Description

technical field [0001] The invention relates to an FC network emulator, in particular to an FC network emulation terminal for realizing multi-channel emulation. Background technique [0002] The FC network emulator can simulate the data communication process of the airborne network terminal. It generates a series of various types of messages through the upper layer, such as emergency messages, periodic messages, event messages, large data block messages, network management messages, to simulate various communication events in the airborne communication network communication, and compose these messages Different FC data frames are sent to the fiber channel through the FC emulation board. At the same time, the received FC data frame is transmitted to the computer through the board for processing and analysis. The system can well simulate the data communication between devices on the airborne network, and the simulation can provide reliable basis and important data for refere...
