This review is effectively an extension of aprior TSVART review of earlier versions of three related DLRP drafts to include a fourth DLEP draft.

That prior TSVART review (https://mailarchive.ietf.org/arch/msg/tsv-art/JOflH810WxMl8U5tXnVVTOCwgLE/) covered:

        DLEP Credit-Based Flow Control Messages and Data Items
                draft-ietf-manet-dlep-credit-flow-control-09
        DLEP DiffServ Aware Credit Window Extension
                draft-ietf-manet-dlep-da-credit-extension-12
        DLEP Traffic Classification Data Item
                draft-ietf-manet-dlep-traffic-classification-06

The additional fourth draft that is the subject of this review is:

        DLEP IEEE 802.1Q Aware Credit Window Extension
                draft-ietf-manet-dlep-ether-credit-extension-02

This ether-credit-extension draft has strong similarities to the da-credit-extension draft, so the prior review comments applicable to the da-credit-extension draft should also be applied to this ether-credit-extension draft.  Most of the prior review comments were on the credit-flow-control and traffic-classification drafts, although there are a few that apply to the credit-extension drafts, e.g., the security concern for which a resolution was discussed on the mailing list.

The review request specifically mentioned the number of documents concern raised by the prior review.  It is clear from the shepherd writeups for the previously reviewed drafts that the WG has discussed whether to merge drafts and has decided not to merge any of them, beyond which the addition of this fourth draft weakens the rationale for merging.  That seems reasonable - this reviewer will nowdefer to the judgement of the WG and the responsible ADs on the number of drafts that are appropriate.
