The Parvus® DuraNET 20-10® rugged COTS Gigabit Ethernet switch subsystem is optimized for size, weight, power and cost (SWaP-C) sensitive embedded computer network applications. Featuring advanced Layer 2+ switching with 20 ports of non-blocking 10/100/1000 Mbps connectivity, an integrated management processor, and extremely low power consumption, the DuraNET 20-10 enables reliable local area network (LAN) switching across extended operating temperature ranges (-40 to +71°C) and extreme shock and vibration conditions. For both new platforms and technology refresh programs, the switch features MIL-DTL-38999 connectors in a sealed IP67 (dust and water proof) aluminum chassis. The unit serves as an ideal solution for connecting a large number of IP-enabled embedded devices, including computers, cameras, sensors, and command-and-control equipment deployed in digital networked architectures. To enhance reliability, the unit features no moving parts, a near cable-less internal design, industrial temperature grade components, EMI filtering, and an isolated DO-160/MIL-STD-1275/704 power supply that protects against vehicle voltage surges, spikes and transients.

This fully managed, Layer 2+ GbE switch provides a powerful set of carriergrade networking features, including 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 and radio ports. The DuraNET 20- 10 is based on open architecture, modular embedded technology that can also be factory configured in combo-configurations with CurtissWright’s Parvus DuraMAR IP router subsystem (see DuraMAR 5915 “3X” Series) and/or select DuraCOR mission computers as well as DuraWORX systems – to support Line Replaceable Unit (LRU) consolidation. The unit is qualification tested to extreme MIL-STD-461F and RTCA/DO-160G EMI/ EMC and MIL-STD-810G and DO-160G thermal, shock, vibe, humidity, altitude, and ingress conditions, making it an ideal rugged COTS solution for C4ISR technology refresh and situational awareness upgrade programs requiring highly reliable in-vehicle managed Ethernet switching.
