  2. Cloud Data Center MarketTwo Macro Trends 1. Top Investment Drviers: Virtualization & Security 2. Consolidation & Cloud Trends = Rise of Large Scale Data Centers Source: Data Center Deployment and SDN Strategies: North American Enterprise Survey - October 25, 2012

  3. 10G / 40G Adoption Spirent new DX2 / FX2 line and 400G ready chassis provide best of breed solutions for high density 10/40/100G testing.

  4. Other DC Investment Drivers • Spirent is focused on solutions for the top two concerns • Virtualization • Large DC adoption of VM much faster: 53% increase projected in the next 12 months alone! • Spirent’s Virtual Solutions validate performances of VM, Virtual Switches, NFV, Hypervisors… • AppSec • Security & App Performance are top concerns • Avalanche Virtual & Avalanche Next is industry leading AppSec testing solutions

  5. How about SDN?(Hype? or Not?) '12 - '18 Market Forecast by Product Category SDN Spend by Use Case Cloud Service Provider Datacenter - Hyper-scale Datacenter, Web 2.0 Datacenter Service Provider - WAN Edge, Metro, Core, Mobile Backhaul, Mobile Packet Core Source: Lightspeed ventures and SDNCentral

  6. Hype Aside – Cloud Data Centeradoption of SDN is real!

  7. Data Center Networks

  8. Large Scale Ethernet Fabric Tests • June.2012 - World Largest Ethernet Fabric Test – Juniper • 1,536x 10G Ports • 2.357M Low Latency L2/3 streams • Multicast w/ IGMP • In Progress – with two vendors • 384x 40G ports • 40x 100G ports • Spirent is Leader in This Space! • Test Throughput, Queueput, forwarding, frame loss, congestion • RFC 2889, Benchmarking Methodology for LAN Switching Devices • RFC 2544, Benchmarking Methodology for Network Interconnect Devices • RFC 3918, Methodology for IP Multicast Benchmarking • Draft Data Center Bridging Benchmarking (tests 802.1Qbb and 802.Qaz) • RFC 5180, IPv6 Benchmarking Methodology for Network Interconnect Devices • RFC 4814, Hash and Stuffing: Overlooked Factors in Network Device Benchmarking

  11. Spirent fX2 • Highest Density of any Test Module in its Class • Industry-leading 10G density – 20 ports per slot • Industry–leading 40G density – 5 ports per slot • Industry-leading dual-speed 40G/10G density (speed set per QSFP+ port) • Speed configurable per QSFP+ port • 64K Tx and 128K Rx streams per port first release & increasing thereafter!

  12. QSFP+ Overview • dX2 and fX2 modules come with QSFP+ interfaces • QSFP+ = quad SFP+ • Equivalent to 4 SFP+ interfaces in a smaller QSFP+ package • Can run 40G Ethernet as well as 4 x 10G Ethernet • 4 x 10G operation connected to a SFP+ DUT requires “breakout” cable options

  13. VXLAN • Unknown MAC address sent via multicast to all other VTEPs • VTEPs learn VM Mac to VTEP IP mappings similar to a Bridge • Known MAC address sent via point-to-point tunnel between VTEP • Mac-in-IP Overlay • VTEP (typically Vswitch) maps VMs to VxLAN tunnel • 24 bit VXLAN Header (16M VXLANs) • Crosses Layer 3 boundaries

  14. Typical Test Scenarios Wizard: • Create multiple VTEPs and VMs behind the VTEPs • Create VMs (hosts) behind the customers switch • Create traffic between the VMs • Enable IGMP on the VTEPs • Map VMs to a multicast group • Map VMs to a VXLAN segment Tests: • VTEP Performance / Scale • Mac / VXLAN Scale • Mac Learning / Multicast • VM Mobility • Duplicate Mac / VLAN • Traffic Leaking between VXLAN Testing Virtual VTEP Testing Physical VTEP Large Scale VTEP & VM Emulation

  33. Improving Software Engineering Efficiency Using Dynamic Virtual Test Bed

  34. A new direction … Continuous Integration • SW Development Process • Integrate Code Daily • Each Integration Verified/Tested • Detect integration errors quicker • Reduced integration problems • Cohesive Software Development

  35. What does Spirent’s CI look like …

  36. NEM Based Continuous Integration Case Study *Metrics are based on manual and approximated calculations due to lack of rigorous monitoring ** Indicates a successful build or test cycle and omits failures

  37. Solution Today: STCvAVv & iTest

  38. Success Story: Why a major NEM chose iTest and STC? • Challenges • Regression testing takes 4 days • Must manually configure DUTs • Testing Edge Router requires 3 additional DUTs and 84 test ports • Results • iTest reduced time to test to 7 hours • STC supports “device-behind-device” reducing required ports to 24 • Reduce test-bed cost to $200k from $1M
