The first choice of present avionics system network.As avionics network system integrated degree is strengthened, popularization, system knot
Structure is become more sophisticated, and real-time monitoring, record and the Correct Analysis of onboard networks data are had very important significance.
The monitoring record of current FC data and analysis, most of instrument of use is all external product, mainly there is the U.S.
The Xgig FC analyzers of JDSU companies, U.S. Absolute Analysis Investigator FC analyzers, LeCroy
FC Protocol Suite etc., these equipment can realize the parsing to fiber channel protocol substantially, also support multi-protocols, many
The data acquisition test analysis of passage, multi tate, but mainly include the problem of exist：Only memory on board is supported to carry out FC data
Keeping records, but memory on board is less, is unfavorable for expanding so that the monitoring record of FC data and analysis means are single, no
Possesses real-time.
The content of the invention
The technical problems to be solved by the invention are that prior art is single to the monitoring record and analysis means of FC data, no
Possesses real-time, it is therefore intended that optical-fibre channel flow analysis recording method and device under a kind of aviation electronics environment are provided, make FC
The monitoring record of data is not single with analysis means, and with real-time, while saving substantial amounts of memory headroom.
The present invention is achieved through the following technical solutions：
Optical-fibre channel flow analysis recording method, comprises the following steps under a kind of aviation electronics environment：
Step 1：FC monitoring analysis local terminal or the generation of FC monitoring analysis remote terminal start monitor command, FC monitoring point
