= High performance multicast
|
|
|
|
The OVN-Kubernetes network plugin supports multicast between pods on the default network. This is best used for low-bandwidth coordination or service discovery, and not high-bandwidth applications.
|
|
For applications such as streaming media, like Internet Protocol television (IPTV) and multipoint videoconferencing, you can utilize Single Root I/O Virtualization (SR-IOV) hardware to provide near-native performance.
|
|
|
|
When using additional SR-IOV interfaces for multicast:
|
|
|
|
* Multicast packages must be sent or received by a pod through the additional SR-IOV interface.
|
|
* The physical network which connects the SR-IOV interfaces decides the
|
|
multicast routing and topology, which is not controlled by {product-title}.
