This packs two separate routing-decision priorities into a single 8-bit value -- a 3-bit 'bumping priority', how likely this circuit is to displace a lower-priority circuit when resources are scarce, in the low bits, and a 4-bit bandwidth priority in the next bits -- giving the admin fine control over which circuits win resource contention during path computation, though it must be left at zero for ATM multipoint circuits. An admin needs to compute this value as a combined bitfield rather than a simple priority number. For example, a value encoding a bumping priority of 2 in the low bits and a bandwidth priority of 3 in the next bits gives this circuit meaningful precedence over lower-value circuits when the network needs to reroute around a failure.
