Cell Loss Priority (CLP) is a
flag bit
A bit field is a data structure that consists of one or more adjacent bits which have been allocated for specific purposes, so that any single bit or group of bits within the structure can be set or inspected. A bit field is most commonly used to r ...

being discarded if the network becomes congested. Cells where the CLP = 0 are ''insured'' traffic and unlikely to be dropped. Cells with CLP = 1 are ''best-effort traffic'', which may be discarded in congested conditions in order to free up resources to handle insured traffic.

network traffic Network traffic or data traffic is the amount of data moving across a network at a given point of time. Network data in computer networks is mostly encapsulated in network packets, which provide the load in the network. Network traffic is the main ...
"policing mechanism". Policing is a process that determines if the cells meet predefined restrictions as they enter an ATM network. These restrictions include traffic rates and "burst sizes" that are agreed upon by the customer and the network provider.
