sdpBandwidthBookingFactor is used to calculate the max
SDP available bandwidth. The value of
sdpBandwidthBookingFactor specifies the percentage of the
SDP max available bandwidth for VLL call admission. When
the value of sdpBandwidthBookingFactor is set to zero (0),
no new VLL spoke-sdp bindings with non-zero bandwidth are
permitted with this SDP. Overbooking, >100% is allowed.
