Data receiver switching port 4 is processed by transferring to multi-protocol data processing module 202 after data protocol type judging module 201 is judged after receiving data, data after processing are back to data receiver switching port 4 and process, and export data output switching port 5 to by exchanging after scheduler 3 is checked processing after the wherethrough reason.Described Prestige Management module 102 is controlled AV prestige counter 103 and ASM prestige counter 104.Prestige Management module 102 has prestige and consults and the Prestige Management function; The prestige negotiation functionality is: data receiver switching port 4 coordinates Prestige Management module 102 to provide respectively independently ASM message credit value and AV message credit value for logging device, and AV message credit value and the ASM message credit value consulting to obtain are returned to logging device; The Prestige Management function is: the count value number of controlling ASM prestige counter 104 and AV prestige counter 103 by the variation that monitors data receiver switching port 4 data buffer area 101.The ASM data buffer area 1012 of data buffer area 101 is connected with multi-protocol data processing module 202 with AV data buffer area 101, being used for that the data of multi-protocol data processing module 202 are put into respectively corresponding ASM data buffer area 1012 or AV data buffer area 1011 processes, exchange scheduler 3 is checked ASM data buffer area 1012 and AV data buffer area 1011, and the data that needs are forwarded or exchange export 5 to data output switching port.
The control method of a kind of aviation electronics optical-fibre channel multiprotocol controller that the present invention proposes comprises step:
Step 1: data receiver switching port 4 monitors the logging request of other beaching accommodations (as radar, fire control computer or head-up indicator etc.), if do not receive that the request that logs in of beaching accommodation continues to monitor, as shown in Figure 3, if receive after the logging request of beaching accommodation that carrying out port prestige by Prestige Management module 102 consults, and returns to logging device with AV message credit value and the ASM message credit value consulting to obtain.In negotiations process, data receiver switching port 4 provides respectively independently ASM message credit value and audio message credit value for logging device;
Step 2: monitor whether data receiver switching port 4 has optical-fibre channel data (being abbreviated as the FC data) to arrive, as shown in Figure 4, if while having the FC data to arrive, with FC transfer of data protocol type judge module at the most, multi-protocols type judging module 201 is checked frame head type of message territory, by the type of optical-fibre channel frame head (FC frame head) judgement FC message;
Step 3: the multi-protocol data processing module is carried out separate, stored and virtual line-up in conjunction with the data receiver switching port to the dissimilar data that arrive, as shown in Figure 4, if the FC message that arrives is ASM message, multi-protocol data processing module 202 puts it in the ASM data buffer area 1012 of data receiver switching port 4 data buffer area 101, destination address according to ASM message under the scheduling of switch scheduler 3 deposits corresponding ASM VOQ 1012-2 in, and the count value of the ASM prestige counter 104 of Prestige Management module 102 management simultaneously adds 1; If FC message is AV message, multi-protocol data processing module 202 puts it in the AV data buffer area 1011 of data receiver switching port 4 data buffer area 101, destination address according to AV message under the scheduling of switch scheduler 3 deposits corresponding AV VOQ 1011-1 in, and the count value of Prestige Management module 102 management AV prestige counters 103 adds 1 simultaneously;
Step 4: as shown in Figure 5, exchange scheduler 3 checks whether the ASM data buffer area 1012 of data receiver switching port 4 is empty, if not empty, ASM virtual cache formation 1012-2 in ASM data buffer area 1012 is exchanged and forwards scheduling, forward or exchange to data output switching port 4, the count value of Prestige Management module 102 control ASM prestige counters 104 subtracts 1 simultaneously, then exchanges scheduler 3 and returns to the ASM data buffer area 1012 that continues to check data receiver switching port 4., if exchange scheduler 3 checks that the ASM data buffer area 104 of this data receiver switching port 4 is empty, check AV data buffer area 1011.If AV data buffer area 1011 is not empty, the AV virtual cache queue message 1011-1 of this AV data buffer area 1011 exchanged the forwarding scheduling, forward or exchange to data output switching port 4, simultaneously Prestige Management module 102 count value of controlling AV prestige counters 103 subtracts 1, then exchanges scheduler 3 and returns to the AV data buffer area 1011 of the data buffer area 101 that continues to check data receiver switching port 4; If AV data buffer area 1011 is empty, this data receiver switching port 4 is not carried out any processing, continue to check the ASM data buffer area 1012 of data receiver switching port 4.
Receive 4 pairs of message datas that receive of exchanges data port and be stored in different data buffer area 101 according to data type, simultaneously Prestige Management module 102 and control respectively AV prestige counter 103 and ASM prestige counter 104 for AV message and ASM message and carry out the traffic management of data.Dissimilar message is distinguished management, make the difference scheduling to message data become possibility.
Beaching accommodation and data receiver switching port 4 consult to obtain simultaneously AV message credit value and ASM message credit value.When a large amount of AV transmission of messages is arranged, only take the credit value of AV message in data receiver switching port 4, when a large amount of AV message are transmitted, when having ASM message to transmit, still can instantaneous transmission.While having prevented that AV message and ASM message from sharing credit value, after big data quantity AV transmission of messages took whole prestige, ASM message need to be waited for the complete rear shortcoming that just can transmit of AV transmission of messages.
