Fig. 3 is a flowchart of an inter-board data adding method according to an embodiment of the present disclosure, where the inter-board data adding method is applied to an LPU, and the LPU is pluggable into a trunking line card slot, and the trunking line card slot is disposed in an FCC. The inter-board data adding method provided by the embodiment of the application can be suitable for a router cluster system or a single-machine non-cluster system. As shown in fig. 3, the method of the present embodiment includes:
s310, after the first resource data are added to each other by two of the plurality of switching chips in the first service line card board LPU1, configuring a priority for adding the second resource data of the switching chip in the second service line card board LPU 2.
Specifically, in one example, two switch chips (switch chip 1 and switch chip 2) are included in LPU1, and first resource data of the switch chip of each other is added between switch chip 1 and switch chip 2. That is, the exchange chip 1 adds the first resource data of the exchange chip 2, and the exchange chip 2 adds the first resource data of the exchange chip 1; the first resource data specifically refers to resource data such as queue mapping, flow control mapping, BUFF resource allocation, scheduling mapping allocation and the like.
After the switching chips in the LPU1 add the first resource data to each other, the LPU1 configures the order priority of adding the second resource data of the switching chips in the LPU 2.
The LPUs 1 and 2 described in this embodiment can be understood as follows: for a router cluster system, "LPU 1" is any LPU in the cluster, and the corresponding "LPU 2" is all LPUs except LPU1 in the cluster, and in this case, if it is assumed that LPU1 belongs to LCC1, LPU2 includes both LPUs belonging to LCC1 and LPUs belonging to LCCs except LCC1 in the cluster; for the case of a stand-alone non-cluster, "LPU 1" is any LPU on the LCC, and the corresponding "LPU 2" is all LPUs on the LCC except LPU1, where both LPU1 and LPU2 belong to the same LCC.
And S320, creating a data adding task corresponding to the LCC where the LPU2 is located on the LPU1, wherein the data adding task is used for adding second resource data of all switching chips in the LPU2 in the LCC into the LPU 1.
Specifically, data addition tasks equal to the number of LCCs in which LPU2 resides are created on LPU 1. In one example, if N LCCs are included in the cluster system, N data add tasks are created on LPU1, where each data add task corresponds to one LCC and the N data add tasks may run in parallel.
S330, executing the data adding task based on the sequence priority.
Specifically, the LPU1 adds the second resource data of the switching chip within the LPU2 to the LPU1 according to the order priority configured at step S320.
In this embodiment, after resource data are added to each other by an exchange chip in a certain LPU, by configuring a sequence priority for adding resource data of exchange chips in other LPUs and creating data addition tasks corresponding to the number of LCCs, the LPU can execute the data addition tasks based on the sequence priority, thereby realizing sequential addition of resource data between frames and exchange chips in the frames; the embodiment can remarkably reduce the task amount required to be created, does not need to perform inter-frame communication when executing the data adding task, and can realize the rapid adding of the data between the boards.
It should be noted that the inter-board data adding method of the present application may be applied to LPUs in a cluster system, and may also be applied to LPUs in a stand-alone non-cluster environment, for convenience of description, the following embodiments of the present application are described by taking LPUs applied in a cluster system as an example, and when the inter-board data adding method of the present application is applied to LPUs in a cluster system, the LPU2 described in the present application includes both an LPU belonging to LCC1 and an LPU belonging to other LCCs except LCC1 in the cluster.
In the prior art, since the resource data can be added or deleted between the switching chips only by responding to the insertion or extraction operation of the LPUs, when the LPUs are repeatedly inserted and extracted, the data needs to be repeatedly added or deleted by the LPUs in place, that is, when the LPUs in a certain slot are extracted, the resource data of the switching chip corresponding to the extracted LPUs can be deleted by the LPUs in place, and after the LPUs are reinserted into the slot, the resource data of the switching chip needs to be newly added by the LPUs in place, so that the resource data of the switching chip in the same slot can be repeatedly added or deleted, and system resources are occupied.
The application enables the LPU1 to add the resource data of the plurality of switching chips in the LPU2 to the LPU1 without depending on the insertion or extraction operation of the LPU by configuring the order priority for adding the second resource data of the switching chips in the second service line card board.
In an embodiment of the present application, after adding the first resource data to each other by two of the plurality of switching chips in the first service line card board, before configuring the priority of the order for adding the second resource data of the switching chip in the second service line card board, the method in fig. 3 further includes:
and receiving service line card board state information, wherein the service line card board state information comprises first identification information of a trunking line card frame where the LPU2 is located, in-place state information of the LPU2 and second identification information of the LPU 2.
Specifically, when the method of this embodiment is applied to a cluster system, a main control chip in any FCC may be selected as a main control of the cluster system, where the main control is used to detect the states of all frames, slots, and cards in the cluster system, and obtain the state information of all frames, slots, and cards; at this time, the main control chip in the FCC sends the service line card board state information to the main control chip in each LCC, and the main control chip in each LCC sends the service line card board state information to the LPU on the LCC.
When the method of the embodiment is applied to a stand-alone non-cluster, a main control chip in the LCC is used as a main control, and the main control is used for detecting the states of all frames, slots and clamping plates in the stand-alone to acquire the state information of all the frames, the slots and the clamping plates; at this time, the main control chip in the LCC sends the status information of the service line card board to the LPU thereon.
After the state information of the service line card board is obtained, the order priority for adding the second resource data of each switching chip in the LPU2 can be configured according to the first identification information, the in-place state information and the second identification information.
Illustratively, the order priority for adding the resource data of each switching chip in the second service line card board is configured by:
judging whether the first identification information is a preset identification or not according to the first identification information, wherein the preset identification can be represented by a normal identification;
if the first identification information is a preset identification, configuring an LCC (the LCC is the LCC of which the first identification information is the preset identification) as a first frame priority, and judging whether LPU2 exists in cluster line card slots (the cluster line card slots are all card slots arranged in the LCC with the first frame priority) and whether second identification information is the preset identification according to the in-place state information and the second identification information;
if the LPU2 exists in the cluster line card slot and the second identification information is a preset identification, configuring the cluster line card slot as a first slot priority;
if the LPU2 exists in the trunking line card slot and the second identification information is not a preset identification, configuring the trunking line card slot as a second slot priority;
if the LPU2 does not exist in the cluster line card slot, configuring the cluster line card slot as a third slot priority;
if the first identification information is not the preset identification, configuring the LCC (the LCC is the LCC of which the first identification is not the preset identification) as the second frame priority, and configuring the cluster line card slot (the cluster line card slot is all card slots set in the LCC with the second frame priority) as the third slot priority.
The frame priority is a first frame priority and a second frame priority from high to low, and the slot priority is a first slot priority, a second slot priority and a third slot priority from high to low.
The LPU1 of the present embodiment configures an order priority indicating an addition order of the second resource data of the switch chip within the LPU2 according to the service line card board state information by acquiring the service line card board state information, so that the LPU1 completes the addition of the second resource data at once using the order priority without depending on the insertion or extraction operation of the LPU.
In practical application, in this embodiment, before adding the first resource data to each other by two of the plurality of switch chips in the LPU1, for example, when the LPU1 is started, an association relationship between the second resource data and the cluster line card slot into which the LPU2 is inserted is established, where the association relationship is used to obtain the second resource data corresponding to the cluster line card slot into which the second service line card board is inserted when the data addition task is executed.
Accordingly, based on the foregoing order priority, and according to the association relationship, the data addition task may be executed:
when the frame priority of the LCC in which the LPU2 is located is the first frame priority, sequentially adding the second resource data of the plurality of switch chips in the LPU2 in the cluster line card slot according to the slot priority order and the association relationship of all the cluster line card slots on the LCC with the first frame priority;
when the frame priority of the LCC in which the LPU2 is located is the second frame priority, second resource data of the plurality of switch chips in the LPU2 in the cluster line card slot are sequentially added according to the slot priority order and the association relationship of all the cluster line card slots on the LCC having the second frame priority.
Specifically, when the frame priorities of the LCCs where the LPU2 are located are all the first frame priorities, second resource data of a plurality of switching chips in the LPU2 corresponding to the trunking line card slots of which the slot priorities on the LCCs are the first slot priorities and the second slot priorities are sequentially obtained according to the association relationship, and the obtained second resource data are added into the LPU 1;
when the frame priorities of the LCC where the LPU2 are located are all the second frame priorities, sequentially acquiring second resource data of a plurality of switching chips in the LPU2 corresponding to all cluster line card slots on the LCC according to the association relationship, and adding the acquired second resource data into the LPU 1;
when the frame priority of the LCC in which the LPU2 is located includes both the first frame priority and the second frame priority, first obtaining second resource data of a plurality of switch chips in the LPU2 corresponding to the cluster line card slot having the LCC of the first frame priority and the slot priority of the first slot priority and the slot priority of the second slot priority according to the association relationship, and adding the obtained second resource data to the LPU 1; after the second resource data are completely added, the second resource data of the plurality of switching chips in the LPU2 corresponding to the cluster line card slot with the LCC of the first frame priority and the third slot priority are obtained according to the association relationship, the second resource data are added to the LPU1, the second resource data of the plurality of switching chips in the LPU2 corresponding to all the cluster line card slots on the LCC of the second frame priority are obtained according to the association relationship, and the second resource data are added to the LPU 1.
According to the embodiment, the second resource data of the corresponding switching chip in the LPU2 is sequentially added according to the association relationship between the second resource data and the cluster line card slot and the frame priority and the slot priority, so that the second resource data of the switching chip in the LPU2 corresponding to the cluster line card slot with the higher slot priority can be preferentially added, and the rapid message interaction between the LPUs with the high priority is facilitated.
In practical application, after creating the data adding task, the inter-board data mutual adding method of this embodiment may further include:
and creating a data addition monitoring task, wherein the data addition monitoring task is used for detecting and confirming the resource data of each exchange chip in the second service line clamping plate added by the first service line clamping plate.
To specifically describe the detailed process of adding data between boards in the embodiment of the present application, the following description is made with reference to fig. 4 and 5.
In this embodiment, each LCC in the cluster system is provided with the first identification information, and each LPU is provided with the second identification information, and this embodiment exemplarily illustrates that the LPU1 in the cluster system performs inter-board data addition, and at this time, all other LPUs in the cluster system are represented by LPU 2.
When the mutual addition of the first resource data among the plurality of switching chips in the LPU1 is completed, the master control of the cluster system can acquire the identifier of each LCC, the identifier of each LPU, and the in-place state information of each LPU in the cluster system, form the state information of the service line card board, and issue the state information; the LPU1 receives the status information of the service line card board, and configures a priority for adding the second resource data of each switch chip in the second service line card board based on the status information of the service line card board.
In the cluster system, any LPU in the cluster system configures the order priority in steps S411 to S419, and in the case where the stand-alone is not a cluster, any LPU in the LCC configures the order priority in steps S414 to S419. The order priority of the present embodiment includes a slot priority and a frame priority.
S411, training the first identifiers of all LCCs in turn, and executing step S412.
The LPU1 trains the first identifiers of all LCCs in turn after receiving the service line card status information sent by the FCC.
S412, determine whether the first flag of each LCC is a default flag Normal, if so, execute step S414, otherwise, execute step S413.
S413, configure the frame priority of the LCC as a second frame priority, and configure the slot priorities of all the trunking group card slots on the LCC as third slot priorities.
S414, configuring the frame priority of the LCC as the first frame priority, training all the trunking card slots on the LCC in turn, and executing step S415.

S417, determine whether the second identifier of the hub group card slot of the LPU in place is the default identifier Normal, if so, execute step S419, otherwise execute step S418, and configure the slot priority of the hub group card slot as the second slot priority.
S419 configures the slot priority of the trunking group card slot to be the first slot priority.
After the order priorities are configured, data addition tasks equal to the number of LCCs in which the LPU2 is located are created on the LPU1, so that one data addition task corresponds to one LCC, and when the LPU1 executes one data addition task, the second resource data of the plurality of switch chips in all the LPUs 2 on the corresponding LCC can be added to the LPU 1.
For convenience of explaining a process of adding data between boards by LPUs, in this embodiment, it is assumed that a cluster system includes three LCCs, i.e., LCC1, LCC2, and LCC3, and frame priorities of LCC1, LCC2, and LCC3 are respectively a first frame priority, and a second frame priority, and since execution logic of adding data between boards by each LPU in the cluster system is the same, this embodiment takes one of the LPUs, i.e., LPU1, as an example to perform a data addition task.
Based on the above assumption of the present embodiment, three data adding tasks task1, task2 and task3 are created on the LPU1, and task1, task2 and task3 respectively correspond to LCC1, LCC2 and LCC3, where fig. 5 shows an execution process of the data adding task, and the specific process is as follows:
s511, the LPU1 determines whether the data add task requires high priority processing, if not, executes step S512, and if so, executes step S513.
Based on the above assumption of the present embodiment, the data adding tasks task1, task2, and task3 correspond to LCC1, LCC2, and LCC3, respectively, and since the frame priorities of LCC1 and LCC2 are both the first frame priority and the frame priority of LCC3 is the second frame priority, the LPU1 determines that the data adding tasks task1 and task2 execute step S513; and the judgment data adding task3 executes step S512.
Since the LPU1 performs the logic of the data adding task1 and the data adding task2, for convenience of description, the process of adding inter-board data by the LPU1 is explained with the LPU1 performing the data adding task1 and the data adding task 3.

In the process of executing the data adding task1, after adding the resource data of the multiple switch chips in the LPUs corresponding to all the cluster line card slots with the first slot priority on the LCC1 according to the association relationship, the LPU1 continues to train all the cluster line card slots on the LCC1 in turn, adds the second resource data of the multiple switch chips in the LPUs corresponding to all the cluster line card slots with the slot priority as the second slot priority according to the association relationship, marks the added LPU, and after the addition of the second resource data is completed, the LPU1 executes step S515.
S515, the LPU1 determines whether the second resource data of the switching chips in the LPUs in the trunking line card slot with the second slot priority has been completely added, if so, executes step S516, otherwise, waits for the LPU1 to completely add the second resource data of the switching chips in the LPUs corresponding to the trunking line card slot with the second frame priority.
During execution of the data adding task1, after the LPU1 has completed adding the second resource data of the plurality of switch chips in the LPU corresponding to the cluster line card slot with the second slot priority on the LCC1 and has determined that the data adding task2 has completed adding the second resource data of the plurality of switch chips in the LPU corresponding to the cluster line card slot with the second slot priority on the LCC2, the LPU1 executes step S516.
