6# This script evaluates the AMT driver.
7# There are four network-namespaces, LISTENER, SOURCE, GATEWAY, RELAY.
8# The role of LISTENER is to listen multicast traffic.
9# In order to do that, it send IGMP group join message.
10# The role of SOURCE is to send multicast traffic to listener.
11# The role of GATEWAY is to work Gateway role of AMT interface.
12# The role of RELAY is to work Relay role of AMT interface.
