ARCH, Architecture Compliance

Description:
A solution to compress SR for the IPv6 dataplane MUST be compatible with the specifications describing the instantiation of SR for the IPv6 dataplane including:
- RFC8402
- RFC8754
- draft-ietf-spring-srv6-network-programming
- draft-ietf-spring-segment-routing-policy

Along with the other working group control plane and OAM specifications
draft-ietf-lsr-isis-srv6-extensions
draft-ietf-bess-srv6-services
draft-ietf-idr-bgpls-srv6-ext
draft-ietf-spring-sr-service-programming
draft-ietf-6man-spring-srv6-oam

Rationale:
Building upon multiple years of work by SPRING to define SRv6 (the instantiation of SR on the IPv6 data plane) builds on the collaboration, review, implementations, and deployments associated with this work.
It is desirable for SPRING to reuse the SRv6 specifications for any compressed SRv6 solution.

Metric:
 The compliance metric (C) records how aligned a proposal is with the
   SRv6 solution.

   o  C.RFC8402: compliance with [RFC8402]
   o  C.SRH: compliance with [RFC8754]
   o  C.PGM: compliance with [I-D.ietf-spring-srv6-network-programming]
   o  C.IGP: compliance with [I-D.ietf-lsr-isis-srv6-extensions]
   o  C.BGP: compliance with [I-D.ietf-bess-srv6-services]
   o  C.POL: compliance with [I-D.ietf-spring-segment-routing-policy]
   o  C.BLS: compliance with [I-D.ietf-idr-bgpls-srv6-ext]
   o  C.SVC: compliance with [I-D.ietf-spring-sr-service-programming]
   o  C.OAM: compliance with [I-D.ietf-6man-spring-srv6-oam]

   Each of the above metrics are assigned a compliance value:
   o  10: complies with the specification
   o  5: extends the specification
   o  0: redefines the specification

   C.TOT is the sum of all C.* metrics listed above.  It provides an
   overall assessment of the proposal's alignment with the SRv6 RFCs and
   working group drafts.
