In order to solve the above-described problems, according to an embodiment of the present disclosure, there is provided a firmware version compatibility management method embodiment, it is to be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different from that herein.
In this embodiment, a firmware version compatibility management method is provided, fig. 1 is a flowchart of a firmware version compatibility management method according to an embodiment of the present disclosure, and as shown in fig. 1, the method may be applied to a white box frame switch side, for example, a compatibility management process of the white box frame switch is taken as an execution main body, where the white box frame switch is a device that combines a white box switch and a frame switch, where the white box switch is a flexible and efficient network device, and a user may deploy different applications and services with personalized features on the same hardware system as required. The method has the function of decoupling software, can reduce cost and improve use flexibility, builds different components and modules for special requirements of manufacturers, and is widely applied to large-scale data centers. The biggest bright spot of the white box switch is the strong openness, so the white box switch has richer choices in terms of operating systems, software and the like compared with the traditional switch.
SONIC is one of the currently popular white-box switches NOS, SONIC can be regarded as a software set for constructing functions required by network equipment (such as switches), and a large amount of existing open source projects, open source technologies, automatic configuration tools and the like are used, so that the method has the advantages of extremely strong expansibility and network operation and maintenance, and can be very conveniently used for realizing non-stop deployment or upgrading application in a production environment.
Specifically, in fig. 1, the flow of the method includes the following steps:
step S101, obtaining a line card type of a target line card and a reference firmware version of a logic device of the target line card, where the target line card includes a first firmware corresponding to the reference firmware version.
Optionally, in the white box-frame switch, linux is used as an operating system, and a monitoring program in the system is written in a language C or python, and is monitored and processed by using process management software commonly used in Linux.
As shown in fig. 2, fig. 2 is a schematic diagram of a hardware configuration of firmware version compatibility management according to an embodiment of the present disclosure, a line card uses a CPLD of a common model as a logic device, a reference firmware version on a target line card is stored in a storage medium inside the CPLD itself, and a firmware version provided for loading and starting of the CPLD of the target line card is stored in an SPI Flash on a board of the machine frame on the machine frame, and is connected with the CPLD of the line card through an SPI bus. In addition, a preset compatibility list (all stored in the machine frame are target firmware versions compatible with the machine frame, and fig. 2 is called a standby version) is stored in a nonvolatile storage medium used by the machine frame NOS.
Therefore, when the compatibility management process of the white box switch detects that a new line card, such as a target line card, is inserted, the line card type of the target line card and the firmware version of the logic device of the target line card are acquired, which is referred to herein as a reference firmware version. Meanwhile, a first firmware is arranged in the target line card, the firmware version of the first firmware is a reference firmware version, and the firmware version of the first firmware is actually upgraded or downgraded in subsequent firmware version management.
Step S102, matching the reference firmware version with a preset compatibility list in the machine frame, and determining whether the reference firmware version exists in the preset compatibility list, wherein the preset compatibility list comprises a plurality of target firmware versions which can be compatible with the machine frame.
Optionally, after the reference firmware version is read by the compatibility management process, the reference firmware version is matched with a plurality of target firmware versions which are stored in a preset compatibility list in the machine frame and can be compatible with the machine frame, and then whether the reference firmware version exists in the preset compatibility list is determined.
It will be appreciated that the criteria for determining whether the reference firmware version exists in the predetermined compatibility list is to check whether the reference firmware version is any target firmware version.
Step S103, determining a target channel for loading the first firmware according to the matching result or determining the target channel for loading the first firmware according to the matching result and the line card type.
Optionally, as can be seen from the above, the criterion for determining whether the reference firmware version exists in the preset compatibility list is to check whether the reference firmware version is any target firmware version, and a matching result is obtained. And then obtaining a loading target channel of the first firmware according to the matching result. In addition, when the loading target channel cannot be obtained only through the matching result, the loading target channel is obtained by combining the matching result with the line card type of the target line card.
Step S104, initializing the target line card based on the target channel to realize the version management of the reference firmware version.
Optionally, after the loaded target channel is obtained, the target line card can be initialized, so that upgrade or downgrade management of the first firmware is realized, and compatibility of the upgraded or downgraded reference firmware version is adapted to the frame.
In the embodiment of the disclosure, a preset compatibility list containing a plurality of target firmware versions compatible with a machine frame is arranged in the machine frame, the preset compatibility list is used for matching the reference firmware version of a logic device of a target line card, and a target channel for initializing and loading the target line card is determined according to a matching result or a line card type of the target line card, so that version management of the reference firmware version of the target line card is realized, the situation that the line card is not available due to incompatibility of the reference firmware version of the target line card is prevented, flexible management of the reference firmware version of the target line card is realized, the running reliability and stability of the whole data center network are improved, the risk of service loss caused by initializing the target line card is prevented, and the problems that the conventional frame switch cannot flexibly adjust the firmware compatibility version, influence service operation and increase the data loss risk of a data center when managing the firmware compatibility of the line card and the machine frame are solved.
In some alternative embodiments, determining a target channel for loading the first firmware according to the matching result includes:
if the reference firmware version is matched with any target firmware version, determining that the reference firmware version exists in a preset compatibility list;
and taking the first channel as a target channel, and loading the first firmware, wherein the first channel is an original channel when the logic device of the target line card supports loading the firmware.
Optionally, if the reference firmware version is matched with the target firmware version and the reference firmware version is matched with the target firmware version, it is indicated that the reference firmware version exists in the preset compatibility list, and then the logic device of the target line card is utilized to support the original channel when loading the firmware, and the target line card is directly transferred to the line card initialization process, and initialization is started.
In the embodiment of the disclosure, if the reference firmware version exists in the preset compatibility list, it is indicated that the firmware version between the target line card and the machine frame has compatibility, and then the first firmware is loaded by using the original channel when the firmware is loaded, so that the data processing process is saved.
In some optional embodiments, determining a target channel for loading the first firmware according to the matching result and the line card type includes:
if the reference firmware version is not matched with any target firmware version, determining that the reference firmware version does not exist in the preset compatibility list;
and determining a target channel for loading the first firmware according to the existing version of the local storage of the frame and the type of the line card.
Optionally, if the reference firmware version matches the target firmware version, when the reference firmware version is not matched with the target firmware version, the reference firmware version is not in the preset compatibility list, and the line card type of the target line card is checked, that is, the CPLD firmware version of the target line card is checked, whether the existing SPI Flash version in the self frame can be provided for the line card of the type or not is determined, and then a target channel for loading the first firmware is determined.
In the embodiment of the disclosure, if the reference firmware version does not exist in the preset compatibility list, it is indicated that the firmware version between the target line card and the machine frame does not have compatibility, and the loaded target channel is obtained according to the existing version stored locally in the machine frame and the line card type, so that the service interruption time is reduced.
In some alternative embodiments, determining a target channel for loading the first firmware based on the existing version of the local storage of the subrack and the line card type includes:
acquiring an applicable relation between an existing version locally stored in a machine frame and a line card type;
and under the condition that the existing version is suitable for the line card type, loading the first firmware by taking the second channel as a target channel, wherein the second channel is a channel for supporting loading of the second firmware for a logic device on the machine frame, and the second firmware is the firmware with the firmware version contained in the machine frame being the target firmware version.
Optionally, determining the application relation between the existing SPI Flash version in the machine frame and the line card type, writing the SPI Flash version into a CPLD register generally managed by the machine frame when the existing SPI Flash version is applicable to the line card type, switching the reference version of the target line card, namely the CPLD firmware loading source, to a second channel for supporting loading the second firmware by a logic device on the machine frame, and then transferring the line card initialization process to initialize the target line card.
In the embodiment of the disclosure, when an incompatible target line card is encountered, the method can adapt to the type of the line card according to the existing version stored locally in the machine frame, and under the condition of adaptation, the logic device on the machine frame supports loading the second firmware to load the first firmware through the channel for loading the second firmware, so that the normal operation of the subsequent service can be realized.
In some optional embodiments, after obtaining the correspondence between the existing version stored locally by the subrack and the line card type, the method further includes:
acquiring user configuration information under the condition that the existing version is not suitable for the type of the line card;
and loading the first firmware by taking the second channel as a target channel according to the user configuration information, or stopping initializing the target line card according to the user configuration information.
Optionally, when the existing SPI Flash version of the machine frame is suitable for the line card type, a compatibility management process is required to check the user configuration to see whether the user configuration allows the target line card to automatically upgrade the firmware to the compatible version when the target line card is inserted, so as to obtain a target channel for loading the first firmware, or to stop initializing the target line card according to the user configuration information.
In the embodiment of the disclosure, when an incompatible target line card is encountered, the method can adapt to the type of the line card according to the existing version stored locally in the machine frame, and under the condition of the incompatibility, the configuration information set by the user is acquired to further determine the loading target channel, and if the reference firmware version is completely unusable or compatible, the target line card can be prevented from entering an initialization flow, and service loss caused by initialization of the target line card is prevented.
In some alternative embodiments, loading the first firmware with the second channel as the target channel according to the user configuration information includes:
determining whether the reference firmware version of the target line card is allowed to be automatically adjusted to the target firmware version according to the user configuration information;
if so, judging whether the existing version in the machine frame contains the target firmware version or not;
the method comprises the steps that if an existing version in a machine frame does not contain a target firmware version, the target firmware version is obtained from a version server through a network;
and switching the target channel to the second channel, and loading the first firmware based on the second channel.
Optionally, if the user configuration allows the target line card to automatically upgrade the reference firmware version to the compatible target firmware version when inserting, the compatibility management process first checks whether the CPLD firmware version available for the type of line card exists on the machine frame itself, if not, it can request downloading from the version server with the IP address stored in advance through the network (as in fig. 2, the machine frame is connected with an external server, and a standby version capable of realizing compatibility exists in the external server), after the target firmware version is obtained from the version server, upgrades the version in the SPI Flash in the machine frame by using the lossless switching transmission mode, upgrades the version to the target firmware version, then switches the first firmware loading source to the second channel on the machine frame for loading the second firmware, and enters the initialization flow.
The above is an upgrade procedure with reference to firmware versions. The degradation process also requires that the target firmware version is first obtained from the version server through the network, and the reason for incompatibility of the version of the reference firmware version with the target firmware version is that the version is too high, so that the reference firmware version needs to be degraded. And then degrading the version in the SPI Flash in the machine frame by using a lossless switching transmission mode, degrading the version to a target firmware version, switching a second channel for loading second firmware from a first firmware loading source to the machine frame, and entering a line card initialization flow.
It should be noted that, when the CPLD firmware version of the subrack is upgraded or downgraded, both the standby version in the preset compatibility list of the subrack in fig. 2 and the version stored in the SPI Flash in the subrack are upgraded or downgraded together. Meanwhile, a register is arranged in the overall management CPLD on the machine frame, so that the CPLD firmware of the target line card can be selected from which target channel to execute loading, and then an initialization flow is entered, and management of the CPLD firmware version of the target line card is realized.
In the embodiment of the disclosure, if the user configuration information sets that the reference firmware version is allowed to be automatically adjusted to the target firmware version, the firmware version of the logic device on the storage medium of the machine frame can be updated more quickly, so that the service interruption time caused by updating is reduced.
In some optional embodiments, stopping initializing the target line card according to the user configuration information includes:
determining whether the reference firmware version of the target line card is allowed to be automatically adjusted to the target firmware version according to the user configuration information;
if not, stopping initializing the target line card.
Optionally, if the user configuration does not allow the target line card to automatically upgrade the reference firmware version to the compatible target firmware version during insertion, the target line card is prevented from entering the initialization process, and the target line card error indicator light may be turned on to prompt the user to replace the target line card, and meanwhile, the information that the insertion of the target line card is refused is recorded in the NOS.
In the embodiment of the disclosure, if the user configuration information sets that the reference firmware version is not allowed to be automatically adjusted, the reference firmware version which cannot be used or is compatible is present, so that the target line card can be prevented from entering an initialization flow, and service loss caused by initializing the target line card is prevented.
In some alternative implementations, as shown in fig. 3, fig. 3 is an overall flow diagram of firmware version compatibility management according to an embodiment of the disclosure, and the specific flow is as follows:
