From above-mentioned description as can be known, basic ideas of the present invention are: under existing hardware constraints, systems soft ware provides the ILC message real-time testing mechanism, if find that the TDM passage receives or transmission ILC message is not smooth, this situation shows that the TDM passage is in malfunction, the time-division switching chip of space switching chip port or the correspondence of then resetting is tentatively to attempt to recover port failure.Continuous reset space switching chip port or time-division switching chip repeatedly after, still under the situation of crash, then report and alarm is notified the attendant timely handling failure to the TDM passage; Switch arbitration by main with the comprehensive judgement of space switching chip simultaneously, whether decision is initiated to lead with the space switching chip is switched or leads and switch with the time-division exchange chip, make every effort to the TDM link switchover of current inefficacy to available backup TDM link, realize the redundancy of TDM passage.
Below in conjunction with shown in Figure 5, the embodiment of technical scheme of the present invention is described.
The space switching chip generally has 32 ports, and 32 SBI336S passages are promptly arranged, and can dock with 32 time-division switching chips.The time-division switching chip provides two-way SBI336S passage, comprises service aisle WP and protection passage PP, can dock with primary, spare space switching chip respectively.
The hardware interconnection mode of space switching chip and time-division switching chip as shown in Figure 5 under the backup mode.In the drawings; mutually redundant time-division switching chip is fixedly attached on the identical Pn port of space switching chip; wherein main continuous with the service aisle of time-division switching chip with the space switching chip, the protection passage of standby space switching chip and time-division switching chip links to each other.Realize " dual transmitting and receiving " for the ILC message, that is: the ILC of space switching chip message transmitting party to, the output of space switching chip is divided into two parts through bottom layer driving, delivers to the port of active and standby time-division switching chip respectively; At the ILC of space switching chip message receive direction, active and standby time-division switching chip is all delivered on the corresponding space switching chip port simultaneously, select (seeing that M_Select selects door among the figure) by bottom layer driving according to the activestandby state of time-division switching chip, and then deliver to the port of space switching chip, that is to say, the space switching chip port is only selected the main ILC message of sending with the time-division exchange chip, and standby time-division switching chip is sightless for the space switching chip.
The ILC detection scheme specifically describes as follows:
Step 1, timing s millisecond sends and receives the ILC message mutually between time-division switching chip and the space switching chip, and carries out the ILC message and detect.For the space switching chip, the ILC of open primary, spare space switching chip channel detects in real time respectively.For the time-division switching chip, the ILC of open working passage, protection passage detects in real time respectively.
Step 2 detects at the appointed time under the situation less than the ILC message and resets.
The time-division switching chip is responsible for regularly the sending direction that the s millisecond detects the ILC message from space switching chip veneer to the time-division exchange chip.If time-division switching chip veneer can not receive the ILC message continuous n time, the time-division switching chip of the local terminal that then resets is under the situation that continuously m time-division switching chip that resets is still invalid, by the reset space switching chip port of opposite end of ethernet channel request.
Space switching chip veneer is responsible for regularly the sending direction that the s millisecond detects the ILC message from the time-division switching chip to the space switching chip.If space switching chip veneer can not receive the ILC message continuous t time, the space switching chip port of the local terminal that then resets, and by the reset time-division switching chip of opposite end of ethernet channel request.As shown in Figure 5, main with under the situation of time-division exchange chip by selecting door to select, the main time-division exchange chip of using of the opposite end that resets.
Wherein, main with the ILC detection failure counting of record main board on the space switching chip veneer to each time-division switching chip single plate bidirectional.Collect on space switching chip veneer and safeguard active and standby main with space switching chip veneer, active and standby failure count with all ILC transmitting-receiving detections on the time-division exchange chip veneer.
When the time-division switching chip is sent the request of the space switching chip port that resets, space switching chip reset corresponding ports, can obtain simultaneously the ILC message transmitting party from space switching chip veneer to time-division exchange chip veneer on this link to failure condition and carry out failure count.If (can be made as s*n*m second) space switching chip can not receive the reset request of opposite end time-division switching chip within a certain period of time, then with the failure count zero clearing, the expression fault is recovered.
With space switching chip veneer, data sync is the cycle with x second to the data sync that standby space switching chip veneer is responsible for regularly ILC being received and dispatched failure count to main.The record standby plate is to the ILC detection failure counting of each time-division switching chip single plate bidirectional on the standby space switching chip veneer.
Step 3, the master regularly detects the ILC failure count with space switching chip veneer, if surpass threshold values, then report and alarm; If the ILC fault recovery, then report and alarm recovers.
When detecting, main with space switching chip veneer (can be x*3 second) startup arbitration mechanism regularly, comprehensively judge primary, spare space switching chip, primary, spare time-division switching chip about ILC detection failure counting, whether decision switches the master is recovered the TDM channel failure with space switching chip or master with the time-division exchange chip.
Wherein, the arbitration principle comprises two aspect contents:
One, main arbitration principle of switching with the time-division exchange chip
1) main normal to standby time-division switching chip sending direction ILC detection with the space switching chip.Standby time-division switching chip sending direction can't be ILC and detect, and is not then considered;
2) master uses space switching chip sending direction ILC detection undesired with the time-division exchange chip to main; Perhaps the master uses time-division exchange chip sending direction ILC detection undesired with the space switching chip to main.
Under the situation that above two conditions all satisfy, can switch main with time-division exchange chip recovery.
Two, main arbitration principle of switching with the space switching chip
1) standby space switching chip detects normally with time-division exchange chip sending direction ILC to main;
2) main normal to standby space switching chip sending direction ILC detection with the time-division exchange chip;
3) the main time-division exchange chip of using uses space switching chip sending direction or the main space switching chip of using to use time-division exchange chip sending direction to the master to the master, and ILC detects abnormal situation.
Under the situation that above three conditions all satisfy, can switch main with the recovery of space switching chip.
Above-mentioned condition one, two all satisfies, and promptly switches mainly with the time-division exchange chip or switch and mainly can recover under the situation of fault with the space switching chip, is mainly and prevents space switching chip port reception fault, pays the utmost attention to switch the master and use the space switching chip.
Do not carry out the chip switching operation in other cases.
As can be seen from the above description, making full use of under the existing resources supplIes, by realizing testing mechanism to the ILC packet sending and receiving, in time and effectively TDM channel failure situation is judged and handled, and the form by fault warning, notify the attendant to handle, further reduced the probability that the TDM channel failure takes place.
Realize the highly redundant and the high availability of TDM interchange channel, when the master is broken down with the TDM passage, switched to standby available TDM passage.Through strict simulation test checking and actual sizable application, the ILC dynamic detection technology can be realized the timely recovery to the TDM channel failure, ensures TDM switching network safety to greatest extent and stable operation, promotes client's satisfaction effectively.
If unreal when reality ILC detects, also can realize the real-time detection of other modes in TDM service channel inside, but will reduce the professional effectively communication bandwidth of TDM, waste the in-band channel that the ILC control module of SBI interface is provided, also increase the complexity that software and hardware is realized simultaneously.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
