Dear IS-IS, OSPF, MPLS, 6MAN Working Groups,

As you probably know, SPRING's work relates to your working group, as follows:

- IS-IS & OSPF: the draft defines the basis for your WG doc IGP extensions (draft-ietf-*-segment-routing-extensions)
- MPLS: MPLS is a data plane of SPRING. The SPRING architecture should not impact the MPLS data plane nor architecture, but does have side impacts. e.g. OAM, signaling (e.g. entropy label), deeper label stack.
- 6MAN: IPv6 is a proposed data plane of SPRING. It would require a new routing extension header to be defined in 6MAN. (+ security implications to be studied)

Thus, we anticipate you may have an interest in the SPRING architecture document. We are about to begin our working group last call and will cc your WGs. This message is to encourage you to review the document and comment as needed during the WGLC. Owing to the broad cc, out of respect for people's inbox clutter I suggest you respect the reply-to, which I've set to the SPRING mailing list, though if you think it's applicable feel free to add your own WG list. 

Thanks,

--Bruno and John
