Broadcom's Next StrataDNX Packs 100 Tbps of Switching Capacity

Broadcom introduced its next generation the StrataDNX ("Dune") family of switch system-on-chip (SoC) devices for optical transport, carrier Ethernet, edge and core routers, data center cloud and enterprise campus market segments. Sampling is underway.

The new switching StrataDNX  silicon, like Broadcom's StrataXGS Trident and Tomahawk switchhing families, are designed to power the next wave of network equipment with a higher port density, lower power consumption and greater subscriber scale in a smaller physical system size.  The company said its StrataDNX breaks new ground as the first to provide 800 Gbps packet processing per device at a high interface bandwidth while integrating a scalable multi-terabit switch fabric, hierarchical traffic manager, external packet buffer memory and advanced packet processing.

The 28 nanometer (nm) StrataDNX family supports pre-standard implementation for 25 and 50 Gigabit Ethernet, enabling direct connectivity to the Broadcom BCM56960 Tomahawk switch SoC. The devices support external DRAM-based packet memory offering up to 300x more traffic buffering compared with on-chip memory, enabling zero-packet-loss in heavily congested networks.  They also offer on-chip hierarchical traffic management ensures per-subscriber bandwidth guarantees, required by carrier networks to deliver on service level agreements (SLAs).

StrataDNX Family Key Features

BCM88370 and BCM88670

  • Up to 800 Gbps forwarding capacity per device
  • Advanced, flexible and configurable packet processor
  • Integrated accelerators for carrier service management
  • Carrier feature support including Ethernet OAM, MPLS, VPLS
  • Integrated hierarchical traffic manager with support for thousands of flows
  • External packet buffer memory supporting DDR4 or GDDR5 DRAM
  • Data center virtual network tunneling including VXLAN, NVGRE and Geneve
  • Support for 10 GE, 25 GE, 40 GE, 50 GE, 100 GE Ethernet port interfaces
  • Support for 200G-400G Interlaken port interfaces
  • IEEE 1588 network timing engine


  • Chassis switch fabric supporting 3.6 Tbps per device
  • Single-stage interconnect for up to 144 BCM88670 devices
  • Dual-plane Ethernet/optical switch fabric
  • Backwards compatible to legacy DNX switch fabric chipsets

"With the addition of our latest StrataDNX products to our switch portfolio, Broadcom is delivering the most comprehensive switching platform in the industry," said Ram Velaga, Broadcom Senior Vice President and General Manager, Network Switch. "These devices will change the way customers build and deploy networking equipment by providing a unique combination of advanced core features at a level of high bandwidth integration never before possible."

In September 2014, Broadcom introduced its next-generation, StrataXGS "Tomahawk" switch, packing 2 Tbps of switching performance in a single chip that is capable of supporting 32 ports of 100 Gigabit Ethernet, 64 ports of 40GE/50GE or 128 ports of 25GE.

The new chip, which represents the 7th generation of Broadcom Ethernet switching silicon, is designed for the programmable fabrics needed in next-gen, cloud-scale data centers. 

The StrataXGS Tomahawk Series is powered by more than 7 billion integrated transistors in 28nm. It supports new 25GE and 50GE protocol standards, and is the first chip to scale to 32-ports of 100G on a single device.

Significantly, Tomahawk implements Broadcom's FLEXGS and Smart-Flow technology, enabling the switch to be software configured for specific policies while preserving deterministic latency. The new design brings a 12X increase in application policy scale compared to previous generation switches, along with increased flexibility of packet lookups and key generation, and rich load balancing and traffic redirection controls. This supports an extensive suite of user configurable functions for flow processing, security, network virtualization, measurement/monitoring, congestion management and traffic engineering.

  • In November 2010, Broadcom introduced its BCM88600 series Ethernet switching silicon designed for modular switching platforms with capacity ranging from 100 Gbps to 100 Tbps. The BCM88600 series integrates the features and functionality of an entire high-performance line card into a single chip, thus enabling a new generation of ultra high bandwidth networking solutions. The new silicon integrates switch fabric technology from Dune Networks (acquired by Broadcom in December 2009 for $178 million) into the Broadcom product portfolio.

ADVA's NFV Strategy Builds on its Carrier Ethernet Portfolio

ADVA Optical Networking is preparing to introduce a number of new network Interface Devices (NIDs) as part of its newly unveiled Network Functions Virtualization (NFV) strategy.  The plan is to leverage the ADVA FSP 150 Carrier Ethernet portfolio to support virtualized customer premise equipment and to create virtualized radio access backhaul networks.

The company said its approach to NFV enables essential functions, such as advanced operations, administration and maintenance, to bridge the gap between virtual and physical network functions and to assure maximum network performance independent of the software appliances running on top. The company’s open architecture is fully standardized and not limited to vendor-specific orchestration solutions.

“The migration to a service-centric network has profound implications on the functions that various network elements need to provide,” said Christoph Glingener, CTO, ADVA Optical Networking. “Replacing single-purpose hardware appliances with network-based software functions is not a small task. In particular the NID-space is undergoing significant change, leading to a new set of functional requirements. Advanced service assurance, security and openness are the cornerstones of successful NFV implementations. Our NFV strategy was defined and sharpened by intense cooperation as well as early demo testing with leading technology providers, operators and also proactive engagement with standards bodies and industry forums.”
