Hi all:
I got a weird problem when I'm using udpgen.click, below is my udpgen.click:
// UDPGen($device, $rate, $limit, $seth, $sip, $sport, $deth, $dip, $dport);
//
// $device name of device to generate traffic on
// $rate rate to generate traffic (packets/s)
// $limit total number of packets to send
// $size bytes per packet
// $seth source eth addr
// $sip source ip addr
// $sport source port
// $deth destination eth addr
// $dip destination ip addr
// $dport destination port
elementclass UDPGen {
$device, $rate, $limit, $size,
$seth, $sip, $sport, $deth, $dip, $dport |
source :: FastUDPSource($rate, $limit, $size, $seth, $sip, $sport,
$deth, $dip, $dport);
* //**pd :: PollDevice($device) -> ToHost;* //commented out
source -> td :: ToDevice($device);
}
// create a UDPGen
u :: UDPGen(eth1, 1800000, 8200000, 64,
00:e0:29:05:e2:d4, 2.0.0.2, 1234,
00:c0:95:e2:09:14, 1.0.0.2, 1234
and when I start it, I got messages as below:
*ToDevice eth1 is full, packet delayed*
and when I check the calls in todevice,it shows:
1172 packets held
0 packets dropped
92828616 hard start xmit
1212233322 device busy returns
92827444 packets sent
1214691606 calls to run_task()
92828656 pulls
The sending speed is only about 750Kpps, I remember before is around
1.7Mpps(I reformatted the disk and reinstall Linux). So what could be the
problem??Thanks very much for your help, I'll appreciate it.
Best
shule
