Abstract
The embodiment of the invention provides a method for path fault test; the method includes the following procedures: the same test messages which are continuously received and are sent by in-ports of a path and of which the number is set are judged, when the test message is judged to be different from the test message currently used to test the path fault, the received test message replaces the test message currently used to test the path fault, the updated test message is used for the path fault test between in-ports of the path . The embodiment of the invention also provides a path fault test system and a device thereof. The invention resolves the problem that when the in-ports of the path revise the test messages, the following path fault test can not be implemented correctly because out-ports of the path can not correspondingly revise the test messages caused by the path fault.
Description
Technical field
The present invention relates to the fault detection technique in the communications field, relate in particular to the method, system and device that path failure detects.
Background technology
Along with multiprotocol label switching (MPLS; Multiple protocol label switching) technology more and more becomes Internet protocol (IP; Internet Protocol) key technology of network multi-service carrying; Label switched path (LSP, Label Switch Path) fault detect becomes the important topic that industry is paid close attention to.Referring to Fig. 1; Schematic network structure for lsp failure detection in the prior art; Comprise inlet LSR (Ingress LSR; Ingress Label Switch Router) and outlet LSR (Egress LSR, Egress Label Switch Router), and with the transfer of data of Ingress LSR LSP to Egress LSR.Ingress LSR is called the path inbound port, Egress LSR is called the path outbound port.
Based on the structure of Fig. 1, the method that existing lsp failure is detected describes below, and this method comprises:
Periodically insert Connectivity Verification/quick fault testing (CV/FFD, Connectivity Verification/Fast Failure Detection) message at Ingress LSR, the said CV/FFD message of insertion is sent to Egress LSR through LSP.To be used for the form and the frequency of CV/FFD message of path detection identical with being pre-configured in Egress LSR if Egress LSR detects form and the frequency of CV/FFD message of reception, shows the LSP operate as normal; If detect reception the CV/FFD message form and frequency and be pre-configured in Egress LSR to be used for the form and the frequency of CV/FFD message of path detection inequality; Show the normal fault of LSP; Then Egress LSR sends the back to defective indication (BDI through a reverse path to Ingress LSR; Backward Defect Indication) message, this lsp failure of notice Ingress LSR.Said reverse path can be LSP, also can be other path outside the LSP.The schematic network structure that LSP broke down during existing lsp failure detected is as shown in Figure 2.
Egress LSR detects after LSP breaks down, and is in defect state, will send BDI message to IngressLSR always; Detect LSP up to Egress LSR and recover normal; Just stop to send BDI message to IngressLSR, at this moment, Ingress LSR detects the BDI message of sending less than Egress LSR; Just think that the fault of this LSP eliminates, recover normal.
Facing CV message and FFD message down describes.The CV message is the same with the form of FFD message, and the cycle of just sending is different, and the period of sending the CV message is 1S, and sending FFD message period is 10ms, 20ms, 50ms, 100ms, 200ms or 500ms.To adopt the CV message during detection still be the FFD message by setting when Ingress LSR and the Egress LSR configuration detection message.
When Egress LSR detects,, be 0 or 1, when perhaps sum is greater than 4, then confirm corresponding lsp failure like continuous 3 the CV/FFD message totals of receiving more than the cycle that Ingress LSR sends if the consecutive periods of number is set.After confirming lsp failure,, think that then the fault of corresponding LSP is eliminated if in continuous 3 cycles, receive 2 to 4 messages altogether.
That carry out fault detect in Ingress LSR and Egress LSR correspondence is Operations, Administration and Maintenance (OAM; Operation; Administration and Maintenance) function, what carry out this OAM(Operation Administration Maintenance) is the state machine that is provided with respectively in Ingress LSR and the Egress LSR.
There is following problem in above-mentioned path failure detection method:
1) if being later than Egress LSR, Ingress LSR opens OAM(Operation Administration Maintenance); Perhaps, Egress LSR opens OAM(Operation Administration Maintenance) and Ingress LSR does not open OAM(Operation Administration Maintenance), the CV/FFD message that then can cause Ingress LSR also not have transmission to carry out fault detect; And Egress LSR has begun to carry out the reception detection of CV/FFD message; This will cause Egress LSR can't receive the CV/FFD message, just confirm corresponding lsp failure, report the warning of corresponding LSP fault to webmaster.And in fact, this moment, LSP was normal, and this fault alarm should not produce.
There is same problem when 2) stopping OAM(Operation Administration Maintenance); If Ingress LSR stops OAM(Operation Administration Maintenance) prior to Egress LSR; Ingress LSR no longer sends detection messages to Egress LSR, and Egress LSR is still detecting, and Egress LSR this moment is owing to can't receive the CV/FFD message that Ingress LSR sends; Just confirm corresponding lsp failure, report fault alarm to webmaster.In this case, this fault alarm is wrong.
3) when needs are revised type of message and/or frequency, must stop the OAM(Operation Administration Maintenance) that Ingress LSR then stops Egress LSR earlier, otherwise, with wrong fault alarm occurring.Such as; At first the OAM(Operation Administration Maintenance) of the OAM(Operation Administration Maintenance) of Ingress LSR and Egress LSR has all disposed the FFD message of 10ms respectively; Need be 20ms with the frequency modification of the FFD message of the OAM(Operation Administration Maintenance) of the OAM(Operation Administration Maintenance) of Ingress LSR and Egress LSR at present, if stop the OAM(Operation Administration Maintenance) of Ingress LSR earlier, the FFD message frequency errors that will cause Egress LSR to receive; Just confirm corresponding lsp failure, report the warning of corresponding LSP fault to webmaster.In this case, this fault alarm is wrong.
4) disposed different messages at Ingress LSR respectively with Egress LSR; With detection messages type and/or the frequency errors that cause EgressLSR to receive by Ingress LSR transmission; Then confirm corresponding lsp failure; The configuration error of this situation will cause Egress LSR to send BDI message to Ingress LSR always, notify Ingress LSR this lsp failure, and report the warning of this lsp failure to webmaster always.
In order to address the above problem, propose first packet in the prior art and triggered the scheme that lsp failure detects, this scheme comprises following 3 points:
1) first packet triggers the OAM(Operation Administration Maintenance) of Egress LSR.Be specially; In advance not at Egress LSR configuration OAM(Operation Administration Maintenance); The type of message and the corresponding frequencies that just are not used to detect in advance in Egress LSR configuration; Automatically write down its type of message and frequency thereof after after Egress LSR opens OAM(Operation Administration Maintenance), receiving first CV/FFD message that sends by Ingress LSR,, be used for lsp failure and detect as the OAM(Operation Administration Maintenance) of Egress LSR configuration.
2) consistency desired result function.Be specially; After Egress LSR first packet triggers OAM(Operation Administration Maintenance); If do not receive the CV/FFD message that sends by Ingress LSR in a period of time (said a period of time can by user oneself set) then send BDI message to Ingress LSR; Notify Ingress LSR corresponding lsp failure, and report fault alarm to webmaster.
3) dynamic start-stop protocol function.When Ingress LSR need revise type and/or the frequency of detection messages; Ingress LSR is with the fault detect and the isolation (FDI of expansion; Fault Detection andIsolation) message; Send to Egress LSR through LSP, notice Egress LSR stops OAM(Operation Administration Maintenance), and upgrades the detection messages that Egress LSR is used to carry out the LSP detection with the detection messages that sends to Egress LSR after the FDI message of expanding.Same reason, when Ingress LSR need stop OAM(Operation Administration Maintenance), Ingress LSR sent to Egress LSR with the FDI message of expansion through LSP, and notice Egress LSR stops OAM(Operation Administration Maintenance).
The applicant carries out in the research process in the technology that above-mentioned first packet is triggered the lsp failure detection, and should technology there be following problem in discovery:
Dynamically in the practice of start-stop protocol function, when Ingress LSR need revise detection messages type and/or frequency, Ingress LSR sent to Egress LSR with the FDI message of expansion through LSP, and notice Egress LSR stops OAM(Operation Administration Maintenance).If Ingress LSR sends in the process of the FDI message of expanding to Egress LSR through LSP; LSP is obstructed or congested, will cause the FDI message dropping of this expansion, causes Egress LSR can't upgrade the follow-up detection messages that LSP detects that is used to carry out; The detection messages that makes Ingress LSR and Egress LSR be used to detect is inconsistent; Egress LSR will send BDI message to Ingress LSR always, notify Ingress LSR corresponding lsp failure, and report fault alarm to webmaster.In this case, it is wrong reporting fault alarm to webmaster, and Ingress LSR receives after the BDI message, will stop to cause adverse consequences to operations such as Egress LSR transmission data.
By above analysis; Existing first packet triggers in the scheme of lsp failure detection; When Ingress LSR need revise detection messages, under situation such as LSP is obstructed or congested, just under the situation of lsp failure; Egress LSR to occur and report fault warning to the webmaster mistake, and the situation of notifying IngressLSR corresponding LSP fault by error.It is thus clear that existing path failure detection scheme is incomplete, when existing the path inbound port to revise detection messages, because of path failure causes the path outbound port can't the modify detection messages, cause making the follow-up problem that correct path failure detects of carrying out.
