Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
As shown in Figure 2, be one of the fault detection method in the embodiment of the invention concrete schematic flow sheet, this flow process comprises:
201, current maintaining end point receives the communication with detection message that other maintaining end points are sent in the network, and the overtime situation that sends communication with detection message according to described other maintaining end points detects the maintaining end point that obtains breaking down.As, current maintaining end point (as being the MEP1 among Fig. 1) receives the communication with detection message that other maintaining end points periodically send in the network (as can be the CCM message in the 1AG agreement, in other agreements, can be the message that other realize the communication with detection function); MEP1 surpass the preset threshold value time (as, 2 times or 3.5 times of times in described cycle) after, also do not receive a certain maintaining end point (as second maintaining end point) or a plurality of maintaining end point (as second, third ... wait maintaining end point) the CCM message that sends according to described cycle, since contain in the CCM message sender identification information, MAC Address, transmit Sequence Number and other agreement relevant informations etc., therefore MEP1 can be known the information of the maintaining end point that fault has taken place according to the situation of the CCM message that receives, as maintaining end point identification information, MAC Address etc.
Wherein, maintaining end point can be configured on the multiple communication equipment, comprises network side and end side, as long as support the equipment of 1AG agreement just can dispose MEP.
202, generate the first communication with detection message, the described first communication with detection message carries the fault terminal point information, and described fault terminal point information is used to identify the described maintaining end point that breaks down; Wherein, the first communication with detection message can comprise the sign of the maintaining end point of fault, or also comprises in order to whether the remote defect indication (rdi) sign of maintaining end point fault is arranged in the marked network.Wherein, the sign of the maintaining end point of described fault comprises described other maintaining end point signs of at least one fault.The medium access control of the maintaining end point that is designated described fault of the maintaining end point of described fault (Media Access Control, MAC) the agreement relevant identifier of the maintaining end point of address, IP (internet interconnection protocol, Internet Protocol) address or the described fault of other unique identifications.Should be understood that: distinguish for the communication with detection message that other maintaining end points in the network that receives with current maintaining end point are sent, the communication with detection message of Sheng Chenging is called the first communication with detection message here.
203, in network except that current maintaining end point other maintaining end points send the described first communication with detection message, make other maintaining end points in the network from this first communication with detection message, extract the fault terminal point information and report.
Should be understood that, communication with detection message can be that multicast sends, the destination address that is communication with detection message is a multicast address, makes the maintaining end point (communication equipment) that needs to safeguard in the network can receive this multicast message smoothly and be unlikely to cause broadcast storm; Also can be with clean culture, appoint and to broadcast or other modes send communication with detection message.
Further, as shown in Figure 3, following flow process is arranged for other each maintaining end points (is example with second maintaining end point) that receive this first communication with detection message:
301, described second maintaining end point receives the first communication with detection message;
302, described second maintaining end point obtains the fault terminal point information from the described first communication with detection message, and this fault terminal point information may comprise the information of second maintaining end point, also may not comprise;
303, described second maintaining end point reports described fault terminal point information, as report the system manager of second maintaining end point, like this this system manager according to this fault terminal point information and equipment local preserve comprise the whole network all devices database of information, networking information, can orient the equipment that has fault in the network in real time comprehensively, and do further processing in view of the above.As, LB, LT handles, specifically be meant: in the 1AG agreement, comprise three kinds of messages: CCM message, LB message, LT message, the CCM message is used for detecting connectivity of link, and the LB message provides the function that is equivalent to PING, and the LT message provides the function that is equivalent to TRACE, be to come orientation problem in the 1AG agreement, therefore can handle the actual conditions of the equipment that has fault in the fixer network with LB, LT by LB message and LT message.
As shown in Figure 4, be a network system with 7 equipment.Comprise 7 equipment in this system, dispose MEP in 4 equipment, dispose in 3 equipment and safeguard that (Maintenance IntermediatePoint, MIP), each MEP connects and communication by corresponding MIP intermediate node.
Send the CCM message such as the periodic multicast of MEP1, these messages are through intermediary network device MIP, and MIP duplicates the CCM message of suitable number of times and transmits past different network branches according to forwarding strategy.Through repeatedly forwarding, final MEP2, MEP3 and MEP4 can both periodically receive the CCM message from MEP1.
Equally, MEP1 also can periodically receive from MEP2, the CCM message that MEP3 and MEP4 send.Occurred fault in network shown in Figure 4: single-channel fault (can receive message and can not send message) has appearred in two sections networks that connect MEP2 and MEP4 in the network, this moment, MEP2 and MEP4 and miss had this fault, still send the CCM message (still according to original CCM transmission cycle, in fact these messages since the single-channel fault of MEP in the single-pass network, in fact abandoned quietly) and receive CCM message from other MEP.
MEP1 has detected above-mentioned fault: MEP1 and has not received the CCM message that MEP2 and MEP4 send, and send all after dates at the CCM message that surpasses 3.5 times and also do not receive the CCM message that sends from MEP2 and MEP4, then MEP1 determines that fault has appearred in these two MEP, as not receiving CCM message from MEP2 because surpass 3.5 times of transmission cycles, the then overtime and alarm of report MEP2 in the MEP1 reporting information, the system manager of MEP1 suspects that at this moment fault has appearred in MEP2, so, initiate the LT test from MEP1 to MEP2, so, two MIP in the centre can produce response message to this LT, and transmission is not gone out but MEP2 can receive LT message response message.The result that system manager at the MEP1 place returns by observation concludes that fault has appearred in MEP2.To the detection of MEP4 in like manner.
After MEP1 determines that fault has appearred in MEP2 and MEP4, in the CCM message that after MEP1, sends, carry remote bug indication (Remote Defect Indication, RDI) (this identifies available 0 sign fault-free to sign, with 1 sign fault is arranged, can there be the fault recovery up to faulty equipment in this RDI sign always) and the MEP ID of MEP2 and MEP4 (as, MAC Address, IP address or other can unique this equipment of appointment the agreement relevant identifier), the simplification form of this CCM message is as shown in Figure 5.Wherein, " the Failed MEP TLV (MEP2ID) " in the CCM message and " Failed MEP TLV (MEP4ID) " have identified MEP2 and MEP4 fault respectively.Certainly, if this CCM message is not the CCM message that defines in the 802.1ag agreement,, the corresponding message of other protocol definitions indicates but then also can not comprising RDI.
Accordingly, the fault message that carries of the message of the CCM that sends of MEP3 is consistent with the fault message that MEP1 carries.MEP4 does not receive the CCM message of MEP2, can receive the CCM message of MEP1 and MEP3, therefore the CCM message of MEP4 has only carried the fault message (can infer that in like manner the CCM message that MEP2 sends only carries the fault message of MEP4) of MEP2, and the message format of its simplification as shown in Figure 6.Wherein, " the Failed MEP TLV (MEP2ID) " in the CCM message identified the MEP2 fault.
MEP2 receives the processing behind the CCM message: for MEP2, it can receive the CCM message from the form of MEP1 and MEP3 such as Fig. 5, also can receive from the form of MEP4 such as the CCM message of Fig. 6, and these messages have all indicated MEP2 fault to occur.MEP2 receives behind these CCM messages the fault information reporting in the message, as report the system manager, the system manager is by the comparative analysis to the CCM message that carries fault message, local CCM database and the networking situation that receive, the fault of certain form has appearred in the network that can judge the sending direction of MEP2, and then takes appropriate reclamation activities.
As, the system manager at the MEP2 place can receive the CCM message from MEP1, this CCM message carries the fault message that contains MEP2ID, after the system manager knows this information, generally, can attempt initiating the LT of MEP1 is tested at the MEP2 place.Because message sends and not go out, therefore two MIP and MEP1 do not have response message.According to this information, the system manager of MEP2 conclude problem go out MEP2 itself or with link that MEP2 links to each other on, after this, the system manager at MEP2 place can attempt solving this problem in two ends packet capturing that links to each other with MEP2 or equipment or the link of replacing fault.
The system manager who is in the MEP4 side equally also can infer that in conjunction with local CCM database the fault of certain form has appearred in the network of the sending direction of MEP4 according to the fault message that reports, and then takes appropriate reclamation activities.
In the technical scheme of present embodiment, when a certain maintaining end point is found faulty equipment is arranged, in the CCM message that sends thereafter, carry the fault terminal point information, make the recipient of CCM message to know that from this CCM message fault has taken place which equipment.Particularly take place to send fault when receiver equipment, but during just often situation of receiving function, this receiver equipment can report the information of faulty equipment.The system manager who obtains this receiver equipment that reports just can know in real time that fault has taken place this equipment, and handles according to fault.
