To interrupting detection module alarm after alarm detection module detecting alarm, interrupting producing after detection module receives this alarm interrupting, and the positional information of interruption and warning information are informed to interruption processing module with the form of interrupting information.
Interruption processing module, in order to obtain interrupting information from interruption detection module, and calculate according to the positional information in interrupting information and warning information the positional information occurring the wiring board port level (namely port level refers to which Port detecting is to multiplex section alarm) of alarm, and by message, this positional information and warning information are sent to upper strata multiplex section rearrangement decision-making module;
Switch decision-making module, message in order to send according to interruption processing module navigates to the multiplex section that will carry out switching action, and according to APS protocol byte information, warning information and local information, wherein, this local information comprises the decision-making switching actions such as local control command.
Time slot processing module, in order to calculate, switching is correlated with needs time slot to be processed, and according to the time slot position that the initial slot position calculation of the switching action and configuration of switching decision-making module goes out to switch, is handed down to bottom layer driving module;
Driver module, the time slot position information configuration in order to issue according to time slot processing module switch after time slot, complete the recovery of the business of switching;
Be described in detail the function of this embodiment below in conjunction with Fig. 2,3 and 4, this description, just in order to needs of illustrating, does not form the restriction to embodiment of the present invention protection range.
Step 301 to step 303 is multiplex section protection configuration process part, as shown in Figure 3, specific as follows:
Step 301, configuration multiplex section protection group A, and the multiplex section protection message of configuration multiplex section protection group A is issued to cross board, configure cross time-slot a->b simultaneously, and issue time slot message to cross board;
Supposing to configure the port one not being with extra 10G tetra-fibre to share ring protection group A, its wiring board I is working port, and it protects port-for-port 2, and the port 3 of another wiring board II is working port, and it protects port-for-port 4; Configure to enter from port one, the cross time-slot a->b that port 3 goes out simultaneously.Wherein, multiplex section protection message carries the related information of protection port and working port.Time slot message carries cross time-slot information.
Step 302, cross board resolves multiplex section protection message, records the relevant work of this multiplex section protection group and protection port numbers 1,2,3,4, is recorded by four ports.
Step 303, resolves time slot message, and record gap information, namely records cross time-slot a->b.
Step 304 to step 308 is multiplex section rearrangement processing section, as shown in Figure 4, specific as follows:
Step 304, the alarm detection module of wiring board I detects multiplex section warning information at port one, cross board is notified by core bus, make to interrupt detection module triggered interrupts, interrupting information comprises positional information and the warning information of the core bus of triggered interrupts, and interrupting information is notified interruption processing module;
Step 305, after interruption processing module receives interrupting information, calculate according to the positional information of interrupting and warning information and occur the positional information of the port one of the wiring board I of alarm, and the positional information and warning information that occur the port one of the wiring board I of alarm are sent to switch decision-making module;
Step 306, switch decision-making module get interruption processing module send information after, there is the multiplex section protection group A at the port one place of the wiring board I of alarm in location, and utilize APS (Automatic Protection Switching according to the warning information interrupted and local information, APS) protocol decisions goes out across the switching action of section bridge joint, then by switching action announcement slot processing module;
Step 307, time slot processing module obtains the port information 1 needing the multiplex section of switching action to configure, 2,3,4, from time slot object, obtain this according to port information and need time slot a->b to be processed, calculate time slot position a '->b after switching according to multiplex section rearrangement action, wherein, a ' is on the corresponding position of corresponding a of protection port 2; And the time slot position packing after switching is handed down to driver module.
Particularly, when multiplex section rearrangement occurs, initialization input time slot at i-th time slot position of working port, then protects input time slot position then at i-th time slot position of protection port; When there is bridge joint, initialization output time slot is at a kth time slot position of working port, then the output time slot position protected is then at a kth time slot position of protection port, and this calculating has explanation in G.841.Wherein, i, k are integer.
It should be noted that, in this example, the input time slot of cross time-slot is different, and output time slot is identical, but in practical application, the input time slot of cross time-slot and output time slot also can be different.
Step 308, driver module, according to the gap information configuring chip of packing, completes the recovery of the business of switching.
