[CCAMP] Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) Path Diversity using Exclude Routes

[John E Drake <[e-mail]>]

HI,

I was reading:   http://datatracker.ietf.org/doc/draft-ietf-ccamp-lsp-diversity/?include_text=1, and I happened to notice the following paragraph:

"The means by which the node calculating or expanding the route of the signaled LSP discovers the route of the path(s) from which the signaled LSP
 requires diversity are beyond the scope of this document. "

Doesn't this disclaimer effectively render this draft useless?  The draft also does not define how the node that initially signaled the LSP finds the 'node calculating
or expanding the route'  nor how it delivers the signaled LSP request to that node.

As an aside, the draft:  http://datatracker.ietf.org/doc/draft-ali-ccamp-rsvp-te-include-route/?include_text=1 would be subject to the same criticism
except that the above quoted paragraph is replaced with:

"The above-mentioned use cases require relevant path inclusion requirements to be communicated to the route expanding nodes.  This document addresses
 these requirements and defines procedures to address them." 

Even though this is helpful, the draft doesn't actually define these procedures.

Yours Irrespectively,

John
