Re: [CCAMP] FW: New Version Notification for draft-farrel-interconnected-te-info-exchange-03.txt

[Khuzema Pithewan <[e-mail]>]

Hi Adrian,

This draft lists all the possible (PCE, VNTM, L1VPN) mechanisms dealing with e-2-e path computation in multi-layer/multi-domain network configuration. It is a good thorough document that has everything that could be related to e-2-e te-path computation for multi-layer network.

We have 2 questions :

1. Since the document is marked as "Standard Track", does it mean that if it becomes RFC, the compliancy to this document will require supporting all the mechanisms?

2. Since this document is a summary of multiple mechanisms, should this be an "Informational draft", or are we missing something here that requires standardization?

Thanks
Khuzema, Rajan, Snigdho

All,

We continue to update this I-D to fill in the gaps.

In this case there are a couple more "applicability statements" showing how the architecture fits deployment models and the use cases in the problem statement part of the draft.

We remain interested in your review and comments.

Thanks,
Adrian

> Abstract:
>    In Traffic Engineered (TE) systems, it is sometimes desirable to
>    establish an end-to-end TE path with a set of constraints (such as
>    bandwidth) across one or more network from a source to a destination.
>    TE information is the data relating to nodes and TE links that is
>    used in the process of selecting a TE path.  The availability of TE
>    information is usually limited to within a network (such as an IGP
>    area) often referred to as a domain.
> 
>    In order to determine the potential to establish a TE path through a
>    series of connected networks, it is necessary to have available a
>    certain amount of TE information about each network.  This need not
>    be the full set of TE information available within each network, but
>    does need to express the potential of providing TE connectivity. This
>    subset of TE information is called TE reachability information.
> 
>    This document sets out the problem statement and architecture for the
>    exchange of TE information between interconnected TE networks in
>    support of end-to-end TE path establishment.  For reasons that are
>    explained in the document, this work is limited to simple TE
>    constraints and information that determine TE reachability.
