Hi,

We have updated this document. It explains how a "logical" Network Service
Header can be achieved using MPLS labels and so leverage existing equipment
perhaps in advance of a full roll-out of NSH-capable equipment.

We think the work belongs in the MPLS working group (with cross-post to SFC).

If there is space on the MPLS agenda, it might be helpful to the WG for us to
present this.

Thanks,
Adrian

> Abstract:
>    Service Function Chaining (SFC) is the process of directing packets
>    through a network so that they can be acted on by an ordered set of
>    abstract service functions before being delivered to the intended
>    destination.  An architecture for SFC is defined in RFC7665.

>    The Network Service Header (NSH) can be inserted into packets to
>    steer them along a specific path to realize a Service Function Chain.
