Greetings, Scenario: Centos box with eth1 (10.0.0.0/24) and eth0 (192.168.0.0/24) segment on eth0 has access to full bandwidth of uplink Both are on 100mbps switches Requirements: bandwith on segment on eth1 needs to be throttled to different speeds - say 32, 64, 128kbps and the such. Required for application performance testing purposes. As usual my girlfriend google is very verbose. (Sometimes I feel there should be utility like googlegrep or something :\ ) I am going through the excellent documentation from: http://linux-ip.net/articles/Traffic-Control-HOWTO LARTC.org Its all a bit too much for me to handle at this point in time and I am a bit pressed for time. Yes, havent worked much on tc / iproute2. In fact not much knowledge in networks in general. Any help appreciated.

It was created to test protocol designs then adapted for traffic management. However, I am not aware of any ports into Linux. <http://info.iet.unipi.it/~luigi/dummynet/> <http://cs.baylor.edu/~donahoo/tools/dummy/tutorial.htm> Bob McConnell N2SPP
