One of the core concepts of the embodiments of the present invention is proposed referring to Fig. 5 a and Fig. 5 b based on the above-mentioned characteristic of view networking, The embodiment of the present invention is applied to the scene of view networked server and multiple view networked terminals, it then follows the agreement for regarding networking, by making With reusable communication handle (above-mentioned communication handle based on view networked server MAC Address and view networked terminals MAC Address), Reduce creation and destroy communication handle bring resource overhead, and in the thread pool by being created in server initiation Thread monitor and safeguard the queue of reusable communication handle and inactive queue of task, equally reduce creation and destroying threads Bring resource overhead；Further, referring to shown in Fig. 5 b, during establishing connection, by the thread in thread pool to The view networked terminals of application connection distribute communication handle, and above-mentioned communication handle is recycled after disconnecting.

Embodiment one:

Referring to shown in Fig. 6, the embodiment of the present invention one provides a kind of view networked resources management method, and the method is applied to In networking, including step 601-603:

Step 601: view networked server monitors communication handle queue and inactive queue of task；The communication handle passes through The MAC Address initialization of the MAC Address and view networked terminals of the view networked server；The inactive queue of task is used to delay Deposit the resource request of view networked terminals to be processed.

The main thread of the view networked server monitors communication handle queue and inactive queue of task；The communication handle It is initialized by the MAC Address of the view networked server and the MAC Address of view networked terminals, the MAC Address, that is, hardware Location, this is because what the characteristic of view networking determined, because mostly using interchanger depending on the connection in networking, and interchanger work is in number 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 wait locate Reason task queue is used to cache the resource request of view networked terminals to be processed, and the money of high concurrent in the short time can be effectively treated Source request.

When the view networked server initializes, need to create communication handle queue in case using, that is, Shen in advance Please memory source, it is first that the communication handle needs the MAC Address of MAC Address and view networked terminals by regarding networked server Beginningization.

When the view networked server initializes, it is also necessary to create thread pool by host process, can repair according to actual needs Change the quantity of thread in created thread pool, 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.Also to do some relevant initialization operations during creating thread pool, for example, creation it is described to Task queue is handled, addition mutex (is equivalent to unlock and locks, for guaranteeing thread-safe, avoid two or more threads Will not be by concurrent invocation) or semaphore (it is same to be used to guarantee thread-safe, it is used to when there is task arrival, main thread is used to call 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, which listens in inactive queue of task, just will do it processing 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, starting the idle thread is worker thread, handles the setting event 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, four threads can be run simultaneously for the CPU of four cores, if listening to the resource of view networked terminals A Request, then idle thread 1 is waken up as worker thread 1 in thread pool, i.e., will be described for parsing and caching the resource request Resource request is encapsulated as task A with corresponding communication handle, and is placed 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 by logical Believe that handle returns to the resource data, and is recovered as idle thread after the completion of execution；If listening 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 It can be the thread 2, be also possible to other threads being in idle condition；It is not intended to limit the line for parsing the resource request The thread of journey, resource request corresponding with the task is handled is same thread.

Step 603: when disconnecting depending on networked terminals, recycling the corresponding communication handle of the view networked terminals.

When disconnecting depending on networked terminals, the view networked server recycles the corresponding communication sentence of the view networked terminals Handle.Generally, the communication handle that the view networked terminals can be monitored by the main thread depending on networked server, listens to Request is disconnected, the disconnection request can be handled by the thread in thread pool, and recycle the communication handle.

The embodiment of the present invention includes following advantages:

It should be noted that for simple description, therefore, it is stated as a series of action groups for embodiment of the method It closes, but those skilled in the art should understand that, embodiment of that present invention are not limited by the describe sequence of actions, because according to According to the embodiment of the present invention, some steps may be performed in other sequences or simultaneously.Secondly, those skilled in the art also should Know, the embodiments described in the specification are all preferred embodiments, and the related movement not necessarily present invention is implemented Necessary to example.

Embodiment two:

Referring to shown in Fig. 7, second embodiment of the present invention provides a kind of view networked resources management method, the method is applied to In networking, including step 701-709:

Step 701: if the connection request for receiving view networked terminals depending on networked server, enables in thread pool One idle thread is worker thread, to handle the connection request.

If the main thread depending on networked server receives the connection request of view networked terminals, enable in thread pool One idle thread is worker thread, to handle the connection request；The connection request includes the MAC of the view networked terminals Address and view networked terminals number, the view networked terminals number of the MAC Address of the view networked terminals and the view networked terminals It is all uniquely, to be corresponded with the view networked terminals, the mark as view networked terminals.

Step 702: receiving and parsing through the connection request of the view networked terminals, the view in the connection request is joined The MAC Address and view networked terminals number of network termination, are compared, described in confirmation with the information depending on networked terminals of storage Depending on the connection permission of networked terminals.

The worker thread depending in networked server thread pool receives and parses through the connection request of the view networked terminals, The MAC Address and view networked terminals number of the view networked terminals in the connection request are obtained, and is networked according to the view The MAC Address of terminal searches the corresponding view networked terminals number of storage, or according to the view networked terminals number searching pair The MAC Address for the view networked terminals answered, finds the corresponding information of the view networked terminals of storage in a word, and is compared, If the MAC Address, the view networked terminals number are identical as the corresponding informance of storage, the view networked terminals are confirmed With connection permission, step 703 is executed；If the MAC Address, it is described have any difference depending on networked terminals number, confirm It is described not connect permission depending on networked terminals, then terminate.

Step 703: a communication handle is obtained from view connected network communication handle queue, according to the view networked server The MAC Address of MAC Address and the view networked terminals initializes the communication handle, and returns to permission by the communication handle The response of networking.

The worker thread depending in networked server thread pool, which obtains one from depending on connected network communication handle queue, not to be had The communication handle being initialised, the MAC Address according to the MAC Address of the view networked server and the view networked terminals are initial Change the communication handle, certainly, described be identified depending on networked terminals has connection permission；Then it is returned by the communication handle Return the response for allowing to network.

Step 704: view networked server monitors communication handle queue and inactive queue of task；The communication handle passes through The MAC Address initialization of the MAC Address and view networked terminals of the view networked server；The inactive queue of task is used to delay Deposit the resource request of view networked terminals to be processed.

Step 705: if listening to the resource request of corresponding view networked terminals by communication handle, enabling in thread pool An idle thread be worker thread, by the communication handle receive and parse through it is described view networked terminals resource request.

If listening to the resource request of the view networked terminals corresponding to the communication handle by communication handle, line is enabled An idle thread of Cheng Chizhong is worker thread, and the resource of the view networked terminals is received and parsed through by the communication handle Request.

Step 706: the resource request of the view networked terminals and corresponding communication handle being encapsulated, waiting task is put into Queue is medium to be processed.
