Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Shown in Figure 2, the lossless process system of the masterslave switchover message in the embodiment of the present invention, including the activestandby state acquisition module being arranged in every piece of Cross Trade and FPGA (Field-ProgrammableGateArray, field programmable gate array), masterslave switchover message lossless process module it is provided with in FPGA, when this system carries out the lossless process of masterslave switchover message, comprise the following steps:
The activestandby state acquisition module of S1: every piece Cross Trade is according to active and standby instruction, it is determined that the activestandby state (master and standby dish) of current Cross Trade, in the present embodiment, No. 1 Cross Trade is master, and No. 2 Cross Trades are standby dish.
S2: master and standby dish synchronism output Ethernet message are to backplane channel, but can only be master messages owing to backboard is sent to business dish, it is impossible to send message that double is identical to business dish, it is therefore desirable to shield, by active and standby signal, the Ethernet message that standby dish exports.
S3: after Cross Trade receives sel (active and standby instruction switching signal, namely standby by main transformer), the masterslave switchover message lossless process module of master and standby dish, it is determined that the position that sel is corresponding with Ethernet message:
If before sel is positioned at the frame head of Ethernet message of master, the Ethernet message of master will not produce broken frame, shields immediately, stops output.
If sel is between frame head and the postamble of the Ethernet message of master, now as shielded master at once, then master can send the broken frame of only frame head, and now the Ethernet message of master continues to export, until sel shields after being positioned at the postamble of Ethernet message, stop output.
If before sel is positioned at the frame head of the Ethernet message of standby dish, the Ethernet message of standby dish will not produce broken frame, is sent to the output interface (postpone a bat and ensure that stablizing of Ethernet message) of standby dish after the Ethernet message of standby dish is postponed a bat by logical process.
If sel is between frame head and the postamble of the Ethernet message of standby dish, now as standby disk startup output then can produce the broken frame of only postamble, therefore needs to shield for the Ethernet message of dish, export after postamble terminates.
S3 is illustrated below by 4 kinds of situations.
One, shown in Figure 3, standby become main: needing the Ethernet message by former standby dish to start output, the Ethernet message of former master stops output；Before being positioned at the former frame head for dish Ethernet message due to sel, will not producing broken frame, therefore the input Ethernet message of former standby dish is sent to output interface after postponing a bat by logical process.
In Fig. 3, clk is clock signal, and fsi is that incoming message frame head indicates, fei is the instruction of incoming message postamble, dvi is that incoming message effectively indicates, dai is data input, fso is the instruction of outgoing message frame head, feo is the instruction of outgoing message postamble, dvo is that outgoing message effectively indicates, dao is that data export.
Two, shown in Figure 4, standby become main: needing the Ethernet message by former standby dish to start output, the Ethernet message of former master stops output；Owing to sel is between frame head and the postamble of former standby dish Ethernet message, broken frame can be produced, therefore the Ethernet message of former standby dish be shielded, after postamble terminates, start output.
Three, shown in Figure 5, standby by main transformer: needing to stop the Ethernet message of former master output, the Ethernet message of former standby dish starts output；Before the sel frame head being positioned at former master Ethernet message, broken frame will not be produced, therefore shield the Ethernet message of former master immediately, stop output.
Four, shown in Figure 6, standby by main transformer: needing to stop the Ethernet message of former master output, the Ethernet message of former standby dish starts output；Owing to sel is between frame head and the postamble of former master Ethernet message, broken frame can be produced, therefore continue to export by the Ethernet message of former master, until postamble shields after terminating, stop output.
The lossless message processing method of the present invention is tested on the IPRAN equipment of Fiberhome Telecommunication Technologies Co., Ltd., and result of the test is to reduce the business dish operation irregularity that broken frame causes, evades possible system risk.
The present invention is not limited to above-mentioned embodiment, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, and these improvements and modifications are also considered as within protection scope of the present invention.The content not being described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
