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,
Zhou Yu
