[netperf-talk] bidirectional transfer with SCTP_RR

[Frank Schuster]

Hello,

I have a question to the bidirectional transfer test with SCTP_RR and the burst (-b) option.
I tried first the bidirectional test with TCP_RR from the manual page and it works succesful.
The output is shown:
netperf -t TCP_RR -H 192.168.1.101 -- -b 6 -r 32K -s 256K -S 256K
TCP REQUEST/RESPONSE TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.101 (192.168.1.101) port 0 AF_INET : first burst 6
Local /Remote
Socket Size   Request  Resp.   Elapsed  Trans.
Send   Recv   Size     Size    Time     Rate         
bytes  Bytes  bytes    bytes   secs.    per sec   

225280 225280 32768    32768   10.00     345.59   
225280 225280

But then I thought I can do the same with SCTP_RR but netperf says: Invalid option "-b"
netperf -t SCTP_RR -H 192.168.1.101 -- -b 6 -r 32K -s 256K -S 256K
netperf: invalid option -- 'b'
SCTP REQUEST/RESPONSE TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.1.101 (192.168.1.101) port 0 AF_INET : first burst 0
Local /Remote
Socket Size   Request  Resp.   Elapsed  Trans.
Send   Recv   Size     Size    Time     Rate         
bytes  Bytes  bytes    bytes   secs.    per sec   

225280 225280 32768    32768   10.00     125.50   
225280 225280

So I have to question about this.
1.) What really means the option -b in the test specific option?
2.) How can I do a SCTP bidirectional test?

Regards
Frank
