[mpls] Re: Poll: IOAM and PSD

[Loa Andersson <[e-mail]>]

Haoyu,

While your response to the question and the first part of the second 
question is clear, I'm not clear what you mean by the second part of the 
response 2nd question.

    I’d like also see the support of application level ID and metadata to
    better support the application-aware networking.

Do you care to expand om this, are you referring to 
draft-song-apn-dns-application-aware-networking? Which IDs do you think 
need to support application-aware networking?

/Loa
