Packet Transport Network PTN supports the multiple two-way point-to-point interface channel based on packet switching service, have point to point connect operation, management, safeguard (Operation Administration and Maintenance, OAM) mechanism.The inner definition of communication industry standard " requirement of Packet Transport Network (PTN) equipment and technology " has the alarm indication signal AIS function of PTN equipment, is mainly used in, in the time detecting service layer and break down, suppressing client layer alarm.In the time that the MEP of service layer detects Loss of continuity LOC or signal fault SF, send ais signal to the object MEP of client layer, for suppressing the alarm signal such as LOC of client layer.
Wherein, PTN layer is by Virtual Channel (Virtual Channel, VC) layer and virtual path (Virtual Path, VP) layer forms, for adopting MPLS-TP(Multiprotocol Label Switching-Transport Protocol, multiprotocol label switching-host-host protocol) the PTN equipment of technology, the VC layer of PTN is pseudo-line (PW) layer, VP layer is corresponding to LSP.
For instance, in this VP layer networking scene shown in Fig. 1, Section1(section 1) as the service layer of label switching path LSP 1, link between LSR A and LSR B breaks down, for example LSR A is in the time sending message to LSR B, LSR B does not successfully receive the message that LSR A sends in Preset Time section, and in the time that LSRB node detects Section1LOC fault, LSR B can insert LSR AIS message under LSP1.In the time that the egress point LSR in this path of LSP1 D receives this AIS message, can report the ais alarm of LSP1, and suppress the alarm of LSP1.
Again for instance, in this VC layer networking scene shown in Fig. 2, LSR B detects PW2OAM fault, can under PW1, insert PW AIS message, when LSR A receives the AIS message of PW1, can continue to insert PW AIS message under PW6.LSR F receives after the AIS message of PW6, thinks and service aisle fault is switched to protection channel, selects protection stream.
The embodiment of the present invention provides a kind of transmission method of fault message, as shown in Figure 3, comprising:
101, the LSR pair link adjacent with this equipment detects.
Wherein, LSR LSR is the switching equipment in MPLS network, and label exchange and label distribution function can be provided.In the scene of the networking shown in Fig. 1 and Fig. 2, data flow be bidirectional flow to, for example, in the networking shown in Fig. 1, the path of forwarding equivalence class process in MPLS network is called LSP, on a LSP, and the direction transmitting along data, adjacent LSP is called upstream LSR and downstream LSR, for example LSR A is the upstream LSR of LSR B, and LSR B is the downstream LSR of LSR A, and LSR A and LSR B also can be described as reciprocity LSR.
Exemplary, in the networking scene shown in Fig. 1, along data flow from left to right, LSR B can periodically receive the message that reciprocity LSR A sends, if LSR B does not receive the message of LSR A in Preset Time section, LSR B detects that the link between LSR A and LSR B breaks down.
If 102 LSRs detect that link breaks down, obtain the fault message of link, fault message comprises fault type, abort situation, faulty channel type and faulty channel identification information.
Concrete, if LSR B detects that adjacent link breaks down, obtain the fault message of this link by operating, manage, safeguard OAM mechanism.Wherein, OAM mechanism can be carried out performance monitoring and be produced maintenance information, according to the stability of these information evaluation networks, can also detect the fault that is over by the mode of regular inquiry, produces various maintenances and warning information etc.
Exemplary, in the networking scene shown in Fig. 1, if LSR B detects the link between LSR A and LRS B and breaks down, determine that by OAM mechanism loss of connectivity (Loss Of Continuity appears in the Section1 section between LSR A and LRS B, LOC) fault, and obtain fault message, this fault message just comprises fault type (Defect Type): loss of connectivity, the NE ID (unique identification LSR B equipment in network) of abort situation (Defect Location): LSB, faulty channel type (Defect Channel Type): Section, faulty channel ID(Section Channel ID): that 1(represents is Section1).
Exemplary, in the networking scene shown in Fig. 2, if LSR B detects the link PW2 fault between LSR B and LSR C, determine between LSR B and LSR C and occur PW LOC loss of connectivity fault by OAM mechanism, and obtain fault message, this fault message just comprises fault type: loss of connectivity, abort situation: the NE ID of LSR B, faulty channel type: PW, faulty channel type i D:2(represent it is PW2).
103, LSR sends warning message to the egress point on data traffic direction of transfer, and warning message comprises fault message, so that egress point obtains fault message by resolving warning message.
Exemplary, in the networking scene shown in Fig. 1, when LSR A transmits data to LSR B, when LSR B has determined after fault message, LSR B can insert LSP AIS message under LSP1, this LSP AIS message will carry the determined fault message of LSR B, along with the rightabout of the reciprocity LSRA of LSR B, and send fault message to the party egress point LSR D upwards by LSR C.In the time that LSR D receives this AIS message, by resolving this AIS message, to get the more comprehensive fault message in fault point: loss of connectivity fault appears in the Section1 being positioned on LSR B.During this time, here only for forwarding AIS message, do not carry out alarm for the LSR C that forwards fault message.LSR D is being resolved to after fault message, and these fault messages are presented, and can, so that network manager finds abort situation rapidly, further fix a breakdown.
Exemplary, in the networking scene shown in Fig. 2, LSR C is transmitting to LSR B in the direction of data, if PW2 breaks down and has determined after fault message, LSR B can insert PW AIS message under PW1, this PW AIS message just carries this fault message, LSR A is in the time receiving the AIS message of PW1, can continue to insert PW AIS message under PW6, LSR A can inherit the fault message in the AIS message of the PW1 receiving get off simultaneously, be that LSR A also can report to the police, wherein LSR A carries fault message equally to slotting AIS message under PW6, like this, LSR F is in the time receiving the AIS message of PW6 transmission, by analytic message content, just can get the more comprehensive information in fault point: loss of connectivity fault appears in the PW2 being positioned on LSR B, and these information are presented, LSR F can think service aisle fault, be switched to protection channel, select protection stream, also be convenient to network manager and find rapidly abort situation, further fix a breakdown.
In the above description, the field format of the fault message carrying in AIS message wherein can be fixed field form, can be also type-length-value (Type-Length-Value, TLV) field format.Wherein, fault message fixed field form can be as shown in table 1.

| Cycle does not mate | 2 |
| MEP ID does not mate | 3 |
| MEG ID does not mate | 4 |
| SD error code | 5 |
| SF error code | 6 |
| Port DOWN | 7 |
Wherein, loss of connectivity can be because hardware is malfunctioning or malfunctioning the stopping of software receives CCM(continuity check message from a reciprocity MEP; Continuity Check Message) message; The cycle cycle of not mating the message that can receive as receiving terminal for LSR and the cycle that self sends message do not mate; MEP ID does not mate and can carry correct MEG rank for MEP has received one, but has carried incorrect MEP ID; MEG ID does not mate and can carry correct MEG rank for MEP receives, but has carried incorrect MEG ID; SD(Signal Degrade Signal Degrade) error code and SF error code can cause service security problem for Signal Degrade; Port DOMN can be link veneer port DOWN.Here, the correspondence of fault type and types value just schematically, is not limited to this, can be also other corresponding relation, is pre-configured in each LSR, does not also limit for fault type.
Defect Location(abort situation), can account for 4 bytes,, can represent by LSR ID to location of fault for label detection, also can identify with other information of network element.
Defect Channel Type(faulty channel type) can take 1 byte, label detection detects the channel type of fault, can apportioning cost as shown in table 4.
Table 4 faulty channel type
| Faulty channel type | Types value |
| Port | 1 |
| Section | 2 |
| LSP | 3 |
| PW | 4 |
| PW?APS | 5 |
Wherein, port refers to physical layer port, and the position of breaking down is device port; Section is the section breaking down of VP layer; The end-to-end access path that lsp failure passage is LSR breaks down; PW faulty channel is danger end to end and breaks down; PW APS faulty channel is for controlling protects the APS function of switching to break down.Certainly, the faulty channel type is here not limited to this, does not also limit for the corresponding relation of faulty channel type and types value.
Defect Channel ID(faulty channel ID), can take 4 bytes, the ID of the faulty channel that label detection arrives.For example faulty channel type is PW, and faulty channel ID can be PW ID; If faulty channel type is port, faulty channel ID can be just BoardID(1Byte)+SubBoardID(1Byte)+PortID(2Bytes).
Like this, in the time of link occurs fault, LSR just can send to egress point by preset kind value and identification information, so that egress is named a person for a particular job, these information present, and are convenient to webmaster personnel and find fast abort situation.
