MPLS Recommendations
R-7. Separate ETS traffic treatment, both signaling and data, from other traffic treatment by the use of a dedicated MPLS DiffServ codepoint in E-LSPs and specify application of an ETS PHB
Preferred to alternative of dedicating LSPs to ETS, which increases operational complexity and reduces bandwidth available for other traffic even when not in use for ETS traffic
R-8. Use the same MPLS DiffServ codepoint for both National and International ETS traffic
Insufficient MPLS DiffServ codepoints available to assign separate codepoints to National and International ETS traffic
