Detailed Description
The core of the invention is to provide a method, a system and a device for expanding the memory of the switch, which can automatically expand the available memory capacity of the switch without manual operation of a user when the available memory capacity of the switch is insufficient, thereby improving the user experience.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for expanding a memory of a switch according to an embodiment of the present invention.
The memory capacity expansion method of the switch comprises the following steps:
step S1: and configuring a memory to be used and a standby memory for the switch in advance.
Specifically, on one hand, the method configures a memory to be used for the switch in advance for the switch to use when the switch works; on the other hand, the method and the device configure the standby memory for the switch in advance for capacity expansion when the capacity of the memory to be used is insufficient.
It can be understood that, in the present application, a spare memory with a relatively sufficient capacity needs to be configured for the switch, so as to successfully expand the capacity in the following.
Step S2: and acquiring the capacity use condition of the memory to be used.
Specifically, according to the method and the device, after the to-be-used memory is started, the capacity of the to-be-used memory is automatically and circularly detected, the used capacity and the remaining available capacity of the to-be-used memory can be known, and therefore the capacity use condition of the to-be-used memory is obtained, and a basis is provided for subsequently judging whether the capacity of the to-be-used memory needs to be expanded or not.
Step S3: automatically judging whether the memory to be used needs to be expanded according to the capacity use condition; if yes, go to step S4.
Specifically, the capacity usage condition of the to-be-used memory can show whether the remaining available capacity of the to-be-used memory is sufficient, and it can be understood that when the remaining available capacity of the to-be-used memory is insufficient, the to-be-used memory needs to be expanded, so that the application can automatically judge whether the to-be-used memory needs to be expanded according to the capacity usage condition of the to-be-used memory, and if the to-be-used memory needs to be expanded, the capacity expansion operation of the to-be-used memory is executed; if the to-be-used memory does not need to be expanded, the expansion operation of the to-be-used memory does not need to be executed.
Step S4: and automatically determining the capacity to be expanded of the memory to be used according to a preset expansion strategy, and automatically planning the memory with the same size as the capacity to be expanded from the standby memory to be used as the expansion capacity of the memory to be used.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Specifically, the expansion principle of the memory to be used specifically is as follows: the method comprises the steps of setting a capacity expansion strategy for acquiring the capacity to be expanded of the memory to be used in advance, when the capacity to be expanded of the memory to be used needs to be expanded, automatically determining the capacity to be expanded of the memory to be used according to the preset capacity expansion strategy, and then automatically planning the memory with the same size as the capacity to be expanded of the memory to be used from the standby memory.
The invention provides a memory capacity expansion method of a switch, which is characterized in that a memory to be used and a standby memory are configured for the switch in advance; acquiring the capacity use condition of a memory to be used; automatically judging whether the memory to be used needs to be expanded according to the capacity use condition; if yes, automatically determining the capacity to be expanded of the memory to be used according to a preset expansion strategy, and automatically planning the memory with the same size as the capacity to be expanded from the standby memory to be used as the expansion capacity of the memory to be used. It can be seen that, this application can carry out the dilatation to the usable memory capacity of switch automatically when the usable memory capacity of switch is not enough, need not user manual operation to user's use experience has been promoted.
On the basis of the above-described embodiment:
as an optional embodiment, the process of obtaining the capacity usage of the memory to be used includes:
after the memory to be used is started, starting the cyclic detection of the capacity of the memory to be used to obtain the capacity use condition of the memory to be used;
dynamically adjusting the cycle detection time of the capacity of the memory to be used according to the capacity use change condition of the memory to be used so as to detect the capacity of the memory to be used according to the cycle detection time after the latest adjustment; wherein, the faster the capacity of the memory to be used is used, the shorter the cycle detection time.
Specifically, after the to-be-used memory is started, the automatic cycle detection of the capacity of the to-be-used memory is started so as to obtain the capacity use condition of the to-be-used memory. It can be understood that, if the capacity of the to-be-used memory is used slowly, the present application does not need to scan and detect the capacity of the to-be-used memory once every short time, the power consumption is large, and only when the capacity of the to-be-used memory is used quickly, the capacity of the to-be-used memory needs to be scanned and detected once every short time, and the shortage of the capacity of the to-be-used memory is known.
Based on the above, the method dynamically adjusts the cycle detection time of the capacity of the memory to be used according to the capacity use change condition of the memory to be used, specifically, when the capacity use of the memory to be used is slowed down, the cycle detection time of the capacity of the memory to be used is prolonged, so that the purpose is to scan and detect the capacity of the memory to be used once at a longer time interval; when the capacity of the memory to be used is used more quickly, the cyclic detection time of the capacity of the memory to be used is shortened, and the purpose is to scan and detect the capacity of the memory to be used once at shorter time intervals.
As an optional embodiment, acquiring a capacity use condition of a memory to be used; the process of automatically judging whether the memory to be used needs capacity expansion according to the capacity use condition comprises the following steps:
acquiring the used capacity of a memory to be used;
calculating the proportion of the used capacity of the memory to be used to the current total capacity of the memory to be used; the current total capacity of the to-be-used memory is equal to the used capacity of the to-be-used memory plus the current remaining available capacity of the to-be-used memory;
judging whether the proportion exceeds a preset proportion threshold value or not;
if yes, determining that the memory to be used needs to be expanded;
if not, determining that the memory to be used does not need to be expanded.
Specifically, the capacity use condition of the memory to be used is obtained, specifically, the used capacity of the memory to be used is obtained (cycle detection time dynamic adjustment), and the used capacity of the memory to be used is divided by the current total capacity of the memory to be used, so that the proportion of the used capacity of the memory to be used to the current total capacity of the memory to be used is obtained, and the capacity use condition of the memory to be used is reflected by the proportion of the used capacity of the memory to be used to the current total capacity of the memory to be used.
It can be understood that, the higher the proportion of the used capacity of the memory to be used to the current total capacity of the memory to be used is, the lower the current remaining available capacity of the memory to be used is, and when the current remaining available capacity of the memory to be used is insufficient, the capacity of the memory to be used needs to be expanded, so the application sets a proportion threshold in advance, and considers that: when the proportion of the used capacity of the to-be-used memory to the current total capacity of the to-be-used memory exceeds a preset proportion threshold, the current residual available capacity of the to-be-used memory is too small, and the capacity expansion of the to-be-used memory is necessary; when the proportion of the used capacity of the memory to be used to the current total capacity of the memory to be used does not exceed the preset proportion threshold, the current remaining available capacity of the memory to be used is enough to be used, and the capacity expansion of the memory to be used is not needed.
Based on this, after obtaining the proportion of the used capacity of the memory to be used to the current total capacity of the memory to be used, the method compares the proportion value with a preset proportion threshold value, and if the proportion value exceeds the preset proportion threshold value, the memory to be used is determined to need capacity expansion; and if the proportion value does not exceed the preset proportion threshold value, determining that the capacity of the memory to be used does not need to be expanded.
As an alternative embodiment, the process of obtaining the current total capacity of the to-be-used memory includes:
determining the initial total capacity of the memory to be used in advance according to the initial configuration condition of the memory to be used, and taking the initial total capacity as the current total capacity of the memory to be used;
after the memory with the same size as the capacity to be expanded is automatically planned from the standby memory to be used as the expanded capacity of the memory to be used, the current total capacity of the memory to be used is added with the capacity to be expanded to obtain the current updated total capacity of the memory to be used.
Specifically, after the capacity of the memory to be used is expanded, the total capacity of the memory to be used (the used capacity of the memory to be used + the remaining available capacity of the memory to be used) changes, and it can be understood that, when the ratio of the used capacity of the memory to be used to the current total capacity of the memory to be used is obtained, the current total capacity of the memory to be used needs to be updated according to an actual situation, so as to obtain a real ratio of the used capacity of the memory to be used to the current total capacity of the memory to be used.
Based on this, the initial total capacity of the memory to be used is determined in advance according to the initial configuration condition of the memory to be used, that is, when the memory to be used is not expanded, the initial total capacity of the memory to be used is the current total capacity of the memory to be used. After the memory with the same size as the capacity to be expanded is automatically planned from the standby memory to be used as the expanded capacity of the memory to be used, the current total capacity of the memory to be used plus the capacity to be expanded is the current total capacity of the memory to be used, and if the memory with the same size as the capacity to be expanded is automatically planned from the standby memory to be used as the expanded capacity of the memory to be used subsequently, the current total capacity of the memory to be used is the current total capacity of the memory to be used plus the capacity to be expanded, so that the current updated total capacity of the memory to be used is obtained.
As an optional embodiment, the process of automatically determining the capacity to be expanded of the memory to be used according to the preset expansion policy includes:
predicting the pre-used memory capacity of the switch in a certain period of time in the future according to the historical capacity use condition of the memory to be used;
and taking the capacity of the pre-used memory as the capacity to be expanded of the memory to be used.
Specifically, considering that the traffic flow corresponding to some switches is large and the capacity of the to-be-used memory corresponding to the switches is used more, when the to-be-used memories corresponding to the switches are expanded, the capacity of the memories is expanded as much as possible, so as to avoid frequent expansion of the to-be-used memories. Based on this, according to the historical capacity use condition of the to-be-used memory, the pre-used memory capacity of the switch in a certain period of time in the future, namely the to-be-expanded capacity of the to-be-used memory, can be predicted, specifically, the more capacity use in the past certain period of time exists in the to-be-used memory, the greater the capacity requirement of the switch in the certain period of time in the future is considered, namely, the greater the to-be-expanded capacity of the to-be-used memory is, and therefore the capacity expansion of the to-be-used memory is more reasonably performed.
As an alternative embodiment, the process of predicting the pre-used memory capacity of the switch in a certain period of time in the future according to the historical capacity usage of the memory to be used includes:
a deep learning model for predicting the pre-used memory capacity of the switch in a certain period of time in the future according to the historical capacity use condition of the memory to be used is established and trained in advance;
after the historical capacity use condition of the memory to be used is obtained, the historical capacity use condition of the memory to be used is input into the deep learning model, and the pre-used memory capacity of the switch in a certain period of time in the future is obtained.
Specifically, the method can predict the pre-used memory capacity of the switch within a certain time period in the future by adopting a deep learning algorithm, specifically, a deep learning model which is established in advance and trained and used for predicting the pre-used memory capacity of the switch within the certain time period in the future according to the historical capacity use condition of the memory to be used is established and trained, the historical capacity use condition of the memory to be used is used as the input of the deep learning model, and the output of the deep learning model is the pre-used memory capacity of the switch within the certain time period in the future.
It can be understood that, when the historical capacity usage of the to-be-used memory changes, the predicted pre-used memory capacity of the switch in a certain period of time in the future also changes, so that the dynamic adjustment of the to-be-expanded capacity of the to-be-used memory is realized.
