how to do probabilistic packet loss in kernel?
Hi, I am using iproute2 to setup fowarding, adding routes like "ip route add 192.168.1.3 via 192.168.1.2" I was wondering where in the kernel I can insert probabilistic packet loss only for forwarded packets? So that for instance I can drop 5% of all forwarded packets? I don''t need help with the actual code, just need help finding where to insert this code :) Thanks! George

Sluggish throughput with htb
...l 486kbit tc qdisc add dev eth0 parent 1:1 handle 10: sfq perturb 10 However, after recently updating to kernel version 2.6.15, throughput on eth0 has become sluggish and it is only by disabling the above that performance is restored. Also, I see a whole slew of the following messages in my log: qdisc_restart: Empty queue has non zero length 1 Any advice on how to approach this problem would be greatly appreciated. Thanks, - Andrew Kraslavsky P.S. If I go back to my 2.4.20 kernel, throughput is restored. _________________________________________________________________ Help yourself to FREE treats...

netem with prio hangs on duplicate
hi i tried the example given on the examples page to duplicate selected traffic like tc qdisc add dev eth0 root handle 1: prio tc qdisc add dev eth0 parent 1:3 handle 3: netem duplicate 40% tc filter add dev eth0 protocol ip parent 1:0 prio 3 u32 match ip dst 11.0.2.2 flowid 1:3 when i ping from 11.0.2.2 to this interface my machine hangs. the same thing works for drop or delay. i would

[PATCH] (3/4) delay scheduler race with device stopped
The delay scheduler dequeue routine has some code cut&pasted from the TBF scheduler that caused a race with E1000 when ring got full. It looks like net schedulers should never be calling netif_queue_stopped because the queue may get unstopped by interrrupt or receive soft irq (NAPI) which races with the dequeue in the transmit scheduler. Also, if requeuing the packet fails, it is probably

xenbus api
Hello I have a lot of problem using the xenbus api (in xen-3.0-testing). I had to modify the network backend driver (file netback.c), and each call to a xenbus function in a virtual machine make my machine reboot (not the virtual, the real machine). for example, I ''ve add this line of code (wich is useless):

[RFC] [ver3 PATCH 0/6] Implement multiqueue virtio-net
This patch series resurrects the earlier multiple TX/RX queues functionality for virtio_net, and addresses the issues pointed out. It also includes an API to share irq's, f.e. amongst the TX vqs. I plan to run TCP/UDP STREAM and RR tests for local->host and local->remote, and send the results in the next couple of days. patch #1: Introduce VIRTIO_NET_F_MULTIQUEUE patch #2: Move

New IMQ device implementation supporting device EOS
Hello All Its first time i posting to this mail list :). I have done something (maybe) important. I write new IMQ device driver based from Martin Devera and Patrick McHardy implementation with device EOS support. My current implementation supporting only egress trafic shaping and kernel 2.4.25. For more details, source and examples have look at my page http://hyperfighter.jinak.cz/qos Ill

Dual T400P, SMP, performance issues
Hi, We are trying to validate Asterisk as a media gateway PRI <-> SIP with two T400P (8 T1s) per box. The first experience with BOX1 (Compaq, 2.53 GHz, 1 Gb RAM) and just one T400P was encouraging - on the load test with 3 T1s worth of calls we had on average 75% idle CPU. Not so with BOX2 (Dell, single 2.6 GHz Xeon, 1 Gb RAM, 2 T400P) and BOX3 (Dell, dual 2.6 GHz Xeon, 2 Gb RAM, 2 T400P,
