1 OpenFlow/SDN activities of NTT Communications Yukio ITO NTT Communications Senior Vice President Member of the ONF Board 6 th June 2013

2 Virtualization Technology Server Physical Logical Storage Virtualize Network!? 1

3 Advantage of Virtualized Network Before DataCenter Srvc Control plane Data plane Various equipment BlackBox Different implementation Different interface Different user experience Complicated configuration Manual configuration to many equipments Human error Time consuming 2

4 Framework of SDN Software Defined Networking) New concept to realize software base NW functions lication layer: Policy, Security, Traffic engineering Control Plane Software Control plane: Topology, Routing Switch NW Equip. Switch Switch vswitch Data plane: Packet forwarding vswitch 3

5 What is OpenFlow? One of highly potential protocol to realize SDN Separate function in current equipment Current Equipment NMS/Provisioning CLI SNMP etc. OpenFlow Equipment API etc. Srvc OpenFlow Controller Control Plane Srvc Standard Protocol Srvc Control Plane OF-Agent OpenFlow Protocol OF-Agent Function Srvc Control Plane OF-Agent 4

6 OpenFlow s Advantages API etc. Realize network control from high layer system(program etc.) Reduce OPEX by automation OpenFlow Controller OF-Agent OpenFlow SW OpenFlow Controller OpenFlow Protocol OF-Agent OpenFlow SW Differentiation by installing original application onto controller Program rule of packets forwarding Shorten time to deliver new function to market OF-Agent OpenFlow SW Utilize commoditized cheaper SW Reduce CAPEX 5

7 Virtualized Network Complicated configuration of network equipment will be automated realizing on-demand delivery. DataCenter After Customer Portal Virtualized Service DataCenter Service Order and network configuretion automation On-demand configuration using virtual NW CTL 6

8 Findings after introducing OpenFlow/SDN Advantages: Integrated provisioning for Cloud and Network Service Order automation Bandwidth change Network configuration On-demand selection of appliance Easy and Topology-free design Issues: Specification need to be improved (OpenFlow v1.0) Shortage of operation and maintenance functions Limited capability for controller s redundancy etc. Switch Chip limitation Shortage of capacity to hadnle enough number of flows* *Common issues for OpenFlow Switch Hardware 7

9 NTT Com s SDN Archtecture Virtualize all Network API NW lication NW APP (intra-dc) NW APP (inter-dc) NW APP NW APP (Open Source) (Third Party) API Common framework SDN common framework Driver (plug-in) OpneFlow Controller CLI API Abstraction EMS etc. Forwarding OpenFlow Switch liance etc. Optical etc. 8

10 Use Case -Automation of GW interconnection- 1/2 Issues Automated in Cloud / Manual in interconnection with VPN Configuration changes in data center NW require complicated manual configuration works on VPN router Data center Network VLAN Configuration MPLS-VPN GateSW Router VLAN MPLS 9

11 Use Case -Automation of GW interconnection- 2/2 Solution by OpenFlow/SDN Automatic VPN connection via API from portal site API SDN Controller Data center Network OpenFlow GateSW ebgp Router MPLS-VPN VLAN MPLS 10

12 ToBe Model Image Cloud DC NW (Intra/Inter-DC) Virtualized Resource Cloud/Virtualized DC OpenFlow SW API Service NW Flexible & Quick Vendor-Free E-E Control DC-GW Automation Simplified Edge Virtual CPE by NFV Core Backbone NW Large Capacity (100G) Integrate wave control & transmission Packet transmission and Router-Less DC GW Edge PTN/ OXC Edge PTN/ OXC DC GW Edge Service NW PTN/ OXC Edge PTN/ OXC PTN/ OXC DC GW Edge CPE(NFV) Next Gen PTN/Optical Protocol conversion SDN Common Platform SDN Controller Orchestrate endend resources over multi-layers 11

13 Open Networking Foundation (ONF) Established in the spring of 2011 NPO heading an network evolution by development of SDN s architecture and standardization Propagation and commercialization of SDN s basic technology Promoting standardization of OpenFlow as open technology Leadership by service provider, as telecom carrier and cloud service provider etc. Many network equipment vendors participation ONF Board of Directors Google,Facebook,Yahoo,Verizon,Deutsche Telekom,NTT Communications, Microsoft,Stanford,UC Berkeley,Goldman Sachs Urs Hölzle (google ) Chairman Nick McKeown (Stanford) Yukio Ito (NTT communications) Dan Pitt Executive Director 12

14 Contribution to Propagate OpenFlow/SDN bizcloud [Article] The State of OpenFlow and SDN at One of the World s Largest Infrastructure Providers NTT (May 8, 2013) Converge Digest [Report] NTT Communications was among the first Service Providers to see the potential of OpenFlow and SDN for transforming its operations (Apr 21, 2013) OpenFlow/SDN SDNCentral [Exclusive Interview] NTT Communications on SDN Benefits (May 7, 2013) SDN ZONE [Article] NTT Communications Outlines Success of its Enterprise Cloud Platform (Apr. 19, 2013) 13

15 Conclusion What NTT Com has done / are doing / will do? Done : Provided Enterprise Cloud with OpenFlow/SDN Doing : Testing cloud interconnection with VPN Will do : Expand to all layers of network Aggressively working on OpenFlow/SDN controller development to realize unique service and quick delivery Contribute to lead ONF for propagation and commercialization of SDN technology CHANGE THE WORLD!! 14
