More and more real-world, complex distributed systems are integrated using a Data-Centric Publish-Subscribe approach, specifically the programming model defined by the Object Management Group (OMG) known as the Data Distribution Service (DDS) specification. The DDS Publish-Subscribe approach meets many challenging requirements - supporting large-scale, high-performance, and constrained-bandwidth systems on both powerful machines and embedded platforms. DDS has been used across a wide variety of applications in the defense, robotics, transportation, medical, and financial industries. The following discussion provides a set of architectural "best practices" guidelines that should be applied when using DDS to integrate complex, real-world systems.
Connectors today represent decades of lessons learned. The real magic is how these lessons are blended such that an optimal solution is realized, especially when it comes to modern C4ISR systems.
How to decide which form factor to use for a radar or sonar application? Consider the application's topology: Interconnect topologies that comprise many high-speed connections are well suited to VPX, while applications with more “well-behaved” communications are usually a good candidate for less complex technologies like CompactPCI.
VPX and OpenVPX structures have the ability to add new protocols if need be, which is great news for investors approaching the fabrics of the future.
A trio of VITA standards has emerged to leverage the range of COTS technologies previously hindered by deficiencies in VPX interconnects. Introducing VITA 62, 66, and 67.
No longer just the basic On/Off "workhorse," Discrete I/O interfaces are standing up to the rigors of modern control systems.
Microcontroller and FPGA components join together to become an HPA guardian; an HPA controller capable of the functionality to protect from the VED.
Modern made easy: IT management systems are the newest recruits to join warfighter IT admin teams, simplifying cross-network complexity.
As recent meetings between President Barack Obama and Chinese President Hu Jintao and other U.S. DoD and Chinese officials occur - in addition to the DoD's new Cyber Security Website launch - the need for security is once again highlighted.
Counterfeiters beware: New botanical DNA taggants are acting as a security assurance measure to thwart electronic component counterfeiters' attempts to enter the military supply chain.
