Embodiment 5
The N time slot of supposing TE Link AB is remaining time slot, and the N time slot free time of node A, and the N time slot of Node B is remaining time slot.When setting up new business connection, service path is through TE Link AB, and mark should business be Call-1.At this moment, the Link Resource Manager module applying label of node A can be successful, but when the Link Resource Manager module applying label of Node B, can return time slot label application failure.Preset remaining time slot threshold time is T in the control plane of network element, and T value can be provided with through configuration file configuration or other modes, and T value is in the back continuously effective of control plane startup, and we are provided with this and are worth and are 12S usually.Start remaining time slot in Node B this moment and detect, referring to Fig. 4, testing process is following:
S402, beginning;
S404, Call-1 is in the success of A end application N time slot;
S406, Call-1 is in the failure of B end application N time slot;
S408 judges whether the N time slot of B end belongs to management plane, is execution in step S410 then, otherwise execution in step S412;
S410 forces to be allocated to control plane to the N time slot of B end, and execution in step S422;
S412 judges whether B end N time slot has distributed to other business, otherwise execution in step S414, is execution in step S416 then;
S414, fault processing flow process, and execution in step S424;
Whether S416 judges T0 more than or equal to T, otherwise execution in step S418, is execution in step S420 then;
S418, label competition process flow process, and execution in step S424;
S420 removes the N Time Slot Occupancy situation of B end;
S422 gives Call-1 the N time slot allocation of B end;
S424 finishes.
Wherein, the time of record current business Call-1 applying label is T1;
Whether the N time slot of inspection Node B belongs to management plane is used.Use if this time slot belongs to management plane, show that the N time slot is that user's mistake when resource allocation is divided causes, be the N time slot migrating of Node B that control plane uses this moment, gives professional Call-1 label distribution then.Professional then Call-1 continues to apply for downstream distributing labels, and final new business connects to be set up successfully.
Use and do not distribute to other professional connections uses if the N time slot of Node B belongs to control plane, then get into the fault processing flow process.Use and distributed to other professional connections uses if the N time slot of Node B belongs to control plane, suppose business to be Call-2.Check that professional Call-2 distributes the successful time of N time slot, suppose that this time is T2.
Deduct T1 with T2 and obtain time T 0, i.e. T0=T2-T1.Continue to detect by following flow process:
A) if T0 >=T, the N time slot of predicate node B is exactly remaining time slot so.Though this time slot has been distributed to professional Call-2, having detected this time slot is remaining time slot, therefore directly removes and then distribute to professional Call-1 to this time slot.Professional Call-1 continues to apply for downstream distributing labels, and final new business connects to be set up successfully.
B) if T0＜T judges that so the N time slot of B end is not remaining time slot, but an other professional Call-3 from B to A is competing the N time slot that B holds with Call-1.Get into label competition process flow process this moment.Under this situation, by following principle distributing labels: (1) is preferentially given the business of recovering the time slot allocation of competition.This principle has guaranteed that the business of having opened can recover success the most fast.Article (2) two, when business all is new business, distribute time slot by the self-defining principle of system.Such as preferentially giving the little business of node ID label distribution.
Embodiment 6,
Referring to Fig. 5, user resources are divided mistake when causing remaining time slot, and N time slot A end belongs to control plane to be used, and the B end belongs to management plane to be used, and M time slot A end belongs to management plane to be used, and the B end belongs to control plane to be used.When business during from A to B direction applying label, for the M time slot, use, so the Link Resource Manager module of A end can not give this traffic assignments M time slot because the A end belongs to management plane, also just need not carry out remaining time slot detection to this time slot.For the N time slot; Because A end belongs to control plane, if the Link Resource Manager module assignment of A end the N time slot, when the B end distributes the N time slot; Detect this time slot and belong to management plane, so this time slot must be the remaining time slot that the resource division of user error causes.For such remaining time slot, only need directly to force to be allocated to control plane to this time slot and use, give professional getting final product this time slot allocation by the Link Resource Manager module of B end again.
Referring to Fig. 6, when network meltdown caused remaining time slot, T0 represented this applying label and the last time difference that becomes this label of the distribution of work.Remaining to connect threshold time T be an empirical value, and this value is to provide after taking into full account the scene of remaining time slot and resource contention appearance.N time slot A end is idle, and the B end has been distributed to other business, and M time slot A end has been distributed to other business, and B holds idle.When business from A to B direction applying label the time, for the M time slot, because A end has been distributed to other professional uses, so the Link Resource Manager module of A end can not give this traffic assignments M time slot, just need not carry out remaining time slot detection to this time slot yet.For the N time slot because A end is idle, if the Link Resource Manager module assignment of A end the N time slot, when the B end distributes the N time slot, detect this time slot and distributed to other professional uses.We know that the appearance of common remaining time slot needs the long period reason that occurs from remaining time slot, this time is minimum all be minute more than, maybe be in actual ASON network in the sky.For the situation of label competition, just can occur when having only both direction almost to apply for same label simultaneously, this moment, the N time slot of B end was just just distributed to Call-2, and time difference T0 is Millisecond normally.Therefore, as T0 >=T, can judge that the N time slot of B end is exactly remaining time slot; As T0＜T, can judge it is resource contention.
In sum; Fast detecting and the remaining time slot method of removing and device have well solved the defective of prior art scheme in a kind of ASON network provided by the invention; Conserve system resources greatly; The performance of raising system has reduced the serious problems that system possibly bring because of user misoperation simultaneously.This method is simple and reliable, and the system that realizes this method is through actual test, and the result is reliable and stable.
