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

Mon Oct 10 16:58:32 EDT 2005

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
	alex
