Board-Level Ethernet Switches Connect with Military Needs

Rugged Ethernet switch boards enable have become entrenched as solutions for both military networking and as an interconnect fabric in compute-intensive applications.

JEFF CHILD, EDITOR-IN-CHIEF

Long gone now are the days when the U.S. DoD was considering various different networking technologies. Today there’s no question that Ethernet has become the standard for connecting the IP-based components of autonomous vehicles, robots, and other military and harsh mobile applications. Ethernet switch boards are the linchpin needed to connect those systems. The large bandwidth and exceptional scalability of the 10 Gbit Ethernet network enables systems developers to seamlessly scale up with increasing channel count and bandwidth.

Aside from using 10 Gbit Ethernet for networking, the military has followed on to embrace it as a high-speed data transfer mechanism for demanding military sensor interfacing and processing. It offers a standards-based server solution that takes advantage of processing power gain and market pressures for driving down processing costs. A 10 Gbit Ethernet network simplifies system architecture and provides easy partitioning of data acquisition and data processing, by separating the sensitive analog mixed signal front end from the digital back end.

Even as a fabric choice, Ethernet has taken its place as favorite choice fabric in compute-intensive military applications like sonar, radar or any application that networks sensor arrays together. Ethernet offers nearly limitless synchronized scalability by simply adding fibers for additional 10 Gbit Ethernet links. Ethernet allows simplified acquisition devices to be placed near the antenna that pipes the data to processing platforms in a sheltered location. A 10 Gbit Ethernet system also handles real-time bandwidth in excess of GHz on a continuous and sustained basis.

As the round up on the next four pages show, Ethernet switches in form factors such as VPX and CompactPCI PICMG 2.16 serve as communications backbones for moving massive amounts of data around tightly coupled processing or I/O data concentrators, typically found in military, aerospace and spacecraft applications. Many operating at full wire speed, these non-blocking switches provide high-speed connectivity and traffic management for streaming video, audio and data. Note that this roundup is specifically on board-level Ethernet switch products. There’s a rich set of new products in the box-level Ethernet switch category but that falls outside the scope of this roundup.

An example of Ethernet being used by the military in embedded systems, is the Navy’s Ship to Shore Connector (SSC) craft. Last year North Atlantic Industries received a contract to provide the Data Acquisition Unit for the Ship to Shore Connector (SSC) (Figure 1). The SSC is the successor to the Navy’s extremely versatile Landing Craft Air Cushion (LCAC) vehicle, which is nearing the end of its expected service life. NAI’s Sensor Interface Unit (SIU35) offers modularity and adds distributed interfaces over Ethernet for custom solutions using COTS products. As part of the Data Acquisition Unit (DAU) system, the SIU35 enables population of each board with function-specific modules. As part of NAI’s modular COSA architecture, a selection of up to 15 different functions can be selected from a broad assortment of low-power, high-density modules.
