[f-nsp] anyone using a serveriron to load balance rtsp

[Peter Clark]

Did you look at the obvious, like a speed/duplex mismatch between the
server and the switch port?  When we saw poor performance, it was
usually that or a lack of resources on the server.

	About four years ago, we were also in the streaming business.
We were very successful in load balancing rtsp for Real Networks, as
well as Windows Media streaming and Mac Quicktime.  I've included one of
the configs.  It was on the ServerIron XL platform.  The sticky option
is very important.  If you are not aware of it, you have to create
loopback interfaces on the real servers, using the virtual server IP
(the x.x.x, which were public IPs in this config) as the IP for the
loopback.  If you do this on Linux, make sure you've applied the ARP
modules or patches, depending on your kernel rev., or else the Linux
boxes will respond to ARPs for the VIPs.

		Chaps,
		
		I'm looking to implement a load shared rtsp video
steaming service ( Darwin streaming server on RLEL4)
		and wondered if anyone has already gone down this route.
		
		any inital play gets me connected to the server but the
video stream is awful
		Tried setting up my config to use DSR but didn't make
any difference
		
		Any input would be appreciated
