The TCDS-MPP is Owl’s premiere mobile/tactical hardware-enforced one-way transfer solution for data streaming and/or file transfer.
Raise-the-Bar Ready
It combines Owl Scowt’s Raise-the-Bar (RTB)-ready ruggedized hardware platform and Owl’s Multi-Protocol Platform (MPP) Cross Domain Solution (CDS) software platform. Owl’s CDS-MPP software is designed to address RTB’s One-Way Transfer (OWT) design patterns. The Owl Scowt hardware platform is available in two (2) configurations:
- Scowt – active cooled, rack mounted
- Scowt – conduction cooled, frame or shelf mounted
These configurations are reduced size, weight, and power (SWaP) dual-processing nodes, separated by Owl’s patented hardware-enforced one-way transfer diode, that support dataflow bandwidth up to 1 Gbps for UDP and TCP content streaming and file transfers.

Key Features
The Owl-Scowt Compact is a dual-node platform that includes two processing environments separated by Owl’s patented hardware-enforced, one-way transfer diode. Each processing environment includes an instance of Owl’s CDS-MPP software that is based on a STIG compliant, CLIP enforced EAL4+ Red Hat Enterprise Linux (RHEL) foundation. It’s capable of scanning and file validation filtering for file transfer data flows and filter protocol header and payload for streaming dataflows.
The solution’s combined technologies provide data flow protection for the highest threat environment connections.
- Latency -3ms to 8ms depending on the filter
- UDP-based data streaming and TCP-based file transfers or data streams
- Up to four data flow types: filtered files, non-filtered TCP streams, Filtered UDP unicast and multicast streams, UDP broadcast
- RFTS and TCP/UDP Sockets

What’s Included:
