MPLS Segment Routing in IP Networks
Also known as "MPLS-SR-over-UDP"

Thanks for useful discussion on and off list since Prague and especially to Jeff
Tantsura who supplied a good chunk of text and suggestions.

More discussion encouraged.

Cheers,
Adrian

> Abstract:
>    Segment routing is a source routed forwarding method that allows
>    packets to be steered through a network on paths other than the
>    shortest path derived from the routing protocol.  The approach uses
>    information encoded in the packet header to partially or completely
>    specify the route the packet takes through the network, and does not
>    make use of a signaling protocol to pre-install paths in the network.
> 
>    Two different encapsulations have been defined to enable segment
>    routing in an MPLS network or in an IPv6 network.  While
>    acknowledging that there is a strong need to support segment routing
>    in both environments, this document defines a mechanism to carry MPLS
>    segment routing packets encapsulated in UDP.  The resulting approach
>    is applicable to both IPv4 and IPv6 networks without the need for any
>    changes to the IP or segment routing specifications.
> 
>    This document makes no changes to the segment routing architecture
>    and builds on existing protocol mechanisms such as the encapsulation
>    of MPLS within UDP defined in RFC 7510.
> 
>    No new procedures are introduced, but existing mechanisms are
>    combined to achieve the desired result.
