The Broadcom® BCM88770 is the fourth generationin the StrataDNX™ product line of Fabric Element(FE) devices and is a self-routing cell-basedswitching element. Together with the BCM88670 and BCM88680, the BCM88770provides a complete solution for switching fabric,traffic management, packet processing, and networkinterfaces. Switching platforms can scale upto 6,000 100GbE ports.
The BCM88770 provides scalability in threedimensions: port rates, port count, and trafficmanagement services, allowing the user to connectmixed-rate line cards, for example 100 Gbpsthrough 3.6 Tbps each, with various traffic managementschemes.
The BCM88770 is used to build a variety of networkswitch solutions:
• Over 100 Tbps core/edge switches with singlestagefabric for data center, packet transport, orcarrier network applications.
• Multiple interconnected chassis of differentcapacities, using the BCM88770 two-stagefabric to create a scalable core platform thatdelivers up to 6,000 ports of 100GbE or their40GbE/10GbE equivalents.
