Overview
The Broadcom® BCM88770 is the fourth generation in the StrataDNX™ product line of Fabric Element (FE) devices and is a self-routing cell-based switching element. Together with the BCM88670 and BCM88680, the BCM88770 provides a complete solution for switching fabric, traffic management, packet processing, and network interfaces. Switching platforms can scale up to 6,000 100GbE ports.
The BCM88770 provides scalability in three dimensions: port rates, port count, and traffic management services, allowing the user to connect mixed-rate line cards, for example 100 Gbps through 3.6 Tbps each, with various traffic management schemes.
The BCM88770 is used to build a variety of network switch solutions:
• Over 100 Tbps core/edge switches with singlestage fabric for data center, packet transport, or carrier network applications.
• Multiple interconnected chassis of different capacities, using the BCM88770 two-stage fabric to create a scalable core platform that delivers up to 6,000 ports of 100GbE or their 40GbE/10GbE equivalents.
Features
