Why is this draft needed?
• To deploy DSTE, the domain administrator needs to perform several per-LSR, per-link and per-LSP configurations, as presented in draft-ietf-tewg-diff-te-proto-03.txt.– platform independent.
• Ensure that the TE-Class Map is configured in a uniform manner across all the participating DSTE LSRs.
When used with a NMS, a standardized DSTE-MIB can help the administrator to manage such DSTE domain wide configurations.
• Linkage to MPLS-TE MIB.

What does the draft support?
• Configuration/Monitoring supported:- Per-LSR configurations:
- Ability to configure the TE-Class Map - Per-Interface configurations:
- Ability to configure Bandwidth Constraints - Ability to configure Local Overbooking Multiplier - Ability to monitor the available bandwidth for each TE-Class
- Per-LSP configurations:- Ability to setup MPLS TE Tunnels with a specific CT - Ability to monitor the CTs being used by TE LSPs
- Special scenario configurations:- Ability to configure the DSTE-LSR in an hybrid environment - Ability to configure the DSTE LSR to behave like a TE LSR

BC Models supported:
– Not tightly coupled with any of the BC Models • Flexible to support new BC models in the future.
– Supports both RDM and MAM

Open Issues/Recommendation
• Which WG this draft belongs to?
– Reasons for including in MPLS-WG• The MIB presented in this draft extends the existing MPLS MIBs
defined by the MPLS-WG (to add support for DiffServ-aware MPLS TE).
– Reasons for including in TE-WG• The primary aim of the MIB is to support the TEWG document
“draft-ietf-tewg-diff-te-proto-03.txt”.
• TE Expertise present in the TE WG.
• Accept this document as a WG document.– Discussed on TE WG mailing list.
– Some changes made based on these discussions.

MIB Overview
1. TE-Class Map Table (mplsDsTeClassTable) • Allows user to define TE-Classes from Class-Types and Pre-emption priorities supported within
these Class-Types.
2. Bandwidth Constraint Table (mplsDsIfBCTable) • Allows user to define different bandwidth constraints on a per interfaces basis.• AUGMENTs mplsInterfaceConfTable defined in LSR-MIB
3. Local Overbooking Multiplier Table(mplsDsTeIfLOMTable)• Allows user to define the overbooking(and underbooking) factors for different Class-Types on a
per interface basis.• AUGMENTS mplsInterfaceConfTable defined in LSR-MIB
4. Unreserved Bandwidth Table(mplsDsTEIfUnresBwTable)• Allows user to monitor the unreserved bandwidth for different TE-Classes on a per interface
basis.
5. DSTE Tunnel Table(mplsDsTeTunTable)• Allows user to configure the class type associated with TE tunnels• AUGMENTS mplsTunnelTable defined in MPLS-TE-MIB
6. DSTE LSP Table(mplsDsTeLspTable) • Allows user to monitor DSTE related attributes associated with LSPs• AUGMENTs mplsXCTable defined in LSR-MIB

TBD
• Latest revision of DSTE-PROTO draft allows administrators to configure the BC Model on a per interface basis.
Need to update the MIB to allow such configuration.
• Need to update the NOTIFICATION section of the MIB.
• We may need to update the draft as and when new BC Models gets finalized by the WG.
