TCP Packet Transfer System

Secure TCP Technology
Secure TCP Packet Transfer System (TPTS) provides a TCP application level protocol bridge across our patented, hardware based security to support one-way communications. Secure TPTS hardware uses custom device drivers for the communication cards and the low level Asynchronous Transfer Mode (ATM) communication protocol to support high-speed (155 Mbps) one-way transmission.
How it Works
The Owl DualDiode® hardware provides a secure data transfer between two network servers that are not otherwise directly connected, either physically or logically. The transfer is one-way, significantly hardening the security of the communications link over conventional networks. The one-way transfer is physically enforced at both ends providing protection at both the source and destination of information flow. The source (or “send”) hardware is identified by Blue Owl logos. The destination (or “receive”) hardware is identified by Red Owl logos.
The TCP Packet Transfer System (TPTS) uses the TCP/IP (Transmission Control Protocol/Internet Protocol) as a user interface to our one-way system. TCP/IP is the basic communication protocol of the Internet. It can also be used as a communications protocol in a private network on either an intranet or an extranet. TCP/IP is a two-way protocol, however, our system strips off all headers and transfers only the payload across the one-way link. A TCP/IP client program connects to Owl’s BLUE machine—operating as a TCP/IP Server.
