Multi-layer Control Plane

  1. 1. Multi-Layer Control Plane<br /> Session: Packet-Optical Transport & Switching Innovation<br />Joe Whitehouse<br />Metaswitch Networks<br />Network Technologies Division<br />Joe.whitehouse@metaswitch.com<br />
  2. 2. Metaswitch Control Plane Expertise<br />Previously Data Connection Ltd. (DCL)<br /><ul><li> Network Protocol source code since 1983
  3. 3. 1st portable GMPLS protocol solution
  4. 4. 1st portable O-UNI protocol solution
  5. 5. 1st portable LMP protocol solution
  6. 6. 1st portable G.709 OTN protocol solution

  8. 8. P-OTS: Don’t Forget About the Control Plane<br />Control plane functions<br />Automated LSP set up, tear down<br />On-Demand provisioning<br />Automated protection & restoration<br />Link bundling<br />Automated discovery<br />Control plane benefits<br />Reduced OPEX<br />Facilitates network migration<br />OAM negotiation<br />Increased availability<br />Quicker service set up time<br />Reduced human errors<br />New services<br />Key application for service providers:<br /> ASON/GMPLS Control Plane<br />Source: Infonetics, 2011<br />
  9. 9. Multi-Layer Control Plane<br />Multiple layers can include<br />MPLS-TP transport service sublayer<br />MPLS-TP transport sublayer<br />TDM layer (ODU)<br />WDM layer (OCh)<br />GMPLS is common<br />Carriers use only the layers needed<br />
  10. 10. Multi-Layer Control Plane: Making it Work<br />Client – Server model<br />Common in our industry: see IETF, MEF, OIF UNI implementations<br />Horizontal and vertical interoperability<br />Source: OIF<br />
  11. 11. Inter-Area Control Plane ConsiderationsPCE<br />Optimal path<br />calculated<br />Optimal path<br />calculated<br />Optimal path<br />calculated<br />DomainB<br />Domain C<br />Domain A<br />= PCE Server<br />= PCE Protocol<br />= TE Path<br />More than just inter-area solution<br />Lower CAPEX<br />Optimal relocation of network intelligence<br />Solves complex routing issues (WDM/OTN)<br />
  12. 12. Summary<br />Control plane has significant benefits<br />Large demand by service providers<br />P-OTS/OTN = Multi-layer Multi-layer control plane<br />GMPLS is common across layers<br />GMPLS standardized and well understood for years<br />Inter-area and client-server considerations to be made<br />
