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.

Trone-aware Application (cont.) MH MeTHODICAL:
Coimbra, 16/03/2012
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.
Coimbra, 16/03/2012
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.
11
Trone-aware Application (cont.) MH NetManager:
Coimbra, 16/03/2012
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)
Coimbra, 16/03/2012
Description Status
Local Testbed
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.

DEMO B
Coimbra, 16/03/2012
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.
