In other words, the BW reserved for a certain traffic will not be locked-in for that traffic only.

On the CE - PE link, we'll be setting the DSCP to EF (using the Priority Queue) for all of the Voice over IP and using WDRR (Weighted Deficit Round Robin) as a congestion avoidance mechanism.  We'd rather not use Traffic Engineering, but we will if we have to.  The issue we have is that we don't want to pre-allocate tunnels that may not be utilized.  This is the reason we're looking into the Automatic Bandwidth Adjustment.  Any reccomendations?
