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