Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The invention provides a kind of method of detection messages Cheng Huan, with reference to shown in Fig. 1, comprise following flow process:
101, within the time period of presetting, detect the number of the message that the port of arbitrary protection node in ethernet ring network receives.
Here the message transmitted on the loop of ethernet ring network comprises: service message and Ethernet ring protection protocol massages.Loop due to ethernet ring network is mainly used for service message transmission; and when Ethernet ring protection protocol massages is when transmitting in ethernet ring network with service message simultaneously; if now the loop of ethernet ring network forms message Cheng Huan; then Ethernet ring protection protocol massages can take the transmission bandwidth of service message; therefore the message number by detecting the Ethernet ring protection protocol massages in ethernet ring network loop on the port of the arbitrary protection node of ethernet ring network is needed, to realize the real-time adjustment to the too message number of looped network protection protocol massages in ethernet ring network loop.
When the number of the message 102, received on the port of this arbitrary protection node exceedes default message number threshold value, then check whether the port of arbitrary protection node is port blocked.
Wherein message number threshold value be protection node place loop on message non-state circlewise time, the maximum of the number of the message that the port of this protection node can receive within the time period of presetting, the port of any node wherein protecting the port of node and ERPS Ethernet ring protection to switch, concrete, if the port of protection node is the fastest per secondly can receive a message, then in one minute, port can receive 60, if the message number received in a minute more than 60 can, might occur that Ethernet Circle is abnormal, and when the message in ether loop becomes ring, the message number of reception per minute is at least 180, now then can using 180 of a reception per minute message as message number threshold value, namely the embodiment of the present invention can be one minute with the time period of presetting, message number threshold value is 180 is example, but be not limited only to this situation in practical operation.
If the port of 103 arbitrary protection nodes is port blockeds, then by this port blocked to ethernet ring network alarm, and this port blocked be set forbid E-Packeting.
Here, after prohibiting the function that port blocked E-Packets, the forwarding of message on the protection node at this port blocked place can just be stopped.
Wherein, if the port of protection node is port blocked, then port blocked is set and forbids message repeating.Here the port blocked on loop has one at least; when port blocked detecting the message number received exceedes default message number threshold value; now the loop at port blocked place has defined the phenomenon of message Cheng Huan; namely port blocked may for mistake be configured to the Virtual Channel on ethernet ring network not enable; port blocked just loses the function that the protection node of original prevention message at port blocked place continues to forward; therefore cause port cycle corresponding to each protection node repeatedly to receive the message of same content, cause message in loop to become ring to circulate.Here stopping forwarding message by reconfiguring port blocked, therefore when message repeating is to the protection node at this port blocked place, stops and further forward the packet to other protection nodes, avoiding message Cheng Huan.
Optionally, the loop at arbitrary protection node place at least comprises the protection node that has port blocked, namely a loop with Virtual Channel at least configures a port blocked.
The method of the detection messages Cheng Huan that the embodiment of the present invention provides; judge, in loop, whether message Cheng Huan occurs by the message number of the port accepts detecting protection node in ethernet ring network loop; and in message Cheng Huanhou is by loop, protect the port of node to report to the police to ethernet ring network; and control to stop the message repeating in loop, solve the problem of message Cheng Huan in ethernet ring network loop.
Further, with reference to shown in Fig. 2, the method for detection messages Cheng Huan provided by the invention is further comprising the steps of:
If the port of 104 arbitrary protection nodes is not port blocked, then the number of the message that the looped network protection link port on the continuous loop detecting arbitrary protection node place at least two preset time period receives.
If the number of the message that 105 these looped network protection link port detected at least two preset time period continuously receive all exceedes default message number threshold value; then by looped network protection link port to ethernet ring network alarm, and looped network protection link port be set forbid E-Packeting.
Here the preset time period in step 105 is consistent with the preset time period in step 102, and the message number threshold value preset in step 105 is also consistent with the message number threshold value preset in step 102.Wherein,
The embodiment of the present invention is to detect 3 minutes continuously, namely in 3 minutes, all occur in loop per minute that the message number of the port accepts of protection node exceeds the situation of default message number threshold value, now according to testing result by the looped network protection link port in the loop at this arbitrary protection node place to ethernet ring network alarm, the phenomenon of message Cheng Huan has been defined in the loop at looped network protection link port place here, now illustrate looped network protection link port place loop on there is no port blocking message repeating, now then by looped network protection link port to ethernet ring network alarm and arrange forbid message repeating.Here looped network protection link port RPL (Ring Protection Link) is port corresponding to RPL Owner node, and wherein RPL port is for forbidding the looped network protection link port RPL Port message that this RPL port place loop forwards.
Optionally, the loop at arbitrary protection node place only includes the protection node that has looped network protection link port.
Optionally, be whether the detection method of port blocked to the port of arbitrary protection node with reference to step 102, loop due to arbitrary protection node place at least comprises the protection node that has port blocked, therefore the method provided in the present embodiment also comprises after step 104: if the number of the message that the port of the arbitrary protection node detected at least two preset time period continuously receives all exceedes default message number threshold value, then by detecting on this loop whether the port of other protection nodes is port blocked, and by the port blocked that detects to ethernet ring network alarm, and this port blocked detected is set forbids message repeating.
The method of the detection messages Cheng Huan that the embodiment of the present invention provides; judge, in loop, whether message Cheng Huan occurs by the message number of the port accepts detecting protection node in ethernet ring network loop; and in message Cheng Huanhou is by loop, protect the port of node to report to the police to ethernet ring network; and control to stop the message repeating in loop, solve the problem of message Cheng Huan in ethernet ring network loop.
