Siemens Invests in Dune Networks for Scalable Switching Fabric

Siemens Venture Capital has made an equity investment in Dune Networks, a developer of traffic management and scalable switching fabrics. Financial terms were not disclosed.


Dune Networks, which is based in Sunnyvale, California with R&D in Israel, offers a Scalable Architecture for Networking Devices (SAND) chipset provides a non-blocking switching fabric, ingress/egress traffic management and scheduling. The design allows equipment to scale in terms of port rates, port densities and service types, without requiring changes to the core switching fabric and traffic management functions. At the rate level, pipe rates scale from 10Gbps to 40Gbps, 100Gbps and beyond, all interconnecting through the same fabric. At the pipe count level, the number of pipes in the system scale from a single pipe to tens, hundreds and up to 2048 pipes. Dune Networks said its scheduled-fabric chipset would be able to provide backwards and forwards compatibility for diverse services, including TDM, ATM and Ethernet.

  • In June 2004, released a 20Gbps and a 10Gbps full-duplex traffic manager device as part of its Scalable Architecture of Networking Devices (SAND) chipset architecture. The devices feature one or two SPI4.2 interfaces and a switch fabric interface. Dune Networks said its traffic manager devices provide a unique ability to interconnect and communicate via the fabric interface allows any system of any size to provide end-to-end rate and weight guarantees for packet flows. Such an arrangement enables end-to-end rate guarantees of packet flows across a complete system and not just locally within a line card. This scheme enables the system to provide specific Committed Information Rate (CIR) and Peak Information Rate (PIR/EIR) for a packet flow from an ingress port (e.g. access port) to an egress port (e.g. uplink port).


  • Dune Networks is headed by Eyal Dagan (CEO), who previously was a co-founder and CEO of Charlotte's Web Networks, a privately held company focused on developing high-end core equipment for next generation optical networks. Before founding Charlotte's Web, Eyal was the Vice President of R&D for the Switching Division of MRV Communications
