Description

technical field

[0001] The invention relates to the technical field of computer communication, in particular to a system for improving FC-AE-1553 bus transmission efficiency. Background technique

[0002] FC-AE-1553 is a standard developed by the Aerospace Electronics Subcommittee of the Fiber Channel Standardization Organization. This standard maps the MIL-STD-1553B bus protocol on the FC-4 layer, taking advantage of the advantages of fiber channel transmission efficiency, low delay, long transmission distance, and high reliability, and is compatible with the original MIL-STD-1553B equipment terminal .

[0003] A typical FC-AE-1553 network is composed of one FC-AE-1553 network controller (NC), multiple FC-AE-1553 network terminals (NT), FC switches and optical fibers, such as figure 2 shown. NC is the decider and command initiator of network interaction. NT is a network terminal and command executor. Taking the NC-NT direction as an example, the network exchange method...
