Embodiment
Basic thought of the present invention is on two endpoint devices in tunnel, for trooping in many tunnel creation tunnels of same paths; The tunnel trooped to be tied to detect on the management group of entities; When physical link was unusual, the management entity group was trooped current detection state notifying tunnel, trooped and accomplish batch process according to said detected state in the tunnel.
For a better understanding of the present invention, at first introduce application scenarios of the present invention.Fig. 1 is the application scenarios structural representation of many same paths tunnels of the present invention centralized management method; As shown in Figure 1; Equipment 101 all passes through equipment 102, equipment 104 and equipment 106 simultaneously to existing four tunnels to be respectively Tunnel 1, Tunnel 2, Tunnel 3 and 4, four static tunnels of Tunnel between the equipment 108.The business that these tunnels are responsible for has nothing in common with each other, and for example: Tunnel 1 is responsible for network telephone service, Tunnel 2 is responsible for video Data Transmission business, Tunnel 3 responsible fixed telephone services, Tunnel 4 responsible BT downloading services.But the operating path in four tunnels is identical, basic scene according to the invention.Therefore can between equipment 101 and equipment 108, create tunnel Tunnel list 1 that troops.For static tunnel, the deployment of MEG only produces corresponding response at the head node in tunnel.So Tunnel list only need be in the tunnel of correspondence two end points, equipment 101 gets final product with equipment 108 deploy.
Below in conjunction with accompanying drawing and specific embodiment technical scheme of the present invention is further set forth in detail.
Fig. 2 is the method flow sketch map of the present invention's a kind of many same paths tunnels centralized management, and as shown in Figure 2, said method specifically comprises:
Step 201 is on two endpoint devices in tunnel, for trooping in many tunnel creation tunnels of same paths;
Concrete, troop and comprise in said tunnel: troop type, tunnel cluster management entity of tunnel cluster number, tunnel bound interface, tunnel number statistics, tunnel cluster state, tunnel information database.Wherein, said tunnel cluster number is used for the index of trooping as this tunnel, when creating the tunnel and troop, gives tunnel cluster number of this cluster assignment by endpoint device; The said tunnel type of trooping is used to the type of specifying this tunnel to troop, and the type of trooping is divided into two kinds, a kind ofly is used for this layer detection (TMP Detect) of trooping in the tunnel, and (TMS Detect) detects in the lower floor that another kind is used for trooping in the tunnel; Said tunnel cluster management entity is bound interface; The inlet of the notice that is used for changing as the tunnel cluster state, if troop in the tunnel type be to channel layer (T-MPLS Path, TMP); Then need in this layer of trooping, bind the detection mode of appointment; Type is that (T-MPLS Section TMS), then need bind the tunnel of appointment and troop in the corresponding TMS of the lower floor of trooping to the section layer if troop in the tunnel; Said tunnel number statistics is used to write down concentrated how many bar tunnels of having bound of current tunnel group; Said tunnel cluster state is used to write down the state of trooping in current tunnel, and the state of trooping in the tunnel has four kinds, is respectively Signal Fail alarm (SF), Signal Degrade alarm (SD), the Signal Fail that occurs behind Signal Degrade alarm (SF-SD), signal alarm normal (OK); Said tunnel information database is used to write down current tunnel group and concentrates the tunnel information index of having bound, all tunnels in notice was trooped when convenient state of trooping in the tunnel changed.
Step 202 is trooped the tunnel to be tied to and is detected on the management group of entities;
Concrete, said binding specifically is to bind interface through said tunnel cluster management entity, is trooped and tunnel group concentrates the management entity group in each bar tunnel to bind in the tunnel.Further, also need the type of configured tunneling technique cluster as required, need the tunnel of response TMP to troop, then dispose this layer detection, need the tunnel of response TMS to troop, then dispose lower floor and detect.In the present invention, trooping in two kinds of tunnels is mutual exclusion, therefore needs configuration respectively.Said detection management group of entities comprises: a kind of is this layer detection module, is used to detect terminal device access path current state, and through the OAM packet sending and receiving between the agreement realization equipment.Wherein, said agreement can be detection protocol such as TMPLS OAM or BFD.Trooping after this layer detection module of binding possess corresponding relation in the tunnel, could guarantee correctly to report detected state.Another kind is lower floor's detection module, for the detected state that lower floor is upwards announced in alarm detects in the lower floor of TMP.It is TMS that entity detects in the lower floor of trooping in current tunnel; Trooping in the tunnel needs to respond the alarm status that send on lower floor's detection module; The outgoing interface that then need guarantee TMS is identical with the outgoing interface of tunnel correspondence; And after this TMS has registered corresponding lower floor's announcement relation through tunnel cluster management entity binding interface, could guarantee correctly to report the detected state of lower floor.
Further, after trooping and create in the tunnel, said method also comprises: need add the tunnel in new tunnel when trooping, judge whether the existing tunnel information of concentrating with tunnel group matees, if coupling then add, otherwise would add failure.
Concrete, the tunnel adds checks at first when trooping that tunnel group concentrates the information that whether has comprised other tunnels, if there are not other tunnels in trooping, directly the tunnel joined and troops; If contained the tunnel in trooping; Take out article one tunnel and the tunnel that needs to add; The essential information in two tunnels is compared,, also need check the demonstration route (ERO) in tunnel for dynamic tunnel if pattern (sound attitude), type (single-direction and dual-direction), outgoing interface, next jumps all unanimity then join tunnel group and concentrate; Different then the interpolation failed, and returns the user and adds failure.Above method can only judge for static tunnel whether the local terminal in tunnel is consistent, but can't guarantee same path really.Concrete topology needs configuration person to guarantee.
Step 203, when physical link was unusual, the management entity group was trooped current detection state notifying tunnel, and troop and accomplish batch process according to said detected state in the tunnel.
Concrete, said detected state specifically is to send through the form of warning information.Trooping and receive detected state in the tunnel, promptly calculates the corresponding tunnel alarm status of trooping behind the warning information, compares with existing alarm status then, if alarm status is not then announced the tunnel that tunnel group is concentrated, process ends with current identical; If different with existing alarm status, then upgrade the alarm status of trooping in the tunnel, and all concentrated tunnels of announcement tunnel group, upgrade tunnel state, accomplish batch process.Said batch process specifically comprises: the tunnel cluster is notified the tunnel that is comprised in the tunnel information database one by one, switches for the tunnel that has protection, and on equipment, prints alarm.
Further; The tunnel is clustered in and upgrades the current state that need not be concerned about the tunnel in the tunneling process; The tunnel is when joining the protecting tunnel cohort, and alarm status can directly be updated to the tunnel current states of trooping, and it is consistent in whole flow process, to remain the alarm status of trooping with the tunnel.After the tunnel broke away from the tunnel and troops, the current alarm state in tunnel was eliminated in the tunnel group rally, and with the alarm status equipment initial value in tunnel, new alarm status is notified by the MEG on the tunnel again.After the tunnel obtains new alarm status, write down this state.If not in the protecting tunnel group, and there is the corresponding upwards configuration of announcement in the tunnel, then the tunnel is to the new alarm status of upper strata TMC announcement.The tunnel adds the tunnel to troop before, different if troop in the state in tunnel and tunnel, and the announcement tunnel of trooping, the tunnel that causes upgrades alarm status and also can trigger this operation.If the tunnel is present in the protecting tunnel group, then new alarm status is notified to the protection group in the tunnel, and the protection group is according to the new protection group switching state of the protection policy calculation of correspondence and carry out respective operations.If corresponding upwards announcement configuration is arranged on the tunnel, same, the tunnel can be to the new alarm status of upper strata TMC announcement.The tunnel adds the tunnel to troop before, different if troop in the state in tunnel and tunnel, and the announcement tunnel of trooping, the tunnel that causes upgrades alarm status and also can trigger this operation.
The method flow sketch map that Fig. 3 troops current detection state notifying tunnel for management entity group of the present invention, as shown in Figure 3, said method comprises:
Step 301, unusual when the physical link generation, the detection module on the link calculates corresponding alarm and reports, if this layer detection module, then execution in step 302; If lower floor's detection module, then execution in step 304;
Concrete, said can be unusually pull out fibre, close port, to lose the message that reason such as route causes obstructed unusual, also can be because the message signals deterioration that other interference cause, the too high generation of the error rate unusual.
Step 302 judges whether said management entity group troops with the tunnel to have set up binding relationship that if set up binding, then execution in step 303, if do not bind then handle according to prior art.
Step 303 judges whether the type of trooping in the tunnel is this layer detection, if, then troop delivering to the tunnel on the warning information, and process ends, if being set to lower floor, the type of trooping in the tunnel detects, then troop and do not do response in the tunnel;
Step 304, lower floor's detection module upgrades the alarm status of self, troops delivering to the tunnel on the warning information.
Concrete; TMS receive can search this TMS after the alarm upwards announce object; To bind the type that interface is bound and troop in the tunnel with tunnel cluster management entity be lower floor's type of detection when the interface of upwards announcing of this TMS, and then troops delivering to the tunnel on the warning information.
