Dune Networks intros programmable metro Ethernet and access traffic manager devices

JANUARY 21, 2008 -- The FAP21V and FAP11V offer enhanced traffic management functionality addressing edge functionality of metro Ethernet and access networks.

JANUARY 21, 2008 -- Dune Networks (search for Dune Networks) has introduced two new devices that expand the company's SAND chipset offering. The FAP21V and FAP11V offer enhanced traffic management functionality addressing edge functionality of metro Ethernet and access networks.

The FAP21V and FAP11V are designed to provide 20 Gbits/sec and 10 Gbits/sec full-duplex programmable traffic management with an integrated SAND fabric interface. The devices provide one (FAP11V) or two (FAP21V) SPI4.2 interfaces to the line side, DRAMs for deep packet buffering, and serial links for fabric and mesh interconnection.

The FAP devices' unique abilities to interconnect and communicate via the SAND fabric or a mesh, provides a distributed TM functionality across a switching system, according to Dune Networks. Furthermore, they may be used as standard standalone ingress and/or egress traffic management devices. A FAP11/21V device provides fully programmable traffic management services, addressing the standards and implementation agreements of the MEF, IETF DiffServ, and DSL Forum TR-059/TR-101, according to the vendor.

FAP11/21V programmable scheduling includes:


  • fully programmable scheduling hierarchy
  • support for uneven hierarchical schemes
  • single and dual bucket shaping enabling fully specified CIR/CBS and EIR/EBS bandwidth profiles
  • simultaneous shaping at every level and entity in the hierarchy
  • system-aware WRED, enabling WRED decisions to be based on full system view.

"Dune Networks' technological lead has enabled it to win major designs at Tier-one telco and enterprise OEMs," said Jag Bolaria, senior analyst with the Linley Group. "Continuing this trend, the FAP11/21V programmable traffic manager meets the increasing service requirements at the edge and within metro networks."

"The SAND chipset is the only solution enabling system vendors to build a platform that can scale port rates, port counts, and service schemes. This extends the life cycle of the product line to 10+ years. The new FAP21V and FAP11V devices are prime examples of how to effectively scale the services of a platform while maintaining backward compatibility with all other line cards," said Ofer Iny, CTO of Dune Networks.

The FAP11V and FAP21V devices are sampling now with volume production in Q2/08.
