Real-Time LAN Solution Integrating Multiple Vendors
To address the needs of users wanting a real-time network
incorporating multiple computer vendors, an Ohio-based company
introduced SCRAMNet (TM).
SCRAMNet (Shared Common Random Access Memory Network) is a high
speed, real-time shared memory local area network. SCRAMNet is not a
token-passing ring like other commercial products. More precisely, it
is a register-insertion ring where each node places the network data
into an out-going FIFO. Each node consists of a host interface,
network interface circuitries, and shared memory (8K min - 2M max).
This memory is replicated memory, where every node on the ring has the
same contents. This memory is viewed by the host CPU as "just
memory".
Major Features:
- 150 Megabyte/second data rate
- Fiber Optic Link
- Data Filtering (avoids unnecessary traffic)
- Programmable Byte Swapper
- No Software Overhead
- Multiple Bus Interfaces (VME,QBus,UNIBus,NuBus,Multibus,Selbus etc.)
- Per-location Interrupt Passing
- Automatic Error Recovery
- 200 - 600 nsec Node Latency
- 700m Max Node Separation
- Gateway Node to interconnect to other low-speed message passing networks
such as Ethernet and FDDI
