
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.

MH OWAMP:
Description
Status
Local Testbed
PT Cloud
Collect Network
Performance Metrics
per need (e.g.,
event-based)
Yes
Yes
With End-to-End
connectivity issues!
(SOLVED TODAY)
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.


MH FIT input data to Trone-aware application:
Data
Monetary of other type of
cost of an interface (COST).
Trust of an IP address (TRUST)
Default
Value
Notes
0€
Can not be provided by
FIT.
Should be provided by
FIT to augment security
at transport layer
ANY SUGGESTION?!

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


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.
