CLP - Cell Loss Priority
A 1 bit field in the ATM cell header that determines whether or not a
given cell should be dropped by network equipment during periods of
congestion. This explicit loss priority can be set by the source node or the network. This field's values appear below.
- CLP=0
- Indicates that the cell should be treated with a high priority and should
not be dropped during periods of congestion.
- CLP=1
- Indicates that the cell should be treated with a low priority and
should be dropped, if needed, during periods of congestion.
This bit may be set by the network if a VC is violating its traffic contract. Cells being transmitted in excess of the peak cell rate researved on the VC will be marked by turning the CLP bit on.
