Can anybody tell me: is there any way(module, qdisc) which is possible to make a packet wait for a fixed time then dequeue? It is needed for me to get a fixed RTT. Using htb,tbf... I can get only total speed limitations but then a queue is empty rtt of small ICMP packets is smth like 200-300 usec. Will be thankful for any info.(Note: I`d like to make this thing using only Linux tc). Example: (speed is limited to 33.6 Kbit/sec using tbf as leaf node of one CBQ class) [root@rack1 root]# time scp root@10.10.10.65:/boot/vmlinuz-netli /tmp root@10.10.10.65's password: vmlinuz 100% |*************************************************| 907 KB 03:09 real 4m1.375s user 0m0.003s sys 0m0.012s [root@rack1 root]# ping 10.10.10.65 PING 10.10.10.65 (10.10.10.65) from 10.10.10.64 : 56(84) bytes of data. 64 bytes from 10.10.10.65: icmp_seq=0 ttl=254 time=354 usec 64 bytes from 10.10.10.65: icmp_seq=1 ttl=254 time=229 usec --- 10.10.10.65 ping statistics --- 2 packets transmitted, 2 packets received, 0% packet loss round-trip min/avg/max/mdev = 0.229/0.291/0.354/0.064 ms [root@rack1 root]# -- With Respect Dmitriy Kuznetsov _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
