Detailed description of the invention
In embodiments of the present invention, the first data message is sent according to the packet information being pre-configured with to backup link；Receive the second data message being backed up link loopback；Described second data message is detected in real time, it is thus achieved that testing result；Report described testing result.
Here, described backup link is the backup link corresponding with primary link.
Below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
Fig. 1 is the schematic flow sheet that the embodiment of the present invention realizes the method for link detecting, as it is shown in figure 1, the method that the embodiment of the present invention realizes link detecting includes:
Step S101: send the first data message to backup link according to the packet information being pre-configured with；
Wherein, described backup link is the backup link corresponding with primary link.The described packet information being pre-configured with includes length, packet sending speed, packet header number, bag tail number and bag content format.
Here, described Bao Changke thinks fixed value or incremented/decremented ordered series of numbers, and correspondingly, the first data message sent can be fixed length bag, or incremented/decremented length bag；Described packet sending speed can be fixed rate, or step rate；Described bag content format can be configured by user, as long as the flow control signal of backup link can be supported.
Specifically, it is achieved the device of link detecting sends the first data message by the interface pre-set to backup link.Wherein, arranging of interface can be arranged according to the interface protocol of backup link.Owing to each backup link can support multiple different agreement type, so realizing in the embodiment of the present invention device of link detecting can pre-set the interface supporting different agreement type.
Step S102: receive the second data message being backed up link loopback；

Further, as it is shown on figure 3, after described step S1032, described method also includes:
Step S1034: when described judged result be described statistical result meet the first packet header bag tail pre-conditioned time, the packet content in described second data message is carried out error checking, it is thus achieved that testing result.
Here, described error checking that packet content in described second data message is carried out can be through cyclic redundancy check (CRC) (CRC) mode the packet content in described second data message carried out error checking, to determine whether described backup link exists error code.
Step S104: report described testing result.
Specifically, it is achieved the testing result of acquisition is reported system by the device of link detecting in real time.So, system can learn the duty of described backup link according to testing result.
Here, when described testing result be described statistical result be unsatisfactory for the first packet header bag tail pre-conditioned time, then according to described testing result, system can determine that the duty of described backup link is fault；When described testing result is be absent from error code in described backup link or there is error code and when the bit error rate is in tolerance interval, then according to described testing result, system can determine that the duty of described backup link is normal；When described testing result is there is error code and the bit error rate in described backup link beyond tolerance interval, then according to described testing result, system can determine that the duty of described backup link is fault.
