p4srv6 ... proto-typing SRv6 functions with P4 lang.

The objective of this project is to implement SRv6 functions still under discussion using P4 Lang to make running code available for testing and demo. Since there is no Open Source P4 switch implementation supporting SRv6, this should include basic switch features required to test SRv6.

List of SRv6 functions of interest and status:

• draft-filsfils-spring-srv6-network-programming-04 * T.Insert * T.Encaps, T.Encaps.Red * End, End.DT6
• draft-ietf-dmm-srv6-mobile-uplane-01 * End.MAP (future) * End.M.GTP6.D * End.M.GTP6.E * End.M.GTP4.E (future) * T.M.Tmap (future) * End.Limit (not planned)

List of helper actions:

• GTP * Encap/Decap GTP-U

slicing-srv6's Issues

All issues

SRv6/GTP related refactoring

• UDP Checksum Support (gtpu_encap_v6, End_M_GTP6_E)

• End support without specifying SL.

• Add L3 routing (basic)
  * IPv6/IPv4 LPM lookup
  * rewrite dstMacAddr
  * no ECMP (indirect next hop)

• Add L2 "static" switching
  * lookup dstMacAddr and set standard_metadata.egress_spec
  * flood if miss

• Add L2 switching (mac learning bridge)
  * lookup srcMacAddr
  * send packet to CPU if miss
