  2. Introduction • draft-li-ospf-ext-green-te-00 has been proposed in IETF 86. • The architecture of Central Controlled IGP has been proposed in [I-D.li-rtgwg-cc-igp-arch-00]. • Energy Saving can be a useful usecase for Central Controlled IGP.

  3. MPLS TE vs. MPLS Green TE • MPLS TE is used to optimize the efficiency of network. • More constraints are included: Bandwidth, Color, TE Metric, SRLG…… • CSPF will calculate the path at first. Then RSVP-TE will make the tunnel. • Does CSPF also consider the energy consumption of each link in the network?  MPLS Green TE • 100M/100W • 100M/100W • ? • 100M/50W • 100M/50W • 50M/50W • 50M/50W

  4. Centralized MPLS Green TE • IGP-based Central Controlled framework can be used for MPLS Green TE: • IGP controller collects energy consumption info through IGP extensions. • Reasonable energy-saving path computation based on complete topology information and state information of the whole network. • Ordered Traffic Switch to energy-saving path by Central Controller.

  5. OSPF Extensions • OSPF TE link LSA should be extended. • The new TLV will be named as "Energy consumption of Link TLV“. It is used to represent the energy will be consumed by the link. • Its unit is Watts. • 0 1 2 3 • 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 • +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ • | Type(TBD) | Length = 4 | • +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ • | Energy consumption of link | • +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ • The information will be flooded through the OSPF area with TE Link LSA.

  6. Next Steps • Algorithm research on energy-saving path computation and traffic switch. • Solicit comments and feedback on the draft. • Revise the draft.
