Description

Active and standby competition method, device and application device Technical field

The present application relates to the field of communications technologies, and in particular, to an active/standby competition method, apparatus, and application device.

Background technique

In the existing communication equipment, especially the frame type communication equipment, in order to stably operate the system, it is often necessary to have two main control boards to undertake equipment management work, and one main control board bears the main main control role of the equipment. The other main control board assumes the standby main control role of the device. When the main control board fails and cannot assume the main role of the main control, the standby main control board takes over the role of the main control board to ensure the role. The normal operation of the device ensures the normal operation of the communication device service processing, thereby reducing the impact of device failure on the user service. Taking a frame type communication device as an example, referring to FIG. 1, the communication device 1.1 has two main control boards 1.2, 1.3, two switch boards 1.4, 1.5, and N service boards 1.6, 1.7, . .., 1.n. In the communication device 1.1, through the inter-board channel, such as the midplane or the connector or the backplane, the two main control boards 1.2, 1.3 and the two switch boards 1.4, 1.5 and N service boards 1.6, 1.7 ,..., 1.n connection. The two main control boards 1.2 and 1.3 are determined by the active/standby competition mechanism in the communication device 1.1, and the respective board roles are determined as the main control board and the standby main control board, and the selected main control is selected. The board realizes the overall management control of the entire chassis-type communication device 1.1.

In the prior art, with reference to FIG. 1 and FIG. 2, the basic process of the active/standby competition mechanism applied to the common chassis-type communication device 1.1 includes the active-standby competition process in the system startup phase, and the specific steps include

Step 201, establishing communication connections between the two main control boards 1.2 and 1.3;

Step 202: The two main control boards 1.2 and 1.3 respectively send an active/standby competition message carrying the information of the own board to the other party;

Step 203: The two main control boards 1.2 and 1.3 respectively receive the contention message of the other party;

Step 204: After receiving the contention message of the other party, the two main control boards 1.2 and 1.3 initially determine the role of the board as the main control board or the standby main control board according to the active/standby competition message of the other party;

Step 205: The two main control boards 1.2 and 1.3 respectively send a response message carrying the role of the own board to the other party;

Step 206: The two main control boards 1.2 and 1.3 respectively receive the response message of the other party;

Step 207: The two main control boards 1.2 and 1.3 respectively determine whether the other party's board role conflicts with its own board role. If there is a conflict, the content is re-competitive. If there is no conflict, the active/standby competition is completed, and finally the selected one is selected. The main control board 1.2 or 1.3 that assumes the main control role realizes the management control of the other boards 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, ..., 1.n in the chassis type communication device 1.1, The other main control board 1.3 or 1.2 assumes the role of the standby master of device 1.1.

After analyzing the existing technology, referring to Figures 1 and 2, it is not difficult to find that the existing chassis-type device 1.1 adopts a dual-master scheme, and the operation of the active-standby competition mechanism completely depends on the main control board 1.2, 1.3, if two masters If the boards 1.2 and 1.3 are faulty or unplugged, the entire chassis-type device 1.1 cannot be operated without the main control state, and the system reliability is reduced. Moreover, if the number of slots of the chassis-type device 1.1 is small, for example, there are only six slots, the design of the active-standby competition mechanism that relies on the dual-master board in the chassis-type device 1.1 may be excessive. The slot of the chassis is occupied, which limits the number of other cards and cannot meet more business requirements.

In addition, the active/standby competition mechanism relies on two main control boards 1.2 and 1.3 to establish communication connections and exchange competing messages. If the main control board 1.2, 1.3 is plugged or unplugged, or due to hardware differences, etc. If the startup interval of the control board 1.2 and 1.3 is too large, the time for establishing the communication connection between the two main control boards 1.2 and 1.3 will become very long. At this time, the operation of the entire active/standby competition mechanism will slow down the system. Start Time.

Detailed ways

The specific embodiments of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

FIG. 3 is a flowchart of a method for competing for the active and standby of the present application. As shown in FIG. 3, the active/standby competition method includes:

Step 301: Determine a priority rule according to the slot information of the card, the function type of the card, the slot information of other online boards, and the type of functions of other online boards, and determine the board according to the priority rule. The delay time of the detection is started, wherein the board and other online boards are plugged into corresponding slots of a middle board, and each board is communicatively connected, and the board and other online boards have Control function, the function type includes a main control board, a switch board, and a service board.

Each of the boards includes a main control board, a switch board, a service board, and the like. The boards of the main control board, the switch board, and the service board are plugged together through a middle board, that is, Each board is inserted into a slot of the middle board; and a communication connection is established between the boards, and a plurality of communication connections can be established between the boards. In this embodiment, a switch can be set. The switching device SW is implemented to implement a communication connection between any two boards.

The switch switching device SW is composed of a smart ASIC chip having a control function and a switching function, the chip has a plurality of interfaces, and each of the plurality of interfaces can be configured as a path with any other interface, using a switch switching device The SW can establish an inter-board information channel between each board, realize the communication connection of each board, and realize the two-two interconnection between the boards. It should be noted that the inter-board information channel between the boards established by the device SW may be an information channel based on Ethernet.

In addition, the inter-board information channel between the boards may also be constituted by a dedicated signal line connected through the middle board.

The method for determining the delay time includes:

a. Determine the serial number of the card slot of each board and the functions implemented by each board;

Each board can obtain information about the slot of the board and a slot information of the other board through the board. The slot information of the board is the information provided by the board to each board. The information reflects In the present embodiment, the slot information of the board provided by the middle board is represented by a set of high and low level signals. For example, 001 indicates that the slot of the board is 2 slots, and 011 indicates this. The slot of the board is 4 slots. The slot information of the other online boards is orthogonally plugged into the middle board by the boards, causing a group of high and low level signal changes on the middle board. Whether the bit has the card insertion and the slot information of each card, the board obtains the level signal to determine the slot information of other online boards. For example, 001 indicates that the slot is inserted in slot 2, and 011 indicates that the slot is inserted in slot 4. The determining the functions implemented by each card may be, for example, determining whether the boards belong to a main control board or a switch board, or other service boards, and the like.

b. determining the priority order of the boards according to the descending or ascending order of the slot numbers of the boards, and the types of functions implemented by the boards;

In this step, the priority of each board may be determined according to the descending or ascending order of the slot numbers of the boards, and the functions implemented by each board. For example, the principle of descending order of the slot number, that is, the smaller the slot number, the higher the priority of the board, and the priority of the main control board is greater than the switch board, and the priority of the switch board is greater than the rules of the service board. The priority order of the cards. It should be noted that, the present application comprehensively considers the slot number of each board and the function of each board to determine the priority. The specific corresponding rules may be specifically determined according to the actual situation, and are not limited to the present application. For example, the priority of the main control board is greater than that of the switch board, and the priority of the switch board is greater than that of the service board. Each board is pre-scheduled according to the function, and then the external priority order is set, and then the board with the same function is used. The card, for example, multiple service boards, is further arranged in descending order or ascending order of the slot number to determine an internal priority order, and finally according to the external priority order and internal priority The order of the levels determines the final order of priority. The above-mentioned corresponding rules for determining the priority based on the slot number of each board and the function of each board card may be determined according to specific conditions, and the priority level corresponding to each board function may also be changed according to actual conditions, for example, when When the main control board needs to be used for deep packet parsing, the priority rule can be changed to the priority of the switch board greater than the main control board.

c. Determine the delay time for the board to initiate detection according to the rule that the higher the priority is, the shorter the delay time is.

After the priority of each board is determined as described above, the delay time of the respective boards is determined according to the rule that the higher the priority is, the shorter the delay time is, so that the board with higher priority has greater initiative and The possibility to assume the role of the main master service. The specific implementation manner may be that the priority level priority is set to 0 level, 1 level, 2 level, ..., etc. in order from highest to lowest, and level 0 represents the highest priority level, by timeout=priority* 1000ms to calculate the delay time of each board. Certainly, the present application may also set the determination rule of the delay time to the lower the priority level, and the shorter the delay time, which is not limited to the specific embodiment of the present application.

Step 302: Detect whether there is one active master service information according to the delay time, and the master master service information reflects whether there is an active master service role.

If priority level priority is set to 0, 1st, 2nd, ..., etc. in order of highest to lowest, level 0 represents the highest priority level, and each board is calculated by timeout=priority*1000ms. The delay time, the board with 0 priority level delay 0ms start detection whether there is a main control service information, the board with the priority level of 1 priority delay 1000ms start detection whether there is a main control service Information, with a level 2 priority board delay 2000ms start detection whether there is a main master service information, ..., and so on, the higher the priority level, the more it first detects whether there is a main master The service information, the first to determine whether it has to assume a role of the main master service.

Step 303: When it is detected that the main control service information does not exist, determine that the board role is the main control service role, and send an active main control service information.

Each board delays the corresponding delay time according to the priority rule to start detecting whether there is an active main control service information, and the main use service information reflects whether there is a main active service role, that is, When there is a primary master service role, an active master service information can be detected. Otherwise, when the master master service role does not exist, the master master service information cannot be detected. When the board detects that there is no information about the active master service, it indicates that there is no active role of the active master service. At this time, the probe board determines itself as the master service role and sends a master. With the master service information, it has been informed that the other board master master service role is already in place.

Step 304: When it is detected that there is one main control service information, connect the main control service information, and determine that the card role is an alternate main control service role.

The boards periodically detect whether there is an active main control service information according to a priority rule. When a board detects that there is an active main control service information, it indicates that the main main control service role is in place at this time. , then determine itself as the alternate master service role, and send a connection request to the board serving as the master master service role, the board serving as the master master service role receives the connection request and is allowed to serve The board connection of the standby master service role, the board serving as the standby master service role monitors the behavior of the board serving as the master master service role in real time through the primary master service information.

As a preferred implementation, after the step 304, the method further includes:

In step 305, the card serving as the standby master service role monitors whether the active main control service is running normally. If yes, the monitoring is continued. If not, the process returns to step 301 to restart the active/standby competition process.

The above-mentioned active/standby control competition step introduces the active/standby competition priority and the active main control service, so that the card with the main control capability can detect the main control service in a shorter time. After the detection timeout, the detection is faster. Exit the probe state and start the primary master service and determine the role of the board as the primary master. The other boards with the main control capability can ensure that the active main control service is detected within the detection timeout period. After the detection is completed, the detection status is quickly exited and connected to the main control service and the board is determined as the standby main control. After monitoring the disconnection of the active master service, the active/standby competition mechanism will be restarted, and the probe timeout period will be recalculated to make the system run efficiently.
