Architecture
The GE Intelligent Platforms RCNIC-
A2PAU4 is a high performance interface for
monitoring, generating or analyzing full-
bandwidth AFDX/ARINC 664 protocol traffic.
GE Intelligent Platforms’ exclusive pipeline
architecture maximizes packet throughput
using parallel controllers and efficient DMA
transfers, thereby avoiding the bottlenecks
of CPU-based interface solutions.
Configurable as either one dual-redundant
AFDX/ARINC 664 interface or two
independent ports, users have complete
access to all frame and header data.
Each incoming packet is tagged with a 20
nsec resolution, 64-bit time-tag. Real time
traffic generation is highly accurate. An
IRIG-B receiver/generator is included for
synchronization to external IRIG-B time
sources and for synchronizing multiple
RCNIC-A boards. In addition, I/O triggers,
error detection/injection, BIT, and link/
protocol level statistics are provided.
AFDX/ARINC 664 Part 7 Performance
Multiple RCNIC-A2APU4’s in the same PC
have been benchmarked at full bandwidth
supporting all channels with 2000 VLs
(virtual links), multiple ports on each VL and
minimum payloads (17 bytes).
Advanced Software Support
The RCNIC-A2PAU4 comes with all the
software development tools needed for user
application development at no extra charge.
The Cpcap packet capture library provides
a complete set of functions for transmitting
and receiving Ethernet frames.
Frames from multiple ports can be logged
or replayed using the open-source ntar log-
file format. AFDX-A implements the AFDX/
ARINC 664 Part 7 protocol stack including
end systems, redundancy management,
virtual links, and ports. An advanced XML-
based configuration file format is used to
specify end systems.
