What Is anEthernetFabric?

Optimized for server virtualizationand cloud architectures More efficient, higher throughput,

lower latency Scale-out vs. scale-up to increase

flexibility and reduce cost Dramatic automation to simplify

administration

• Inflexible: Deployed as three tiers, optimized for legacyclient/server applications

• Inefficient: Spanning Tree disables links to preventloops, limiting network utilization

• Complex: Additional protocol layers to enable scale• Expensive: Each switch has to be managed individually

• Flexible: Topology optimized for east/west traffic patternsand virtualized applications

• Scalable: Flat topology easily scales out at the edge• Efficient: All links in the fabric are active with Layer 1/2/3

multipathing• Simple: Entire fabric behaves as logical switch

Orchestration

• Innovation is limited by the capability of the networking vendors

• Old approach is decades behind compared to Web 2.0 and SP Cloudprovider requirements:• Scale

• Operational Efficiency

• Service Velocity

OpenFlow Hybrid Mode

• Industry’s first true OpenFlow Hybrid mode• Enables co-existence with today’s networks• Enables new services to be added

• Coexists with traditional IP/MPLS networks• OpenFlow overlay runs concurrently with

traditional IP/MPLS routing/switching• Flexible flow identification

• Optional “protection layer” isolatesOpenFlow rules from those populated bycommon control protocols

Preserves past investment while laying foundation for the future
