  1. CORD    Delivering  cost-­‐performance  leadership  and  cloud-­‐style  agility  to  Service

     Provider  networks     Central  Office  Re-­‐architected  as  Datacenter  (CORD)  briefing   An  ONOS  Project  solu1on  POC  
  2. 1 CORD  Partnership   2 What  is  CORD?   CORD

     is  an  end-­‐to-­‐end  solu1on  POC  that  combines  SDN,  NFV,  Cloud  with     commodity  infrastructure  and  open  building  blocks  to  deliver  datacenter     economies  of  scale  and  cloud-­‐style  agility  to  service  provider  networks   3 CORD  Value  proposiAon   4 CORD  open  building  blocks   ONOS(SDN  Control  Plane),  Openstack(Virtual  infrastructure  mgmt),  XOS  (Services   mgmt),  open  commodity  hardware,  OF-­‐enabled  OLT  MAC  and  G.fast  DPU   CORD  enables  service  providers  to  build  an  underlying  common  infrastructure   in  Central  Office  with  white  boxes,  ONOS,  OpenStack,  and  XOS  with  a  diversity   of  organiza1ons  building  the  services  and  solu1ons  above.                          CORD  Highlights  
  3. What problems does CORD address?

  4. Large number of COs Evolved over 40-50 years Huge source

    of CAPEX/OPEX Problem:     Today’s  Telco  Central  Offices  (COs)  are  huge  source  of  CAPEX/OPEX   •  Fragmented  non-­‐commodity  hardware.   •  Physical  install  per  appliance  per  site   •  Nearly  300+  unique  deployed  appliances.     BNG   Firewall   DPI   CDN   Message Router   Carrier   Grade  NAT   Session  Border Controller   PE  Router   SGSN/GGSN/ PDN-­‐GW   Source: AT&T and  their  design/infrastructure  is  not  geared  for  programmability,  agility   What’s  needed?  Common  underlying  infrastructure  based   on  commodity  hardware/whiteboxes  and  open  pla\orms  
  5. Problem:     Piecemeal  virtualiza1on  does  not  yield  full  benefits

     of  SDN/NFV/Cloud   Broadband   Network     Gateway   Eth  Agg     OLT   10  GigE   (LAG)   PON  Spli^er   CPE   CPE   ONT   ONT   Phone   Phone   STB  w  DVR   STB  w  DVR   PC   PC   Telco  Central  Office        Subscriber  home   2.5 Gb/s 1.25 Gb/s What’s  needed?  An  End-­‐to-­‐end  solu1on  that  spans  CPE,  diversity  of  access(GPON,     G.fast  etc)  and  Central  Office  to  get  maximum  benefits  of  SDN/NFV/Cloud   Source: AT&T 300+  appliances     (Firewall,  DPI,  CGNAT..)        Subscriber  home  
  6. Introducing CORD
