Re: Multicast Routing Performance

2003-06-04 Thread Gavin Kenny
Ahh! I am doing some testing of multicast video
streaming. It streams a single 8Mbps stream fine but
if I add another to it the throughput just falls away
for both streams.

Am I asking too much to stream approx 16Mbps? I kinda
thought that 100Mbps NICs and a PIII would handle it.
I don't suppose there are any settings I can tweak?

cheers

We have been doing that for years.

But don't expect too much speed with a PIII 800, we usually have
something like 10Mbps brust traffic.

I can say that your hardware can perform up to wire's maximum capacity.
Maybe it depends on what else other than routing services you have to
run on that machine, but I don't think that would be a problem.

Ciao ciao

Multicast Routing Performance

2003-06-03 Thread Gavin Kenny
Does any one have any experience of using a FreeBSD
Box as a multicast router?

I have a PIII 800Mhz with two 100Mbps NICS, what kind
of throughput can I expect to get out of this setup?

please can you cc [EMAIL PROTECTED]
