DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to solve the problem that the startup speed of the network management client is slow in the prior art, the present invention provides a method and an apparatus for implementing the startup acceleration of the network management client, and the present invention is further described in detail below with reference to the accompanying drawings and embodiments. . It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The user login to the NMS client is divided into two phases: The first phase: The user clicks the executable program to the login page of the network management client; The second phase: The user inputs relevant information on the login interface, clicks the confirmation and then performs the client. Log in until the network management client interface is presented. The speed of these two phases is directly related to the user experience. Therefore, in the first phase of the login of the network management client, the network management client can be effectively accelerated. In the second phase, the user interface can be fully utilized. At the same time, the client login initialization work is performed in the background, which can effectively accelerate the startup time of the network management client and improve the user experience satisfaction. Based on these features of the network management system, the acceleration of the network management client startup is crucial. Based on this, an embodiment of the present invention provides a method and an apparatus for implementing startup acceleration of a network management client, which are described in detail below through specific embodiments. The embodiment provides a method for implementing the acceleration of the network management client startup. FIG. 1 is a flowchart of a method for implementing the startup acceleration of the network management client according to the embodiment of the present invention. As shown in FIG. 1 , the method includes the following steps (steps). S102-Step S104): Step S102: After detecting that the user clicks on the executable program of the network management client, the acceleration process is started to query whether the prepared background process exists. If yes, the network management client is displayed according to the prepared background process. The login interface is normal; if no, the display operation of the login interface is performed normally; Step S104, after the login interface is displayed, the startup acceleration process uses the time when the user inputs the parameter on the login interface, and synchronizes the network management client startup in the background. The previous initialization operation. In this embodiment, the network management client startup includes two phases: the first phase is that the user clicks on the executable program to present to the network management client login interface; the second phase is that the user inputs relevant parameters on the login interface, and clicks the confirmation. Until the network management client interface is presented. The object of the invention is to accelerate in these two phases. And to meet the characteristics of the network management system multi-client, to achieve multi-client startup acceleration in the operating system multi-session. Through the technical solution of the present invention, the network management client acceleration process is started, managed, and recovered, and the deployment file is started by periodically pre-reading the network management client, thereby speeding up the reading and writing speed and consolidating the startup acceleration effect. When the network management client is installed in the embodiment of the present invention, an operating system level service is created, that is, the acceleration process is started. This process starts automatically after the NMS client installation is complete. Start the acceleration process on multiple sessions of the operating system, start the network management client initialization process, initialize the client startup in the background, load the client deployment files and images, and initialize the various views of the client. After all the initialization work is completed, enter the wait state, periodically pre-read the network management client startup file, avoiding the long-term non-logging of the network management client, causing the operating system memory to be occupied by other applications, waiting for the network management client to be officially started. . Based on this, the embodiment provides a preferred implementation manner, that is, preferably, before detecting an executable program that the user clicks on the network management client, the method further includes: a startup acceleration service of the network management client, and an operating system session meeting the specified condition. On, create a startup acceleration process. Preferably, after the startup acceleration process is created, the method further includes: starting a startup deployment file of the pre-reading network management client of the acceleration process; and starting the deployment file for the startup operation of the network management client. Preferably, the startup configuration file of the periodic pre-reading network management client includes: pre-reading the startup deployment file at a fixed time; or pre-reading the startup deployment file at a specified time according to the field experience value; or analyzing the network management client The time period during which the terminal starts frequently, during which the startup deployment file is periodically pre-read. When the user clicks on the client executable program, it first communicates with the startup acceleration process, asking if there is a background process that has been prepared. If it is ready, the background waiting process will display the client login interface, and click the client from the user. The executable program is displayed to the client login interface, only the time consumption of the interface presentation, and the initialization of the client startup, configuration file and image loading, view initialization, etc., are completed ahead of the startup acceleration process and wait in the background. If the client officially starts the process and the startup acceleration process communicates that the background acceleration process is not ready for the client startup initialization, the client officially starts the process and starts the normal process. This process includes the startup acceleration process. All initialization work initiated by the client. After the client login interface is displayed, the startup acceleration process will use the time when the user inputs parameters in the interface, and synchronize the initialization operation before the client starts in the background to further accelerate the client startup. The startup acceleration process is not only responsible for managing the acceleration process started on each session of the operating system, but also after the network management client runs, exits, takes over the network management client process, releases some unnecessary resources, and waits for the next login. The network management client process is equivalent to a startup acceleration process. Based on this, the present embodiment provides a preferred implementation manner, that is, the method further includes: after the network management client runs, start the process of the acceleration process to take over the network management client, release unnecessary resources, and wait for the network management client. Log in next time. The steps of the client-side acceleration method of the carrier-class network management system provided in this embodiment are as follows: Step A: When the network management client is installed, the user configures the acceleration to be started in advance according to the performance of the operating system (such as cpu, memory, etc.). The number of processes and the number of sessions allowed to be optimized on the operating system. Step B, create an operating system level service, that is, start the acceleration service (also known as the startup acceleration process). In step C, the startup acceleration service is started under the following conditions: After the network management client is installed; after the operating system is started. In order for the client startup acceleration to take effect, the startup acceleration service should always be kept up. Step D: Start the network management client acceleration process on the operating system session according to the parameters configured by the user during the installation phase, perform initialization of the client startup, load the configuration file and the image deployed by the client, and initialize various views of the client, and complete After the initialization is started, it waits in the background of the operating system. Step E: Before the user clicks to run the program, the client initialization process initiated in the background is always waiting in the background, and the network management client deployment file is periodically pre-read according to a certain method, even if the user does not officially start the network management client for a long time. The client initialization process in the background also ensures that the deployment file is always flushed out of other applications in memory, ready for the official login of the network management client. Step F, the user clicks the executable program to start the network management client, communicates with the startup acceleration process, asks to start the acceleration process, whether the prepared client startup acceleration process has completed the initialization of the client startup, and if so, the network management client The parameters required for the incoming startup start the acceleration process for the client, and the client login interface is presented. The process that the client officially starts is exited, and the client starts the acceleration process before starting the acceleration service, and completes the client login. When the user inputs the relevant parameters on the login interface, the last initialization work before login is performed simultaneously in the background. Step G: The startup acceleration service determines whether it is necessary to start a startup acceleration process on the operating system session for client initialization according to the parameters configured by the user during installation, and is used to wait for the next client to log in. Step H: The network management client runs for a period of time. When exiting, the acceleration service is started to recover the client process, part of the resources are released, and the client process is taken over as the acceleration process when the client is officially logged in next time. The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings. 2 is a block diagram of a carrier-class network management client startup acceleration service management according to an embodiment of the present invention. As shown in FIG. 2, a specific operation procedure of a carrier-class network management client to start an acceleration service is as follows: Step 101: Start an acceleration service in an operating system. On a session, start a startup acceleration process. The process is responsible for the initialization of the client startup, and after preparation, periodically pre-reads the deployment files required by the client to start, and waits for the user to officially click the executable program to start the network management client. In step 102, the user clicks on the executable program to officially start the client. At this point, the client will communicate with the startup acceleration process, asking if the initialization is complete and ready. If the startup acceleration process feedback has completed initialization, the startup acceleration service displays the client login interface. Step 103: The user inputs corresponding parameters on the login interface, and the parameter input is performed at the same time, and the initialization work before the official login of the client is performed in the background. Step 104: After the client runs, exit, and the acceleration service will reclaim the client process, release a part of the resources, re-manage the process, wait for the next user login, and use as the startup acceleration process. FIG. 3 is a general flowchart of a carrier-class network management client performing acceleration in two stages of startup according to an embodiment of the present invention. As shown in FIG. 3, the process includes the following steps (step S302-step S316): Step S302, a client The end startup acceleration service starts. Step S304, the client initiates the acceleration service to start a process on an operating system session that meets the condition, and the process is responsible for performing startup initialization of the client. Step S306, after the initialization of the client is completed, periodically pre-reading the deployment file initiated by the network management client, putting the file into the cache, speeding up the I/O reading speed, and periodically pre-reading according to a certain algorithm. The file is taken because the user does not start the network management client for a long time after the startup initialization is ready. Other applications may occupy the operating system memory. According to the specific conditions of the network management system, different methods can be used for periodic pre-reading. For example, pre-reading can be performed at regular intervals, or pre-reading can be performed at certain time points according to field experience values. Automatic analysis of the network management client to start a frequent period of time for flexible periodic pre-read operations. In this way, a better network management client startup optimization effect is achieved. In step S308, the user clicks on the executable program to perform a formal login. At this point, the client that is in the waiting state is started to initiate the initialization process, and the client login interface is presented. In step S310, the client login interface is presented. This is the first phase of the network management client startup. This phase itself includes initialization of the client startup, reading of files and images, and so on. However, these initialization tasks have been completed in advance by the client startup acceleration process, so the first phase of the client startup is from the perspective of the user experience, and only the time consumed by the login interface is consumed. Step S312, and step S314, are performed simultaneously, and are the second phase of the network management client startup. When the user inputs the parameter on the client login interface, the background initialization operation of the client official login is also performed. Played a role in accelerating the second phase of client startup. Step S316, after the client runs, exit, and the network management client starts the acceleration service to reclaim the client process, release some unnecessary resources, and re-manage the client process, which can be regarded as the next client before the official startup. The initialization process prepares for the next startup acceleration of the official client login. FIG. 4 is a detailed flowchart of a carrier-level network management client startup acceleration according to an embodiment of the present invention. As shown in FIG. 4, the process includes the following steps (step S402-step S436): Step S402: Perform network device client installation. Step S404, in the process of installing the network management client, the user inputs the parameter of the client startup acceleration according to the actual performance of the operating system (such as the performance of resources such as cpu and memory). For example, the network management client acceleration process can be started on m operating system sessions. In the same operating system session, the n startup acceleration processes are always ready, and the client is officially started. Step S406, after the operating system is restarted, the network management client starts the acceleration service to start automatically. In addition, after the network management client installation is completed, the service will also start automatically. Step S408, creating an operating system service, where the service is responsible for managing the acceleration process of the network management client on each operating system session. Step S410: Determine, according to the parameter input in step S404, whether the network management client initialization process needs to be started on the operating system session. Step S412, if the network management client initialization process does not need to be started on the operating system session, the process exits. Step S414, if the network management client initialization process needs to be started on the operating system session, the process is started and the initialization of the client startup is performed. Step S416, after the initialization of the client is started, if the user does not officially start the network management client for a long time, the memory is likely to be occupied by other applications, and according to a certain method, the pre-reading network management client starts deployment. Files, waiting for the client to officially log in, can further improve the client startup acceleration effect. In step S418, it is determined whether a client is started, and communicates with the client initialization process. If the client is not officially started, it continues to wait, periodically pre-reads the file, and if so, wakes up the waiting initialization process. In step S420, the user clicks on the executable program of the network management client to officially start the network management client. Step S422, the client officially starts the process and communicates with the client initialization process, and asks whether the initialization process that is ready is available. If yes, the client login interface is presented, and the startup operation of the network management client is continued. If not, the feedback is given to The client officially starts the process, and the client officially starts the process to do the client startup initialization and subsequent work. Step S424, the client officially starts the process to determine whether the ready acceleration process can be used by using the feedback information of the client initialization process. Step S426, if the ready client starts the initialization process, the client officially starts the process to be closed, and the subsequent work is handed over to the network management client initialization process that has been started before. Step S428, if the client initiates the initialization process feedback has not completed initialization, the client officially starts the process itself to perform initialization and the like. Step S430, the client officially starts the process to wake up the client initialization process in the waiting state, and presents a client login interface. The user inputs parameters on the login interface, and the client logs in and runs. In step S432, the client exits. Step S434, if there is no client initialization process ready, the network management client officially starts the process to complete the client login and runs, and finally exits. Step S436, after the client exits, the network management client acceleration service recycles the process, releases a part of the unnecessary resources, and then re-manages the network management client process, and uses it as a client to start the acceleration process, and performs the next client login. ready. Corresponding to the implementation method of the network management client startup acceleration introduced in the foregoing embodiment, the embodiment provides a device for implementing the startup acceleration of the network management client, and the device is used to implement the foregoing embodiment. FIG. 5 is a structural block diagram of an apparatus for implementing acceleration of a network management client according to an embodiment of the present invention. As shown in FIG. 5, the apparatus includes: a first acceleration module 10 and a second acceleration module 20. The structure is described in detail below. The first acceleration module 10 is configured to: after detecting that the user clicks on the executable program of the network management client, query whether there is a background process that is prepared, and if yes, display the login interface of the network management client according to the prepared background process; No, the display operation of the login interface is normally performed; the second acceleration module 20 is connected to the first acceleration module 10, and is configured to synchronize the network management client in the background by using the time when the user inputs the parameters on the login interface after the login interface is displayed. Initialization before startup. Preferably, the apparatus further comprises: a creating module, configured to create a startup acceleration process on an operating system session that meets the specified condition. Preferably, the device further includes: a pre-reading module, configured as a pre-reading deployment file of the pre-reading network management client; wherein the startup deployment file is used for the startup operation of the network management client. Preferably, the pre-reading module comprises: a first pre-reading unit, configured to pre-read the startup deployment file every fixed time; or, the second pre-reading unit is configured to pre-read at a specified time according to the field experience value. Take the starter The third pre-reading unit is configured to analyze the time period during which the network management client starts frequently, and the startup deployment file is periodically pre-read during the time period. Preferably, the device further includes: a processing module, configured to take over the process of the network management client after the operation of the network management client ends, release the unnecessary resources, and wait for the next login of the network management client. Compared with the prior art, the technical solution provided by the present invention creates an operating system level service to manage the network management client startup acceleration process on each session, and supports multi-network management client startup acceleration on multiple operating system sessions, and is flexible. According to the performance of the operating system, the number of accelerated processes that can be started and the number of sessions of the operating system are accelerated. This can achieve a good balance between the startup acceleration of the network management client and the occupation of operating system resources. Start the acceleration process After the client is initialized, periodically read the files related to the login of the NMS client according to a certain method, so that when the user does not officially log in to the NMS client for a long time, the file can still be read from the memory and the network management client can be accelerated. Start up. When the user starts the network management client through the executable program, different boot parameters can be sent to the startup acceleration service that is already in the waiting state, so as to start the multi-network management client under the multi-operating system session, after the network management client exits. The startup acceleration service can reclaim the client process, release some resources, and continue to manage the client process to wait for the next network management client to start optimization. In addition, the technical solution of the present invention divides the startup of the network management client into two phases. The first phase is from the user clicking the executable program to the network management client login interface, and the network management client initiated by the acceleration service can be initialized at this stage. The initialization operation in the process reaches the acceleration of the startup; the second phase is presented from the login interface, the user inputs the relevant parameters on the interface to confirm the login, and finally displays the network management client interface, and the user uses the time of the user input interface parameters in the background. At the same time, the initialization of the login of the network management client is performed. The invention utilizes two stages of the network management client startup, and respectively accelerates to achieve the final result. It is known that a startup acceleration service is installed under the operating system. When the user does not start the network management client, the service performs the initialization operation initiated by the network management client in advance in the background, and has certain occupation of the operating system resources. Start the acceleration service to start a process on a session of the operating system. When the client initiates initialization, the client is officially started on another session. It cannot be accelerated by the startup of another session. It can be flexibly controlled by starting the acceleration policy. You can start a process to accelerate on each session, or you can accelerate only on the latest session of the operating system. All of the above problems can be considered by the user when the NMS client is installed (such as the central processing unit ( After Central Processing Unit (CPU), memory and other performance), flexible configuration to achieve a balance between startup acceleration and operating system resource usage. While the preferred embodiments of the present invention have been disclosed for purposes of illustration, those skilled in the art will recognize that various modifications, additions and substitutions are possible, and the scope of the invention should not be limited to the embodiments described above. Industrial Applicability As described above, the problem that the startup speed of the network management client in the related art is slow is solved, and the startup acceleration of the multi-client on the operating system multi-session is realized, and the deployment file is started by periodically pre-reading the network management client. Speed up the reading and writing speed and consolidate the startup acceleration effect.
