Introduction Trone-Aware application

Current Status Tests

Conclusion

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.

Description Status Local Tested PT CloudMultiple Attribute Decision Mechanism (MADM)*

Yes In 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.) MH OWAMP:

It was developed also a framework to enable collecting these metrics for a long monitoring period.

Description Status Local Testbed PT CloudCollect Network Performance Metrics per need (e.g., event-based)

Yes Yes With End-to-End connectivity

issues! (SOLVED TODAY)

* Metrics include One-way delay, jitter, packet loss, reordering flag, duplicates flag, Hops.

Description Status

Local Testb

ed

PT Cloud

Monitor interface specific info and events (e.g., up, down). Support for wireless and wired interfaces.

Yes Yes Yes

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)

PT Cloud

Framework to change attributes of Ethernet interfaces that are “too static”!

Yes Yes Only IP route2

dynamics

13

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

Coimbra, 16/03/2012

Description Status

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.) MH FIT input data to Trone-aware

application:

Coimbra, 16/03/2012

Data Default 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, 16/03/2012

Next-Steps Continue testing. Stabilize current version of development. Specify MH FIT and SCTP Resource Manager

DEMO A

Coimbra, 16/03/2012

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.
