Shahram,

This draft is ONLY intended to provide a MPLS-over-IP encapsulation method with a better load-balancing applicability so far to those operators who happen to require transporting MPLS application traffic across IP networks. I believe MPLS-based VPN over IP, NVGRE and VXLAN each have their own advocators and use cases. If you absolutely believe it's meaningless of transporting MPLS application traffic across IP networks and therefore those existing RFCs related to MPLS over IP tunneling mechanisms should be moved to Historic status, please say so.

By the way, it seems this (http://www.ietf.org/mail-archive/web/nvo3/current/msg01864.html) is just the right thread suitable for you to make the following argument (i.e., whether or not MPLS-based VPN is applicable to data centers). I had thought you would speak up at that time. Sadly, surprisingly silent till now. 

Sigh, I didn't intend to say the above otherwise. 

Xiaohu
