ASHBURN, Va. Curtiss-Wright Defense Solutions has been chosen by a leading defense system integrator to provide its embedded Security IP module technology, supplying its XMC-528 mezzanine card to add security protection to an existing system within a Department of Defense (DoD) end-state application. 

For many years, military-system designers relied solely on direct attached storage (DAS) devices when they needed to deploy data storage on military platforms. These devices are embedded within or directly attached to the computers, such as single-board computers (SBC) on a platform. When a DAS device is used, only the specific SBC it’s attached to can access the stored data-at-rest (DAR). With Ethernet becoming commonplace on modern platforms, network attached storage (NAS) devices (also known as network file servers [NFS]) have emerged as an important alternative for deployed data storage. With NAS, stored DAR can be made available to any client devices on the Ethernet network. NAS and DAS are often used in combination to meet all program, platform, and application requirements. However, in those cases where it makes sense to use only a DAS or a NAS device, it’s useful to understand how they differ.

The vision of hardware interoperability at the tactical edge, from air platforms to ground vehicles to base stations, is now being realized. Because MOSA [modular open systems approach] is an approach and not itself a standard, solutions that support this vision can be achieved through many different means as long as interfaces and communications protocols are based on open standards. There remains a key area to address, though, to achieve seamless interoperability between heterogeneous systems. Consider, for example, the Sensor Open Systems Architecture (SOSA) Technical Standard: While most aspects of sensor processing system architectures are well-defined within SOSA, one area that has not been rigidly defined is the network configuration and operational environment of individual cards and modules.

For rugged DSP [digital signal processing] processor cards, it is important to have a balance between processor performance, memory bandwidth, I/O bandwidth, and ruggedization. Deficiencies in any of these attributes will limit the achievable performance. Due to limited real estate available on 3U OpenVPX boards, designers and users must make tradeoffs on which dimensions to maximize and/or minimize.

A software-defined WAN (SD-WAN) can establish a data fabric capable of dealing with any tactical edge scenario where reliable WAN is needed.

Many defense and aerospace processing systems are upgraded or refreshed rather than replaced for cost efficiency and to reduce out-of-service time.

Secure wireless communications (SWC) technology for vehicle-to-vehicle (V2V) and vehicle-to-end user device (V2E) communication is useful for tactical environments as it improves network flexibility and operational maneuverability while reducing management complexity and cost. As seen in the commercial market, securely implementing wireless local area network (WLAN) communication opens the door for innovative solutions to existing and future operational challenges.
