Hello, I havtwo apps communicating over UDP on thsame host and I would like to send packets with varying delays (jitter) buno ouof order packets. app1 ---> loopback ----> app2 I havthis rulfor loopback interface: sudo tc qdisc add dev lo roohandl1: netem delay 10ms 100ms This seems to creatthjitter successfully; however, there are out of order packets.. Basically I would likto receivthe packets on the receiver (app2) sidin thorder that they are sent from the sender (app1), with jusvarying delay, i.e. with jitter. I tried sombasic reorder commands.. when I usreorder 100%, it does the reorder butheris no jitter in this case. If I use reorder command with anything less tha100%, then theris out of order packets. Isays here<http://www.linuxfoundation.org/collaborate/workgroups/networking/netem#How_to_reorder_packets_based_on_jitter.3F> that if executthfollowing command, the packets will stay in order: sudo tc qdisc add dev lo paren1:1 pfifo limi1000 BuI still geout of order packets with the above command executed after thfirscommand. Any help is much appreciated. Thanks! -------------- nexpar-------------- AHTML attachmenwas scrubbed...
