Hi, I wonder about the performance of a Linux box used as router (I guest I''m not the first :). Althought I know it mainly depends on the hardware, I''m trying to find some references on the topic or comparations with other routing solutions (FreeBSD box used as router, Cisco, etc). For example, http://facweb.cti.depaul.edu/jyu/Publications/Yu-Linux-TSM2004.pdf (althought is

Hi there! I am working a lot with VoIP in my company, so I thought to use linux bridge functionality together with tc to emulate delay, jitter, packet loss, duplication, reordering etc. for testing purposes in our lab against our VoIP products. I just recognized, that a basic bridge just with it''s minumum configuration of 2 network interfaces creates latency of approx. 5ms on very low

Hi, the nbdkit python plugin example has suboptimal memory management: - it creates the disk image as a string on init - it casts the string to bytearray on every read - it copies the string before and the string after the written region, then reassembles those pieces together with the written region to a new disk image string This is not a problem as long as the image is small, but in my tests

Hi, I am trying to setup a shaper for my linux box and I am experiencing some problems. What I am trying to do is priorizing packets on the egress link, therefore I have setup some prio classes etc. The priorizing seem to work but the problem is that the ceil parameter doesnt seem to work on non leafs. This is what stats show: > class htb 1:1 root rate 3000bit ceil 3000bit burst 1602b/8 mpu
