Thu Apr 13 08:03:00 PDT 2006

Do you think this new code will be part of the next IBED RC?

	Hi,

	There is no point to check SDP now. We released that the SDP
code in OF is not good enough, not stable and has many races. Michael
Tsirkin is recoding some parts of it. We anticipate that within 2 weeks
the code will stabilize and we'll post it. 

	Regards,
	   Aviram

	When these kinds of problems happen to me, I start by debugging
with strace, to make sure both netserver and netperf are using SDP.

		Hi

		Yes, netserver was restarted with libsdp. I didn't get
any error there.
		I face same issue even if i use the default config
(libsdp.conf) . Netserver was started using default libsdp.conf.
		For netperf, initially i used default libsdp.conf file
but when it didn't worked i changed it as mentioned in my previous mail.

		Attached below is the output from netserver machine.

		Thanks

			Did you restart netserver w/libsdp, too?

			What happens when you use libsdp.so with the
default libsdp.conf config?

				Hi: 

				I am trying to measure SDP throughput
using netperf. But as soon as i enable SDP for netperf, my netperf is
not able to establish a connection. In my libsdp.conf file, i have
included following

				match destination 172.26.16.44/24 
				match listen * 
				match program * 

				Please let me know if i missed out
something. 

				Attached below is the output. Initially
without SDP, netperf was working fine. Then I enabled sdp and after that
my netperf doesn't work.

				Thanks 
				Karun
