• DSCP: differentiated services codepoint

• CU: currently unused

• The recommended codepoint for the Default PHB is the bit pattern ’000000’

• The codepoint chosen for Default behavior is compatible with the existing practice (RFC-791)

• Where a codepoint is not mapped to a standardized or local use PHB, it SHOULD be mapped to the Default PHB
