Embodiment
Core concept of the present invention is by a scan counter, successively to 64 STM-1 (STM, synchronous transfer mode) effective marker scans, and according to described effective marker corresponding passage is carried out data parameters and handle, that is to say if this sign is set (being that described effective marker is for carrying out the effective marker that data parameters is handled to this passage), then this passage being initiated a data parameters handles, otherwise, this passage not being carried out data parameters handles, and only the scan counter count value is added 1, enter the data parameters processing procedure of next passage.
Each passage all relates to a large amount of alarms, returns and accuse and performance counter count value (being performance error code aggregate-value), if each channel parallel data parameters is handled, owing to for pairing various alarms of each passage and time announcement a specific state transition algorithm or formula are arranged all, therefore need a large amount of state exchange logic and register; Each passage also needs two performance counters to carry out the statistics of performance error code aggregate-value simultaneously, therefore also needs a large amount of registers and adder; Like this, if to each channel allocation one block RAM (random asccess memory) though can alleviate the nervous problem of resource that register causes, the number of RAM is too much, bring problem can for the chip back end design; Therefore, method of the present invention is they all to be stored in the block RAM go, and the institutional framework of RAM is a horizontal organization structure, and each row of the RAM of horizontal organization structure is deposited the data parameters of a passage, and described data parameters comprises the state value and the performance counter count value of all state machines.
The invention provides the method that realizes the tandem connection monitor terminal processes in a kind of network service, the embodiment of described method is as follows:
Step 1: whether each passage is set needs to carry out the effective marker that data parameters is handled, be whether each passage setting needs to carry out processing of performance error code accumulative total and/or alarm and return the effective marker that announcement is handled, carry out the processing of corresponding data parameters if desired, then, be set to carry out the effective marker that data parameters is handled with effective marker set; If do not need to carry out the processing of corresponding data parameters,, be set to not need to carry out the effective marker that data parameters is handled then not with effective marker set.
Step 2: scan each passage successively, and according to the effective marker of each passage it is carried out corresponding data parameters and handle, the data parameters of each passage is handled the following method that all adopts: earlier from RAM reading and saving before the result that handles of data parameters, pass through the corresponding data parameters treatment circuit of each state machine self then, state value of respectively being made a fresh start or count value, they are written back in the middle of the RAM at last, have so just realized that 64 passages time division multiplexing corresponding state processing circuit and performance counter treatment circuit under the control of scan counter carry out the processing of corresponding state value and count value;
This process of described step 2 further comprises:
Step 21: scan counter is set, and scan counter is writing down and need carry out the channel number that data parameters is handled;
Step 22: according to the count value scanning respective channel of scan counter, obtain the effective marker of respective channel, so that judge whether that according to effective marker needs carry out data parameters to this passage and handle;
Step 23: judge whether described effective marker is to carry out the effective marker that data parameters is handled, if, execution in step 24, otherwise, execution in step 25;
Step 24: definite passage that need carry out the data parameters processing is carried out processing of performance error code accumulative total and/or alarm and time announcement simultaneously handle, after finishing dealing with, scan counter need be added 1, go to execution in step 22, next passage is handled accordingly;
The performance error code of described passage accumulative total is handled and/or alarm and return to accuse to handle and comprise: to the state value of each state machine of multi-frame handle with obtain new state value, to the processing of the state value of each state machine of non-multi-frame with obtain new state value and to the processing of performance counter count value to obtain new count value;
Step 25: do not carry out the processing of data parameters, directly scan counter is added 1, and execution in step 22, next passage is handled accordingly.
Step 3: after carrying out described step 2, also need to preserve corresponding result usually;
The result that is about to step 2 is stored among the RAM, and described RAM adopts horizontal organization structure, and the result of a passage all is stored in the horizontal delegation of RAM, and concrete institutional framework is as shown in the table:
| The address | Channel number | Multi-frame | Non-multi-frame | |||||||||
