Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for detecting a memory.
Background
The distributed system is a multi-device architecture interconnected by communication networks, and tasks are executed by coordinating and interacting among devices. In a distributed communication system, a heartbeat mechanism can be utilized to perform reliability detection between devices. The heartbeat mechanism is a mechanism for regularly sending a self-defined structural body, such as a heartbeat message, between the devices to inform the other party of the current working state of the other party so as to ensure the effective connection between the devices. When the abnormality of the opposite device is detected, the abnormal device is repaired, such as device switching operation.
The sending and receiving of the heartbeat message by the device depends on the operation of an operating system in the device, such as the operation of a Central Processing Unit (CPU) and/or a memory resource. In the distributed system, the CPU of the first device processes the X service, other services, such as the A service and the B service, are cached in the memory, and the CPU can process the A service and the B service in sequence only after the X service is processed and the CPU is released. In order to avoid losing the data packets, the service a and the service B need to cache the data packets to be processed in their own cache queues, and the cached data packets need to apply for occupying the memory.
If the CPU has a long time to process the X service and the memory is occupied by the cache messages of the a service and the B service, the heartbeat message between the devices cannot be normally sent because there is no free memory, and after a period of time, the second device (or called opposite-end device) confirms that the first device is abnormal, thereby causing device switching.
However, the time period for the CPU to process the X service is a situation of transient memory exhaustion, and when the CPU finishes processing the X service, the transient memory exhaustion will disappear, and the memory of the first device can be recovered to normal.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without any creative effort belong to the protection scope of the present application.
The method for detecting a memory provided in the embodiment of the present invention is applied to the distributed system shown in fig. 1, where the distributed system includes a plurality of first devices and a second device (or "standby device") corresponding to each of the first devices. The first device and the second device may be servers or terminals, and in order to ensure the accuracy of detection, the servers may be application servers or cloud servers with strong computing power; a terminal may be a User Equipment (UE) with high computing power, a handheld device with wireless communication capabilities, a vehicle mounted device, a wearable device, a computing device or other processing device connected to a wireless modem, a Mobile Station (MS), etc.
The first device is used for processing the current service and caching the service to be processed.
First, the first device and the second device need to establish a communication connection, and after the communication connection is established, the first device may send service information to the second device, where the service information may include a memory space size of a current service.
The first device and the second device monitor the running state of the other device through heartbeat detection. Fig. 2 shows a schematic diagram of a heartbeat detection principle, and as shown in fig. 2, a first device starts a self-configured Timer (Timer), and sends a heartbeat message to a second device when a timing period of the Timer arrives. After receiving the heartbeat message from the first device, the second device updates a heartbeat count (counter) of the first device, and if the second device does not receive the heartbeat message of the first device within a first preset time period, the second device determines that the first device is abnormal, and executes corresponding fault processing, namely, switches to the second device to process the current service.
Correspondingly, the second device may also start a self-configured Timer (Timer), and send the heartbeat packet to the first device when a timing period of the Timer comes. After receiving the heartbeat message from the second device, the first device updates a heartbeat count (counter) of the second device, and if the first device does not receive the heartbeat message of the second device within a first preset time period, the first device determines that the second device is abnormal, and executes corresponding fault processing, such as generating alarm information and/or restarting the second device.
In the prior art, when there is no idle resource in the memory of the first device, the second device does not receive the heartbeat packet of the first device in the first preset time period, and the second device directly considers that the first device is abnormal, and performs the device switching operation, thereby causing packet loss in the switching process.
The system of the embodiment of the invention executes the step A: if the second memory area is judged and known to have no free resources, a heartbeat message is sent to the second equipment through the memory space of the first memory area, and the first memory area comprises the message occupation space of a preset number of heartbeat messages; and B: comparing the current memory space of the second memory area with a preset back-up threshold, wherein the current memory space which is compared for the first time is the initial memory space of the second memory area; when the current memory space of the second memory area is not smaller than the preset back-up threshold, determining that the second memory area is in transient abnormity before the current moment; and B, when the current memory space of the second memory area is smaller than the preset back-up threshold value, returning to execute the step A. The method reduces the equipment switching frequency caused by the fact that the heartbeat message cannot be sent after the whole memory is filled with the service to be processed in the prior art, namely reduces the switching times among the equipment, reduces the packet loss rate and improves the accuracy of heartbeat detection.
It should be noted that the second device in the system may also perform the above operations, and the embodiment of the present invention is not described herein again.
The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
Fig. 3 is a flowchart illustrating a method for detecting a memory according to an embodiment of the present invention. As shown in fig. 3, in a first device including a first memory area and a second memory area, the method may include:
step 310, based on the memory occupation ratio of the current traffic, a first memory area and a second memory area are created.
Before executing the step, the first device establishes a communication connection, such as a TCP communication connection, with the second device, and sends service information to the second device, where the service information may include information such as a current traffic volume, a first device identifier, and an MAC address, and the current traffic volume includes a traffic volume of a currently running service and a traffic volume of a service to be processed.
The first device creates a first memory area and a second memory area based on the memory occupation ratio of the current traffic.
The second memory area is used for caching the current operation service and the service to be processed, and caching the heartbeat message to be sent when the idle resource exists. The first memory area is used for caching heartbeat messages to be sent when no idle resources exist in the second memory area, the first memory area comprises a preset number of message occupation spaces of the heartbeat messages, and the message occupation spaces are memory spaces occupied by the heartbeat messages.
In an optional implementation manner, a cache queue of heartbeat messages is created in the first memory area, the number of the heartbeat messages in the cache queue is determined by the memory space of the first memory area and the size of each heartbeat message, and the sending interval between adjacent heartbeat messages is a second preset time period, that is, the buffering time of the cache queue is a product of the second preset time period and the number of the heartbeat messages, it can be understood that the buffering time is a preset time period for prolonging an abnormal phenomenon, and the abnormal phenomenon is a condition that no idle resource exists in the second memory area.
For example, the memory space is 20M, the size of each heartbeat packet is 1M (the size of the heartbeat packet is only stated as an example), the number of the heartbeat packets in the buffer queue is 20, and if the transmission interval between adjacent heartbeat packets in the buffer queue is 6s, the buffer time available in the buffer queue is 2 min.
Optionally, the second memory area may include a memory space occupied by the service memory and a message memory space occupied by the heartbeat message, and if the memory space occupied by the service memory is 100M and the message memory space occupied by the heartbeat message is 30M, the second memory area is 130M in total.
Step 320, if it is determined that there is no idle resource in the second memory area, sending a heartbeat message to the second device through the first memory area.
And under the condition that the second memory area has idle resources, the first equipment sends a heartbeat message to the second equipment through the second memory area. Under the condition that no idle resource exists in the second memory area, the first device sends a heartbeat message to the second device through the first memory area and releases the message occupation space of the heartbeat message, and the first device receives the heartbeat message sent by the second device through the second memory area, so that the message occupation space of the received heartbeat message is not increased in the first memory area, that is to say, under the condition, the message occupation space of the first memory area is released along with the sending of each heartbeat message.
If the first device receives the heartbeat message sent by the second device in the first preset time period through the second memory area, the memory space of the second memory area increases the message occupation space of the heartbeat message, and the memory space of the first memory area does not increase the message occupation space of the heartbeat message.
If the first device does not receive the heartbeat message sent by the second device in the first preset time period through the second memory area, the memory space of the second memory area and the memory space of the first memory area do not increase the message occupation space of the heartbeat message.
In one example, in the case that there are free resources in the second memory area, the initial memory space of the first memory area is 20M, the current memory space is 20M, the initial memory space of the second memory area is 30M, and the current memory space is 28M. The first device sends 1M heartbeat messages to the second device through the first memory area, and the memory space of the first memory area becomes 19M. If a heartbeat message of 1M sent by the second device is received in the first preset time period, the memory space of the first memory area is kept at 19M, and the memory space of the second memory area is changed into 29M. If the heartbeat message of 1M sent by the second device is not received within the first preset time period, the memory space of the first memory area is kept 19M, and the memory space of the second memory area is still kept 28M.
Step 330, comparing the current memory space of the second memory area with a preset back-up threshold value, and determining whether the second memory area is in transient abnormality before the current time.
The first device may compare the current memory space of the second memory area with a preset back-up threshold in real time, where the preset back-up threshold is a minimum memory value for the second memory area to back-up the occupied space of the message released by the first memory area. The current memory space to be compared for the first time is the initial memory space of the second memory area, and the preset back-up threshold value can be determined according to the memory occupation proportion of the current running service, and can also be a fixed value set according to a service processed by the first device for a long time.
In an embodiment, when the first device detects that the current memory space of the second memory area is not less than the preset back-up threshold, it is determined that the second memory area is in a transient abnormality before the current time, where the current time is the time when the current memory space of the second memory area is not less than the preset back-up threshold.
Further, if it is determined that the current memory space of the first memory area is smaller than the initial memory space, that is, the first memory area releases the message occupation space, when the current memory space of the second memory area is not smaller than the preset back-up threshold, the message occupation space released in the first memory area may be back-up based on the current memory space of the second memory area, and the current memory space of the second memory area is updated, that is, the memory space of the second memory area after performing back-up is the new current memory space.
And if the second memory area after the back compensation is executed has idle resources, sending a heartbeat message to the second equipment through the new current memory space in the second memory area. If there is no free resource in the second memory area after performing the compensation, the process returns to step 320.
It can be understood that, if it is determined that the current memory space of the first memory area is equal to the initial memory space, that is, the message occupied space is not released by the first memory area, the back compensation of the message occupied space is not performed.
For example, the initial memory space of the second memory area is 30M, the predetermined complementary threshold of the second memory area is 25M, and the initial memory space of the first memory area is 20M.
After a time period T, the second memory area caches a large amount of services to be processed, at this time, the first device detects that the current memory space of the second memory area is 0M, that is, no free resources exist in the second memory area, then the first memory area is used to send heartbeat messages to the second device, after two heartbeat messages are released in the first memory area, for example, 2M message occupation space is released, at this time, the first device detects that the current memory space of the second memory area is 28M (that is, the current memory space of the second memory area is changed from 0M to 28M), since 28 is greater than 25, it is determined that the second memory area is in transient anomaly before the current time, and in the case that the current memory space of the second memory area is greater than 25M, the current 28M memory space of the second memory area is used to complement the 2M message occupation space released in the first memory area, and after the complementation, the new current memory space of the first memory area is 20M, the new current memory space of the second memory area is 26M, and then because the second memory area has idle resources, the heartbeat message is sent to the second device through the new current memory space of the second memory area.
In an embodiment, when the current memory space of the second memory area is smaller than the predetermined complementary threshold and there is no free resource, the step 320 is executed again.
And B, when the number of times of executing the step A is smaller than the preset number of the center jump messages in the first memory area, detecting that the current memory space of the second memory area is not smaller than a preset back-up threshold value, and determining that the second memory area is in transient abnormity before being compared with the preset back-up threshold value.
If the number of times of returning to execute step 320 is equal to the preset number of the heartbeat messages in the first memory area, it is determined that the second memory area is in permanent abnormality.
For example, the memory space of the first memory area includes a message occupation space of 20 heartbeat messages, that is, the first memory area may send out 20 heartbeat messages. When no free resource exists in the second memory area, after the first memory area continuously sends 10 heartbeat messages, the service volume cached in the second memory area is reduced, so that the second memory area has the free resource, at the moment, the current memory space of the second memory area is larger than the preset back-up threshold value, the memory space of the first memory area can be back-up, and at the moment, the second memory area is determined to be in transient abnormity before the moment when the current memory space of the second memory area is compared to be larger than the preset back-up threshold value.
However, when the second memory area does not have the free resources, and after the first memory area has continuously sent 20 heartbeat messages, the traffic cached in the second memory area is not changed, that is, the second memory area still does not have the free resources, at this time, the current memory space of the second memory area is smaller than the preset back-supplementing threshold value, the memory space of the first memory area cannot be back-supplemented, and at this time, it is determined that the second memory area is in a permanent abnormality.
Optionally, after determining that the second memory area is in the permanent exception, the first device may generate alarm information, where the alarm information is used to indicate that the second memory area of the first device is in the permanent exception, and the alarm information may be recorded in log information.
Optionally, after it is determined that the second memory area is in a permanent abnormality, because the first device cannot send the heartbeat message to the second device, after a first preset time period, the first device receives a switching instruction sent by the second device, where the switching instruction is used to instruct to switch to the second device to process the current service and the service to be processed.
Or after determining that the second memory area is in permanent exception, the first device may start a device switching operation, and switch to the second device to process the current service and the service to be processed.
The method executes step a: if the second memory area is judged and known to have no free resources, a heartbeat message is sent to the second equipment through the memory space of the first memory area, and the first memory area comprises the message occupation space of a preset number of heartbeat messages; and B: comparing the current memory space of the second memory area with a preset back-up threshold, wherein the current memory space which is compared for the first time is the initial memory space of the second memory area; when the current memory space of the second memory area is not smaller than the preset back-up threshold, determining that the second memory area is in transient abnormity before the current moment; and B, when the current memory space of the second memory area is smaller than the preset back-up threshold value, returning to execute the step A. According to the method, the whole memory is divided into the second memory area and the first memory area which sends the heartbeat message when no idle resource exists in the second memory area, so that the equipment switching frequency caused by the fact that the whole memory cannot send the heartbeat message after being occupied by the service to be processed in the prior art is reduced, namely the switching frequency among equipment is reduced, the packet loss rate is reduced, and the accuracy of heartbeat detection is improved.
Corresponding to the above method, an embodiment of the present invention further provides a detection apparatus, as shown in fig. 4, where the detection apparatus includes: a transmitting unit 410, a comparing unit 420 and a determining unit 430;
