[0031] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0032] Figure 1 This is a flowchart of a method for dynamically scheduling a dongle based on USB network redirection provided by an embodiment of the present invention. Figure 1 , this embodiment may include the following steps:

[0033] S101, setting the encryption dongle on the node machine corresponding to the forwarding client through the USB port.

[0034] Among them, the encryption dongle on the node machine corresponding to the forwarding client can be shared with the node machine corresponding to the non-forwarding client under the management of the forwarding server.

[0035] S102, obtaining and parsing the dongle information reported by the node machine corresponding to the forwarding client, and storing the parsed information in a database.

[0036] S103, based on the information in the database, respond to the dongle use request sent by the node machine corresponding to the non-forwarding client, and enable the node machine corresponding to the non-forwarding client to share the dongle on the node machine corresponding to the forwarding client through USB Over Network.

[0037] The invention provides a method for dynamically scheduling an encryption dongle based on USB network redirection, which comprises the following steps: setting the encryption dongle on a node machine corresponding to a forwarding client via a USB port; wherein the encryption dongle on the node machine corresponding to the forwarding client can be shared with a node machine corresponding to a non-forwarding client under the management of a forwarding server; obtaining and parsing encryption dongle information reported by a node machine corresponding to the forwarding client, and storing the parsed information in a database; based on the information in the database, responding to an encryption dongle use request sent by a node machine corresponding to a non-forwarding client, enabling the node machine corresponding to the non-forwarding client to share the encryption dongle on the node machine corresponding to the forwarding client via USB Over Network, thereby improving the management effect of the encryption dongle, and improving the management efficiency by setting a plurality of node machines corresponding to forwarding clients.

[0038] In the embodiment of the present application, the forwarding client can be set on multiple node machines to perform the same operation, so as to improve the efficiency of using the dongle under the management of the forwarding server, wherein the operation of the node machine corresponding to each forwarding client specifically includes the following:

[0039] First, at startup, the local device is traversed to query all preset types of USB devices and obtain the corresponding device information, which includes the instance address, name, port, location and status of the device. Based on the device information, a target list is generated and the target list is used as the dongle information.

[0040] Specifically, in the present application, the USB forwarding client software, i.e. the forwarding client mentioned above, can be installed on a node machine, wherein the machine should have multiple USB ports and an external USB hub, i.e., the machine has the ability to insert N USB dongles, and there can be multiple such node machines.

[0041] After completing the above arrangement, the node machine of the forwarding client traverses the local device at startup and queries all preset type devices on it, such as all USB devices with human-machine interface device class 3-0-0 (Class-Subclass-Protocol), obtains the device's instance address, name, port, location (such as 1:1:1 / 3:1:4), status and other information and stores them in a target list such as list L, where the location information can be used as a unique identifier for the corresponding device (it should be noted that before or after generating the list, devices can be filtered, such as filtering out USB devices that are dongles).

[0042] Then the node machine of the forwarding client allocates a fixed TCP port number, such as 6000-7000, to each device in the L order of this list.

[0043] Then traverse this list L, use the USB Over Network software to specify the location and TCP port to share the corresponding USB port for external connection. After completion, this machine will listen to N TCP ports. At this time, the USB port that can be used for external connection (such as devices with dongles installed) can be used to share with external machines such as the node machine corresponding to the non-forwarding client.

[0044] At the same time, the node machine corresponding to the forwarding client also connects to the forwarding server through TCP, and reports this list information as the dongle information to the forwarding server for storage. The node machine corresponding to the forwarding client can also start a thread to regularly monitor the plug-in and unplug changes of the USB port of this machine, share or cancel the sharing of the USB port in real time, and synchronously report the change information to the forwarding server. Thus, the operation of the node machine corresponding to the forwarding client is completed.

[0045] On this basis, the process of the node machine corresponding to the non-forwarding client using the dongle in the node machine corresponding to the above-mentioned forwarding client includes: when the dongle needs to be used, sending a dongle use request to the forwarding server; when the forwarding server returns the dongle information, mounting the corresponding dongle by calling the USB Over Network software; and after the use of the dongle is completed, calling the USB Over Network software to uninstall the dongle, and sending a dongle uninstall request to the forwarding server.

[0046] Specifically, there are also multiple node machines corresponding to the non-forwarding client, which are the authorization verification working end. When it needs to use the dongle, that is, it needs to verify the dongle, it first sends a dongle use request to the forwarding server to request an idle dongle (this step may require a loop request to wait for allocation); when there is an idle dongle information returned, call the USB Over Network software to mount this remote dongle; and after use, call the USB Over Network software to uninstall this remote dongle, and send a request to the forwarding server.

[0047] Correspondingly, on the forwarding server side, it can respond to the dongle usage request sent by the node machine corresponding to the non-forwarding client based on the information in the database, including: when receiving the dongle usage request sent by the node machine corresponding to the non-forwarding client, querying the dongle information with an idle status from the corresponding database, setting the status of this dongle to busy, and returning the dongle information to the node machine of the non-forwarding client; when receiving the dongle uninstallation request sent by the node machine corresponding to the non-forwarding client, setting the dongle status to idle in the database, and returning the result to the node machine corresponding to the non-forwarding client.

[0048] Specifically, the forwarding server can be set up in only one place. In actual applications, the forwarding server is started and listens to the specified TCP port P1 (used for the forwarding client to report the dongle status) and the specified TCP port P2 (used by the non-forwarding client to request an idle dongle); the client (i.e., the forwarding client and the non-forwarding client) is connected in a loop, the reported information is parsed, and stored in the database. At this time, the database contains the information of the dongle to be scheduled. When the mount request of the non-forwarding client arrives, the information of an idle dongle is queried from the database, and the status of this dongle is set to busy, and the result is returned to the non-forwarding client; when the uninstall request of the non-forwarding client arrives, the status of this dongle in the database is idle, and the result is returned to the non-forwarding client.

[0049] Based on the same inventive concept, the present application also provides a dongle dynamic scheduling system based on USB network redirection, including: a forwarding client and its corresponding node machine, a forwarding server and its corresponding node machine, a forwarding server and corresponding devices, used to execute the dynamic dongle scheduling method based on USB network redirection in the above method embodiment.
