The ogrammable ptical work*:
Enabling the Design, Development, Deployment & Demonstration
of Innovative High-Speed Low-Latency Net-Centric Applications & Experiences
* This research is made possible by a grant from The NaHonal Science FoundaHon under the provisions of NSF 15.534, “Campus Cyberinfrastructure, Data, Networking and Innova;on Program” -‐ (CC*DNI) Program SolicitaHon
“Without high-‐performance networking, big data and high performance compu;ng have very limited value. It has long been recognized that the highest performance data transfers should directly run on top of op;cal circuits without Ethernet switching or IP rou;ng. This direct layering avoids switching-‐related packet loss and provides a cost-‐effec;ve service. Op;cal equipment now exists that will permit the dynamic establishment of single applica;on light-‐paths. However, the ;me required to set up op;cal circuits is too long for short or small transfers – taking a second to set up a 100 Gigabit/sec link in order to transfer a small file does not make sense. This project is building an integrated campus network where small data transfers (megabytes or gigabytes) ride conven;onal networks and big data transfers (terabytes or petabytes) ride directly on op;cal circuits.
The project is building PROnet, a campus network at the University of Texas -‐ Dallas, which provides the lowest possible network latency -‐ signal propaga;on only -‐ scalability to 100Gbps and beyond, and equipment having low power consump;on and complexity. A user-‐friendly interface will be developed and deployed for the network inexperienced researcher to request the provisioning of as needed op;cal. A PROnet controller will be developed for the scheduling and automa;c provisioning of op;cal circuits, which will shorten the circuit reserva;on procedure ;me significantly by removing human interven;on from the en;re process. For inter-‐domain opera;on, the open plaYorm OSCARS will be extended to work with PROnet. With this OSCARS extension, provisioning of hybrid (op;cal and virtual) circuits spanning across mul;ple (op;cal and non-‐op;cal) domains will be a reality. The so[ware will support secure use of the network via InCommon iden;;es.” Source: NSF proposal narrative
-Enabled Services
• IniHally will be a prototype consisHng of off-‐the-‐shelf products as well as prototype modules developed at UT Dallas and enabled to funcHon as a circuit-‐oriented network soluHon
• Users/clients will be made aware of the prototype nature of . They will understand that accept that outages and/or malfuncHons can occur from Hme to Hme as development work proceeds
• Over Hme, will transiHon into a stable network product offering: 1. ProducHon circuits (mostly staHc with built-‐in reliability) on a 24/7 basis to
UT Dallas and other parHcipaHng organizaHons throughout Texas 2. PorHons (slices) of the resources to parHcipaHng researchers and
scienHsts to test innovaHve network services and opHmizaHon procedures 3. Circuits “on-‐demand” to users/clients, including:
a. Researchers working at -‐connected campuses, requesHng circuits for a specified period of Hme
b. IT Offices of user organizaHons requesHng dedicated circuits for semi-‐producHon purposes
c. Users of enterprise IP management so\ware seeking dynamic and automaHc creaHon of circuits
• The enabling module for all of these services is the Orchestrator, which will be capable of parHHoning (slicing) and managing the available network resources.
– Campus-to-Campus Example
Intra-Campus
Device-‐to-‐device connec,vity: • Range of transmission capaciHes = 1, 10, 20, …, 100 Gbps • For intra-‐metro applicaHons, end-‐to-‐end round trip Hme in the 1 ms range
• The technology can be extended to offer inter-‐metro connecHvity. Round trip Hme increases proporHonally with geographical distance
60 km

Aligns with the US Ignite Initiative
• US Ignite, a 501(c)3 nonprofit organizaHon recently launched by the White House Office of Science and Technology Policy (OSTP) and the NaHonal Science FoundaHon (NSF), seeks to foster the design and development of shareable innovaHve applicaHons and digital experiences enabled by high-‐speed low-‐latency networks. These applicaHons will have the potenHal to transform how we access and experience everything from weather reports, personalized healthcare, library resources and transportaHon services while at home, at work, or while mobile.
• US Ignite helps maintain US global leadership in innovaHon by leveraging the collaboraHve capabiliHes of industry, government, and academia.
• To bring these applicaHons to life, developers leverage the unique capabiliHes of next-‐generaHon networks, including
• 100 Mbps+ and low latency, permidng, for example, mulHple bi-‐direcHonal streams of uncompressed video.
• So\ware-‐defined networks (e.g., OpenFlow), promising dramaHcally-‐improved control over network rouHng and opHmizaHon.
• Networks with capabiliHes such as virtual network “slices” matched to applicaHon requirements and distributed programmable resources throughout the network.
• Integrated wireless networks to facilitate, for example, sensor networks and conHnuous remote monitoring.
• ApplicaHons built to be open, shared, and extendable.
