Shared Memory Network Interfaces

AIT's Shared Memory Network (SMN) interface modules provide host systems with an interface to a high speed (2.125 Gbps) optical data network which can be used to share data, in real-time, between multiple distributed systems. The optical, ring-based network allows data to be shared with deterministic timing and at high data rates to support a wide variety of distributed, real-time, hardware-in-the-loop testing and simulation scenarios.

Key Features

• 2.125 Gbps Optical loop network
• Single-mode and Multi-mode optical interfaces supported
• Up to 256 Shared Memory Network nodes supported
• Up to 200 MByte/sec sustained data rates
• Maximum 500 nS latency between nodes
• Network interrupts supported
• Software Drivers available for Windows (7/8), Linux, LabVIEW Real-Time, and VxWorks
