIn Tests * Using Apache Commons Net

9 Trone-aware Application (cont.) 9  MH MeTHODICAL: Coimbra, 16/03/2012 DescriptionStatusLocal TestedPT Cloud Multiple Attribute Decision Mechanism (MADM)* YesIn local testbed; And tested for two papers. To be started in upcoming weeks. * Using Rserve to make the interface to a script in project R.

10 Trone-aware Application (cont.) 10  MH OWAMP:  It was developed also a framework to enable collecting these metrics for a long monitoring period. Coimbra, 16/03/2012 DescriptionStatusLocal TestbedPT Cloud Collect Network Performance Metrics per need (e.g., event-based) Yes With End-to-End connectivity issues! (SOLVED TODAY) * Metrics include One-way delay, jitter, packet loss, reordering flag, duplicates flag, Hops.

11 Trone-aware Application (cont.) 11  MH NetManager: Coimbra, 16/03/2012 DescriptionStatusLocal Testbed PT Cloud Monitor interface specific info and events (e.g., up, down). Support for wireless and wired interfaces. Yes

12 Trone-aware Application (cont.) 12  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) Coimbra, 16/03/2012 DescriptionStatusLocal TestbedPT Cloud Framework to change attributes of Ethernet interfaces that are “too static”! Yes Only IP route2 dynamics

13 Trone-aware Application (cont.) 13  MH FIT to be specified: Coimbra, 16/03/2012 DescriptionStatus Interface type (REST, Web-service) Data we need and can use for SCTP (see next slide) Data we can provide to FIT

14 Trone-aware Application (cont.) 14  MH FIT input data to Trone-aware application: Coimbra, 16/03/2012 DataDefault Value Notes Monetary of other type of cost of an interface (COST). 0€Can not be provided by FIT. Trust of an IP address (TRUST)Should be provided by FIT to augment security at transport layer ANY SUGGESTION?!

15 Conclusion Coimbra, 16/03/  Next-Steps  Continue testing.  Stabilize current version of development.  Specify MH FIT and SCTP Resource Manager

16 End 16 Thank You Coimbra, 16/03/2012

17 DEMO A Coimbra, 16/03/  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 Coimbra, 16/03/  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 Coimbra, 16/03/  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.
