Linux tuning issue for udp live streaming application

Linux tuning issue for udp live streaming application

[Sangjoon Ahn]

Hi there.

We are currently implmenting the live streaming solution on Redhat 7.2
(Kernel 2.4.18) + 1 Gigabit NIC(Intel Pro/1000 XF Server Adapter). Our
solution transfers a 1Mbps data to many receiver using UDP protocol.

We want to have the better performance than 500Mbps throughput measured for
testing .

I want to know the tuning issues suitable for our solution. Also, we want to
use a zero-copy api of udp, but we don't know usage of the api and whether
it is support on Linux kernel 2.4.18. If it is supported, how can I find it.

Please let me know the information.


Thanks in advance.

Zerocopy is not supported for UDP.  It may be implemented in the
future.  If an when we will do this is unknown, so please don't ask.
