EXP_MULT_05
===========

Objective: Test re-configuration to use a new path (change of locators) for UDP traffic using a proxy UDP application.

Experiment: Initiate a proxy UDP application with all the multihoming functionalities enabled. Create a simulated path failure (in the path used by the traffic of the application). Check that the traffic flow continues in the new path (packets can be captured to check new locators, application working again).

Result: Succeed

Setup: Four nodes participate in the experiment, One linux box (IP address 163.117.140.130) running a VLC (video) server, one OneLab box (onelab3 with two interfaces with addresses 163.117.140.132 and 163.117.140.165) running a proxy UDP within a sliver, another OneLab box (onelab5 with two interfaces with addresses 163.117.140.167 and 163.117.140.62) running a proxy UDP within a sliver, and another Linux box (IP address 163.117.140.131) running a VLC (video) client. The video is sent from the server to the client using the OneLab nodes as intermediate nodes by means of the UDP proxy software.

This file shows the captured traffic during the experiment. Coomunication starts with media going from 163.117.140.130 to 163.117.140.132, then from 163.117.140.132 to 163.117.140.167, and finally from 163.117.140.167 to 163.117.140.131. At second 13 a failure is detected in the path between 163.117.140.167 and 163.117.140.132 (the failure is unidirectional and only affects traffic in that direction), and REAP finds a new available path (163.117.140.165, 163.117.140.62). Traffic is moved to the new path after second 16, so traffic flows from 163.117.140.130 to 163.117.140.132, then from 163.117.140.165 to 163.117.140.62, and finally from 163.117.140.167 to 163.117.140.131.
