Standards
Standardization of DiffServ-aware MPLS Traffic Engineering is still in progress in the IETF (Internet
Engineering Task Force). At the time of publication of this feature guide, DS-TE is documented in the
following IETF drafts:

following IETF drafts:

As the IETF work is still in progress, details are still under definition and subject to change, so DS-TE
should be considered as a pre-standard implementation of IETF DiffServ-aware MPLS Traffic
Engineering. However, it is in line with the requirements described in the first document above. The
concept of "Class-Type" defined in that IETF draft corresponds to the concept of bandwidth pool
implemented by DS-TE. And because DS-TE supports two bandwidth pools (global pool and sub-pool),
DS-TE should be seen as supporting two Class-Types (Class-Type 0 and Class-Type 1).
