The hardware for an Eaglet subnet partitioner is a workstation similar to the G box with two network interfaces running the same gateway control software. The A box communicates with an Eaglet in an encrypted protocol. There is no disk copy of the authorization file on an Eaglet. Like the G box, an Eaglet repackages IP packets to hide the implementation details of the subnet from any potentially malicious eavesdropping.
An Eagle box can control any number of Eaglets.
