With reference to shown in Fig. 6, the embodiment of the present invention one provides one kind and regards networked resources management method, and the method is applied to
Depending in networking, including step 601-603：
Step 601：Communication handle queue and inactive queue of task are monitored depending on networked server；The communication handle passes through
The MAC Address regarding networked server and the MAC Address initialization regarding networked terminals；The inactive queue of task is used for delaying
Deposit the pending resource request regarding networked terminals.
The main thread regarding networked server monitors communication handle queue and inactive queue of task；The communication handle
It is initialized by the MAC Address regarding networked server and the MAC Address regarding networked terminals, the MAC Address, that is, hardware
Location, this is because regarding networking characteristic determine because using interchanger depending on the connection in networking, and interchanger is operated in number more
According to link layer, and it is connection safety using the advantages of MAC Address, invalid user stealing Internet resources can be prevented；It is described to wait to locate
Reason task queue is used for caching the pending resource request regarding networked terminals, and the money of high concurrent in the short time can be effectively treated
It asks in source.
During the initialization regarding networked server, need to create communication handle queue in case using, that is, Shen in advance
Please memory source, the communication handle needs MAC Address by regarding networked server and regarding at the beginning of the MAC Address of networked terminals comes
Beginningization.
During the initialization regarding networked server, it is also necessary to create thread pool by host process, can repair according to actual needs
Change the quantity of created thread pool thread, and can determine the quantity of thread according to the core of CPU under normal circumstances, example
If core cpu number is N, then for compute-intensive applications, number of threads can be N+1, for I/O intensive type application, thread
Quantity can be 2N+1.Some relevant initialization operations are also done during thread pool is created, for example are treated described in establishment
Task queue is handled, addition mutex (is equivalent to unlock with locking, for ensureing thread-safe, avoids two or more threads
Will not be by concurrent invocation) or semaphore (it is similary to be used for ensureing thread-safe, it is used for when there is task arrival, main thread is used for calling out
Worker thread in awake thread pool)；Resource request can be placed in inactive queue of task thread pool during the work time, work as master
Thread is listened in inactive queue of task and can just be handled when having task arrival, such as can wake up the sky in thread pool
Idle thread carries out task processing.
Step 602：If listening to setting event, the idle thread enabled in thread pool is worker thread, to handle
State setting event.
If the main thread depending on networked server listens to setting event, the idle line in the thread pool is waken up
Journey, starts the idle thread as worker thread, and the setting event is handled by the worker thread.The setting event can be with
Event including resource request further includes the event that task reaches in inactive queue of task, can also include other events.One
As, after the worker thread is finished, being just recycled in thread pool becomes idle thread.The monitoring can pass through prison
The communication handle in the communication handle queue is listened, to listen to resource request event or connection disconnected event, can also be led to
It crosses and monitors the inactive queue of task to listen to corresponding semaphore, that is, listen to the arrival of task, i.e., can account at this time
The task is handled with cpu resource.
For example, for the CPU of four cores, four threads can be run simultaneously, if listening to the resource regarding networked terminals A
Request, then idle thread 1 is waken up as worker thread 1 in thread pool, for parsing and caching the resource request, i.e., will described in
Resource request is encapsulated as task A with corresponding communication handle, and is positioned in the inactive queue of task, then the work
Thread 1 is recovered as idle thread；And in 1 operational process of worker thread, appoint if listening in inactive queue of task
It is engaged in the arrival of B, then idle thread 2 is waken up as worker thread 2 in thread pool, and the worker thread 2 handles the task B, obtains
Corresponding resource request and communication handle are obtained, the resource request is handled, corresponding resource data can be found and passed through logical
Believe that handle returns to the resource data, and is recovered as idle thread after the completion of performing；If listen to inactive queue of task
The arrival of middle task A, then idle thread 3 is waken up as worker thread 3 in thread pool, to handle the task A；The thread 3
