High-Density 100 Gigabit Ethernet StrataDNX® Jericho+ Ethernet Switch Series

Currently Viewing:

Broadcom's BCM88680 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 BCM88680 device processes up to 900 Gbps traffic, supporting up to nine 100G full-duplex ports at Layer 2 through Layer 4 with integrated deep-buffer traffic management capabilities, and a fabric interface.
The BCM88680 series is the seventh 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:
• Over 100 Tbps core/edge switch with singlestage fabric for data center, packet transport, or carrier network applications
• Multiple interconnected chassis of different capacities that use BCM88680 and BCM88770 fabric to create a scalable core platform, delivering up to 9,000 ports of 100GbE or their 40GbE/10GbE equivalents


High performance:
– 900 Gbps full-duplex switching
• Fabric interface:
– SerDes interface to Dune's Fabric Element (BCM88770)
– Fabricless (without the fabric element) configurations of up to three devices
• Flexible network interface:
– 10GbE, 25GbE, 40GbE, 50GbE, 100GbE interfaces
– Support for a mix of OTN (ODU) and ETH ports on the same device – 400GbE ready
• Traffic manager:
– Deep buffering, GDDR5/DDR4 DRAM-based
– Large on-chip buffers
– Hierarchical QoS
– Programmable, hierarchical scheduling
• Flexible and microcode-programmable packet processor:
– Bridging, routing, MPLS, VPLS, L2VPNs, L3VPNs, OAM
– Data Center Tunneling Encapsulations including VXLAN and NV-GRE
• Built-in support for data center, carrier and metro Ethernet, and transport applications
– Large on-chip tables with off-chip expandability
– OAM accelerator engine
• OTN and TDM support:
– Dedicated low delay pipe for TDM/OTN traffic
– Fixed and predictable latency data path for TDM systems
– Unified fabric for OTN and packet
