Description

Single board operation method and system in active/standby mode

technical field

The invention relates to the field of communication technology, in particular to a method and system for operating a single board in an active/standby mode.

Background technique

In the telecommunications system, in order to improve the reliability of the system, a redundant backup board is usually added to the main board to ensure that when a single board fails, the redundant backup board can continue to execute the current business in time and reduce the impact on users .

The redundancy mode adopted for single boards in the prior art generally includes an N+1 resource pool working mode or a 1+1 active/standby mode.

Wherein, the working mode of the N+1 resource pool means that N boards work and one board performs backup. When any one of the N boards fails, the backup board takes over the work of the board. However, in this working mode, multiple veneers back up to one veneer, and in the case of the same memory, the backup veneer cannot fully back up all call data. Only important data can be selected, such as base station, cell and other information, so when a board fails, most users will drop calls.

For the 1+1 active/standby mode, that is, each board is equipped with a single board as a backup, the main board works, and the backup board only serves as the backup of the main board. When the main board fails, the standby board is promoted to the main board through switching, and the IP address is switched to the IP address of the main board to take over the work of the original main board. Although this mode can well guarantee that the original users will not drop calls and has high reliability, but when the main board does not fail, the backup board is always in an idle state, which is equivalent to only one of the two boards. Board thing, this mode has high hardware redundancy and poor performance.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Referring to FIG. 1 , it is a flowchart of a method for operating a single board in active/standby mode according to an embodiment of the present invention.

The method can include:

Step 101, divide the resources into at least two resource blocks that can operate independently, and allocate the resource blocks to the primary board and its standby board.

In the prior art, resources on a single board are not divided, but run on either the main board or the standby board. In the embodiment of the present invention, resources are first divided, and the division standard is Each divided resource block can run independently, and there is no need to refer to other resource blocks when running a certain resource block.

The resource division process can be divided by a third party other than the primary board and the standby board, or can be divided by one of them.

After the division is completed, a third party or one of the two will allocate resource blocks. Specifically, at least two divided resource blocks can be allocated to the main board and the standby board respectively. different resource blocks, the amount of resources can be equal or unequal; it is also possible to allocate all resource blocks on the main board and the standby board, for example, backup all resource blocks according to the number of boards, and then allocate , so that all resource blocks are stored on each single board.

The step of dividing resource blocks can be performed in advance, and it is not necessary to perform division once every time a single board runs.

Step 102 , the primary board runs the first resource block to communicate with the external board, and the standby board runs the second resource block to communicate with the external board.

After the resource blocks are allocated to the main board and the standby board, the main board runs part of the resource blocks, which is recorded as the first resource block, and the standby board runs another part of the resource blocks, which is recorded as the second resource block. The first resource block is different from the second resource block.

When the active and standby boards are running their respective resource blocks, they can communicate with the external boards separately, or a common communication module can communicate with the external boards, for example, the standby board communicates through the agent on the main board. The module communicates with an external single board, etc., and the specific communication method is not limited here.

Step 103, when the standby board detects that the primary board fails, the standby board runs the second resource block and the backup of the first resource block stored on the standby board, and communicates with the external board.

The standby board can detect the running status of the main board through the software handshake signal between the main board and the standby board. The business on the primary board is to run the backup of the first resource block on the standby board, and to communicate with other external boards.

Wherein, the backup of the first resource block may be pre-stored on the standby board when the resource block is allocated, or may be temporarily backed up by the master board to the backup board when a fault occurs or before a fault occurs.

In another embodiment, when the faulty single board is restored to use, it can be switched back to the method of step 102, that is, when the main single board is restored, the main single board still runs the first resource block to communicate with the external single board, and the The standby board runs the second resource block and communicates with the external board.

In this embodiment of the present invention, the main board and the standby board are relative terms, and do not specifically refer to a certain board. The same can be realized, and it is within the protection scope of the present invention. "First" and "second" are only used to distinguish different resource blocks, and are not specific.

In the embodiment of the present invention, resources are divided and run on the active and standby boards respectively, so that the active and standby boards can participate in the operation resources and communicate with external boards at the same time. In the case of running and the standby board is idle, the CPUs of the main and standby boards participate in the operation at the same time in the method of this embodiment, which greatly reduces the redundancy of the hardware, makes full use of the hardware resources, and improves the hardware performance. The processing capacity under this mode It is twice the processing capacity of the prior art method. Moreover, when a single board fails, another single board takes over the resources on the faulty single board to avoid service communication interruption and ensure high reliability of the system.

Referring to FIG. 2 , it is a flow chart of another method for operating a single board in active/standby mode according to an embodiment of the present invention.

The method can include:

Step 201, divide the resource M into two resource blocks M1 and M2 that can operate independently, and allocate the resource blocks to the master board and its backup board.

In this embodiment, the resource M is divided into two independently operable resource blocks, the first resource block M1 and the second resource block M2 as an example for illustration.

The specific resource division method is to extract the global variables in each resource block and store them in a unified structure, called the environment control block. Each single board uses a corresponding independent resource block through a different environment control block pointer.

After the division is completed, the first resource block M1 and the second resource block M2 are backed up, the backup M2' of the first resource block M1 and the second resource block M2 is allocated to the main board, and the backup of the first resource block M1 M1' and the second resource block M2 are allocated to the standby boards. Although the resource blocks stored in the active and standby boards are the same, the resource blocks operated by each board are different, as in step 202 below.

Step 202, the main board runs the first resource block M1 to communicate with the external board, and the standby board runs the second resource block M2, and communicates with the external board through the proxy communication module on the main board.

After the resource blocks are allocated to the master board and the backup board, the master board runs the first resource block M1, and the backup board runs the second resource block M2, and the two resource blocks are different.

In this embodiment, the main board communicates with the external board through its own communication module using its own IP address IP1, and the standby board uses the IP address IP1 of the main board through the proxy communication module on the main board. The address IP1 communicates with the external board, as shown in Figure 3, the communication mode of the master board does not require other boards to perceive, and the impact is relatively small.

Based on this proxy communication mode, due to the relatively large overhead on the master board, the amount of resource blocks running on the standby board and the master board may be different. For example, the resource amount of the second resource block M2 running on the slave board is greater than that of the master board. The resource amount of the first resource block M1 running on the single board, for example, M2:M1 is 6:4, and so on.

Step 203, when the backup board detects that the master board is faulty, the backup board runs the second resource block M2 and the backup M1' of the first resource block, uses the IP address IP1 of the master board, and communicates with the external board to communicate.

The standby board detects the running status of the main board through the software handshake signal between the main board and the standby board. When it learns that the main board is faulty, the standby board takes over The backup M1' of the first resource block stored on the board communicates with the external board. In this case, the standby board can run the backup M1' of the first resource block and the second resource block M2 at the same time, and switch the IP address IP1 of the main board to its own IP address, that is, use the IP address of the main board IP1, communicate with external single boards, and send ARP (Address Resolution Protocol, Address Resolution Protocol) messages to other external single boards, and update ARP entries of other external single boards.

Since the standby board runs the backup M1' of the first resource block and the second resource block M2 at the same time, the business may exceed the CPU load of the standby board. At this time, flow control can be started. The flow control can include sharing calls to other boards, or Refusal of certain services, etc.

Step 204, when the backup board detects that the main board is restored, the backup board runs the second resource block M2 to communicate with the external board, and communicates with the external board through the proxy communication module on the main board; wherein, The main board resumes running and the first resource block M1 communicates with the external board.

When the standby board detects that the master board has recovered, it can switch the running state of the master board back to the state corresponding to step 202, that is, the slave board runs the second resource block M2, through the agent communication module on the master board Communicate with the external board, and the main board resumes running. The first resource block M1 communicates with the external board.

In another embodiment, if the fault occurs in step 203 is the standby board, the master board directly runs the first resource block M1 and the backup M2' of the second resource block, using the IP address of the master board IP1 communicates with the external board, and switches back to the state of step 202 after the backup board recovers.

In the embodiment of the present invention, resources are divided and run on the active and standby boards respectively, so that the active and standby boards simultaneously participate in the communication between running resources and external boards, greatly reducing the redundancy of hardware and making full use of hardware resources, which improves the hardware performance, and when a single board fails, another single board takes over the resources on the faulty single board, avoiding the interruption of business communication and ensuring the high reliability of the system.

Referring to FIG. 4 , it is a flow chart of another method for operating a single board in active/standby mode according to an embodiment of the present invention.

The method can include:

Step 401, divide the resource M into two resource blocks M1 and M2 that can operate independently, and allocate the resource blocks to the master board and the backup board.

In this embodiment, the first resource block M1 and the second resource block M2 divided by the resource M are still taken as an example for illustration. The resource division process and resource block allocation process are similar to the aforementioned step 201, and will not be repeated here.

Step 402, the main board runs the first resource block M1, and communicates with the external board through the IP address IP1 of the main board; the backup board runs the second resource block M2, and communicates with the external board through the IP address IP2 of the backup board The board communicates.

After the resource blocks are allocated to the master board and the backup board, the master board runs the first resource block M1, and the backup board runs the second resource block M2, and the two resource blocks are different.

In this embodiment, the main board communicates with external boards through its own communication module using its own IP address IP1, and the standby board uses its own IP address IP2 and The external single board communicates, as shown in Figure 5.

Based on the autonomous communication mode, the resource amounts of the resource blocks running on the primary board and the standby board may be the same, for example, M1:M2 is 1:1.

Step 403, when the standby board detects that the main board fails, the backup board adds the IP address IP1 of the main board, and sends an ARP message to the external board.

The standby board detects the running status of the main board through the software handshake signal between the main board and the standby board. , because the standby board and the main board communicate with external boards through their own IP addresses, the backup board needs to take over the services on the main board and the IP address IP1 of the main board.

The standby board needs to first increase the IP address IP1 of the main board locally, and send an ARP message to other external boards to update the ARP entries of other external boards, that is, the IP address of the main board corresponding to the address IP1 in the ARP entry. The MAC address is updated to the MAC address of the standby board, so that the standby board can take over the services of the main board and communicate with external boards.

Step 404, the standby board runs the second resource block M2, uses the IP address IP2 of the standby board, and communicates with the external board, and the backup board runs the backup M1' of the first resource block, using the IP address of the main board IP1, communicate with the external board.

After the standby board adds the IP address IP1 of the main board to the local area, the standby board still runs the second resource block M2 and uses the original IP address IP2 of the standby board to communicate with external boards. The standby board runs the backup M1' of the first resource block stored on the standby board, and uses the IP address IP1 of the main board to communicate with the external board.

Since the standby board runs the second resource block M2 and the backup M1' of the first resource block at the same time, the business may exceed the CPU load of the standby board. At this time, flow control can be started. The flow control can include sharing calls to other boards, or Refusal of certain services, etc.

Step 405, when the standby board detects that the main board is recovered, the standby board runs the second resource block M2, and uses the IP address IP2 of the standby board to communicate with the external board.

When the standby board detects that the main board is recovered, the running state of the standby board is switched to the state of step 402, that is, it runs the second resource block M2 and uses the IP address IP2 of the standby board to communicate with the external board. For the services of the main board replaced by the standby board, switch back to the main board and be executed by the main board.

Wherein, the switching process of the main board may be:

After the recovery of the main board, if it is detected that the IP address IP1 of the main board is used (this address IP1 has been added to the standby board in step 403), it will first start with the standby IP address IP3, and the first When the resource block is M1, switch the standby IP address IP3 to the IP address IP1 of the main board, and send an ARP message to the external board, so that the ARP entry of the external board returns to the state before the failure of the main board. The board runs the first resource block M1, and uses the IP address IP1 to communicate with the external single board.

In another embodiment, if the fault occurs in step 403 is the standby board, the main board will directly perform steps similar to steps 404-405. The switching process switches back to the state of step 402 .

In the embodiment of the present invention, resources are divided and run on the active and standby boards respectively, so that the active and standby boards simultaneously participate in the communication between running resources and external boards, greatly reducing the redundancy of hardware and making full use of hardware resources, which improves the hardware performance, and when a single board fails, another single board takes over the resources on the faulty single board, avoiding the interruption of business communication and ensuring the high reliability of the system.
