A kind of flow diagram, it may include step S201- that this method, which can be applied to the first network equipment in polymerization unit,
S203。
S201 is set in each time window in continuous n time window by link to be detected and the second network
It is standby to carry out data interaction.
Wherein, n is positive integer more than or equal to 2, link to be detected belong to first network equipment and second network equipment it
Between multiple redundant links in one or more links.Continuous n time window, can refer to that this n time window exists
Be in time domain it is adjacent, the length of each time window can according to actual needs or user experience is configured.Assuming that every
The when a length of 10S (second) of a time window, and the start time point of first time window is t=0S, for convenience of description with
[t1, t2] indicates a time window, and wherein t1 indicates the initial time of the time window, and t2 indicates the end of the time window
Time, then n time window can be respectively [0,10], [10,20] ..., [10 (n-1), 10n].

Preset times threshold value can be 2.If first network equipment and second network equipment successfully carry out in each time window
Data interaction, then first network equipment and second network equipment are in this n time window, the success of the data interaction carried out
Number is 3.
If should be noted that preset times threshold value is greater than n, even if first network equipment and second network equipment exist
Data interaction is successfully carried out in each time window, number of success is still less than preset times threshold value, therefore, in order to ensure that rationally
Property, in the present embodiment, preset times threshold value is less than or equal to n.
S203, if number of success is not less than preset times threshold value, determining link to be detected, there is no failures.
If first network equipment and second network equipment successfully carry out data interaction in a time window, then may be used
To think in the time window, link to be detected be can work normally, it can carry out control message by link to be detected

In case where the port of link to be detected is in physical state up, protocol status down.If according to port
Physical state judgement, then the link to be detected may be determined as to the link there is no failure, this and the obvious phase of actual conditions
Instead.And the embodiment is selected, since first network equipment is carrying out data friendship by the link to be detected and second network equipment
It is mutually to be difficult to (or even can not) successfully, therefore number of success can largely be less than preset times threshold value, then may be used at this time
To determine the link to be detected, there are failures, it is seen that result is more accurate.
Another flow diagram of chain circuit detecting method provided in an embodiment of the present invention is shown referring to Fig. 3, Fig. 3, it should
Method can be applied to the first network equipment in polymerization unit, may include step S301-S304.

The step is identical as S201, may refer to the description previously with regard to S201, details are not described herein.
S302 determines first network equipment and second network equipment in n time window, the data interaction carried out
Whether number of success is less than preset times threshold value, if number of success is not less than preset times threshold value, executes S303, if success
Number is less than preset times threshold value, executes S304.
The step is identical as S202, may refer to the description previously with regard to S202, details are not described herein.
S303, determining link to be detected, there is no failures.
The step is identical as S203, may refer to exist previously with regard to the description of S203, details are not described herein.
S304 determines that there are failures for link to be detected, and link to be detected and second network equipment is stopped using to be counted
According to interaction.
In one embodiment, first network equipment can record link to be detected in running log there are failures.It can be with
Understand, if number of success be less than preset times threshold value, it may be considered that if first network equipment continue to use this to
Detection link and second network equipment carry out the interaction of control message, then probably due to link failure problem, causes to control message
It is lost during interaction, in turn results in polymerization unit division.Therefore first network equipment can stop using this to be detected
Link and second network equipment carry out control message interaction.
In one embodiment, the first network equipment and second network equipment carry out the mode of data interaction, can be to the
Two network equipments send probe messages, and receive the response message of second network equipment feedback, can carry in response message
The format of the number (hereinafter referred to as receive number) for the probe messages that second network equipment has been received, response message can be such as figure
Shown in 4.Wherein, IRF Head indicates that the format of heading is identical as the IRF control format of heading of message or compatible,
Local_Recv_Num is entrained receive number, and Tail indicates the message trailer of message.In an alternative embodiment, it visits
Observe and predict the quantity that the response message that first network equipment has been received can also be carried in text, and the message of probe messages
Format can be identical with the message format of response message.
Probe messages are sent to second network equipment with first network equipment below, and receive second network equipment feedback
For response message, chain circuit detecting method provided in an embodiment of the present invention is illustrated, may include step referring to Fig. 5
S501-S504
S501, in each time window in continuous n time window, first network equipment passes through link to be detected
Probe messages are sent to second network equipment.
In each time window, according to actual needs, first network equipment can send one to second network equipment
Probe messages can also send multiple probe messages to second network equipment.
S502, in each time window in the n time window, second network equipment is receiving first network hair
After the probe messages sent, response message is sent to first network equipment.
Wherein, receive number is carried in response message.Further, second network equipment can be one in local maintenance
The variable is denoted as Local_Probe_Num for convenience of discussing, the spy having been received for recording second network equipment by variable
Observe and predict the number of text.
Before starting to execute S501, Local_Probe_Num is initialized as 0, whenever connecing in a time window
After the probe messages for receiving the transmission of first network equipment, Local_Probe_Num is enabled to add 1 certainly.Such as assume Local_Probe_
Num=0, in first time window, after second network equipment receives first probe messages of first network equipment transmission,
It enables
Local_Probe_Num=Local_Probe_Num+1=1.
After second network equipment receives second probe messages that first network equipment is sent later, enable
Local_Probe_Num=Local_Probe_Num+1=2.
Similarly first network equipment can also be in such a variable of local maintenance, for having recorded first network equipment
The number of the response message received.
S503, the reception that first network equipment carries the response message that the last one is received in the n time window
Smaller value in number, and received response message total degree in n time window, as first network equipment and the
Two network equipments carry out the number of success of data interaction in n time window.
In embodiment, which can be denoted as in one variable of local maintenance for convenience of discussing by first network equipment
Local_Recv_Num, for recording the receive number carried in the response message that first network equipment is most recently received.
For example, if in third time window, first network equipment receive second network equipment pass through it is to be detected
The response message that link is sent, and the receive number carried in the response message is 2, then enables Local_Recv_Num=2.Such as
For fruit in third time window, first network equipment is not received by the response that second network equipment is sent by link to be detected
Message then maintains the value of Local_Recv_Num constant.After n time window, the value of Local_Recv_Num is
The receive number that first network equipment the last one response message received in this n time window carries.
The receive number that the first network equipment response message that the last one is received in n time window carries, can
To indicate the number of second network equipment probe messages received in n time window, it can indicate first network
The number for the probe messages that equipment is successfully transmitted in n time window by link to be detected.And first network equipment is at n
Received response message total degree in time window, can indicate first network equipment in n time window by
The total degree for the probe messages that detection link is successfully transmitted.
Therefore, the receive number that first network equipment can be carried by the response message received, determining and the second net
Network equipment carries out the successful number of data interaction.
In one embodiment, first network equipment the last one response message received in n time window is taken
The smaller value of the receive number and first network equipment of band response message total degree received in n time window, can
The number of success of data interaction is carried out to indicate first network equipment and second network equipment in n time window.
S504, if number of success is not less than preset times threshold value, determining link to be detected, there is no failures.
In this embodiment, number of success is connecing for the last one interior response message carrying received of n time window
Number is received, and the smaller value in received probe messages total degree in n time window.And determine whether smaller value is small
In preset times threshold value, can be realized by following two mode.
The first, compare the receive number that the response message that the last one receives carries, with the institute in n time window
The size in response message total degree received, the smaller value chosen in the two are compared with preset times threshold value.
Second, it is respectively compared the receive number for the response message carrying that the last one is received and in n time window
Received response message total degree in mouthful, with the size between preset times threshold value.
If the last one response message received carry receive number and in n time window received by
Response message total degree is not less than preset times threshold value, it is determined that smaller value is not less than preset times threshold value.If last
The receive number and received response message total degree in n time window that a response message received carries are small
In preset times threshold value, it is determined that smaller value is less than preset times threshold value.
Illustratively, in an alternative embodiment, it is assumed that preset times threshold value is 2, then can be and determine the respectively
Whether the variables L ocal_Recv_Num and Local_Probe_Num that one network equipment is locally safeguarded are not less than 2.If
The variables L ocal_Recv_Num and Local_Probe_Num that first network equipment is locally safeguarded are not less than 2, it is determined that
Number of success is not less than preset times threshold value.If variables L ocal_Recv_Num that first network equipment is locally safeguarded and
Local_Probe_Num is respectively less than 2, it is determined that number of success is less than preset times threshold value.
The embodiment is selected, the receive number that first network equipment can be allowed to carry by response message obtains
The number of probe messages is received to second network equipment, and then after n time window, first network equipment can be not
In the case where needing the second network establishing to close (i.e. first network equipment can not need additionally to interact), when determining n
Between in window first network equipment and second network equipment carry out the number of success of data interaction, it is more convenient.
Below with n=3, in case where preset times threshold value is 2, in conjunction with first network equipment and second network equipment
Chain circuit detecting method provided in an embodiment of the present invention is illustrated,
In first time window: first network equipment sends a probe messages to second network equipment；
Second network equipment sends a response message, the response after receiving probe messages, to first network equipment
The receive number of carrying probe messages in message: 1.
In second time window: first network equipment sends a probe messages to second network equipment；
Second network equipment sends a response message, the response after receiving probe messages, to first network equipment
The receive number of carrying probe messages in message: 2.
In third time window: first network equipment sends a probe messages to second network equipment；
Second network equipment sends a response message, the response after receiving probe messages, to first network equipment
The receive number of carrying probe messages in message: 3.
In 4th time window: first network equipment determines reception entrained by response message that the last one is received
Number: 3 and the response message total degree that is received in first to third time window of first network equipment: 3, in the two
Smaller value whether less than 2.By judgement it is found that the smaller value in the two is greater than 2.
In the 5th time window, if smaller value is not less than 2, determining link to be detected, there is no failures；If compared with
Small value stops using link to be detected and second network equipment to carry out data interaction less than 2.By upper judgement it is found that be detected
Failure is not present in link.
It is understood that if smaller value less than 2, illustrate first network equipment and second network equipment first to
The number that data interaction is successfully carried out in third time window is smaller, it can be considered that if first network equipment continues to use
The link to be detected and second network equipment carry out data interaction, then probably due to link failure problem, causes control message to exist
It is lost in interactive process, in turn results in polymerization unit division.Therefore first network equipment can be forbidden to continue to use this to be checked
Surveyor's chain road and second network equipment carry out data interaction.
In some cases, even if failure is not present in link to be detected, first network equipment and the second network be can be realized
