Curtiss-Wright Corporation has introduced what it claims to be the industry’s smallest and lightest rugged 8-Port Gigabit Ethernet (GbE) Switch subsystem, the Parvus DuraNET 20-11 . Designed for highly miniaturized rugged solutions, this fully-managed Layer 2+ switch is meant to define a new class of ultra-small form factor network components. It is optimized for deployed defense, aerospace, and civil ground vehicle and aircraft platforms that require extremely low size, weight, and power (SWaP). Based on a combination of stacked PCB layout and system-on-a-chip (SOC) technology, the DuraNET 20-11 is delivers advanced network switching in an unprecedented miniature form factor.
Weighing less than 0.50 lbs., this line-replaceable unit (LRU) requires <10 cubic inches of volume and consumes < 8.0 Watts of power. The highly rugged unit speeds and simplifies the integration of modern network architectures into manned and unmanned platforms that must endure harsh environmental and noisy electrical conditions (e.g. high altitude, extreme shock & vibe, extended temperatures, humidity, dust & water exposure, noisy EMI, dirty power). It provides system integrators with an extremely reliable Local Area Network (LAN) switching solution. It’s targeted for connecting Ethernet-enabled embedded devices, including computers, cameras, sensors, and command-and-control equipment deployed in digital networked architectures at the network edge.
The DuraNET 20-11 provides carrier-grade Ethernet software Level-2+ management features including support for IEEE-1588v2 Precision Timing Protocol (PTP). Able to perform optimally in the harshest conditions, this rugged LRU is designed to comply with MIL-STD-704F, MIL-STD-1275D, MIL-STD-461F, and RTCA/DO-160 for civil and military use. The compact subsystem is fully sealed, has no moving parts supports, and supports extended temperature operation (-40 to +85C) and resistance to high shock/vibration, humidity, altitude, and dust/water ingress. MIL circular-type connectors make the DuraNET 20-11 ideal applications where electromagnetic compatibility (EMC) is critical for Ethernet, power, console, and zeroize signals. It also features integrated EMI/power filtering to meet power input voltage, spikes, surges, transients.
The DuraNET 20-11’s advanced network switch features include support for IPv4 and IPv6 multicast traffic, Virtual Local Area Networks (VLANs), port control (speed / mode / statistics, flow control), Quality of Service (QoS) traffic prioritization, Link Aggregation (802.3ad), SNMPv1/v2/v3 management, secure authentication (802.1X, ACLs, Web/CLI), redundancy (RSTP/MSTP), precision timing (IEEE-1588v2), port monitoring, IGMP Snooping, Built in Test (BIT), and data zeroization. The unit also supports Layer 3 IPv4 / IPv6 unicast static routing for IP routing to attached WAN / radio ports.
