Re: [lmap] Missing concept from draft-eardley-lmap-terminology-01.txt

+1, Phil and Matt. I intended the reference path to be the basis for
discussions like this, especially when seeking equivalent points
in different access technologies.

<< I would like to have precise but technology independent terms for the boundary between shared and unshared access resources>>
This seems a nice idea to me

As you say, different technologies have the shared/unshared boundary at different distances from the customer. This means that great care is needed if comparing results to the "sharing point" in two different networks

I also agree that having a virtualised example would be good.

Ps think you're referring to http://tools.ietf.org/html/draft-morton-ippm-lmap-path-01 ? - though an open question whether any of the terms from there should be migrated into http://tools.ietf.org/html/draft-eardley-lmap-terminology-01 - might be nice to have them all in one place? Although organisationally one draft sits in ippm and the other in lmap

Thanks!

Most of the terminology in this draft defined by routing and addressing concepts.   For measurement, it is also important to have terminology to describe traffic aggregation.  Especially important is over which subpaths might one customer's traffic be subject to resource contention with other customers?

I would like to have precise but technology independent terms for the boundary between shared and unshared access resources.   Note that for many technologies (mobile service, DOCSIS) this is very close to the service demarc at the customer.  For others, such as FTTH and DSL it typically occurs in centralized location.

The measurement problems on either side of this boundary are extremely different, and we need to be able to unambiguously make this dichotomy.

I use "unshared access", "shared access", and "sharing point."   Note that for many technologies the sharing point is L2 or lower, so there might not a natural way to connect a MP at the sharing point.

There is also the risk that addressing and routing are going to become progressively less relevant as more and more of the network becomes virtualized through such technologies as software defined networks.    I consider ownership (responsibility), traffic aggregation and resource contention to be far more important than addressing.

Also, "Destination host" is a rather odd choice for a content provider.   Perhaps "core service provider."

Thank-you for all the comments!

(the draft is a possible starting point for terminology for the prospective lmap wg)

Best wishes
