Embodiment
For make goal of the invention of the present invention, characteristic, advantage can be clearer, understandable; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment only is the present invention's part embodiment, but not whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
With reference to Fig. 1, a kind of flow chart that triggers the method for bypass equipment switching that Fig. 1 provides for the embodiment of the invention one.As shown in the figure, this method comprises:
Step S101: the real-time traffic that detects forthright equipment;
Preferably, can regularly detect the incoming interface flow of said forthright equipment and the tactful packet loss flow of outgoing interface flow and said forthright equipment; Concrete, the incoming interface flow of said forthright equipment can be meant the total amount of the packet that in sense cycle, flows through said forthright equipment incoming interface; Said outgoing interface flow can be meant the total amount of the packet that in proof cycle, flows through said forthright equipment outgoing interface; Said tactful packet loss flow is meant the packet loss flow that the forthright equipment self disposes in order to carry out present flow rate control, so in the application embodiment, said tactful packet loss flow can directly read.
Preferably, also can regularly detect the incoming interface flow of said forthright equipment and the mistake bag number of said forthright device interior statistics.Those skilled in the art can know; Each chip of forthright device interior is when the transmission data; Unavoidably have packet and pass wrong situation,, be referred to as wrong bag passing wrong packet here in order to narrate conveniently; Concrete, the mistake bag number of said forthright device interior statistics can be meant the summation of the mistake bag number of each chip statistics of said forthright device interior.
Step S102: judge whether said forthright equipment Traffic Anomaly takes place;
Concrete; Judge said forthright equipment whether take place Traffic Anomaly method can for; According to the incoming interface flow and the outgoing interface flow of said forthright equipment, and the tactful packet loss flow and the sense cycle of said forthright equipment, calculate the packet loss of said forthright equipment;
Concrete, said packet loss can be through calculating the difference of said incoming interface flow and said outgoing interface flow and said tactful packet loss flow, said difference and said sense cycle done division arithmetic obtain, and promptly packet loss can be by following formula calculating:
Packet loss=(incoming interface flow-outgoing interface flow-tactful packet loss flow)/sense cycle
Behind the packet loss that obtains said forthright equipment; Said packet loss and preset packet loss threshold value are compared; When said packet loss during, confirm said forthright equipment generation Traffic Anomaly, otherwise think that Traffic Anomaly does not take place said forthright equipment greater than said preset packet loss threshold value.
Wherein, said packet loss threshold value can be provided with according to the practical experience value, and for example, when said forthright equipment did not have collocation strategy packet loss flow, said packet loss threshold value can be 20%; In said forthright equipment disposition during tactful packet loss flow, said packet loss threshold value can be 30%, can also be set to other value according to actual needs certainly, does not do concrete qualification here.

Mistake bag number/(the incoming interface flow * sense cycle) of Packet Error Rate=forthright device interior statistics
Said Packet Error Rate and preset Packet Error Rate threshold value are compared,, confirm said forthright equipment generation Traffic Anomaly, otherwise think that Traffic Anomaly does not take place said forthright equipment when said Packet Error Rate during greater than said Packet Error Rate threshold value.
Said Packet Error Rate threshold value can be set according to the practical experience value, for example, can be set to 5%, certainly other value can also be set according to the actual requirements, does not do concrete qualification here.
Preferably; The method whether above-mentioned two kinds of detection forthright equipment Traffic Anomaly takes place can only exist a kind of; Also can exist simultaneously, promptly calculate packet loss, and also calculate Packet Error Rate when packet loss compared with preset packet loss threshold value; And Packet Error Rate and preset Packet Error Rate threshold value compared; When above-mentioned two kinds of methods exist simultaneously,, packet loss sent out Traffic Anomaly if, just explaining forthright equipment greater than said preset packet loss threshold value and/or said Packet Error Rate during greater than said Packet Error Rate threshold value.
Step S103: when said forthright equipment generation Traffic Anomaly, send and be used to trigger the indication message that said bypass equipment switches to communication link in the protection path; Otherwise return execution in step S101.
When detecting said forthright equipment generation Traffic Anomaly, send indication message to said bypass equipment, after said bypass equipment receives said indication message, communication link is switched to the protection path, improved the reliability that bypass equipment switches.
Preferably, in order further to optimize the foregoing description, said method also comprises:
Monitor the warning information of each module in the said forthright equipment, when module is sent warning information, send switching indication to said bypass equipment and switch to the protection path to trigger said bypass equipment.
