StrataDNX® Jericho switch series

Currently Viewing:

Broadcom'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.

The 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:

• 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 BCM88670 and BCM88770 fabric to create a scalable core platform, delivering up to 6,000 ports of 100GbE or their 40GbE/10GbE equivalents


High performance:

  – 720 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
