Subject: [spring] request to reconsider the new version of draft-xu-sfc-using-mpls-spring

Hi SFC co-chairs,

I have remove those options (i.e., encoding SFC using a label stack consist of global labels and inserting a protocol field after the label stack for MPLS payload indication) which would cause changes to the MPLS architecture in the latest version (http://tools.ietf.org/html/draft-xu-sfc-using-mpls-spring-03). 

Therefore, we co-authors think it's now becoming suitable for the SFC WG to reconsider this simplified MPLS-SPRING-based SFC solution which doesn't require any change to the MPLS base architecture.

Best regards,
Xiaohu
