It does not repeat them here.
Preferred embodiment of the present application is illustrated below in conjunction with Figure of description, it should be understood that described herein
Preferred embodiment only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention, and in the absence of conflict, this Shen
Please in embodiment and embodiment in feature can be combined with each other.
Fig. 3 is a kind of flow diagram of the detection method of memory provided in an embodiment of the present invention.As shown in figure 3, using
In the first equipment, the first equipment includes the first memory field and the second memory field, this method may include:
Step 310, the EMS memory occupation ratio based on current traffic create the first memory field and the second memory field.
Before executing the step, the first equipment and the second equipment are established and are communicated to connect, and if TCP communication connects, first is set
Standby to send business information to the second equipment, business information may include current traffic, the first device identification, such as MAC Address
Information, current traffic include the portfolio of current operation business and the portfolio of business to be processed.
EMS memory occupation ratio of first equipment based on current traffic creates the first memory field and the second memory field.
Second memory field for caching current operation business, business to be processed, and when there are idling-resource caching to
The heartbeat message of transmission.First memory field is used to cache heartbeat report to be sent when idling-resource is not present in the second memory field
Text, the first memory field include the message occupied space of preset quantity heartbeat message, and message occupied space is heartbeat message occupancy
Memory headroom.
In a kind of optional implementation, the buffer queue of heartbeat message is created in the first memory field, in buffer queue
The number of heartbeat message determines by the memory headroom of the first memory field and the size of each heartbeat message, and between adjacent cardiac message
Transmission between be divided into the second preset period of time, that is to say, that the buffer time of the buffer queue is the second preset period of time and heartbeat report
The product of literary number, it is to be understood that buffer time is the preset extension time to abnormal phenomenon, abnormal phenomenon second
The case where idling-resource is not present in memory field.
For example, memory headroom is 20M, the size of each heartbeat message is that (size of heartbeat message is only used as example to 1M herein
Son is stated), the number of heartbeat message is 20 in buffer queue, if between the transmission in buffer queue between adjacent cardiac message
It is divided into 6s, then buffer queue available buffer time is 2min.
Optionally, the second memory field may include that the memory headroom of business EMS memory occupation and the message memory of heartbeat message account for
With space, such as memory headroom of business EMS memory occupation is 100M, and the message memory footprint of heartbeat message is 30M, then second
The total 130M in memory field.
If step 320, judgement know that there is no idling-resources for the second memory field, pass through the first memory field to the second equipment
Send a heartbeat message.
In the second memory field there are in the case where idling-resource, the first equipment is sent by the second memory field to the second equipment
Heartbeat message.In the case where idling-resource is not present in the second memory field, the first equipment passes through the first memory field to the second equipment
Heartbeat message is sent, and discharges the message occupied space of the heartbeat message, the first equipment receives second by the second memory field and sets
The heartbeat message that preparation is come, therefore the first memory field does not increase the message occupied space of the received heartbeat message, that is to say, that
In this case, the message occupied space of the first memory field is discharged with the sending of each heartbeat message.
If the first equipment receives the heartbeat message that the second equipment is sent by the second memory field in the first preset period of time,
Then the memory headroom of the second memory field increases the message occupied space of the heartbeat message, and the memory headroom of the first memory field does not increase
The message occupied space of the heartbeat message.
If the first equipment does not receive the heartbeat report that the second equipment is sent by the second memory field in the first preset period of time
Text, the then message that the memory headroom of the memory headroom of the second memory field and the first memory field does not increase the heartbeat message occupy empty
Between.
In one example, in the second memory field there are in the case where idling-resource, the initial memory of the first memory field is empty
Between be 20M, current memory space 20M, the initial memory space of the second memory field is 30M, current memory space 28M.The
One equipment sends the heartbeat message of 1M by the first memory field to the second equipment, and the memory headroom of the first memory field becomes 19M.If
The heartbeat message for the 1M that the second equipment is sent is received in the first preset period of time, the memory headroom of the first memory field keeps 19M,
The memory headroom of second memory field becomes 29M.If not receiving the heartbeat for the 1M that the second equipment is sent in the first preset period of time
Message, the memory headroom of the first memory field keeps 19M at this time, and the memory headroom of the second memory field still keeps 28M.
Step 330 is compared the current memory space of the second memory field with default covering threshold value, determines in second
Area is deposited before current time whether in of short duration exception.
First equipment the current memory space to the second memory field can be compared with default covering threshold value in real time, be preset
Covering threshold value is the minimum memory value that the second memory field covers the message occupied space that the first memory field discharges.Wherein,
The current memory space being compared for the first time is the initial memory space of the second memory field, and presetting covering threshold value can be according to current
The EMS memory occupation ratio-dependent of operation business, the fixed value that can also be arranged according to the business of the first equipment long-term disposal.
In one embodiment, when the first equipment detects the current memory space of the second memory field not less than default covering
When threshold value, determine that the second memory field is in of short duration exception before current time, current time is to compare the second memory field
At the time of current memory space is not less than default covering threshold value.
Further, however, it is determined that the current memory space of the first memory field is less than initial memory space, i.e. the first memory field
Message occupied space is released, then when the current memory space in the second memory field is not less than default covering threshold value, is based on second
The current memory space of memory field can cover the message occupied space discharged in the first memory field, and update second
The current memory space of memory field, that is, the memory headroom for executing the second memory field after covering is new current memory space.
If executing the second memory field after covering, there are idling-resources, empty by current memory new in the second memory field
Between to the second equipment send heartbeat message.If executing the second memory field after covering is not present idling-resource, returns and execute step
Rapid 320.
It is understood that if it is determined that the current memory space of the first memory field is equal to initial memory space, i.e., in first
It deposits area and does not discharge message occupied space, then do not execute the covering of message occupied space.
For example, the initial memory space of the second memory field is 30M, the default covering threshold value of the second memory field is 25M, first
The initial memory space of memory field is 20M.
After period T, the second memory field has cached a large amount of business to be processed, and the first equipment detects second at this time
The current memory space of memory field is 0M, i.e. idling-resource is not present in the second memory field, uses the first memory field to second later
Equipment sends heartbeat message and such as releases the message occupied space of 2M after the first memory field releases two heartbeat messages, this
When the first equipment detect that the current memory space of the second memory field is that (i.e. the current memory space of the second memory field is from 0M by 28M
Become 28M), since 28 greater than 25, therefore determine that the second memory field is in of short duration exception before current time, and in the second memory
In the case that the current memory space in area is greater than 25M, the first memory field is released using the current 28M memory headroom of the second memory field
The 2M message occupied space put is covered, and after covering, the new current memory space of the first memory field is 20M, the second memory
The new current memory space in area is 26M, later since there are idling-resources for the second memory field, therefore passes through the new of the second memory field
Current memory space to the second equipment send heartbeat message.
In one embodiment, covering threshold value is preset when the current memory space of the second memory field is less than, and there is no skies
When not busy resource, 320 are returned to step.
When the number for returning to step A jumps the preset quantity of message less than the first memory district center, second is detected
The current memory space of memory field is not less than default covering threshold value, it is determined that is presetting covering threshold value comparison with this in the second memory field
It is in of short duration exception before.
If the number for returning to step 320 is equal to the preset quantity that the first memory district center jumps message, it is determined that second
Memory field is in permanent abnormal.
For example, the memory headroom of the first memory field includes the message occupied space of 20 heartbeat messages, i.e. the first memory field
20 heartbeat messages can be issued.When idling-resource is not present in the second memory field, the first memory field has continuously sent out 10 hearts
After jumping message, the portfolio of the second memory field caching tails off, make the second memory field there are idling-resource, at this time the second memory field
Current memory space is greater than default covering threshold value, can cover to the memory headroom of the first memory field, determine second at this time
Memory field is in of short duration exception before at the time of the current memory space for comparing the second memory field is greater than default covering threshold value.
But when idling-resource is not present in the second memory field, and the first memory field has continuously sent out 20 heartbeat messages
Afterwards, the portfolio of the second memory field caching is constant, i.e., idling-resource is still not present in the second memory field, at this time second memory field
Current memory space is less than default covering threshold value, it is not possible to cover to the memory headroom of the first memory field, determine the at this time
Two memory fields are in permanent abnormal.
Optionally it is determined that the second memory field is in after permanent exception, warning information, alarm letter is can be generated in the first equipment
The second memory field that breath is used to indicate the first equipment is in permanent abnormal, which can recorde in log information.
Optionally it is determined that the second memory field is in after permanent exception, since the first equipment is sent without the second equipment of normal direction
Heartbeat message, therefore after the first preset period of time, the first equipment receives the switching command that the second equipment is sent, and switching command is for referring to
Show and switches to the second equipment processing current business and business to be processed.
Alternatively, the first equipment can star equipment handover operation, cut after determining that the second memory field is in permanent exception
Shift to the second equipment processing current business and business to be processed.
This method executes step A: if judgement knows that there is no idling-resources for the second memory field, pass through the first memory field
Memory headroom sends a heartbeat message to the second equipment, and the first memory field includes that the message of preset quantity heartbeat message occupies
Space；Step B: the current memory space of the second memory field is compared with default covering threshold value, wherein be compared for the first time
Current memory space be the second memory field initial memory space；When the current memory space of the second memory field is no more than default
When covering threshold value, determine the second memory field before current time in of short duration exception；When the current memory of the second memory field is empty
Between when being less than default covering threshold value, return to step A.This method is by marking off the second memory field for overall memory and
Two memory fields be not present idling-resource when send heartbeat message the first memory field, reduce in the prior art overall memory by
Processing business can not send equipment switching frequency caused by heartbeat message after taking, that is, reduce the switching times of equipment room,
Packet loss is reduced, the accuracy of heartbeat detection is improved.
Corresponding with the above method, the embodiment of the present invention also provides a kind of detection device, as shown in figure 4, the detection device
It include: transmission unit 410, comparing unit 420 and determination unit 430；
Transmission unit 410, if for judging to know that there is no idling-resources for the second memory field, pass through the first memory field
Memory headroom sends a heartbeat message to the second equipment, and the first memory field includes that the message of preset quantity heartbeat message occupies
Space；
Comparing unit 420 is compared for the current memory space to the second memory field with default covering threshold value,
In, the current memory space being compared for the first time is the initial memory space of the second memory field；
Determination unit 430, for when the current memory space of the second memory field is not less than default covering threshold value, determining the
Two memory fields are in of short duration exception before current time；
When the current memory space of the second memory field is less than default covering threshold value, transmission unit 420 is triggered；
Wherein, the second memory field is used to cache current operation business and business to be processed, and when there are idling-resource
Cache heartbeat message to be sent.
In an optional realization, which further includes releasing unit 440 and covering unit 450；
Releasing unit 440, for sending a heartbeat message to the second equipment by the first memory field in transmission unit 410
Later, the message occupied space of heartbeat message described in the first memory field is discharged.
Unit 450 is covered, for when the current memory space of the second memory field is not less than default covering threshold value, based on the
