How can I implement following scenario?
I want my FreeBSD kernel to drop UDP packets on high load.
I can set sysctl net.inet.udp.recvspace to very low number to drop the packet. But how do I implement such an application?
I assume I would need some kind of client/server application.
Any pointers are appreciated.
p.s. This is not a homework. And I am not looking for exact code. I am just looking for ideas.
It will do that automatically. You don’t have to do anything about it at all, let alone fiddle with kernel parameters.
Most people posting about UDP are looking for ways to stop UDP from dropping packets!
