The processes may correspond to methods, software implementations, hardware implementations, and so on.
Example one
Fig. 1B is a flowchart of a method for starting a switch according to an embodiment of the present invention, where the method is applicable to a case of quickly starting a switch, and the method may be executed by a switch starting apparatus according to an embodiment of the present invention, where the apparatus may be implemented in a software and/or hardware manner. As shown in fig. 1B, the method specifically includes the following operations:
and step S101, resetting and starting the CPU and the exchange chip when the power is on.
Wherein, this embodiment is applied to the switch system, and the switch system specifically includes: CPU, exchange chip and memory. And when the switch is powered on, the system firstly resets and starts the CPU and the switching chip so as to ensure that the CPU and the switching chip can work normally.
Optionally, before resetting and starting the CPU and the switch chip during power-on, the method may further include: acquiring service data of a switching chip under the normal operation state of a switch system, wherein the service data comprises the waiting time of each service type; and storing the service data into a memory.
Specifically, in this embodiment, before the CPU and the switch chip are reset and started, that is, in a normal operating state where the switch system is not powered off, the service data of the switch chip is acquired, and the acquired service data is stored in the memory. The service data comprises: the register address, the register value, whether to actively wait for the identifier, the waiting time, and the like of each service, wherein the waiting time represents the starting time corresponding to each service type when the service configuration of the switch chip is performed, because the time constraint is usually required to be followed when the register of the chip is configured, and the corresponding time constraint is also required to be followed when the register of the chip is configured by the bootstrap program. An example of traffic data is shown in table 1 below:
TABLE 1
| Register address | Register value | Whether to actively wait for identification | Waiting time |
| Address 1 | Register value 1 | Y | 1s |
| Address 2 | Register value 2 | N | 2s |
| Address 3 | Register value 3 | Y | 0.5s |
| … | … | … | … |
However, in the present embodiment, the description is given only by way of example in table 1, and the specific format and the specific number of the service data stored in the memory are not limited.
Step S102 loads a boot program from the memory, and performs hardware initialization of the switch by the boot program.
Specifically, in the present embodiment, the BootLoader is stored in the memory, so that after the CPU and the switch chip are reset and started, the boot program is loaded from the memory, the loaded boot program is run in the CPU, and the hardware initialization of the switch is executed by the loaded boot program in the present embodiment.
The hardware initialization of the switch is implemented by running a bootstrap program to perform hardware self-test of the switch. The hardware for self-test in this embodiment includes a CPU, a switch chip, and a memory in the switch system, and may also include hardware of other structures in the switch. The hardware self-check of the switch is carried out by running the bootstrap program, so that whether the started CPU or the switching chip is abnormal or not can be found in time, and the self-repair can be carried out in time when the abnormality occurs.
Step S103, configuring the switch chip through the bootstrap program, so that the configured switch chip directly implements forwarding communication of the service.
Optionally, configuring the switch chip through the bootstrap program may include: carrying out initialization configuration on the exchange chip through a bootstrap program; and reading the service data from the memory through the bootstrap program, and performing service configuration on the exchange chip after the initialization configuration according to the service data.
Optionally, the initializing configuration of the switch chip by the bootstrap program may include: and setting basic forwarding function parameters of the switching chip through a bootstrap program, wherein the basic forwarding function parameters comprise forwarding port information.
Optionally, performing service configuration on the switch chip after the initialization configuration according to the service data may include: and setting the service starting time of the switching chip according to the waiting time of each service type so that the switching chip executes the service according to the starting time.
Specifically, in this embodiment, when the hardware initialization of the switch is executed through the bootstrap program, the hardware self-test of the switch is completed, and it is determined that there is no abnormal condition in the hardware, the initialization configuration is performed on the switch chip through the bootstrap program, that is, the basic forwarding function parameter setting is performed on the switch chip to prepare for subsequent service configuration. The basic forwarding function parameter in this embodiment may specifically include forwarding port information or forwarding path information, for example, traffic is forwarded according to the specified path x through the port 1, which is, of course, only an example in this embodiment and is not limited to a specific type of the basic forwarding function parameter.
After the initialization configuration of the switching chip is completed, the business data recorded and stored by the switch in the normal running state before the power failure is read from the memory through the bootstrap program, and the business configuration is carried out on the initialized switching chip according to the obtained business data. For example, the register value in the service data in table 1 may include status information and related parameters of each service before power off, and since the service data further includes a waiting time, when the switching chip is configured for a service, the service start time of the switching chip may be specifically set according to the waiting time of each service type, so that the switching chip executes the service based on the acquired service status information and related parameters according to the start time. Therefore, after the service configuration is completed for the switching chip according to the service data, the switching chip can immediately recover the service execution state before power failure according to the configuration content, so that the service forwarding communication is executed based on the switching chip after the service configuration. Therefore, the normal forwarding speed of the switch from power-on to service implementation in the embodiment can reach within 5 seconds. Therefore, when software configuration is not needed to be carried out at the final stage of the starting process, the switching chip is configured based on the SDK, and the recovery delay of the communication forwarding function is caused.
According to the technical scheme of the embodiment of the invention, when hardware initialization is carried out on the switch system according to the loaded bootstrap program and the condition that the hardware such as a CPU, a switching chip, a memory and the like in the switch system is abnormal is determined, the switching chip is directly configured through the bootstrap program loaded from the memory without waiting for the completion of loading of an operating system and the completion of operation execution such as CPU peripheral drive and the like, and the switching chip and software are synchronously configured based on the SDK in the switch software after starting, so that the switch can complete configuration and quickly enter normal service forwarding after being powered on, and the switch is quickly started.
Example two
Fig. 2 is a flowchart of a method for starting a switch according to an embodiment of the present invention, where the embodiment is based on the foregoing embodiment, and after reading pre-stored service data from a memory and performing service configuration on a switch chip according to the service data, the method further includes: loading the switching operating system from the memory by the bootstrap program; starting an exchange operating system, and driving a peripheral of the CPU based on the exchange operating system; and starting the switching software, and performing software configuration on the software development kit SDK through the switching software so as to keep the SDK and the switching chip in information synchronization. The method of the embodiment specifically includes the following operations:
step S201, resetting and starting the CPU and the exchange chip when power is on.
Optionally, before resetting and starting the CPU and the switch chip during power-on, the method may further include: acquiring service data of a switching chip under the normal operation state of a switch system, wherein the service data comprises the waiting time of each service type; and storing the service data into a memory.
In step S202, a boot program is loaded from the memory, and hardware initialization of the switch is performed by the boot program.
Step S203, configuring the switch chip through the bootstrap program, so that the configured switch chip directly implements forwarding communication of the service.
Optionally, configuring the switch chip through the bootstrap program may include: carrying out initialization configuration on the exchange chip through a bootstrap program; and reading the service data from the memory through the bootstrap program, and performing service configuration on the exchange chip after the initialization configuration according to the service data.
Optionally, the initializing configuration of the switch chip by the bootstrap program may include: and setting basic forwarding function parameters of the switching chip through a bootstrap program, wherein the basic forwarding function parameters comprise forwarding port information.
Optionally, performing service configuration on the switch chip after the initialization configuration according to the service data may include: and setting the service starting time of the switching chip according to the waiting time of each service type so that the switching chip executes the service according to the starting time.
Step S204, starting the exchange software in the CPU, and performing software configuration on the software development kit SDK through the exchange software so as to keep the SDK and the exchange chip in information synchronization.
In this embodiment, before the swap software in the CPU is started, the swap operating system is loaded from the memory by the boot program, and then the swap operating system is started, and the peripheral of the CPU is driven based on the swap operating system. After the switch is powered on for 5 seconds to configure the switching chip, the switching chip can immediately recover the communication forwarding function of the service. The memory also contains the exchange operating system, so the exchange operating system is loaded from the memory through the bootstrap program to load the bootstrap program into the CPU. After the swap operating system is loaded to the CPU, the CPU starts the swap operating system, and drives the peripheral devices of the CPU, such as a display, a modem, a mouse, and the like, based on the swap operating system.
Optionally, the software configuration of the software development kit SDK by exchanging software may include: reading the basic forwarding parameters of the switching chip through switching software, and initializing the forwarding function of the SDK according to the result of the reading operation; performing read operation and write operation on the non-forwarding function parameter of the switching chip through switching software, and performing non-forwarding function initialization on the SDK according to the result of the read operation and the write operation, wherein the non-forwarding function parameter comprises: access control list ACL information and quality of service QoS information.
In this embodiment, after the configuration of the switch chip is performed and the peripheral of the CPU is driven based on the loaded switching operating system, the switching software needs to be started after the hardware setting of the switch is completed, and the configuration is performed from the software layer of the switch, so as to ensure the consistency of the configuration information of the software layer and the hardware layer.
Specifically, when the software layer of the switch is configured, the SDK is configured through the started switch software, and the SDK includes necessary modules and unnecessary modules. The necessary modules are mainly used for functions related to service forwarding communication; the non-essential modules are mainly used for functions not related to traffic forwarding communication. Because the necessary modules have already initialized and configured the switch chip through the bootstrap program in the hardware level, but the SDK of these configuration information in the software level is unable to know, so in order to ensure the synchronization of the configuration information of the software level and the hardware level, and not to affect the service that has been recovered on the switch chip, the basic forwarding parameters of the switch chip are only read through the switch software, and the forwarding function of the SDK is initialized according to the result of the read operation, and the SDK does not perform the write operation of the switch chip, thereby recovering the software configuration of the SDK. For unnecessary modules in the SDK that are not related to service forwarding communication, normal initialization is required to perform read and write operations on the switch chip. For example, for the non-forwarding function parameter of the switch chip: and performing read operation and write operation on Access Control List (ACL) information, Quality of Service (QoS) information and the like, and performing non-forwarding function initialization on the SDK according to the results of the read operation and the write operation. Certainly, the SDK also includes a service function module, so that the switch software can also continue to initialize each switch function module to recover the stored service, and since the bootstrap program has already recovered the service configuration related to the switch chip, only the software layer is recovered at this time, and the hardware layer of the chip does not need to be configured again, so that the synchronization of software and hardware is maintained, and the recovered service is not affected.
According to the technical scheme of the embodiment of the invention, when hardware initialization is carried out on the switch system according to the loaded bootstrap program and the condition that the hardware such as a CPU, a switching chip, a memory and the like in the switch system is abnormal is determined, the switching chip is directly configured through the bootstrap program loaded from the memory without waiting for the completion of loading of an operating system and the completion of operation execution such as CPU peripheral drive and the like, and the switching chip and software are synchronously configured based on the SDK in the switch software after starting, so that the switch can complete configuration and quickly enter normal service forwarding after being powered on, and the switch is quickly started. And after the switching chip completes configuration and can normally forward the service, the software layer is configured, so that the synchronization of the software layer and the hardware layer is ensured to be realized under the condition of not influencing the recovered service.
