project overview
Project overview
  • Collaboration between RENCI and Duke University
    • ORCA framework (Duke NICL; Jeff Chase)
    • BEN – Breakable Experimental Network
      • 4-node dark fiber metro testbed managed by RENCI
      • Fiber switches
      • DWDM Transport equipment
      • Routers, edge resources
    • Infinera – industry partner
      • DTN platforms deployed in BEN in support of research activities
  • ORCA – flexible leasing core and supporting tools
    • Mature multi-year effort
    • Prototype capable of edge-resource provisioning
  • Goal – extend ORCA to support BEN resources
    • Demonstrate end-to-end slicing of an all optical network from PHY layer up

NDL
  • Origin: Universiteit van Amsterdam
    • SNE group
  • Under development for several years
  • In use within GLIF
  • Based on OWL/RDF
    • Can be used with RDF frameworks
    • Inference engines/reasoners
    • Query tools (SPARQL)
    • Other semantic web advances
  • Based on G.805 and the concept of adaptation
more on ndl
More on NDL
  • NDL strengths
    • Expresses adaptations/encapsulations
    • Expresses topologies
    • Can be used to express both existing configurations and requests
    • Understands the concept of wavelengths
    • Based on a rich set of semantic web technologies
  • Missing pieces
    • Wavebands
    • Spectrum extents
    • Edge and core node resources
orca ndl
ORCA+NDL
  • ORCA associates property lists with resources
    • Interpreted by controller plugins, not the core
  • At its simplest a property list is an XML document
    • Can be an NDL document
  • BEN controller would utilize an RDF framework to parse and operate on the descriptions
  • Requests also take the form of NDL
    • Can be merged with the specification in a single ontology
current progress
Current progress
  • Working on NDL description of BEN
  • Determining various possible configurations for demos
  • Near-term goal
    • Canned demos expressed as NDL, processed by ORCA
  • Longer term goals
    • Add ability to express spectrum regions
    • Edge and core node resources
    • Multi-domain
