2 Access Aggregation Core Edge Core Ethernet Fabrics vs. Legacy Networks AUTOMATION, EFFICIENCY AND SCALE ON-DEMAND CLASSIC, HIERARCHICAL ARCHITECTURE ETHERNET FABRIC ARCHITECTURE Scalability Inflexible: Rigid architecture, optimized for legacy client/server applications Inefficient: Spanning Tree disables links to prevent loops, limiting network utilization Complex: Each switch managed individually VM-ignorant: No concept of server virtualization Flexible: Topology freedom, optimized for east/west traffic patterns and virtualized applications Efficient: All links in the fabric are active with Layer 1/2/3 multipathing Simple: Entire fabric behaves as logical switch VM-aware: Facilitates VM/network interoperability 2/28/ Brocade Communications Systems, Inc. Proprietary Information
3 TRILL Encapsulation Ethernet frame in Fabric 2. RB1 adds TRILL header and outer MAC header MAC-RB4 MAC-RB1 RB3 RB1 MAC-T MAC-H Data RB1 Known unicast destinations are forwarded RBridge hop by RBridge hop toward the egress RBridge No Learning RB4 RB5 MAC-RB3 MAC-RB4 RB3 RB1 MAC-T MAC-H Data RB3 3. RB3 removes TRILL header and associates MAC-H with RB1 1. Host sends frames MAC-T MAC-H Data H RB2 Normal Learning T Learn H -> RB1 MAC-T MAC-H Data 4. Target receives frames
