Data Device Corporation (DDC) a major company in data networking technology for military applications recently announced the introduction of its GigExtreme series of intelligent Gigabit Ethernet Network Access Controllers. DDC has designed the GigExtreme ET- 71000 gigabit ethernet card from the ground up to meet the demanding challenges of flight critical military applications and harsh military environments. ET-71000 cards feature a dual redundant architecture with autonomous failover or dual independent channels, supporting 10/100/1000Base-T or 1000Base-SX physical layer options.

The ET-71000 series PMC cards include a TCP/IP Off-load Engine (TOE) that implements the full TCP/IP protocol stack, freeing valuable host processor bandwidth. The processor- based TOE implementation uses DDC developed firmware for the TCP/IP protocol engine, data traffic management and redundancy management functions. High-speed data transfer is supported using a standard TCP/IP sockets interface. “Our product development objective was to provide a design that enables the deterministic performance required by mission critical applications while maintaining standard software interfaces”, said Thomas Cheng, Marketing Manager at DDC for High Speed Networking Components.

The ET-71000 architecture reportedly provides the flexibility to meet the system requirements for embedded, real-time, military applications. The architecture is not sensitive to rapidly changing commercial market forces that can result in shortened life cycles. Instead, DDC gigabit ethernet technology has been designed to meet the multi-decade life cycle demands of military/aerospace programs.

The ET-71000 series of conduction cooled gigabit ethernet network access cards operate over a wide -40 to +85°C temperature range and are available with front panel 1000Base-T and optical 1000Base-SX connections or PMC rear connections for 1000Base-T and 1000Base-X SERDES signals. DDC supplies the software driver for VxWorks and plans to support other operating systems later this year.
