Description：

Broadcom's BCM88470 Series, also known as the StrataDNX® Qumran-AX switch series, canhelp build highly scalable, feature-rich, centralized, fixed or modular aggregation switches toenable cloud-scale networking and Carrier network applications. The BCM88470 devices processup to 300 Gbps traffic, supporting up to 48 full-duplex 10G Ethernet (GE) ports, 16 full-duplex40GE ports, or 4 full-duplex 100GE ports at Layer 2 through Layer 4 with integrated deep-buffertraffic management capabilities, and a fabric interface.

Features：

High performance: 

– 300 Gbps full-duplex switching

• Mesh interface: 

– SerDes interface for back-to-back connection of two BCM88470devices

• Flexible network interface: 

– 1GE, 2.5GE, 10GE, 40GE and 100GE interfaces 

– Support for a mix of OTN (ODU) and ETH ports on the samedevice

• 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, NV-GRE

• Built-in support for data center, carrier and metro Ethernet, and transportapplications

– 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

Applications：
