Description
Technical field
The invention belongs to network communication field more particularly to a kind of processing methods of alarm and linkage support (IAS) system.
Background technology
Packet Transport Network (PTN, Packet Transport Network) is based on packet switch, connection-oriented more industry
The unified tranmission techniques of business, can preferably carry carrier ethernet business, meet traffic criteria, high reliability, flexible expansion
Property, 5 essential attributes, the wherein OAM such as stringent QoS (QoS) and perfect Operation Administration and Maintenance (OAM) be to reduce network
The important means of maintenance cost, OAM(Operation Administration Maintenance) is particularly significant in public telecom network, especially to needing to provide service quality guarantee
Network, OAM can simplify network operation, examine network performance and reduce network operation cost.In general, PTN network is mainly wrapped
3 levels are included, are Virtual Channel (Virtual Channel) layer, virtual path (Virtual Path) layer and virtual segment respectively
(Virtual Section) layer, the bottom of PTN is physical media layer network, for transmitting MPLS (TMPLS) OAM technologies, PTN
VC layers be pseudo-wire layer (TMC), VP layer be tunnel layer (TMP), VS layers as physical segment layer (TMS).The OAM of PTN network
Primarily with respect to the OAM defencive functions of network, detection, switching and node reliability including network etc., with edge-to-edge
For 3 business of pseudo wire emulation (PWE), network there are different level fault detect and protection, referring to Fig. 1.
As it can be seen that the different levels of PTN network can dispose different detection and protection, such as tunnel level, can dispose
The TMP detections of TMPLS OAM can also dispose tunnel (tunnel) two-way converting detection (BFD), different detections and protection hand
Duan Yingyong is in different network layers.
The detection technique of different level can be bound mutually, and the linkage detected between switching must be a level
, the protection of different level has corresponding handoff technique, can protect the OAM of PTN and be broadly divided into 6 levels, referring to Fig. 2 institutes
Show, this 6 levels are respectively：
1) L2 links (LINK) level：It is the protection based on physical port and virtual LAN (VLAN), which is in
The bottom is the OAM of link layer, corresponding to have Connectivity Fault Management (CFM) port+VLAN detections, first mile of ether
The TMS detections of net (EFM), TMPLS OAM, corresponding handoff technique have multi-link aggregated group (Multi-Chassis Link
Aggregation Group, MC-LAG) link aggregation.This layer is that detection to two layers of physical port and IP route nothing
It closes；
2) L3LINK levels：It is the protection based on three layers of outgoing interface and next-hop ip address, corresponding detection technique has
Link BFD, ping detection etc., for the link BFD of IP realities interface detection, can notify the quick heavy-route (Fast of IP
ReRoute, FRR), for the protection of the practical outgoing interface in tunnel, corresponding link BFD can notify traffic engineering (te))
FRR switches over protection；
3) label switched path (Label Switched Path, LSP) level：It is the protection based on LSP links, is divided to two
Attribute, first, the LSP that tag distribution protocol (LDP) signaling is established, (forwarding is of equal value for forward error correction (FEC) for link characteristics
Class), it is detected as LDP LSP BFD accordingly, protects corresponding LSP links, corresponding handoff technique is LDP FRR；Second is that base
In the tunnel LSP that Resource Reservation Protocol (RSVP TE) signaling of Traffic Engineering extensions is established, link characteristics are tunnel number and LSP
It identifies (ID), is detected as RSVP TE LSP BFD accordingly, it is corresponding to be switched to TE Hot Spares (hot-standby)；
4) tunnel level：It is the protection based on tunnel (tunnel).For tunnel, it can be realized between two tunnels
1: 1 or 1+1 backup protection, corresponding detection technique have the TMP detections of TMPLS OAM and MPLS OAM, corresponding switching is
Protecting tunnel group is notified to switch over by automatic protection switching (Automatic Protection Switching, APS)；
5) PW levels：It is the protection for entering label based on internal layer VC, corresponding detection technique has PW BFD and TMPLS OAM's
TMC layers of detection can be switched with PW FRR protected accordingly；
6) opposite end (Peer) level：It is the protection based on peer addresses, this layer is relatively to be independent, and belongs to point-to-point
Protection, can be detected with peer BFD, and corresponding handoff technique is three-layer VPN FRR.
Therefore various detections and the protection technique of PTN network deployment, there is no directly close between detection and protection
System, they are got up by entity associated, and for protection, he is only concerned the state of entity, as long as entity fault is just initiated to protect
Shield, and be not relevant for entity fault and detected by what means.For example, tunnel is an entity, in this entity
On, can disposing TMPLS OAM, either BFD is detected in combination with protecting tunnel group or FRR progress network switching guarantors
Shield, for protecting tunnel group or FRR, he is only concerned the state in tunnel, as long as tunnel failure will initiate to switch, and simultaneously
The failure for being indifferent to this tunnel is that TMPLS OAM or BFD detected on earth, so should not between detection and protection
It is directly linked.

The powerful OAM(Operation Administration Maintenance) of PTN network is exactly to require network that can be quickly detected failure, trigger protection after breaking down
It switches, it is desirable that the performance of handoffs of network is less than 50ms, and IAS is even more important other than as the bed course between detection and business
The reason is that in the distributed apparatus of PTN network, the IAS alarms that response detection generates at the first time, realization is switched fast, reaches
To the purpose of quick protection network, the performance of handoffs of network is made to be less than 50ms, when network disposes a large number of services, switching
It can be also not a halfpenny the worse.
The processing method of alarm provided in an embodiment of the present invention includes：
Step 1: linkage support (IAS) system receives the warning information of input；
Step 2: the warning information is converted to unified announcement by the IAS systems according to preset alarm representation method
Alert argument structure；
IAS should have a kind of unified alarm representation method as all systems for alerting and being uniformly processed, first IAS, both
All features of an alarm can be described, while to the newly-increased of other follow-up alarms and are easy to extend.IAS provides a kind of as a result,
Unified alarm representation method come describe one alarm essential characteristic.
The alarm representation method mainly usually describes an alarm using following member：
1) alarm source IAS_SOURCE represents the type or alarm event of detection of connectivity agreement, for example alarm source can
It is expressed as：
IAS_SOURCE_TMPLSOAM represents the LOC alarms of TMPLS OAM protocol detections；
IAS_SOURCE_BFD represents the session down alarms of BFD protocol detections；
IAS_SOURCE_CFM represents that alarm is lost in the distal end of CFM protocol detections；
IAS_SOURCE_PHYDOWN represents physical port down alarms；
IAS_SOURCE_CARD_EVENT represents offline of line card event alarm；
Here line card (Line card) represents PTN device, such as the visit of interchanger, router or other network equipments
Ask a kind of equipment interface between circuit and access equipment.Number and simulation line card with a variety of rates, may serve to connect
Cable or fibre circuit.Digital line card is mainly that data network provides data packet forwarding, ping response and packet fragmentation etc.
Function.Heretofore described line card refers mainly to the interface card in PTN distribution switch equipment.
2) alarm status IAS_ALARM_STATE, represents the state of alarm, and alarm status mainly has：
IAS_ALARM_STATE_DOWN：Represent that detection loss of connectivity alarm generates；
IAS_ALARM_STATE_UP：Represent detection loss of connectivity alarm clearance.
3) level is alerted, the detection level of alarm is represented, referring to Fig. 2, alarm level can be divided into：
L2LINK_LEVEL：This layer of main detection object is physical port；
L3LINK_LEVEL：This layer of main detection object is three layers of outgoing interface and next-hop ip address；
LSP_LEVEL：The LSP paths of LSP or RSVP that this layer of main detection object is LDP；
TUNNEL_LEVEL：This layer of main detection object is tunnel；
PW_LEVEL：This layer of main detection object is pseudo-wire；
PEER_LEVEL：This layer of main detection object is peer IP address.
4) alarm object parameter represents the object entity of various detection protocol detections, each level is protected based on front OAM
The detection object entity of OAM detections all in PTN network can be summarized as by the description of the basic element of detection：
GlobalPort：Corresponding L2LINK_LEVEL, detects two layers of physical port；
VlanId：Corresponding L2LINK_LEVEL detects the ID marks of VLAN；
OutIndex：Corresponding L3LINK_LEVEL detects the index of three layers of outgoing interface；

PeerAddress：Corresponding PEER_LEVEL detects the IP address of peer equipment.
Alarm the representation method unified IAS, mainly by above-mentioned alarm source, alarm status, alarm level and alarm object
4 part of parameter forms, which can represent alarm or the equipment of all detection of connectivity protocol detection
Some alarm events, durability is good, is easy to various alarm extensions.It, will be various by IAS after a variety of different alarms input to IAS
Different alarms is converted into the unified alarms of IAS and represents structure, then carries out various processing to alarm；
Step 3: the IAS systems detect network failure according to the warning information of the alarm parameter structure, network is triggered
Protection.
The step includes：The IAS systems determine that IAS cross-lines card is broadcasted according to the warning information of the alarm parameter structure
Flag set, then the warning information is subjected to the broadcast of IAS cross-lines cards；The IAS systems are according to the alarm parameter structure
Warning information determines that alarm source rapid switching function switch is enabled, then carries out being switched fast processing；The IAS systems are according to
The warning information of alarm parameter structure determines that the quick breeding function switch of alarm source is enabled, then carries out quick breeding processing；It is described
IAS systems determine that alarm source fast mapping functional switch enables according to the warning information of the alarm parameter structure, then carry out fast
Fast mapping processing；Alternatively, the IAS systems determine that alarm source quickly binds work(according to the warning information of the alarm parameter structure
It can switch and enable, then carry out quick binding processing.
Above-mentioned IAS systems, including being switched fast, quickly breeding, fast m apping, quick binding, alarm cross-line card are broadcasted
Etc. functions, main purpose be when network failure, can the various alarms of quick response, trigger network protection, make the switching of network
50ms can be met.Various alarms are all after detection failure generates, just to input to IAS at the first time, then IAS carries out protection switching
Processing when network configuration large capacity applied business, is alerted after the quick processing of IAS various performances optimization, performance of handoffs also milli
It is in no way inferior, meet the requirement of large capacity carrier ethernet protective value, so IAS is also believed to protect switching treatable
System.
As shown in figure 3, for the flow chart of processing method embodiment that the present invention alerts, which includes：
Step 301, alarm input；
Alarm inputs to IAS, and for sender, some essential informations that filling is needed to alert are including alarm source, alarm
It is no that IAS is needed to carry out cross-line card broadcast flag and alarm specifying information, if for example, thering are TMPLS OAM alarms to need to input to
IAS, alarm source can be expressed as IAS_SOURCE_TMPLSOAM, the specifying information of alarm, for example be that TMP layers of detection can be taken
Tunnel ID with detection, meanwhile, the flag set that IAS whether is needed to carry out cross-line card broadcast can will be alerted, represent the alarm
IAS is needed to carry out cross-line card broadcast；
Whether alarm here needs IAS to carry out cross-line card broadcast flag, is mainly based upon the spy of PTN distributed apparatus
Point consider, for distributed apparatus, the module usually detected, as TMPLS OAM, BFD due to hardware resource limit, detection it is hard
Part resource is only distributed on a line card, then, the alarm of detection also only can have the line card of hardware resource (commonly referred to as in this block
The source line card of detection) on generate, the protection being usually configured generally has a list item in all line cards, such as protecting tunnel group, tunnel
The list item of pipe protection group all has in all line cards, but needs to pay close attention to customer instance port during general test performance
Line card where (Customer Instance Port, CIP), because flow walks CIP, if the protection of line card is cut where CIP
Change if not coming into force, will occur this flow cutout, so detection source line card generate alarm, need alarm notification to
Other line cards, other line cards are also required to trigger protection switching after receiving alarm.Alert broadcast can guarantee certainly to all line cards
Line card where CIP also receives warning information and switches over.
In usually realizing, different alarm sources wants trigger protection to switch, and is required for alarm cross-line card broadcast a set of in this way
Mechanism, in this case just redundance unavoidably, is also required in addition be further added by mechanism a set of in this way, no when increasing a kind of alarm newly
Good extension multiplexing.Because IAS is the system that is uniformly processed of alarm, at the same IAS all alarms be all integrated into one it is unified
Alarm represents structure, as long as so IAS realizes alarm cross-line card broadcast mechanism, other have newly-increased alarm that can all answer
With.
When alarm inputs to IAS, if the alarm needs IAS to carry out cross-line card broadcast, as long as cross-line card will be alerted
Broadcast flag set, if it is not needed, can not set.
After step 302, alarm input to IAS, IAS carries out some simple Effective judgements to alarm first, for example accuses
Whether alert state is correct, and whether physical port, tunnel ID of alarm etc. are effective etc., some illegal invalid inputs are carried out
Filtering；
After step 303, alarm Effective judgement, IAS is according to the unified representation method alerted, by the various alarms of input
The unified alarm parameter structures of IAS are converted to, after being converted into unified alarm parameter structure, in all processing procedures of IAS systems,
Unify alarm parameter structure using this and carry out various processing；
Step 304, the Slurry pump based on aforementioned IAS alarm cross-line card broadcast flags, IAS are judged in alarm sender
Alarm whether need the mark that IAS cross-lines card is broadcasted, if the flag set, which is subjected to the broadcast of IAS cross-lines cards,
If the no set of the mark, IAS does not carry out the alarm cross-line card broadcast, other line cards receive the announcement after the broadcast of cross-line card
Police is also required to carry out various hand-off process；
Step 305, alarm input to IAS, and main purpose is exactly trigger protection switching, if alarm source is switched fast work(
Can switch it is enabled, then carry out IAS and be switched fast processing, whether alarm source rapid switching function here, which switchs to open to order, matches
Put it is specified, according to user need can make the rapid switching function of IAS that can be cut according to alarm source, IAS others functions also have
Corresponding order configuration switch, is also based on this consideration；
IAS rapid switching functions, mainly according to the level of alarm, lookup is effectively protected resource information, and notice corresponds to
Protection mechanism triggering switching, after IAS will alert unified representation, various protection mechanisms have been indifferent to the detection source of alarm, root
According to level (alarm level uniquely corresponds to the detection object entity of alarm) trigger protection switching of alarm, reference can be made to shown in Fig. 2, example
Such as, if alarm is tunnel level, for detection, the alarm source of detection can be the TMP layers detection of TMPLS OAM, either
Tunnel BFD are detected, and the object entity of two kinds of detection method detections is tunnel, and essence is detection tunnel failure, and for protecting
Shield, the failure of tunnel level can be switched over configured tunneling technique protection group, as long as tunnel failure, just trigger protection switches, for
Alarm source is without being concerned about.
If the quick breeding function switch of step 306, alarm source is enabled, carrying out IAS, quickly breeding is handled, and IAS is quick
It is the alarm of service layer to breed major function, notifies that, to client layer, client layer generates service layer's fault alarm, while client layer
Trigger protection switches；
For TMPLS OAM, if TMS layers generate alarm, at TMP layers without configuration detection of connectivity (Continuity
And Connectivity Check, CCCV) under conditions of (if TMP layers have configuration detect, do not need to breed, by detecting
Carry out trigger protection switching), TMS layers of alarm needs to be advertised to TMP layers, and TMP layers generate service layer's failure (SSF) alarm, simultaneously
TMP layers if there is configured tunneling technique protection group, then need to carry out protecting tunnel group switching.TMP layers to TMC layers of breeding function with
TMS layers to TMP layers of breeding function is similar, if TMP layers generate alarm, under conditions of TMC layers of no configuration CCCV (if
TMC layers have configuration to detect, then do not need to breed, and are switched by detecting come trigger protection), while situation about can not be protected at TMP layers
Under (TMP layers do not have protecting tunnel group protect or protecting tunnel group active/standby tunnel fail), need to TMC layer breeding, TMC layers
SSF alarms are generated, while TMC layers are protected if there is FRR is configured, then carry out FRR protection switchings, FRR protections here can make
The VPN FRR protections of two layers of either three layers of PW FRR protections.
Breeding function so that in the case where client layer does not play detection, if service layer fails, client layer also can be normal
Trigger protection switches.
If step 307, alarm source fast m apping functional switches enable, IAS fast m apping processing is carried out,
IAS fast m apping functions are mainly that access link (AC) side failure is mapped to PW sides, then trigger PW FRR protections and cut
It changes, service traffics is protected not interrupt；
The schematic diagram of IAS fast m apping functions is as shown in figure 4, AC1 failures (down), PE2 perceive AC1down, pass through
PW1 sends mapping message to PE1, and PE1 receives mapping message (representing AC1 failures), then triggers PW FRR switchings, stream
Amount is switched to from main PW1 on standby PW2.
Notice is sent there are mainly two types of the modes of mapping messages in PE2 equipment, and one kind is that TMPLSOAM sends client's letter
Number failure (Client Signal Fault, CSF) message mode, it is a kind of be BFD send diagnostic sampling word set CV messages side
Formula.If the mapping modes of TMPLS OAM are configured, when AC sides failure generates, PE2 equipment periodics send CSF message, opposite end
PE1 equipment receives CSF message, triggering PW FRR switchings, and during the fault recovery of AC sides, PE2 equipment stops sending CSF message, PE1
Equipment does not receive CSF message in 3 times of sending cycle time intervals of CSF message, then it is assumed that fault recovery, triggering PW FRR are returned
It cuts.If what is be configured is the mapping modes of BFD, when AC sides failure generates, PE2 equipment sends the CV messages of diagnostic sampling word set,
Wherein for diagnostic sampling word reversely to fail for 8 expression AC sides to failure, diagnostic sampling word before 6 expression AC sides, diagnostic sampling word represents AC sides pair for 14
To failure, opposite end PE1 equipment receives the BFD CV messages of diagnostic sampling word set, triggering PWFRR switchings, when the fault recovery of AC sides
When, PE2 equipment sends the CV messages that diagnostic sampling word is 0, and PE1 equipment receives the CV messages that diagnostic sampling word is 0, then it is assumed that failure is extensive
It is multiple, trigger PW FRR switchbacks.
If the quick binding function switch of step 308, alarm source is enabled, carrying out IAS, quickly binding is handled, and IAS is quick
Binding major function is that, by static OAM binding configuration technologies, the OAM detections specified by entrance (ingress) are as triggering
Event links to trigger the OAM detections specified another outlet (egress).The inspection of the ingress and egress of configuration
Many kinds can be included by surveying, for example the technology detected can be TMPLS OAM, BFD, CFM, MPLS OAM, port events etc.,
Different bind commands is configured, can be applicable in different networking scenes, the work that trigger protection is switched during playing network failure
With.For example the basic functional principle of bright binding function, Fig. 5 are a kind of networking scenes of binding function application below, and PE2 is set
Standby AC sides configuration CFM detections, PW sides configuration TMC detections, while bind command ingress is configured and is detected for CFM, egress is
TMC is detected, and when AC sides CFM detects failure, by the bind command being configured, directly linkage to TMC, the detection of TMC is also set to
Failure, opposite end PE1 equipment also perceive TMC failures, triggering PW FRR protection switchings at once.
All it is to reflect AC sides failure as binding function plays the role of with mapping functions under this networking scene
PW sides are mapped to, triggering PW FRR switch, unlike, mapping functions are the binding functions by way of message interaction notice
It is the mode that static configuration directly links, certainly, the application scenarios of binding function are far above this one kind, and the configuration of bind command is very
Flexibly, it can be applied to the network failure protection in a variety of network environments.
In conclusion the major function that the processing method of above-mentioned alarm provides includes rapid switching function, quickly breeds work(
Energy, fast m apping functions, quick binding function, alarm cross-line card broadcast capability etc., these functions are mainly used in different groups
In net scene, after network failure, protection network is played rapidly in the alarm of energy quick response detection, trigger protection switching
