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

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

BEN Slice Options

Slice Description

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 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 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 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
