Thinklogical VX80
The TOE provides remote connections from a set of shared computers to a set of shared peripherals. The switching capability of the TOE is used to connect ports on a particular computer to a particular peripheral set. The corresponding electronic signal from a computer port is transformed into an optical signal by the Velocity extender, transmitted through an optical fiber, switched by the TOE to another optical fiber, and then transformed back to an electronic form by the Velocity extender. The resulting signal is used by the shared peripherals.
The TOE provides a capability to dynamically change the switching configuration to connect a particular computer to a particular peripheral set.
The TOE enforces secure separation of information flows corresponding to different switched connections. The corresponding Data Separation Security Policy is the main security feature of the TOE.
