  1. Alibaba: World’s Leading Cloud Data Center SDN Commercial Network

  2. There’s a Navigator in Each Stage of the Internet Era… 1995, Jeff Bezos founded Amazon One of the earliest e-Commerce Company Start Internet B2Cmodel 1994, Jerry Yang and David Filo founded Yahoo! A twentieth century Internet miracle Start Internet portal website model 1999, Ma Yun founded Alibaba The world's largest e-Commerce platform Start Internet B2B model 1995, Omidyar Pierre founded eBay One of the earliest online auction companies Start Internet C2C model

  3. About Alibaba • World’s second largest Internet company, valued at $190B USD • World's largest online and mobile transaction platform, with yearly transaction volume exceeded $240B USD in 2014 • China's largest IaaS cloud computing provider, with 1.4M+ cloud tenants • $14.5BUSD was transacted from sales on November 11, 2015 (6x more than the US's Black Friday) AlibabaBusiness • E-commerce, Cloud Computing, Online-payment, Logistics, Vehicle-ordering, Search, Video, etc.

  4. Alibaba : E-commerce Giant and Leading Cloud Service Provider • November 11 • Global Shopping Festival Self-run services provided Search service provided • Taobao goes live $14.5B/Day • Aliyun company • established Private Cloud 2010 2013 2003 2015 1999 2004 2011 Public Cloud • Alipay goes live • Alibaba IaaS cloud service • goes live 2009 • Alibabaestablished 1.4M+tenants

Leap-Frog Service Development Drives Data Center Network Architecture Revolution Service type • Traditional service • 3K GEservers/DC • Private cloud service • 10KGEservers/DC • Public & private cloud service • 20K10GEservers/DC IT requirements V3.0 V4.0v V3.5 40GE/100GE SDN Controller … 40GE 10GE DC network architecture 10GE 40GE POD1 … PODN POD1 … PODN • Large-scale fabric • Layer 3 fabricnetworking • Super large SDN • Hardware VXLANSDNsolution • Medium-range fabric • Layer 3 fabricnetworking

  6. Business Globalization Drives Scaled Construction of Cloud Data Centers 20+Cloud Data Centers 400K+ Servers … Beijing Hangzhou Qingdao Shenzhen HongKong Shanghai Germany Japan Dubai Silicon Valley Singapore

  7. Carrying massive cloud services brings about huge challenges to Alibaba 4.0v Private cloud service Public cloudservice Super large server cluster Huge data exchange Operable large IaaSpublic cloud Hour-level Service provisioning Tenant level measurement 1.4M+ multi-tenant support 20K+ 10GE Servers/DC 800+ Switches/DC Challenges to Alibaba 4.0v Service Oriented Network Automation High-Performance High-density Access highly efficient flexible Multi-tenant Network

  8. Huawei Helps to Build Alibaba's 4.0v SDN Network for Super Large Cloud Data Centers Ali • Decoupling • between service and physical networks • Separation between Overlay and Underlaynetworks • Flexible service deployment not limited by physical networks • Advanced • Architecture • Alibaba • Controller SDN Agile Controller • Hardware VXLANsolution: builds a highly efficient & flexible Overlaynetwork • Open SDNsolution: Agile Controller implements automation on the Overlay network and provides tenant-oriented refined O&M Overlay service network VXLAN ZTP • The core switching platform provides three times the industry's average performance to ensure high-performance forwarding on the Underlay network • Zero Touch Provisioning (ZTP): implements automatic O&M of the Underlay network CE12800 Underlay physical network

  9. Hardware VXLAN Solution Helps to Build a Highly Efficient Flexible Overlay Network … • Hardware VXLAN Solution Tenant 1 Tenant 2 Tenant N Agile Controller • Provides a dedicated network for a large number of tenants (16M tenants maximum), with security isolation for tenants • Easy to build large-scale virtual networks (compared with the software VXLAN solution) CE12800 VXLANGW VXLAN • N • hardware nodes CE7800/6800 /5800 OVS • 40*N • vSwitchnodes OVS … $ Millions • 2times • 40times Server cost saving • Server's forwarding performance • Number of management nodes

  10. SDN Implements Overlay Network Automation to Shortens Service Provisioning Period Ali • Shortens the service provisioning period • from one week to one hour Ali controller • Tenant network automation • The Agile Controller works with Aliyun to implement network automation for tenant services • Virtual and physical networks are uniformly planned for service transmission Restful Agile Controller Openflow/Netconf • Fast processing of ARP service • Controller process the ARP packets to reduce the load on GWs • The controller sends ARP packets to multiple GWs using OpenFlow to ensure ARP entry consistency VM/存储 物理网络 虚拟网络

  11. Innovative Network Measurement Capability Realizes Refined O&M for Tenant Networks • Measurement and visibility • Visible network-wide resources, traffic, and tenants • Visible forwarding paths between VMs, realizing unified O&M of physical and virtual networks Agile Controller Quick fault diagnosis • The Agile Controllercan work with CloudEngine switches to quickly detect faulty linksto solve single-point abnormalities • Proactive O&M • Traffic adjustment • Capacity planning • Configuration change VM1 VM2

  12. ZTP Realizes O&M Automation for the UnderlayNetwork Power on and check • Power on TORs and check whether they are not pre-configured • Start the ZTP process Zero-Touch Provisioning 1 20,000+servers 800+network devices Manually in one day Download scripts • Obtain the device's IP address, gateway, DNS, script name, and file server address from the DHCP server • Download scripts to the local device ZTP 2 Load and start scripts • Automatically generate the configuration file name based on the TOR's ESN • Download the software version and configuration file • Set the startup file to restart the TOR Automatically in one hour 3 • Batch deployment • Connect multiple TORs in a batch. • Plug-and-play • A device works instantly once powered on. • Openness & customization • Customizable Pythonscripts

  13. Nonstop Switching Platform Improves 350 Million Users' Online Shopping Experience • Nonstop switching platform • with 20K+10GE server cluster • Core switches performing at • 3x industry's average performance • First-rate shopping experience • for 350M+ users GMV: $14.5B USD Online orders: 710M Transaction Qty.: 140,000/s Payment Qty.: 85,900/s 40GEinterconnection 100GEbackbone 20,000+servers 800+ network devices 160 Tbpsswitching capacity 36*100 GEhigh-density card 2~5 uslow latency 18 GBlarge buffer
