Hi all,
I am new in ovs and really need your help.
I have a question about how ovs buffers a packet.
In OpenFlow protocol, if a packet does not match any rule in a flow table,
the packet will be buffered at the switch. The switch will then send a
packet-in message to an OpenFlow controller. The buffered packet will be
popped after a packet-in message (containing the id of that packet) is sent
back to the switch.
Does anyone know which part of the ovs code implement this packet buffering
function? I am using v1.9.3 and other versions are also welcome.
Thanks,
Best,
Xiaoye
