Embodiment Construction

[0047] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] The embodiment of the present invention provides a system for improving the transmission efficiency of the FC-AE-1553 bus, and realizes network switching between the NC and multiple NTs, and the network switching is interleaved. The NC sends command sequences to multiple NTs in turn without completing the network exchange with the current NT, and initiates network exchanges with multiple NTs interleavedly. The NC receives the status sequence returned by a certain NT, and ends the network exchange with the NT. The sending and receiving of NC work in parallel and work in full-duplex mode.

[0049] Such as figure 1 , figure 2 As shown, a system for improving FC-AE-1553 bus transmission efficiency provided by an...

Abstract

The invention relates to a system for improving the transmission efficiency of FC-AE-1553 bus, and belongs the technical field of computer communication. On the basis of an original communication mode, a network controller NC can make network exchange with multiple network terminals NT in an alternative access manner, full duplex is realized, the transmission interval of a sequence in the bus is reduced, the bandwidth utilization rate is improved, and the transmission efficiency of FC-AE-1553 bus is improved.

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...
