OTN Control Plane, PCE, & Software Defined Networking

  1. 1. OTN Control Plane, PCE, &Software Defined Networking Joe Whitehouse
  2. 2. Control Plane Demand OTN Deployments = Control Plane Deployments
  3. 3. 2012 OIF Interoperability (ASON/GMPLS Control Plane) Accomplishments GMPLS for OTN E-NNI 2.0 / UNI 2.0 Multi-layer Multi-vendor Multi-carrier Full details: http://www.oiforum.com/public/OIF_at_OFC2012.html
  4. 4. A More Detailed (Realistic) View Domain could mean vendor, carrier, network, and/or layer homogeneityCP requests likely to be E-NNI shows abstracted topologiesNMS driven, not UNI for interdomain networking OSS/NMS Domain A Domain B Domain C Client Client UNI E-NNI E-NNI I-NNI I-NNI I-NNI I-NNI CP can not see outside its domain UNI User Network Interface I-NNI Internal Network-Network Interface E-NNI External Network-Network Interface CP Control Plane
  5. 5. Interdomain Networking & PCE Sometimes an “abstracted topology” is not enough Abstractions may not provide optimal e2e path Topology sharing concerns Enter: Path Computation Element (PCE) Provides optimal and secure interdomain networking Fully customizable Improved price/performance ratio Simplified operations Ideal for complex routing decisions (i.e. WDM) IETF standard PCE also provides a path to the cloud & SDN!
  6. 6. PCE: An Evolutionary Approach to SDN [for Telcos] PCE separates control and data planes In a way telcos can tolerate PCE opens control of the network Enables customization of path set up PCE simplifies operations Modifications/upgrades to a centralized COTS server Not a network element PCE improves pri ce/performance ratio Add processing power to a COTS server Add PCEs, hierarchical PCEs as needed All the same attributes which are driving SDN momentum.
