"diffserve8 is 5"? I don't understand. Do you mean 001000?
3.2. PHB configuration
Either a Class Selector (CS) PHB [RFC2474], an Experimental/Local Use
(EXP/LU) PHB [RFC2474], or an Assured Forwarding (AF) PHB [RFC2597]
may be used as the PHB for the LE traffic aggregate. This document
does not specify the exact DSCP to use inside a domain, but instead
specifies the necessary properties of the PHB selected by the DSCP.
If a CS PHB is used, Class Selector 1 (DSCP=001000) is suggested.
So CS1 is the original PHB for LE. However, it has problems and was never
really deployed and I was one who pushed for a specific codepoint within
000xxx for LE, that might have a chance to be deployed internet-wide.
000001 seems as good as any.
