Description
Technical field
The present invention relates to communication field, relate in particular to a kind of method that Timer (timer) task is managed.
Background technology
Need the system of Timer task on a large scale at some, such as, among the iSAP server (IntegratedService Application Platform server, a carrier-class use in conjunction/service platform), need to create a large amount of Timer tasks, be used for carrying out Timing Processing.Said system realizes often having following two characteristics for Timer:
1, needs to support a large amount of Timer tasks.With SIP (Session InitiatedProtocol, initial session protocol) is applied as example, each calls out the Timer task that approximately needs more than 10, therefore, the quantity of the Timer task that whole system need be supported is often above 10000, even more, under the situation of top load, need to support to surpass 20000 Timer task.
2, Jue Daduoshuo Timer task will trigger in a short period of time.In typical SIP used, the Timer task triggering cycle above 50% was 500 milliseconds.Simultaneously, Jue Daduoshuo Timer task has the fixing triggering cycle.For example, with 500 milliseconds be the Timer task in cycle account for sum greatly about 60%, 1 second being that the Timer task in cycle accounts for 20% of sum greatly, with 2 seconds be the cycle account for 5% of sum greatly, with 4 seconds be the cycle account for 1% of sum greatly.
A kind of method that the Timer task is managed is in the prior art: based on the Timer task management method of balance heap.The structural representation of balance heap can be referring to Fig. 1.This method is used a task queue in whole system, formation adopts the balance heap to sort according to triggered time of task, has very high ordering efficient, is log at the ordering complexity of each insertion and deletion Timer task operating
2N (N represent to pile in the total quantity of Timer task).Element queue[n in the heap] two children be respectively queue[2*n] and queue[2*n+1].Task minimum in the heap is queue[1]. for each the element node n in the heap, we suppose that its child is d, and the triggered time of node n necessarily is less than or equal to the triggered time of child d so.When a new task was inserted in this heap, heap was reset balanced tree automatically and is guaranteed that this task is placed on the correct position.When a task was deleted, balanced tree was reset remaining task.
The shortcoming of the above-mentioned method that the Timer task is managed is: because whole system is used a Timer task queue, the triggering cycle of each Timer task is inequality, need be to the Timer task ranking, and ordering needs the regular hour cost.Along with increasing Timer task is inserted into, the length of formation can be more and more longer.Therefore, the also corresponding prolongation of time that single inserts or deletion Timer task operating needs will cause the continuous decline of systematic function.
Summary of the invention
The purpose of this invention is to provide a kind of method that the Timer task is managed, thereby can reduce the time that single inserts or deletion Timer task operating needs, improve the efficiency of management of Timer task.
The objective of the invention is to be achieved through the following technical solutions:

Embodiment
The invention provides a kind of method that the Timer task is managed, core of the present invention is: create one or more fixed cycle task of timer formations in system, utilize this fixed cycle task of timer formation that the task of timer that has the certain trigger cycle in the system is managed.
Describe the present invention in detail below in conjunction with accompanying drawing.
The handling process of the embodiment 1 of the method for the invention comprises the steps: as shown in Figure 2
Step 2-1, at least one fixed cycle task of timer formation of establishment in system.
The Timer task is triggered by the Timer thread, introduces the effect of Timer thread below earlier.
The realization of Timer task is based on the Timer task queue.System is that each Timer task queue distributes a Timer thread, and this thread is responsible for dispatching the task in the Timer task queue.If the Timer thread finds in the formation Timer task is arranged, so, it is just taken out the nearest Timer task that needs to trigger, and does following inspection then:
If the triggered time of 1 Timer task is to be less than or equal to the current time, then trigger this Timer task at once.
If the triggered time of 2 Timer tasks is greater than the current time, after then this thread will be waited for corresponding time difference value (triggered time-current time), trigger this Timer task again.
In the time of waiting for, if there is new Timer task to be inserted into, the Timer thread can obtain notice, so, the Timer thread can be waken up, and takes out nearest Timer task of triggered time again in formation, continues to wait for or trigger (depending on the triggered time of this Timer).Why will retrieve the Timer task, be because the Timer task that just has been inserted into may have the littler triggering cycle.Certainly, Timer thread based on fixed cycle task of timer formation can not need to carry out this operation, because the Timer task triggered time of the new fixed cycle task of timer formation of creating is later than original Timer task certainly, unless do not have the Timer task in the original formation.
The present invention at first classifies to the Timer task in the system based on the triggering cycle of Timer task.By the Timer task in the system is classified,, just this triggering cycle is configured to the fixed cycle in case a large amount of Timer tasks with identical triggering cycle is arranged in the discovery system.
Then, in system, create the cycle timer task queue of described fixed cycle correspondence, and distribute to thread of this cycle timer task queue, in system, can create a plurality of fixed cycle task of timer formations.For example, can create two fixed cycle task of timer formations in the system, triggering cycle is 500 milliseconds, and triggering cycle is 1 second.
In actual applications, also the triggering cycle of fixed cycle task of timer formation can be configured in xml (extend markup language) configuration file of system, when system start-up, corresponding fixed cycle task of timer formation just can be created according to the triggering cycle information of the configuration in the xml configuration file by system.
Task of timer in the fixed cycle task of timer formation carries out ascending order according to its triggered time to be arranged, and the task in the formation obtains ordering automatically according to its triggered time.Fixed cycle task of timer formation can realize that its structural representation can be referring to Fig. 3 by a doubly linked list.
Step 2-2, task of timer is put into the fixed cycle task of timer formation identical with its triggering cycle manage.
In this example, when a Timer task was created in the system, the Timer Facility in the system (timer equipment) determined at first according to the triggering cycle of this task which formation is this Timer task should put into.If system be this task the triggering period allocated corresponding fixed cycle task of timer formation, then this Timer task is inserted in the corresponding fixed cycle task of timer formation.
Fixed cycle task of timer formation is a FIFO (First in, first out, first in first out) formation, can realize by a doubly linked list, because the operating time of doubly linked list is a constant, irrelevant with the length of formation, this has guaranteed that system can support more load.As shown in Figure 4, the fixed cycle task of timer formation based on doubly linked list has three kinds of basic operations:
1, insert: the Timer task in the fixed cycle task of timer formation all has the identical triggering cycle, and is to insert with the order of creating.Therefore, when needs insert the fixed cycle Timer task of a new establishment, because its triggered time is late than previous insertion necessarily, so, directly this Timer task being inserted tail of the queue gets final product, do not need to remake any ordering work, whole formation remains arranges according to the triggered time ascending order.
2, deletion: when a Timer task is cancelled, directly this Timer task is deleted from formation and get final product.The same with above-mentioned insertion operation, deletion action does not need to remake any ordering work yet.
3, trigger:, just mean that this Timer task need be triggered in case the Timer thread waits of a Timer task is finished.This Timer thread will obtain a thread and come this Timer task of asynchronous execution from thread pool.Then, directly from head of the queue this task is deleted, the Timer thread obtains next Timer task again from the Timer formation.
The triggering cycle for the Timer task in the system is not a lot of situation, by creating limited corresponding fixed cycle timer queue, can finish the management of Timer task very efficiently.
The handling process of the embodiment 2 of the method for the invention comprises the steps: as shown in Figure 5
Step 5-1, in system, create fixed cycle task of timer formation and general timer task queue simultaneously.
This embodiment is applicable in the system except the Timer task in the certain trigger cycle with some also have the situation of the bigger Timer task of a large amount of triggering cycle excursions.Such as the system that uses based on the telecommunications of SIP that needs the Timer task on a large scale.
In the present embodiment, in system except will creating several embodiment 1 described fixed cycle timer queues, also to create a general timer task queue, be used to manage the not all task of timer identical with the triggering cycle of fixed cycle timer queue.
The general timer task queue is used balance to pile and is realized, sorts according to the triggered time of task, determines element in the formation according to digital coordinates.Element queue[n in the general timer task queue] two children be respectively queue[2*n] and queue[2*n+1], task minimum in the heap is queue[1], for each the element node n in the heap, we suppose that its child is d, and the triggered time of node n necessarily is less than or equal to the triggered time of child d so.
The general timer task queue can also adopt other method to realize, as realizing with the double-purpose chained list, the Timer task in the chained list is directly sorted by the triggered time.
Step 5-2, task of timer is put into fixed cycle task of timer formation respectively and the general timer task queue manages.
When a Timer task is created in the system, if the triggering cycle of this Timer task has been configured to fixed cycle task of timer formation, then this Timer task is inserted in the corresponding fixed cycle task of timer formation, this Timer task is managed according to embodiment 1 described management method; Otherwise, this Timer task is inserted in the general timer task queue, in the general timer task queue, this Timer task is managed.
General timer task queue for using the balance heap to realize also has insertion, deletion and three kinds of operations of triggering.When a new Timer task was inserted in this heap, heap was reset balanced tree automatically and is guaranteed that this task is placed on the correct position.After a Timer task is triggered, need this Timer task deletion.When a Timer task was deleted, balanced tree was reset remaining Timer task, to satisfy the requirement of general timer task queue.
In this embodiment,, be put in the fixed cycle task of timer formation, reduced the length of general timer task queue greatly owing to there is a large amount of Timer tasks from the general timer task queue, to separate with certain trigger cycle.Therefore, the insert or delete operation of general timer task queue also because formation shortens and correspondingly accelerates, has significantly reduced the ordering pressure of general timer task queue.Particularly to the system of the Timer task that has a large amount of same period, this advantage is very obvious.Thereby for whole system provides good performance.
Such as, adopt the described method of this embodiment, by in iSAP Server, creating 500 milliseconds, 1 second, 2 seconds, 4 seconds the fixed cycle timer queue and the general timer task queue of employing balance heap realization respectively, under very high load, iSAP server can support to surpass 20000 Timer task.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
