Re: [mpls] Poll 1: ISD and PSD in the MNA Framework

[Yingzhen Qu <[e-mail]>]

Hi,

I agree that the framework document must be solution independent and a packet may carry ancillary data. As for ISD or PSD, I would think this should be discussed case by case, and the framework document should include pros and cons.

Thanks,
Yingzhen
