The Fox DataDiode software supports one-way UDP traffic. This feature enables users to send syslog messages, SNMP traps, video streams etc. from the black to the red network. Since different ports can be used for UDP data transfer, setting these port numbers is part of the configuration. The port numbers for the BLACK and RED proxy must be the same, but the RED proxy offers the possibility to forward data to different port numbers on the destination target.
As illustrated in the above figure, two clients send simultaneously UDP streams through the Fox DataDiode solution. On the BLACK proxy the administrator can configure the source IP address and source port. On the RED proxy the target IP and target port can be configured for each stream individually.
Streaming through the Fox DataDiode can reach throughputs up to 800 MBits/s.
