/* Further pruned list of traffic classes for four-class system:
*
* Latency Sensitive (CS7, CS6, EF, VA, CS5, CS4)
* Streaming Media (AF4x, AF3x, CS3, AF2x, TOS4, CS2, TOS1)
* Best Effort (CS0, AF1x, TOS2, and those not specified)
* Background Traffic (CS1)
*
* Total 4 traffic classes.
as you said i will switch to CS3, then lets see!
but i think i should lower the connbyte number to a lower,cause my download speed is 1 mbps!
BTW: diffserv8 is not needed most of times?!
