The GT-xxTD provides two independent channels of 1000Mbps Ethernet. A totally hardware based solution the GT-xxTD is a Layer 1 device and operates at wire speed for optimal performance. Desktop or rack-mountable the GT-xxTD takes data security to new levels.
- No vulnerable software, firmware, memory or buffers that may otherwise be exploited.
- Tamper proof casing
- Unidirectional fibre links transmit and receive diodes
- Guaranteed one way transmission
- No physical return path
Technical Notes
Configuring ARP for use across Data Diodes
Address Resolution Protocol (ARP) is a protocol used to ascertain the hardware address or Media Access Control (MAC) address from an IP address. Typically a sending station knows the destination IP that they wish to send to but does not the MAC address. Before communication between the 2 hosts can occur an ARP request is sent to discover the destination MAC address. The ARP request is directed to the destination IP address using a MAC broadcast address FF:FF:FF:FF:FF:FF. All devices on the subnet receive this broadcast but only the destination with the correct IP address will respond.
