In the existing communication equipment, especially in a frame type communication equipment, in order to stably operate a system, two main control boards are often required to undertake equipment management work, one main control board undertakes a main control role of the equipment, and the other main control board undertakes a standby main control role of the equipment. 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 and 1.3, two switch boards 1.4 and 1.5, and N service boards 1.6, 1.7. In the communication device 1.1, two main control boards 1.2 and 1.3 are connected to two switch boards 1.4 and 1.5 and N service boards 1.6 and 1.7. The two main control boards 1.2, 1.3 determine their respective board roles as the main control board and the standby control board through the main-standby competition mechanism in the communication device 1.1, and the selected main control board realizes the overall management control of the whole frame type communication device 1.1.

Moreover, if the number of slots of the frame-type device 1.1 is small, for example, if there are only six slots, the design that the frame-type device 1.1 relies on the dual-master-control board card to operate the master-slave competition mechanism may occupy too many slots of the frame, so that the number of other plug-in cards is limited, and thus, the service requirements cannot be met.
In addition, the main/standby competition mechanism relies on the two main control boards 1.2 and 1.3 to establish communication connection and send competition messages to each other, if the main control boards 1.2 and 1.3 are plugged or unplugged, or the time interval between the start of the two main control boards 1.2 and 1.3 is too long due to reasons such as hardware differences, the time for establishing communication connection between the two corresponding main control boards 1.2 and 1.3 becomes very long, and at this time, the start time of the system is slowed down by the operation of the whole main/standby competition mechanism.

Detailed Description
The following detailed description of embodiments of the invention is made with reference to the accompanying drawings.

The board cards comprise a main control board card, a switching board card, a service board card and the like, and the main control board card, the switching board card, the service board card and the like are all spliced together through a middle board, namely, all the board cards are spliced in a slot position of the middle board; communication connection is established between the board cards, and the communication connection can be established between the board cards in various ways.
The switch switching device SW is composed of an intelligent ASIC chip with a control function and an exchange function, the chip is provided with a plurality of interfaces, each interface in the plurality of interfaces can be configured into a channel with any other interface, an inter-board information channel between the board cards can be established by using the switch switching device SW, the communication connection of the board cards is realized, and the two-to-two interconnection of the board cards is realized. It should be noted that the inter-board information channel established by the device SW may be an ethernet-based information channel.
In addition, the inter-board information channel between the boards may be formed by dedicated signal lines connected through a midplane.
The method for determining the delay time comprises the following steps:
a. determining the position sequence number of a card slot of each board card and the function realized by each board card;
each board card can obtain a board slot position information and other on-line board card slot position information through the middle board, the board slot position information is information provided by the middle board to each board card, and the information reflects the slot position into which each board card is inserted, in the embodiment, the board slot position information provided by the middle board is represented by a group of high and low level signals, for example, 001 represents that the board slot position is 2 slots, and 011 represents that the board slot position is 4 slots; the slot position information of other on-line board cards is obtained by utilizing the orthogonal insertion of each board card on the middle plate to cause the signal change of a group of high and low levels on the middle plate, the group of signals indicate whether the board card is inserted into each slot position and the slot position information of each card, and the board acquires the level signals to judge the slot position information of other on-line board cards. For example, 001 indicates that a board is inserted into the 2 slot position, and 011 indicates that a board is inserted into the 4 slot position. The function of determining each board card to implement may be, for example, determining whether each board card belongs to a master board card or a switch board card, or determining whether each board card belongs to another service board card, or the like.
b. Determining the priority sequence of each board card according to the descending sequence or ascending sequence of the slot position serial numbers of each board card and the function type realized by each board card;
in this step, the priority of each board card can be determined according to the descending order or ascending order of the slot position serial numbers of each board card and the function realized by each board card. For example, the priority order of each board card is determined according to a rule that the slot serial number is in a descending order, that is, the smaller the slot serial number is, the higher the board card priority is, the priority of the master control board card is greater than that of the switch board card, the priority of the switch board card is greater than that of the service board card, and the like. It should be noted that, the priority is determined by comprehensively considering the slot serial numbers of the board cards and the functions of the board cards, and the specific corresponding rule may be specifically determined according to the actual situation, which is not limited by the present invention. For example, an external priority order may be initially arranged according to the principle that the priority of the master control board card is greater than that of the switch board card, and the priority of the switch board card is greater than that of the service board card, then the board cards with the same function, such as a plurality of service board cards, are arranged in descending order or ascending order according to the slot serial number to determine an internal priority order, and finally the final priority order is determined according to the external priority order and the internal priority order. The priority level corresponding to each board card function can also be changed according to actual conditions, for example, when the master control board card needs to be used for deep packet analysis, the priority rule can be modified to be that the priority of the switch board card is greater than that of the master control board card at the moment, and the like.
c. And determining the delay time of the board card starting detection according to a rule that the higher the priority is, the shorter the delay time is.
After the priorities of the boards are determined, the delay time of each board is determined according to a rule that the higher the priority is, the shorter the delay time is, so that the board with the higher priority has greater initiative and possibility to take the role of the main master control service. The specific implementation manner may be that priority levels are set to 0 level, 1 level, 2 level, and so on in order from high to low, where 0 level represents the highest priority level, and the delay time of each board card is calculated by using timeout ═ priority × 1000 ms. Of course, the present invention may also set the rule for determining the delay time to be shorter as the priority level is lower, and is not limited to the specific embodiment of the present invention.
If priority level priority is set to 0 level, 1 level, 2 level, etc. in sequence from high to low, where the 0 level represents the highest priority level, and the delay time of each board card is calculated by timeout 1000ms, the board card with the 0 level priority level delays 0ms to start detecting whether there is one primary main control service information, the board card with the 1 level priority level delays 1000ms to start detecting whether there is one primary main control service information, and the board card with the 2 level priority level delays 2000ms to start detecting whether there is one primary main control service information.
Each board card respectively delays corresponding delay time according to priority rules and then starts to detect whether a main control service message exists, wherein the main control service message reflects whether a main control service role exists currently, namely when the main control service role exists, the main control service message can be detected, otherwise, when the main control service role does not exist, the main control service message cannot be detected. When a board card detects that the main control service information does not exist, the board card indicates that the main control service role does not exist currently, at the moment, the detection board card determines the detection board card as the main control service role, and sends main control service information to inform other board cards that the main control service role is in place.
And step 304, when detecting that one main master control service information exists, connecting the main master control service information and determining the board card role as the standby master control service role.
The method comprises the steps that each board card detects whether main control service information exists or not according to priority rules, when the board card detects that one main control service information exists, the existing main control service role is in place, the board card determines the existing main control service role as a standby main control service role, a connection request is sent to the board card which plays the main control service role, the board card which plays the main control service role receives the connection request, the board card which plays the standby main control service role is allowed to be connected, and the board card which plays the standby main control service role monitors the behavior of the board card which plays the main control service role in real time through the main control service information.
As a preferred embodiment, after the step 304, the method further includes:
In the step of competing master/slave control right, the master/slave competing priority and the master/slave master control service are introduced, so that the board card with the master control capability can detect the master/slave master control service in a shorter time, and after the detection is overtime, the board card exits the detection state more quickly, starts the master/slave master control service and determines the role of the board as the master/slave. And other board cards with the main control capability can ensure that the main control service is detected within the detection timeout time, and after the detection is finished, the board quickly exits the detection state, is connected to the main control service and determines that the board is the standby main control, and after the condition that the main control service is disconnected is monitored, the main and standby competition mechanism is restarted, the detection timeout time is recalculated, and the system is operated efficiently.
