Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of communication abnormality processing method, referring to Fig.1, in one embodiment, the communication abnormality processing side
Method includes：
Step S101, to the line card and master control borad in the network element device and other communication nodes in the network element device
Communications status detected；
In the present embodiment, the line card in network element device can be communicated with other line cards or master control borad, and line card is main
Complete conversion function；And master control borad can be communicated with line card, be realized to functions such as the controls, management or configuration of line card.
Wherein, the master control borad of the present embodiment is main control board.
Wherein, it when line card physics is in place, can may normally be communicated with other communication nodes, it is also possible to no
It can normally be communicated, the communication for line card and other communication nodes, the present embodiment is periodically detected；In addition,
Communication for master control borad and other communication nodes, the present embodiment are equally detected in real time.
Step S102 obtains the Exception Type of the communication abnormality when detecting communication abnormality in predetermined time period,
Accumulation process is carried out to the anomalous counts of the Exception Type；
In the present embodiment, Exception Type includes the logical of line card and other communication nodes (including other line cards and master control borad)
Letter occurs communication abnormality, master control borad and a line card and communication abnormality and master control borad and all line cards generation communication abnormality occurs
Totally three kinds.Wherein, there is a situation where communication abnormality also referred to as isolated island is abnormal for master control borad and all line cards.
In the present embodiment, it is arranged the different periods according to different Exception Types to be detected, such as default time
Section, during this period of time detects the communication of line card and other communication nodes, if detecting line card during this period of time
Communication abnormality occurs with other communication nodes, accumulation process is carried out to the anomalous counts that are abnormal, that is, calculates that this occurs altogether is different
The number of the communication abnormality of normal type, if communication abnormality occurs for line card and other a certain line cards, the line card is different before this
3 often are counted as, then the anomalous counts of the line card add 1 on the basis of 3.
Step S103 carries out the communication abnormality of corresponding anomalous counts when the anomalous counts reach preset threshold value
Processing.
In the present embodiment, communication abnormality, master control borad and one are occurred to the communication of above-mentioned line card Yu other communication nodes
Communication abnormality and master control borad occur for a line card and all line cards three kinds of Exception Types that communication abnormality occurs are default different respectively
Anomalous counts maximum value as its threshold value.If the communication abnormality situation of above-mentioned three types occurs, to corresponding exception
The anomalous counts of type carry out it is cumulative after, anomalous counts are compared with preset threshold value, so as to whether needing to make phase
The processing answered is judged.
Wherein, the threshold value of anomalous counts is preset according to the actual situation, such as：If not influencing normally to communicate or guarantee
Data threshold value can be arranged larger in the case where normal transmission.
It in the present embodiment, can be with when the anomalous counts of the communication abnormality of a certain Exception Type reach preset threshold value
It is handled by way of restarting line card or restarting master control borad, to restore normal communication in time, guarantees line card and line card
Between, between line card and master control borad or master control borad and line card data normal transmission.
In addition, in the present embodiment, the mode for handling communication abnormality can be customized by order line, as user can be with
The reboot time of line card or master control borad, the time etc. that setting network element device turns on or off are set by order line.
