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
