Referring to FIG. 1, a diagram of an operating environment of a network device in a preferred embodiment of the present invention is shown.

In the present embodiment, the network device 1 and the network server 3 communicate via the network 2. The network server 3 transmits the packet to the network device 1 through the network 2, and the network device 1 parses the content of the received packet, learns the information of the process of processing the packet, and dynamically enables the corresponding process according to the information. Handle the packet.

Referring to FIG. 2, it is a hardware structure diagram of the network device of the present invention. The network device 1 includes a processor 10, a memory 11, a parsing module 12, an inquiry module 13, an execution module 14, an update module 15, a processing module 16, a listening module 17, and a timing module 18. The memory 11 stores the database 110, and the information of each process can be stored in the database 110 in a hash table or other manners convenient for recording and searching. The process information refers to the name, status, and the like of the process. The state of the process includes both on and off states. The processor 10 is configured to control a corresponding module to implement a function of dynamically enabling a process.

The parsing module 12 is configured to parse the content of the packet when the network device 1 receives the packet, and learn the process for processing the packet.

The query module 13 is configured to query whether the data of the process for processing the packet is recorded in the database 110, and the information includes the name and status of the process. If there is a record in the database 110 that processes the packet, the query module 13 queries the status of the process.

The execution module 14 is used to turn on or off the corresponding process. When the process that needs to process the packet is in the off state, the execution module 14 will start the process. When the process continues for the unprocessed packet to reach the preset end time set by the timing module 18, the execution module 14 will close the process.

The update module 15 is configured to update information of each process in the database 110, including recording information, deleting information, and updating the status of the process to be turned on or off. When the query module 13 queries the information in the database 110 that the process of processing the packet is not available, the update module 15 records the information of the process in the database 110, including the name and status of the process, and the status of the process. Update to off. When the operating system is shut down, the update module 15 deletes the information of all processes in the database 110. When the process is changed from the off state to the on state, the state of the corresponding process recorded in the repository 110 is updated to on. When the process is changed from the on state to the off state, the state of the corresponding process recorded in the repository 110 is updated to off.

The processing module 16 is configured to call the process in the open state to process the packet.

The listening module 17 is configured to listen to whether the network device 1 also receives other packets that also need to be processed by the process.

The timing module 18 is configured to set a preset end time, for example, the preset end time It is 10 seconds. The timing module 18 is further configured to time the duration of the unprocessed packet for the process, and determine whether the duration of the process for the unprocessed packet reaches the preset end time set. If the preset end time is 10 seconds, it is determined whether the duration of the process for the unprocessed packet reaches 10 seconds.

Referring to FIG. 3, it is a flow chart of a preferred embodiment of a method for dynamically enabling a process by a network device of the present invention. The timing module 18 presets a preset end time, such as the preset end time being 10 seconds.

In step S100, when the network device 1 receives the packet, the parsing module 12 parses the content of the packet to learn the information of the process of processing the packet.

In step S101, the query module 13 queries whether the information of the process corresponding to the packet is recorded in the database 110. If the information of the process is not recorded in the database 110, the process proceeds to step S102. If the information of the process is recorded in the database 110, the process proceeds to step S103.

In step S102, the update module 15 records the information of the process of processing the packet in the database 110, and updates the status of the process to off.

In step S103, the query module 13 determines whether the process is in an open state according to the information of the process queried in the database 110. If the process is in the on state, the process proceeds to step S106, if the process is in the closed state. Then, the process proceeds to step S104.

In step S104, the execution module 14 starts the process.

In step S105, the update module 15 updates the status of the process in the database 110 to an on state.

Step S106, the processing module 16 calls the process to process the received packet.

In step S107, the interception module 17 listens to whether the network device 1 also receives other packets that also need to be processed by the process. If the network device 1 further receives another packet that needs to be processed by the process, the process returns to step S106. If the network device 1 does not receive another packet that needs to be processed by the process, the process proceeds to step S108.

In step S108, the timing module 18 times the duration of the unprocessed packet for the process. Specifically, the timing starts from 0. If the network device 1 does not receive other packets that need to be processed by the process until the time when the process continues to process the unprocessed packet reaches the preset end time, the timing continues. If the network device 1 receives another packet that needs to be processed by the process before the process continues to process the unprocessed packet, the time for the process to continue processing the unprocessed packet is restarted from 0. . For example, the preset end time is set to 10 seconds. If the network device 1 receives another packet that needs to be processed by the process when the duration of the unprocessed packet for the process is 5 seconds, the timing module 18 The time period for the process to continue unprocessed packets starts from 0; if the network device 1 has not received other packets that need to be processed by the process if the time for the process to continue unprocessed packets is 5 seconds, The timing module 18 continues to time the time period for which the process continues unprocessed packets and then 5 seconds before the previous time.

In step S109, the timing module 18 determines whether the time during which the process continues unprocessed packets reaches the preset end time set. If the process does not reach the preset end time, the process returns to step S107. If the process continues for the unprocessed packet, the process proceeds to step S110.

In step S110, the execution module 14 closes the process.

In step S111, the update module 15 updates the status of the process in the database 110 to the closed state.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
