Hi everyone:

	A traffic storm occurs when broadcast, unknown unicast, or multicast (BUM) packets flood the LAN, creating excessive traffic and degrading network performance. 
So physical switch or router offer traffic storm protection, these approaches:
	1.Storm suppression, which enables to limit the size of monitored traffic passing through an Ethernet interface by setting a traffic threshold. 
When the traffic threshold is exceeded, the interface discards all exceeding traffic.
	2.Storm control, which enables to shut down Ethernet interfaces or block traffic when monitored traffic exceeds the traffic threshold. It also enables an interface to send trap or log messages when monitored traffic reaches a certain traffic threshold, depending on the configuration.
	I want to get traffic storm protection in network virtualization environment as same as in physical network. So I registered a BP:  https://blueprints.launchpad.net/neutron/+spec/traffic-protection  and
wrote a Wiki: https://wiki.openstack.org/wiki/Neutron/TrafficProtection

	I would like your opinions about this subject. Specifically, how to avoid traffic storm and protect traffic in network virtualization environment ? Is there other approaches?
Welcome to share your experiences about it .

Thanks,
