Typical Flow Handling In Broadcom Switch
1. Simultaneous processing of multiple flows, e.g., L2, L3 (v4, v6), MPLS, VxLAN etc.
2. Tenant-level classification, ACLs and metering
3. Load Distribution across wide overlay and underlay ECMP Paths
4. In-line instrumentation and telemetry across packet processing pipeline

What is DCI?
 Data Center Interconnect (DCI) is the process of connecting two or
more locations typically with Layer-2 or VLAN connectivity
 Can be accomplished with dark fiber direct links, VPN, or tunnel
encapsulation methods

DCI Use Cases
 Active-Standby DCI
‒ To enable a Disaster Recovery (DR)
strategy to provide resilience to data
center applications in the event of
disaster events
‒ Geographical Dispersed DCs
‒ Incremental Data Center Migration
 Active-Active DCI
‒ Elastically share workload resources
across sites
‒ Seamless Workload Mobility
