Re: [Idr] WG adoption call for draft-xu-idr-performance-routing-01

[<[e-mail]>]

Hi Stephane,

Good point!

FWIW, we have investigated this issue in a specification that is more generic than what we are doing in draft-xu-idr-performance-routing:
 https://tools.ietf.org/html/draft-boucadair-qos-bgp-spec-01#page-16 (Search for "QoS hole" in that document)

This point is worth to be documented in the next revision of draft-xu-idr-performance-routing.

Cheers,
Med

Hi,

I'm wondering what happens if a specific BGP Speaker in the path vector is supporting this extension but for some (many) reason, cannot provide a latency information.
In this case, there must be an information encoded saying that the NETWORK_LATENCY cannot be used for this specific path because part of the latency will be missing. For example, we can set the value to the worst value  (like a MED missing as worst ? :) ).


Best regards,

Stephane
