2. 2 Evolution of SDN services in NTT Communications
3. 3 Step1: Enterprise Cloud Services First private cloud in the world adopting virtualized network technologies launched in June 2012 ü  Automatic configuration using SDN technologies ü  On-demand provisioning through customer portal ü  Direct connection to VPN SDN  tech.  deployed  to   inside  of  DC Germany  (Mar.  2014)   UK  (Feb.  2013)   Australia (May.  2013)   India (2015)   China     [Hong  Kong]   (Jun.  2012)   Spain (Mar.  2015)   France (Mar.  2015)   US     [2  locaJons]   (Feb.  2013)   China    [Shanghai]   (2015)    Japan     [2  locaJons]   (Jun.  2012)   Singapore  (Feb.  2013)   Malaysia  (Mar.  2013)   Thailand  (Mar.  2013)   ＋[1  locaJon]    　 　    (Dec.  2014)  
4. 4 Step2: Between Enterprise Clouds Dynamic virtualized network between DCs ü  Customers can control network resources ü  Typical Use Case: On demand global data backup OFSW* OFSW* Country A Virtualized Network between Data Centers Enterprise Cloud Enterprise Cloud Customer Portal * OFSW : OpenFlow Switch Data center in Data center in Country B Network Controller SDN  tech.  deployed  to   b/w  DCs
5. VLAN-MPLS gateway eBGP Open Flow VLAN MPLS API SDN Controller ü  Configurations of DC and VPN are exchanged and mapped each other at the gateway automatically (VLAN<->MPLS) ü  Delivery time: Several days -> hours 5 Data centre Network MPLS-VPN Step3: Cloud-VPN inter-conn automation 　 Flow  tables SDN  tech.  deployed  to   b/w  DC  and  WAN
6. ADP ADP SW ü  Realize flexible connections without changing the current physical network In-house Locations Overlay Function Newly-launched Overseas Locations Internet Company A’s System : Connection Route : Software Virtualize Network Customer Portal Network Controller ADP SW : Adaptor 6 (Company B) Locations acquired by M&A Arcstar Universal One Other VPN Step4: Virtualized Overlay Network SDN  tech.  deployed  to   overlay  NW  on  WAN
7. 7 Network Internet : Connection route Customer Portal Realize functions of WA and FW over network Network Controller Customer’s system Step5: Network Functions Virtualization ü  Virtualize network appliances on LAN with software over Arcstar Universal One. After NFV service SDN  tech.  deployed  to   NFV
8. 8 Step6: Transport SDN Cloud Connectivity  Domain  -‐‑‒  Physical Core  Domain  -‐‑‒  OTN Aggregation  Domain  -‐‑‒  MPLS DC  Domain  -‐‑‒  VLAN •  SDN technology deployment to carrier core networks. •  Aims to realization of “Carrier cloud”: high quality integrated cloud/network services under •  Multi-Domain (Access, Aggregation, Core,…) •  Multi-Layer (Fiber, WDM, OTN, MPLS,…) •  Multi-Vendor ɹ network environment Integrated  control  of  multi-‐‑‒domain/layer/ vendor  transport  networks SDN  tech.  deployed  to   core  NW  of  WAN

10. 10 Our Activities on Transport SDN
11. 11 Use Case1: Integrated Network Visualization •  Multi-layer/Multi-domain/Multi-vender NWs are managed integrated through one-view. •  Operators can easily grasp whole network situations by virtualization and abstraction of network resources. Ether  domain Operator MPLS  domain Operator WDM  domain Operator Per  layer/domain/vendor  view Integrated  “one-‐‑‒view” Traditional  Operation ToBe  Operation
12. 12 Use Case 2: Multi-layer/domain Optimal Path Allocation Use Case 3: Multi-domain Auto Recovery •  Optimal end-to-end path allocation among multi-layer/domain networks. •  Discover candidate paths automatically •  Select a path based on operator’s policy •  Auto recovery of all end-to-end paths beyond domains Traditional  Operation ToBe  Operation Per  layer/domain/vendor   Operation Overall  Optimization  Operation Optimal  paths   per  domain End-‐‑‒to-‐‑‒end   optimal  path   allocation Failures   between   domains  must   be  recovered   manually Auto  recovery   beyond   domains  on   end-‐‑‒to-‐‑‒end   basis
