Re: [CCAMP] Comments on draft-ietf-ccamp-lsp-attribute-ro-01

Hi Giovanni, answers inline

However, it may be interesting to differentiate between attributes that apply for a specific node, and attributes that apply to an LSP starting in a specific node.  The main use case is to describe with more detail both multi-domain and multi-layer paths. Currently, the LSP-ATTRIBUTES applies to the end-to-end LSP, but there is no way to express the LSP-ATTRIBUTES of the H-LSPs/FA-LSPS/S-LSPs in between.  In this case, the use of LSP-ATTRIBUTES will comply with the original purpose of the LSP-ATTRIBUTES.

Do you mean "partial"  (from and intermediate node to another intermediate node / eventually the end one) path attributes?

Yes, I meant specifying the attributes of a "segment" which starts and ends in intermediate nodes. This "segment" could potentially be for example an FA-LSP (this is just one example use case).


Adrian comment sounds like we are extending the semantic of LSP_ATTRIBUTE (hope my free written translation is correct). Does the above extend one step further?

Not expressing an opinion yet, just a clarification request.


I think this is a further use, so it may be a step further.


  Another comment, orthogonal to the previous one is to consider both LSP-ATTRIBUTES and LSP-REQUIRED-ATTRIBUTES.


I remember was already there but need to double check.
True.. just it was a bit hidden :-) Now I saw it.


Cheers
