T-MPLS technology is the standardized a kind of Packet Transport Network (PacketTransportNetwork of International Telecommunication Union (ITU-T), PTN) transmission technology, be characterized in a kind of technology of connection-oriented grouping queries, its data retransmission face is multiprotocol label switching (MultiProtocolLabelSwitching, MPLS) a subset, forwards based on T-MPLS label.It simplifies some sophisticated functions in MPLS data retransmission face; eliminate IP-based without connecting forwarding characteristic; and add connection-oriented operation, management, safeguard (Operation, Administration, Maintenance; OAM) function of function and protection recovery; and using ASON/general multiple protocols mark exchange agreement (AutomaticallySwitchedOpticalNetwork/GeneralizedMultiprot ocolLabelSwitching, ASON/GMPLS) as its chain of command.And " SCCP connection-oriented " this feature means that T-MPLS technology can provide the service of telecom operation level, require to possess the OAM(Operation Administration Maintenance) suitable with traditional transport network.Therefore OAM(Operation Administration Maintenance) just becomes the requisite key link of T-MPLS technology.
At present according to the definition of ITU-TRecommendationG.8114/Y.1373 standard, OAM is based on detection management group of entities (MaintenanceEntityGroup end to end, MEG) be configured, namely tunnel deploy T-MPLSOAM detects.Such deployment can play supervisory function bit to the state in this tunnel, to notify user in time when exception appears in tunnel, such as, on user's configuration interface and network management interface, prints alarm; Take appropriate measures and to detect fault, diagnose, locate and fault recovery etc., such as tunnel carries out protection and to switch or upper layer application is noticed in tunnel.
The OAM mechanism of T-MPLS has following features: 1, each OAM detection management entity needs the T-MPLS specified to connect support.2, support client layer/service layer OAM relation, need corresponding configuration mode at every aspect.3, ISP wants automatically to detect, notify the fault relevant to maintenance entity.4, must take appropriate measures when fault occurs.
In actual applications, due to the difference of business or the difference of user's request, the tunnel of many same paths may be there is for identical two end points, corresponding tunnel all needs dispose corresponding detection management group of entities and carry out OAM measuring ability end to end.Make the MEG through upper equivalent effect has appearred going the same way mutually in corresponding T-MPLS action scope, such deployment adds OAM Protocol Data Unit (ProtocolDataUnit in network, PDU) redundancy, when network simultaneously in this path occurs abnormal, each MEG needs to print alarm on user's configuration interface and network management interface, adds the burden of equipment.

Embodiment
Basic thought of the present invention is in two endpoint devices in tunnel, for trooping in many tunnel creation tunnels of same paths; Is trooped in tunnel and be tied in detection management group of entities; When physical link is abnormal, current detected state is notified to troop in tunnel by management entity group, troops and complete batch process according to described detected state in tunnel.
For a better understanding of the present invention, application scenarios of the present invention is first introduced.Fig. 1 is the application scenarios structural representation of the present invention's many same paths tunnel centralized management methods, as shown in Figure 1, there are four tunnels between equipment 101 to equipment 108 and be respectively Tunnel1, Tunnel2, Tunnel3 and Tunnel4, four static tunnels are simultaneously all through equipment 102, equipment 104 and equipment 106.These tunnels the business be responsible for different, such as: Tunnel1 is responsible for network telephone service, Tunnel2 is responsible for video data transmission business, Tunnel3 is responsible for fixed telephone service, Tunnel4 is responsible for BT downloading service.But the operating path in four tunnels is identical, basic scene according to the invention.Therefore can create a tunnel to troop Tunnellist1 between equipment 101 and equipment 108.For static tunnel, the head node of deployment only in tunnel of MEG produces corresponding response.So Tunnellist only needs at two, the tunnel of correspondence end points, equipment 101 and equipment 108 deploy.
Below in conjunction with the drawings and specific embodiments, the technical solution of the present invention is further elaborated.
Fig. 2 is the method flow schematic diagram of the present invention's a kind of many same paths tunnels centralized management, and as shown in Figure 2, described method specifically comprises:
Step 201, in two endpoint devices in tunnel, for trooping in many tunnel creation tunnels of same paths;
Concrete, troop and comprise in described tunnel: troop type, tunnel cluster management entity binding interface, tunnel number statistics, tunnel cluster state, tunnel information database in tunnel cluster number, tunnel.Wherein, described tunnel cluster number, for the index of trooping as this tunnel, when create tunnel troop time by endpoint device give this cluster assignment tunnel cluster number; Troop type in described tunnel, be used to specify the type trooped in this tunnel, type of trooping is divided into two kinds, and a kind of this layer of trooping for tunnel detects (TMPDetect), and (TMSDetect) detects in the another kind of lower floor being used for trooping in tunnel; Described tunnel cluster management entity binding interface, for the entrance of notice changed as tunnel cluster state, if troop in tunnel, type is for channel layer (T-MPLSPath, TMP), then need in the detection mode of binding in this layer and specifying of trooping, if troop in tunnel, type is for section layer (T-MPLSSection, TMS), then need in the TMS that lower floor of trooping is corresponding, bind the tunnel of specifying and troop; Described tunnel number statistics, has bound how many tunnels for recording during current tunnel is trooped; Described tunnel cluster state, for recording the state that current tunnel is trooped, the state trooped in tunnel has four kinds, be respectively Signal Fail alarm (SF), Signal Degrade alarm (SD), the Signal Fail alarm (SF-SD) occurred after Signal Degrade, signal alarm normal (OK); Described tunnel information database, for recording during current tunnel is trooped the tunnel information index bound, notifies to troop interior all tunnels when convenient state of trooping in tunnel changes.
Step 202, troops tunnel and is tied in detection management group of entities;
Concrete, particular by described tunnel cluster management entity binding interface, to troop and tunnel group concentrates the management entity group in each bar tunnel to bind in tunnel by described binding.Further, also need the type of configured tunneling technique cluster as required, need the tunnel responding TMP to troop, then configure this layer and detect, need the tunnel responding TMS to troop, then configure lower floor and detect.In the present invention, trooping in two kinds of tunnels is mutual exclusion, therefore needs to configure respectively.Described detection management group of entities comprises: one is this layer of detection module, for detecting terminal device access path current state, and by the OAM message transmitting-receiving between protocol realization equipment.Wherein, described agreement can be the detection protocol such as TMPLSOAM or BFD.Tunnel troop binding this layer of detection module possess corresponding relation after, guarantee correctly reports detected state.Another kind is lower floor's detection module, and the detected state that lower floor is upwards noticed in alarm detects in the lower floor for TMP.It is TMS that entity detects in the lower floor that current tunnel is trooped, trooping in tunnel needs to respond the alarm status that lower floor's detection module send, then need to ensure that the outgoing interface that the outgoing interface of TMS is corresponding with tunnel is identical, and after this TMS have registered corresponding lower floor's notice relation by tunnel cluster management entity binding interface, guarantee correctly reports the detected state of lower floor.
Further, after trooping and create in tunnel, described method also comprises: need to add tunnel in new tunnel when trooping, judge whether the existing tunnel information concentrated with tunnel group mates, if mated, add, otherwise add unsuccessfully.
Concrete, tunnel adds when trooping and first checks that tunnel group concentrates the information whether containing other tunnels, if do not have other tunnels in trooping, is directly joined in tunnel in trooping; If containing tunnel in trooping, take out the tunnel of Article 1 tunnel and needs interpolation, the essential information in two tunnels is compared, if pattern (sound state), type (single-direction and dual-direction), outgoing interface, down hop are all consistent, join tunnel group and concentrate, the explicit routing to tunnel (ERO) is also needed to check for dynamic tunnel, different, add failure, return user and add failure.Above method can only judge that for static tunnel whether the local terminal in tunnel is consistent, but cannot really ensure same path.Concrete topology needs configuration person to ensure.
Step 203, when physical link is abnormal, current detected state is notified to troop in tunnel by management entity group, troops and complete batch process according to described detected state in tunnel.
Concrete, described detected state sends particular by the form of warning information.Trooping and receive detected state in tunnel, namely calculates corresponding tunnel after warning information and to troop alarm status, then contrast with existing alarm status, if alarm status is identical with current, then do not notice the tunnel that tunnel group is concentrated, process ends; If different with existing alarm status, then upgrade the alarm status of trooping in tunnel, and notice the concentrated all tunnels of tunnel group, upgrade tunnel state, complete batch process.Described batch process specifically comprises: tunnel cluster notifies the tunnel comprised in tunnel information database one by one, switches, and print alarm for the tunnel that there is protection on equipment.
Further; tunnel is clustered in the current state upgrading in tunneling process and do not need to be concerned about tunnel; tunnel is when joining protecting tunnel cohort, and alarm status directly can be updated to tunnel and to troop current state, and in whole flow process, remain that the alarm status of trooping with tunnel is consistent.After trooping in disengaging tunnel, tunnel, the current alert state in tunnel is eliminated in tunnel group rally, and by the alarm status equipment initial value in tunnel, new alarm status is notified again by the MEG on tunnel.After tunnel obtains new alarm status, record this state.If tunnel is not in protecting tunnel group, and have the corresponding configuration upwards noticed, then new alarm status is noticed to upper strata TMC in tunnel.Tunnel adds to before tunnel troops, the difference if troop in the state in tunnel and tunnel, and troops and notice tunnel and upgrade alarm status and also can trigger this operation in the tunnel caused.If tunnel is present in protecting tunnel group, then tunnel notifies new alarm status to protection group, and protection group calculates new protection group switching state according to the Preservation tactics of correspondence and carries out respective operations.If tunnel there is corresponding upwards notice configuration, equally, new alarm status can be noticed to upper strata TMC in tunnel.Tunnel adds to before tunnel troops, the difference if troop in the state in tunnel and tunnel, and troops and notice tunnel and upgrade alarm status and also can trigger this operation in the tunnel caused.
Fig. 3 is the method flow schematic diagram that current detected state notifies to troop in tunnel by management entity group of the present invention, and as shown in Figure 3, described method comprises:
Step 301, when physical link produces abnormal, the detection module on link calculates corresponding alarm and is reported, if this layer of detection module, then performs step 302; If lower floor's detection module, then perform step 304;
Concrete, described exception can be pull out the obstructed exception of message that the reasons such as fibre, close port, loss route cause, and also can be because other disturb the message signals deterioration caused, the exception of the too high generation of the error rate.
Step 302, judges that whether described management entity group troops with tunnel and establishes binding relationship, if establish binding, then perform step 303, if not binding, conventionally process.
Step 303, judges whether the type of trooping in tunnel is that this layer detects, and if so, then troops warning information being delivered to tunnel, and process ends, detect if the type trooped in tunnel is set to lower floor, then troop and do not respond in tunnel;
Step 304, the alarm status of lower floor's detection module renewal self, troops warning information being delivered to tunnel.
Concrete, the upwards notice object of this TMS can be searched after TMS receives alarm, when this TMS upwards notice interface with tunnel cluster management entity binding interface binding and the type trooped in tunnel is lower floor's type of detection, then troop warning information being delivered to tunnel.
