Shared Memory Network

The SCRAMNet Network (Shared Common RAM Network) is a replicated shared-memory communication system designed for use in real-time computer systems. It is optimized for the high-speed transfer of small packets of data among computers when low-latency data transmission is required. It is suited for applications including simulation, telemetry, robotics, data acquisition, instrumentation and control, and virtual reality.

Memory writes to the replicated shared memory at one computer are instantly sent to all other replicated shared memories on the network at 150 Mbits/sec via high-speed fiber optic or coaxial cable. There are no bus connections, protocols or non-deterministic message crashes. Data latency is 250-800 nanoseconds per node. Up to 256 nodes (each separated by up to 3500 meters) can be contained on a single fiber optic ring, with both data transmission and computation occurring simultaneously.
