[LARTC] Question2: can an mpu be specified using htb by appending an tc-tbf queue?

Hello! tc-htb is great because its easy, but you cannot specify an mpu. Thats bad, because with the mpu you can specify the physical characteristics of the underlying connection. I have a braodband dsl-connection. I have the problem that the proportion of small packets to big packets changes a lot.

RE: [LARTC] Very simple traffic shaping script for H.323

Yup, Andy is right. This is traffic to/from the Internet. After brooding all day about this, my simple scheme to set TOS bits and let nature take its course had major holes: (1) Other apps could set the same TOS bits to any value they want, and those apps would slog it out with my H.323 stuff. S

RE: [LARTC] Very simple traffic shaping script for H.323

I may have the answer to my own questions: (1) When the value for the DSCP field for EF (Expedited Flow) is hex 2E, why does tcpdump display it as hex B8? I think there's some bit shifting going on. The DSCP field is the left most 6 bits of the DS octet in the packet header. 2E is 0010 1110.

Maybe my idea from the other day isn't so simple. When I run tcpdump and watch my h.323 packet stream, tcpdump shows a stream that looks like this: . . . 09:16:09.031943 abc.def.ghi.jkl.3230 > mno.pqr.stu.vwx.3230: udp 92 [tos 0xb8] 09:16:09.048128 mno.pqr.stu.vwx.3230 > abc.def.ghi.jkl.3230: udp
