BCM88670数据手册Broadcom中文资料规格书

描述 Description

\\r\\rBroadcom's BCM88670 Series, also known as the StrataDNX® Jericho switch series, can help build highly scalable, feature-rich, modular chassis or aggregation switches to enable cloud-scale networking and Carrier network applications. The BCM88670 device processes up to 720 Gbps traffic, supporting up to six 100G full-duplex ports at Layer 2 through Layer 4 with integrated deep-buffer traffic management capabilities, and a fabric interface.
rThe BCM88670 series is the sixth generation of the Dune scalable switching product line. Together with the BCM88770 fabric element (FE) device, it is used to build a variety of network switch solutions:
r
• Over 100 Tbps core/edge switch with singlestage fabric for data center, packet transport, or carrier network applications
r
• Multiple interconnected chassis of different capacities that use BCM88670 and BCM88770 fabric to create a scalable core platform, delivering up to 6,000 ports of 100GbE or their 40GbE/10GbE equivalents\\r\\r\\r
