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.

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

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.
