  1. End-to-end slicing in all-optical networks I.Baldine

  2. 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

  3. Cluster D • Kansei • Anish Arora, Ohio State • Hongwei Zhang, Wayne State • Vehicular Mobile Network • Brian Levine, Mark Corner, Brian Lynn, UMass • ViSE – Virtualized Sensing Environment • Jim Kurose, Michael Zink, Prashant Shenoy, David Irwin, UMass

  4. Slicing of a network

  5. Link slivering Cluster D

  6. BEN Equipment • Polatis fiber switches • ‘Grey’ • Establish a fiber path between nodes • Infinera DTN • DWDM Transport • Provisions circuits at a multiple of ODU-1 (2.5Gbps) granularity • Bandwidth Virtualization TM • Cisco and Juniper routers • VRFs and other virtualization features

  7. BEN Topology

  8. BEN Slice Options

  9. Slice Description

  10. 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

  11. 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

  12. 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

  13. 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
