EXP_MULT_03
===========

Objective: Test exploration of alternative paths, and selection of a working path.

Experiment: Initiate an application (UDP echo application) with all the multihoming functionalities enabled. Create a simulated path failure (in the path used by the traffic of the application). Check that REAP explores new paths (probe messages can be used to detect this) and chooses a working one.

Result: Succeed

Setup: Two Onelab nodes involved, one with two interfaces with addresses 163.117.140.132 and 163.117.140.165 (onelab3) and the other with two interfaces with addresses 163.117.140.167 and 163.117.140.62 (onelab5).

Wireshark file of the traffic sniffered during the experiment. Only one side of the data traffic is shown. Initially a path defined by IP addresses (163.117.140.167, 163.117.140.132) is used. A failure command is issued after second 82 of the experiment. At second 85 REAP has detected the failure and starts sending probe messages through different paths (defined by  different source and destination IP addresses) to find a working path. REAP messages are sent as an UDP application using source and destination UDP port 12345. After finding a new path defined by IP addresses (163.117.140.62, 163.117.140.165), the multihoming component moves the application to the new path (traffic flows again in the new path after second 86).
