Detailed Description
Aiming at the problem that the existing control method of the router causes a single usage of the router and cannot meet the diversified demands of users, the embodiment of the present invention provides a control method of the router, an execution main body of the method may be a main control board in the router shown in fig. 1, and a flow is shown in fig. 2, and the execution steps are as follows:
s20: and powering on a main control board in the router.
S21: detecting whether a main control card is inserted into the router, and if detecting that the main control card is inserted into the router, executing S22; if it is detected that the master card is not inserted into the router, S23 is executed.
In the router shown in fig. 1, the main control board has the same hardware characteristics for the centralized main program and the distributed main program, and the card slot connected to the card slot adapter board 1 may be a service card, may also be a main control card, and may also not be inserted with any card. When a main control card is inserted into a card slot connected with the card slot adapter plate 1, namely the main control card is inserted into a router, the router is used as a distributed router; when a service card is inserted into the card slot connected to the card slot adapter board 1 or no card is inserted into the card slot, that is, when no master card is inserted into the router, the router is used as a centralized router. Therefore, after the router is started, the main control board in the router is powered on, the main control board firstly needs to detect whether the main control card is inserted into the router, and then determines the type of the router according to the detection result, thereby further determining the main program to be loaded.
S22: after receiving the distributed main program loading instruction sent by the main control card, the first distributed main program of the main control board is loaded, and S24 is executed.
If the main control card is inserted into the router, the first distributed main program can be loaded after a distributed main program loading instruction sent by the main control card is received, and the distributed main program loading instruction is sent after the main control card loads the second distributed main program. Because the first distributed main program is loaded on the main control board and the second distributed main program is loaded on the main control card, the router can be used as a distributed router at the moment.
S23: the centralized main program of the main control board is loaded, and S24 is executed.
If the master control card is not inserted into the router, the master control board can directly load the centralized main program, and the router can be used as a centralized router.
S24: and powering on a service card included in the router to complete the starting of the router.
Usually, the router includes at least one service card, and after the main control board finishes loading the required program, all the service cards included in the router may be powered on, thereby completing services such as starting the router, forwarding a message by the router, and the like.
In the scheme, when the main control board detects that the main control card is inserted into the router, the main control board loads the first distributed main program, the router serves as a distributed router, when the main control board detects that the main control card is not inserted into the router, the main control board loads the centralized main program, the router serves as a centralized router, and therefore the router can serve as the distributed router or the centralized router according to actual needs, and the purposes of the router are diversified.
Each step in the above-described control method of the router is described in detail below.
Specifically, the implementation process of detecting whether the master card is inserted into the router in S21, as shown in fig. 3, includes:
s211: the process begins.
S212: judging whether the state bit of the main control card is set, if so, executing S213; if the status bit of the host card is not set, go to step S214.
S213: and detecting the insertion of the master control card in the router.
S214: and detecting that the master control card is not inserted into the router.
There are many methods for detecting whether a master control card is inserted into a router, and the router shown in fig. 1 is taken as an example to illustrate, the master control board may determine according to whether a set master control card status bit of a Complex Programmable Logic Device (CPLD) is set, and if the set master control card status bit is set, it indicates that the master control card is inserted into the router; if the status bit of the master control card is not set, it indicates that the master control card is not inserted into the router. The main control board can judge whether the main control card is inserted into the router or not through the steps S211-S214, and the method is simple, effective and high in accuracy.
Specifically, the implementation process of the first distributed main program loaded on the main control board in S22 is shown in fig. 4, and includes:
s221: and acquiring the header information of the stored program installation package.
The main control board usually stores a program installation package, and the program installation package in the prior art only contains one program, not a distributed main program, but a centralized main program, so that the router can only be used as a distributed router or a centralized router. The header information of the stored program installation package may have a plurality of setting manners, and the composition structure of the program installation package in the embodiment of the present invention is shown in fig. 5, where each program installation package has the header information, and the header information stores the centralized main program of the main control board, the second distributed main program and the second distributed loader of the main control card, the first distributed main program and the first distributed loader of the main control board, and others (e.g., a web-Programmable Gate Array (FPGA) upgrade package, a compression format of the program installation package, etc.). The program installation package in the embodiment of the invention comprises the distributed main program and the centralized main program, so that the main control board can select the programs as required, and the router can be used as a distributed router or a centralized router as required.
S222: and searching the compression format of the stored program installation package from the packet header information.
S223: and decompressing the stored program installation package according to the compression format.
S224: and acquiring sub-installation items corresponding to the identification information of the main control board and the main program identification from the decompressed stored program installation package to obtain a first distributed main program of the main control board.
Each installation item in the stored program installation package may be stored according to a set rule, and when the set rule is different, the method for acquiring the sub installation item corresponding to the identification information of the main control board and the main program identification is also different, and the stored program installation package shown in fig. 5 is described below. As shown in fig. 5, the respective installation items of the stored programs are arranged from left to right, the centralized main program of the main control board is used as a main installation item, and the second distributed main program and the second distributed loader of the main control card, and the first distributed main program and the first distributed loader of the main control board are used as sub installation items. Because the identification information and the main program identification of the main control board are also stored in the centralized main program of the main control board, in the step, the identification information and the main program identification of the main control board can be searched from the sub installation items, if the identification information and the main program identification of the main control board are searched, the corresponding sub installation items can be obtained, and the first distributed main program of the main control board is obtained.
The identification information of the main control board may be set according to actual needs, for example, may be set as a hardware identifier, a code, and the like of the main control board.
S225: and loading a first distributed main program of the main control board.
After the first distributed main program is obtained, the main control board can load the first distributed main program, so that the router can be used as a distributed router.
The loading of the first distributed main program on the main control board can be realized through steps S221-S225.
Specifically, the implementation process of the centralized main program for loading the main control board in S23 is shown in fig. 6, and includes:
s231: and acquiring the header information of the stored program installation package.
S232: and searching the compression format of the stored program installation package from the packet header information.
S233: and decompressing the stored program installation package according to the compression format.
S234: and acquiring a main installation item corresponding to the identification information of the main control board from the decompressed stored program installation package to obtain a centralized main program of the main control board.
Each installation item in the stored program installation package may be stored according to a set rule, and when the set rule is different, the method for obtaining the main installation item corresponding to the identification information of the main control board and the main program identification is also different, and the stored program installation package shown in fig. 5 is described below. As shown in fig. 5, the respective installation items of the stored programs are arranged from left to right, the centralized main program of the main control board is used as a main installation item, and the second distributed main program and the second distributed loader of the main control card, and the first distributed main program and the first distributed loader of the main control board are used as sub installation items. Because the sub-installation items corresponding to the distributed main program of the main control board are arranged behind the main installation item corresponding to the centralized main program of the main control board, in the step, the identification information and the main program identification of the main control board can be searched from the main installation item, if the identification information and the main program identification of the main control board are searched, the corresponding main installation item can be obtained, and the centralized main program of the main control board is obtained.
S235: and loading the centralized main program of the main control board.
Except for S234, the process of loading the centralized main program of the main control board is the same as the process of loading the first distributed main program of the main control board, and is not described herein again.
Whether the router is used as a centralized router or a distributed router, later upgrade maintenance is very important. When the master control card is not inserted into the router, namely the router is used as a centralized router, the upgrading method of the program installation package is the same as that of the prior art, and the upgraded program installation package is sent to the master control board for upgrading through an Ethernet management port of the master control board or an external memory; when the master control card is inserted into the router, that is, when the router is used as a distributed router, the step of updating is different when the time of receiving the updated program installation package is different, and the following description will take two cases of receiving the updated program installation package before and after loading the first distributed main program of the master control board in S22 as an example.
In the first case, before the first distributed main program of the main control board is loaded, the upgraded program installation package sent by the main control card is received, and the upgraded program installation package is used for replacing the stored program installation package.
Under the condition, because the main control board does not load the first distributed main program yet, the received upgraded program installation package sent by the main control card can be directly replaced by the stored program installation package, and when the first distributed main program of the main control board is subsequently loaded, the first distributed main program in the upgraded program installation package can be directly loaded, so that equipment upgrading can be directly completed.
In the second case, after the first distributed main program of the main control board is loaded, the upgraded program installation package sent by the main control card is received, the upgraded program installation package is used for replacing the stored program installation package, and the router is restarted.
In this case, since the main control board has already loaded the first distributed main program, and at this time, the upgraded program installation package sent by the main control card is received, the router needs to be restarted, so that the control method of the router is executed again, and it is ensured that the first distributed main program after being upgraded is loaded by the main control board, thereby completing the equipment upgrade.
Specifically, the implementation process of powering on the service card included in the router in S24 is shown in fig. 7, and includes:
s241: each card slot of the router is scanned one by one.
S242: a card slot into which a service card is inserted is determined.
S243: and powering on the service card in the determined card slot.
The router usually includes a plurality of card slots, and the main control board can scan each card slot of the router one by one when determining the service card included in the router, determine the card slot into which the service card is inserted, and finally power on the service card in the determined card slot, thereby realizing power on of all the service cards included in the router.
Based on the same inventive concept, an embodiment of the present invention provides a method for controlling a router, where an execution main body of the method is a main control card in the router shown in fig. 1, and a flow is shown in fig. 8, where the execution steps are as follows:
s81: and after the main control card in the router is powered on, loading a second distributed main program of the main control card.
After the router inserted with the main control card is started, the main control card in the router is powered on at the same time, and after the main control card is powered on, the second distributed main program of the main control card is loaded.
S82: and sending a distributed main program loading instruction to a main control board in the router so that the main control board loads a first distributed main program of the main control board.
When the connection mode of the main control card and the main control board is different, the distributed main program loading instruction is also different, for example, when the main control card and the main control board are connected through a Peripheral Component Interconnect Express (PCIE) bus, the main control card may send the distributed main program loading instruction to the main control board through the PCIE.
In the scheme, when the main control board detects that the main control card is inserted into the router, the main control board loads the first distributed main program, the router serves as a distributed router, when the main control board detects that the main control card is not inserted into the router, the main control board loads the centralized main program, the router serves as a centralized router, and therefore the router can serve as the distributed router or the centralized router according to actual needs, and the purposes of the router are diversified.
Each step in the above-described control method of the router is described in detail below.
Specifically, the implementation process of the second distributed main program of the main control card loaded in S81, as shown in fig. 9, includes:
s811: and acquiring the header information of the stored program installation package.
S812: and searching the compression format of the stored program installation package from the packet header information.
S813: and decompressing the stored program installation package according to the compression format.
S814: and acquiring sub-installation items corresponding to the identification information of the main control card and the main program identification from the decompressed stored program installation package to obtain a second distributed main program of the main control card.
S815: and loading a second distributed main program of the main control card.
The process of loading the second distributed main program of the main control card is the same as the process of loading the first distributed main program of the main control board, and the detailed description is omitted here.
Whether the router is used as a centralized router or a distributed router, later upgrade maintenance is very important. When the master control card is not inserted into the router, namely the router is used as a centralized router, the upgrading method of the program installation package is the same as that of the prior art, and the upgraded program installation package is sent to the master control board for upgrading through an Ethernet management port of the master control board or an external memory; when a master control card is inserted into a router, that is, when the router is used as a distributed router, the master control card usually first receives an upgraded program installation package, and determines whether the master control card needs to be sent to a master control board for device upgrade, which specifically includes: after receiving the upgraded program installation package, determining whether the upgraded program installation package is the same as the stored program installation package; and if the upgraded program installation package is different from the stored program installation package, sending the upgraded program installation package to the main control board so that the main control board replaces the stored program installation package with the upgraded program installation package.
