The following is the description of this field This will be used in conjunction with the service type field to get the correct traffic behaviour. In the conformances the the 0 or 0plus1 refers to the clp bit in the cells. If 0plus1 is the bucket reference then the clp bit is ignored. If 0 is specified for the bucket then check only clp=0 cells. 1: Best Effort will try to send all cellsin a best effort way. This will follow the Aqueman Algorithm 2: one-bucket-notag-0plus1 will use 1 bucket i.e is the PCR(0+1) bucket and drop all cells in excess. 3: two-bucket-notag-0plus1-0plus1 uses 2 buckets. The 2 buckets are pcr(0+1) and scr(0+1). All cells conforming to both buckets will be passed through. The rest will be dropped. 4: two-bucket-notag-0plus1-0 uses 2 buckets. The 2 buckets are pcr(0+1) and scr(0) or pcr(0). Cells which conform to both buckets are passed through. The rest are dropped. 5: two-bucket-tag-0plus1-0 uses 2 buckets. The 2 buckets are pcr(0+1) and scr(0) or pcr(0). Cells which do not conform to the first bucket are dropped. Cells which do not conform to the 2nd bucket are tagged. 6: best-effort-tag. Tag all cells and then do a best effort.
