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

Cluster D
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

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
