Best Effort LSP's Bandwidth

Hi

I am wondering if in a network we are running CR-LDP TE (for traffic
having QoS requirements as well as BE traffic), how do we account for the
bandwidth used by best effort traffic while doing QoS path computation for
flows having QoS requirements.

 Do we consider bandwidth required by BE traffic as zero or we take
average bandwidth used by BE flows into account. If we account BE LSPs
having zero bandwidth then how accurate are the QoS path computations if
the BE flows account for a substantial portion of the network traffic.
