Description
Technical Field
The present application relates to the field of network technologies, and in particular, to a method and an apparatus for adjusting resource zones.
Background
Generally, a network device has a plurality of service modules for implementing different functions, and these functions generally require the use of table entry resources of the network device chip hardware. However, the table entry resources of the network device chip hardware are limited, so when there are at least two functions that need to use the same table entry resource area, the table entry resource area is generally divided into a plurality of table entry resource intervals, and the table entry resources of each interval are allocated to different functions for use.
When the network device is upgraded from the old version to the new version, it is assumed that the table entry resource interval allocated to the function a is expanded in the new version, and the expanded part of the table entry resource interval is allocated to the function B in the old version, and the function B has used the table entry resources in the part of the table entry resource interval. After the new version is upgraded, the function a may cover the part of the table entry resources, which may cause the part of the table entry resources to be lost, and the function B may be abnormal, which may even cause a network failure.

Detailed Description
The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
Generally, a network device has a plurality of service modules for implementing different functions, and these functions generally require using table entry resources of a network device chip hardware, such as table entry resources of an ASIC chip, for example, a routing table. Port aggregation, Access Control Lists (ACLs) and other functions of the network device generally require entry resources of the ASIC chip.
However, the table entry resources of the network device chip hardware are fixed and cannot be expanded, so when there are at least two functions that need to use the same table entry resource area at the same time, the table entry resource area is usually divided into a plurality of table entry resource intervals at present, and the table entry resources in different table entry resource intervals are allocated to different functions for use.
When the partitioned entry resource interval needs to be changed, for example, the entry resource interval allocated to a certain function needs to be expanded, which is usually realized by version upgrade. The new software version will generally improve the original version according to the user's requirement, and if the user needs to expand the table entry resource interval allocated to the function a, the table entry resource interval corresponding to the function a defined by the new software version is the expanded table entry resource interval. For example, the entry resource interval corresponding to the function a defined by the old software version is 248-255, and if the user needs to expand the entry resource interval corresponding to the function a, the entry resource interval corresponding to the function a defined by the new software version can be set to 240-255 according to the user's requirement.
Therefore, the user can expand the table resource interval corresponding to the function A only by upgrading the software version of the equipment.
However, the following problems may occur when the change of the table entry resource interval corresponding to a certain function is realized through version upgrade:
when the network device is upgraded from the first version to the second version, because the table entry resource interval corresponding to the function a defined by the second version is changed from the table entry resource interval corresponding to the function a defined by the first version, an intersection exists between the table entry resource interval corresponding to the function a defined by the second version and the table entry resource interval of the function B defined by the first version, and then, after the device is upgraded to the second version, the table entry resource of the function a recorded in the intersection is covered by the table entry resource of the function B. This may cause an abnormality in function a and in severe cases also cause a network failure.
Therefore, the present application provides a resource interval adjusting method, which adjusts the entry resource interval corresponding to each function according to whether an intersection exists in the entry resource intervals corresponding to each function defined by different versions before and after the upgrade of the network device, and whether entry resources are recorded in the intersection. Therefore, the loss of the table item resources caused by the adjustment of the table item resource interval is avoided.
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, fig. 1 is a flowchart of a resource interval adjusting method provided in the present application. In one embodiment, the method is applicable to a network device. As shown in fig. 1, the process includes the following steps:
As an embodiment, the first version in this step 101 is a software version currently used by the network device, and the second version is a new version to which the network device can be upgraded.
The second version may generally comprise, compared to the first version: new functions of the network equipment, modification of original functions of the network equipment, adjustment of table resource intervals of a certain function and the like.
Generally, to upgrade the software version of the network device from the first version to the second version, the second version needs to be written into a nonvolatile storage medium of the network device, such as a hard disk, and then the network device is restarted. And when the network equipment is restarted, the second version is loaded into the memory from the nonvolatile storage medium to run, so that the current software version of the network equipment is upgraded to the second version.
In order to avoid the entry resource loss caused by the adjustment of the entry resource interval in the second version, in this step 101, when the network device is restarted after being upgraded from the first version to the second version, it is checked whether an intersection exists between a first entry resource interval corresponding to the first function defined by the second version and a second entry resource interval corresponding to the second function defined by the first version.
As an embodiment, when checking whether there is an intersection between a first entry resource interval corresponding to a first function defined by a second version and a second entry resource interval corresponding to a second function defined by a first version, a function in which each entry resource interval defined by the second version is changed from the entry resource interval defined by the first version may be sequentially checked as the first function.
To facilitate understanding of this step 101, the following description is described with reference to fig. 2 by way of example, and fig. 2 is a schematic diagram of an entry resource interval provided in this embodiment of the present application.
It is assumed that the table entry resource intervals corresponding to the first function and the second function defined by the first version and the second version are as shown in fig. 2, that is, the second table entry resource interval corresponding to the second function defined by the first version is 0 to 246, and the first table entry resource interval corresponding to the first function defined by the second version is 245 to 255.
It may be determined that there is an intersection between the first entry resource interval corresponding to the first function of the second version definition and the second entry resource interval corresponding to the second function of the first version definition, where the intersection is 245-246.
The intersection may also represent a portion of the second version of the first entry resource interval corresponding to the first function that is extended compared to the third entry resource interval corresponding to the first function that is defined by the first version. This also corresponds to the table entry resource interval in the first version being divided into the intersection portion of the second function, in which the first function is divided.
In a specific implementation, there are a plurality of implementation manners of this step 102, which are described below by way of example and are not described herein again.
As an embodiment, if it is found that there is no intersection between the first entry resource interval corresponding to the first function defined by the second version and the second entry resource interval corresponding to the second function defined by the first version, the entry resource intervals corresponding to the first function and the second function may be directly determined as the entry resource intervals defined by the second version.
Specifically, the current table entry resource interval corresponding to the first function may be updated from the third table entry resource interval corresponding to the first function defined by the first version to the first table entry resource interval, and the current table entry resource interval corresponding to the second function may be updated from the second table entry resource interval to the fourth table entry resource interval corresponding to the second function defined by the second version.
Thus, the flow shown in fig. 1 is completed.
Through the process shown in fig. 1, according to the present application, after the device is upgraded from the first version to the second version, the entry resource intervals corresponding to the functions defined by the first version and the second version are adjusted according to whether an intersection exists between the entry resource intervals corresponding to the functions defined by the first version and the second version, and whether entry resources are recorded in the intersection, so that the entry resource loss caused by the adjustment of the entry resource intervals is avoided.
As an embodiment, after completing the above-mentioned flow of fig. 1, the network device continues to complete the restart according to the normal flow, such as performing a flow of recovering the configuration file.
The above step 102 is described below by way of example with reference to fig. 3:
referring to fig. 3, fig. 3 is a flowchart illustrating an implementation of step 102 provided in an embodiment of the present application. The process shown in fig. 3 is executed when it is checked through step 101 that there is an intersection between a first entry resource interval corresponding to a first function defined by a second version and a second entry resource interval corresponding to a second function defined by a first version. As shown in fig. 3, the process may include the following steps:
In an example, step 301 may first check whether the entry resource is recorded in the intersection determined in step 101, and if so, may further determine to which function of the network device the entry resource recorded in the intersection corresponds.
As an embodiment, the third entry resource interval and the second entry resource interval are different intervals in a defined chip hardware entry resource region;
the first table resource interval and the fourth table resource interval are different intervals in a defined chip hardware table resource area.
In practical application, the hardware table entry resource area of the same chip can be divided into two or more intervals, and the two or more intervals are respectively allocated to different functions for use.
Since any table resource corresponding to the second function is not recorded in the intersection, the device determines the table resource interval corresponding to the first function as the first table resource interval corresponding to the first function defined by the second version, which does not result in the loss of the resource table entry of the second function, and thus the current table resource interval corresponding to the first function can be updated to the first table resource interval. Correspondingly, since the first function and the second function use different intervals of the same table resource area, the current table resource interval corresponding to the second function can be updated to the fourth table resource interval corresponding to the second function defined by the second version. That is, the first function and the second function both use the entry resource interval defined by the second version.
It is convenient to understand the step 302, which is described below with reference to fig. 2 as an example:
referring to each table entry resource interval shown in fig. 2, if it is determined through the check in step 301 that no table entry resource of the second function is recorded in the intersection 245-246 between the first table entry resource interval corresponding to the first function and the second table entry resource interval corresponding to the second function, the current table entry resource interval corresponding to the first function may be updated to the first table entry resource interval, that is, the current table entry resource interval corresponding to the first function is updated to 245-255; and updating the table item resource interval corresponding to the second function to a fourth table item resource interval corresponding to the second function defined by the second version, namely updating the current table item resource interval corresponding to the second function to 0-244.
Since at least one entry resource corresponding to the second function is recorded in the intersection, if the device determines the current entry resource interval corresponding to the first function as the first entry resource interval corresponding to the first function defined by the second version, the entry resource of the second function in the intersection is covered by the entry resource of the first function and lost.
The entry resource interval for both the first function and the second function may be determined to be the entry resource interval that it defined in the first version. Specifically, the current table resource interval corresponding to the first function may be determined as a first table resource interval, and the table resource interval corresponding to the second function may be determined as a second table resource interval.
This is convenient to understand and is described below by way of example in connection with fig. 2:
referring to each table entry resource interval shown in fig. 2, if it is determined that at least one table entry resource of the second function is recorded in the intersection, for example, the table entry 245 records a table entry resource of the second function, the current table entry resource interval corresponding to the first function may be determined as a third table entry resource interval corresponding to the first function defined by the first version, that is, the current table entry resource interval corresponding to the first function is determined as 247 to 255, and the table entry resource interval corresponding to the second function is determined as 0 to 246 corresponding to the second table entry resource interval corresponding to the second function defined by the first version, according to the check in step 301.
Since the first entry resource interval of the first function defined by the second version is actually equivalent to the capacity expansion of the third entry resource interval of the first function defined by the first version, after this step 303, since the current entry resource interval corresponding to the first function is determined to be the third entry resource interval, it is equivalent to that although the network device is upgraded to the second version, the capacity expansion of the third entry resource interval corresponding to the first function defined by the first version is not performed, and the third entry resource interval corresponding to the first function defined by the first version is still used.
In order to meet the capacity expansion requirement of the user for the third entry resource interval, after step 303, some other steps may be further performed to implement the capacity expansion for the third entry resource interval, which is described in the following by way of example and is not described herein again.
The flow shown in fig. 3 is completed.
Through the process shown in fig. 3, the present application realizes that, in step 102, the current table resource interval corresponding to the first function and the current table resource interval corresponding to the second function are determined according to whether at least one table resource corresponding to the second function is recorded in the intersection.
It should be noted that fig. 3 illustrates only one implementation of the step 102, and is not intended to be limiting.
How to expand the third entry resource interval corresponding to the first function defined in the first version based on the execution of the step 303 is described as follows:
in an example, it may be first determined whether the user has a capacity expansion requirement for an entry resource interval corresponding to a first function defined in a first version.
As an embodiment, after executing step 303, query information may be sent to the user to query whether the user needs to expand the table resource interval corresponding to the first function defined by the first version.
In order to avoid that the user doubts the individual inquiry information, prompt information can be sent to the user to prompt the user that the upgrade of the network equipment does not expand the third entry resource interval corresponding to the first function in the first version.
The query information and the prompt information may be set according to an actual application scenario, for example, to avoid that a user who does not need to expand the capacity of the first function has a question about the prompt information in this embodiment, the prompt information may be added with a content that the second version is updated compared with the first version, and it is described that the version update does not expand the capacity of the table resource interval corresponding to the first function defined in the first version.
The prompt message may further indicate a reason for not expanding the first function, that is, there is an intersection between the first entry resource interval corresponding to the first function defined by the second version and the second entry resource interval corresponding to the second function defined by the first version, and entry resources corresponding to the second function are recorded in the intersection.
After determining that the user has a capacity expansion requirement for the table resource interval corresponding to the first function defined by the first version, capacity expansion can be performed in multiple ways.
For example, the main reason why the current table entry resource interval corresponding to the first function is determined as the third table entry resource interval corresponding to the first function defined by the first version through the above step 303 is that there is an intersection between the first table entry resource interval corresponding to the first function defined by the second version and the second table entry resource interval corresponding to the second function defined by the first version, and the table entry resource corresponding to the second function is recorded in the intersection.
Therefore, to expand the third entry resource interval corresponding to the first function defined in the first version, the current entry resource interval corresponding to the first function needs to be updated to the first entry resource interval, and it is ensured that the entry resource corresponding to the second function recorded in the intersection is not lost. Therefore, the entry resource corresponding to the second function recorded in the intersection can be transferred to other entries, and then the entry resource interval corresponding to the first function is expanded.
Generally, functions of the network device are not sequentially stored when storing the table entry resources, that is, if a second table entry resource interval corresponding to a second function defined by a first version is 0 to 246, where the table entry 246 records the table entry resources corresponding to the second function, and other table entries, such as table entry 1, may still not record the table entry resources corresponding to the second function.
Therefore, an empty entry of the unrecorded entry resource can be determined in a fourth entry resource interval corresponding to the second function defined by the second version, the entry resource corresponding to the second function recorded in the intersection is moved to the determined empty entry, and the entry resource corresponding to the second function recorded in the intersection is deleted.
During specific implementation, the empty table entry is determined in multiple ways, for example, whether table entry resources are stored in each table entry in the table entry resource interval is checked, and the table entry not storing the table entry resources is determined as the empty table entry; if a selection condition is further set, selecting an empty table entry meeting the condition from the empty table entries of the non-stored table entry resources; further, for example, information related to the empty entries of the non-stored resources may be sent to the user, selected by the user, and so on. This is not particularly limited by the present application.
After the entry resource corresponding to the second function recorded in the intersection is transferred to other entries, the current entry resource interval corresponding to the first function is updated to the first entry resource interval defined by the second version, that is, the entry resource interval corresponding to the first function defined by the first version is expanded, so that it is ensured that the entry resource corresponding to the second function recorded in the intersection is not lost.
In order to facilitate understanding of the above, the following description will be made by way of example with reference to fig. 2 and 4.
As shown in FIG. 2, there are intersections 245-246 between the first table resource interval corresponding to the first function defined by the second version and the second table resource interval corresponding to the second function defined by the first version. Referring to fig. 4, assuming that the entry resource corresponding to the second function is recorded in the entry 245, an empty entry of the unrecorded entry resource may be determined in a fourth entry resource interval corresponding to the second function defined by the second version. If it is determined 99-101 as an empty entry not recording the entry resource as shown in fig. 4, the entry resource recorded in the entry 245 may be stored in the determined empty entry, for example, stored in the entry 99, and the entry resource recorded in the entry 245 is deleted.
After that, the current table resource interval corresponding to the first function is updated to the first table resource interval, that is, the current table resource interval corresponding to the first function is updated from 247 to 255 to 245 to 255 according to each table resource interval shown in fig. 2, so that the capacity expansion of the table resource interval corresponding to the first function defined by the first version is realized.
As another embodiment, a prompt message may also be sent to the user after step 303 is executed to prompt the user that the network device has been upgraded to the second version but does not perform capacity expansion on the entry resource interval corresponding to the first function, and an operation instruction for performing capacity expansion manually is provided to the user, so that the user may perform capacity expansion manually by using the operation instruction.
So far, how to implement the description of expanding the capacity of the third entry resource interval corresponding to the first function defined by the first version is completed on the basis of executing the step 303. It should be noted that the above-mentioned embodiments are only examples and are not intended to limit the present application. In practical applications, the above embodiments may also be used in combination, and the specific combination method is not described in detail herein.
